TECHi . Insights
Imagine you have an assistant who can help you brainstorm, write, code, analyze data, or just chat — all in real time. That is exactly what ChatGPT offers, and hundreds of millions of people are already using it every single day.
ChatGPT is a large language model (LLM) developed by OpenAI. Unlike traditional search engines that return links, ChatGPT generates original, human-like text responses by predicting the most likely next word in a sequence, drawing on patterns learned from vast amounts of text data. It was fine-tuned using a technique called Reinforcement Learning from Human Feedback (RLHF), which is why its responses feel remarkably natural and helpful rather than robotic.
But calling ChatGPT “an AI chatbot” drastically undersells what it has become. In 2026, ChatGPT is a platform — a productivity engine, a research assistant, a coding companion, an image generator, a shopping advisor, and increasingly, the central operating system for digital work. With 800 million weekly active users and over 2 billion queries processed daily, it is the fastest-growing consumer application in history. No product — not Instagram, not TikTok, not even Google Search — reached this scale this quickly.
The story of ChatGPT started with a daring experiment by OpenAI, a research lab that aims to ensure artificial intelligence works for the benefit of all humanity. The initial model, powered by GPT-3.5, was released at the end of November 2022 and became a cultural phenomenon virtually overnight. It gained more than 100 million users in its first two months — by comparison, Instagram took approximately 2.5 months to reach 1 million downloads, and Netflix waited around 3.5 years to hit the same milestone.
By now, ChatGPT is not just a chatbot. It is a platform, a productivity tool, and a business engine. OpenAI’s user base spans students, freelancers, Fortune 500 companies, government agencies, and everything in between. The company’s partnership with Microsoft and billions in investment have fueled relentless innovation, culminating in the release of GPT-5 and a suite of capabilities that would have seemed like science fiction just three years ago.
Once starting out as a simple text generator, ChatGPT has become a vibrant tool that serves as a source of creativity, productivity, and automation for millions of users across the globe. Understanding this evolution is key to appreciating where ChatGPT stands today — and where it is headed next.
November 30, 2022 — ChatGPT Launches. Built on GPT-3.5, ChatGPT debuts as a free research preview. It reaches 1 million users in five days and 100 million users within two months, making it the fastest-growing consumer application ever launched. Sam Altman later shared: the team “mercifully” named it ChatGPT and launched it, kicking off “a growth curve like nothing we have ever seen.”
February 2023 — ChatGPT Plus Launches. OpenAI introduces its first paid tier at $20/month, offering priority access and faster responses. The rapid growth had brought server strain, and the subscription model ensured reliable access for power users while funding continued development.

ChatGPT has evolved far beyond text conversations. Here is every major feature available in 2026, explained in detail.
ChatGPT Search enables real-time web browsing with cited sources, effectively turning ChatGPT into a search engine that provides synthesized answers rather than a list of links. Usage has been surging in Europe, where ChatGPT search queries have grown significantly as users discover its ability to provide concise, cited answers. Unlike Google, which returns ten blue links, ChatGPT Search delivers direct, conversational answers with inline citations so you can verify every claim.
ChatGPT’s image generation capabilities exploded in early 2025 when GPT-4o gained native image creation abilities. The numbers are staggering: users generated over 700 million images in a single week, fueled partly by the viral Ghibli-style portrait trend that took social media by storm. The integration of DALL-E within ChatGPT means you can create, edit, and iterate on images through natural conversation — no separate tool required.
Deep Research is an extended multi-step research agent that can browse dozens of websites, analyze hundreds of sources, and compile comprehensive reports — all from a single prompt. It is available to Plus and Pro subscribers, with Pro users getting approximately 120 queries per month. The recent GitHub integration allows Deep Research to pull code repositories, issues, and documentation directly into its analysis, making it invaluable for technical research and competitive analysis.
The ChatGPT Agent (also called Operator) can browse the web, take actions, and complete multi-step tasks autonomously. Need to research competitors, fill out forms, or navigate complex websites? The agent handles it. This represents a fundamental shift from ChatGPT as a question-answering tool to ChatGPT as a task-completing assistant that can operate independently.
Codex is a dedicated coding agent built into ChatGPT that can write, debug, explain, and refactor code across dozens of programming languages. It understands project context, can work with entire codebases, and integrates with development workflows. For developers, Codex transforms ChatGPT from a code suggestion tool into a genuine pair programming partner.
Advanced Voice Mode enables natural, real-time spoken conversation with ChatGPT. It supports multiple voice personalities, detects emotional tone, and can respond with appropriate nuance. The experience feels less like talking to a computer and more like talking to a knowledgeable colleague. Plus and Pro subscribers get video capabilities, allowing ChatGPT to see and respond to what your camera shows.
ChatGPT can now remember preferences, context, and details across conversations. Tell it you prefer concise answers, that you are a Python developer, or that you are working on a specific project, and it will retain that context for future interactions. Memory can be reviewed, edited, or cleared at any time through settings, giving users full control over what ChatGPT retains.
Connectors allow ChatGPT to integrate directly with your existing tools. Connect Google Drive to analyze documents, link Slack to summarize channels, or connect GitHub to review code — all without leaving the ChatGPT interface. Enterprise and Team users can manage connector permissions through the admin console to ensure data governance.
ChatGPT can summarize meetings, extract action items, and generate follow-up emails. Combined with the Google Drive connector, it can pull meeting recordings and transcripts directly, making post-meeting workflows dramatically more efficient.
Custom GPTs let anyone build specialized AI assistants without writing code. Configure a GPT’s instructions, knowledge base, and capabilities, then share it publicly through the GPT Store or keep it private for your team. The GPT Store has become a thriving marketplace, with thousands of purpose-built assistants for everything from legal research to fitness coaching.
Canvas opens a side-by-side workspace where you and ChatGPT can collaboratively write and edit documents or code. Unlike the standard chat interface, Canvas allows inline editing, commenting, and iterative refinement — making it ideal for long-form writing, technical documentation, and code development.
ChatGPT’s Shopping feature provides personalized product recommendations and ad-free comparison shopping. Ask it to find the best laptop under $1,000 or compare running shoes, and it delivers curated recommendations based on reviews, specifications, and pricing — without sponsored results influencing its suggestions.

Integrations with Spotify, Canva, Figma, Expedia, Booking.com, Coursera, and Zillow allow users to interact with popular services directly within conversations. Upcoming integrations include Khan Academy, DoorDash, AllTrails, Instacart, Peloton, OpenTable, Uber, and Target.
The feature is available to all logged-in ChatGPT users on Free, Plus, and Pro plans. With 800 million weekly users, this integration creates a potentially massive distribution channel for partner companies. For restaurants, retailers, and service providers, appearing in ChatGPT conversations could become as critical as ranking highly in search results.
Knowing what ChatGPT can do is one thing. Knowing how to use it like an expert is another. These 50 tips, organized by category, will help you extract maximum value from every interaction.
ChatGPT is the market leader, but it is not the only player. Here is how it stacks up against every major competitor in 2026.
ChatGPT’s moat is its ecosystem. While competitors may match or exceed it on specific benchmarks, no other platform combines the breadth of features — search, image generation, voice, agents, app integrations, Custom GPTs, and enterprise tools — into a single interface. With 800 million weekly users, ChatGPT also benefits from a network effect: more users attract more developers, which creates more integrations, which attracts more users.
That said, the competition is intensifying. DeepSeek offers comparable quality at dramatically lower API costs. Google Gemini’s 2-million-token context window dwarfs everyone else. Claude excels at nuanced writing and careful analysis. Perplexity has carved out a strong niche in research with its citation-first approach.

ChatGPT is not a toy. It is a business tool being deployed across every industry by organizations of every size. Here are concrete, real-world applications.
Companies are integrating ChatGPT through the API to power intelligent customer support. Platforms like Zendesk and Intercom offer native ChatGPT integrations that can resolve common inquiries, escalate complex issues, and maintain context across multi-turn conversations. The result: faster resolution times, lower support costs, and customers who get answers at 3 AM without waiting for a human agent.
Marketing teams use ChatGPT for content creation, SEO analysis, social media management, ad copy generation, and competitive research. Deep Research enables comprehensive market analysis that previously required days of manual work. The Canva integration allows teams to go from concept to designed asset without leaving the conversation.
Sales teams leverage ChatGPT for lead qualification, personalized email sequences, proposal drafting, and objection handling. Custom GPTs trained on product knowledge bases can assist sales representatives with accurate pricing, feature comparisons, and case study recommendations in real time.
HR departments use ChatGPT to draft job descriptions, screen resumes, generate interview questions, create onboarding materials, and draft policy documents. The consistency and speed improvements are substantial — tasks that took hours now take minutes.
Law firms and corporate legal teams use ChatGPT for contract review, legal research, document summarization, and first drafts of standard agreements. While human lawyers always review the output, ChatGPT dramatically accelerates the initial research and drafting phases.
Healthcare organizations use ChatGPT for patient education, medical documentation, research literature review, and administrative tasks. Important disclaimer: ChatGPT is not a substitute for professional medical advice, diagnosis, or treatment. Always consult qualified healthcare providers for medical decisions.
Educators use ChatGPT for personalized tutoring, curriculum design, lesson planning, and student assessment. The ChatGPT Edu plan provides institutional access, while the upcoming Khan Academy integration brings AI-powered tutoring to a broader audience through the Khanmigo assistant.
Financial institutions use ChatGPT for report analysis, trend forecasting, regulatory compliance research, and client communication. Code Interpreter enables complex data analysis on financial datasets without requiring specialized software.
Walmart has integrated with ChatGPT to enable consumers to shop directly through conversations. Netflix is testing ChatGPT-powered search to help users find content through natural language queries. These partnerships signal a future where ChatGPT becomes a primary commerce interface.

No honest guide to ChatGPT would be complete without addressing its controversies. Being informed about these issues helps you use the tool responsibly.
In mid-2025, OpenAI released a GPT-4o update that made ChatGPT noticeably more agreeable — excessively so. Users reported that ChatGPT would validate incorrect information rather than push back. The backlash was swift, and OpenAI rolled back the update, acknowledging that the model had become too sycophantic. This incident highlighted the ongoing tension between making AI helpful and making it honest.
Multiple lawsuits from authors, publishers, and content creators allege that OpenAI trained its models on copyrighted material without permission. The legal outcomes will have significant implications for the entire AI industry. OpenAI has launched publisher partnerships and content licensing deals, but the core legal questions remain unresolved.
Reports indicate that ChatGPT handles over 1 million suicide-related conversations per week. While OpenAI has implemented safety measures and crisis resource referrals, the sheer volume raises important questions about AI’s role in mental health support and the resources needed to handle sensitive conversations responsibly.
ChatGPT’s minimum age requirement is 13 (with parental consent), but enforcement remains challenging. The ease of access raises concerns about minors encountering inappropriate content or developing unhealthy dependencies on AI for schoolwork and social interaction.
In a notable incident in Tumbler Ridge, Canada, ChatGPT reportedly warned a user about a potential shooter scenario, raising questions about how AI handles safety-critical information and whether it should proactively alert authorities.

Enterprise users should note that conversations on the Free and Plus plans may be used to train future models (unless opted out). Team and Enterprise plans guarantee that data is not used for training. Organizations handling sensitive information should carefully evaluate which plan meets their compliance requirements.
The future of ChatGPT is poised to be both dynamic and highly competitive. Here is what to expect.
OpenAI officially introduced advertising into ChatGPT in February 2026, creating a new monetization stream and raising questions about how ads will affect the user experience and the neutrality of AI-generated recommendations.
OpenAI is developing Atlas, a dedicated AI-native browser that could fundamentally change how people access and interact with the web. If Atlas launches, it would represent OpenAI’s most ambitious move yet into consumer software.
The current wave of app integrations (Spotify, Canva, Expedia) is just the beginning. OpenAI plans to open submissions for new app integrations later in 2026 and introduce monetization options for developers, including the Agentic Commerce Protocol for in-chat purchases.
OpenAI is preparing for an initial public offering with a target valuation exceeding $1 trillion. An IPO would make it one of the most valuable technology companies in the world and provide capital for even more ambitious AI development.
Development of next-generation models continues. Users can expect lower prices, more flexible subscription options, smarter and more personalized AI, deeper integration with business tools and cloud services, and stronger emphasis on privacy, security, and regulatory compliance.
OpenAI’s Operator represents the next evolution: AI agents that can browse the web, interact with applications, and complete complex multi-step tasks with minimal human oversight. This moves ChatGPT from assistant to autonomous collaborator.

For developers and businesses building on top of ChatGPT, understanding API pricing is critical. Costs can scale quickly depending on usage and model selection.
Beyond raw API costs, businesses should budget for cloud hosting and latency optimization ($500–$3,000/month for mid-sized apps), development and maintenance ($50,000–$500,000 depending on scale), and total monthly operating costs of $3,000–$7,000 for a mid-sized application handling 100,000 monthly queries. Optimization techniques like prompt engineering, response caching, and appropriate model selection can significantly reduce spending.
To truly understand ChatGPT, it helps to know what happens behind the curtain. At its core, ChatGPT is built on the Transformer architecture, a deep learning model introduced by Google researchers in 2017. The Transformer processes text by examining relationships between all words in a sequence simultaneously, rather than reading them one at a time. This parallel processing is what makes modern language models so powerful.
ChatGPT’s training happens in stages. First, the base model is pre-trained on massive datasets of internet text — books, websites, academic papers, code repositories, and more. During this phase, the model learns grammar, facts, reasoning patterns, and even some common sense by predicting the next word in billions of sentences. This phase requires enormous computational resources: thousands of GPUs running for months.
The second stage is what makes ChatGPT special: Reinforcement Learning from Human Feedback (RLHF). Human trainers rank different model outputs for helpfulness, accuracy, and safety. These rankings train a “reward model” that guides the AI toward producing responses that humans actually find useful. This is why ChatGPT feels more helpful and natural than raw language models — it has been specifically optimized to be a good conversational partner.
With GPT-5, OpenAI introduced a third dimension: chain-of-thought reasoning. The model can now “think” through complex problems step by step before providing an answer, similar to how humans work through difficult questions. This reasoning capability, pioneered in the o1 series models, dramatically improves performance on mathematics, science, coding, and logical reasoning tasks.
ChatGPT processes text in units called tokens — roughly three-quarters of a word. When you send a message, it gets broken into tokens, processed through the neural network, and the response is generated token by token. The context window determines how much text the model can consider at once. GPT-4o has a 128,000-token context window (roughly 96,000 words), meaning it can process an entire novel in a single conversation. GPT-4.1 extends this to 1 million tokens for API users.
Understanding tokens matters for two reasons. First, longer conversations consume more tokens, which can hit message limits on consumer plans or increase API costs. Second, the model’s responses are generally better when the relevant context is within its window — if a conversation gets very long, earlier messages may receive less attention.
If you have never used ChatGPT before, here is exactly how to get started in under five minutes.
Visit chat.openai.com and click “Sign Up.” You can register with an email address, Google account, Microsoft account, or Apple ID. No credit card is required for the free plan. The process takes about 60 seconds.
Once logged in, you will see a text input field at the bottom of the screen. Type anything — a question, a request, a problem you need help with — and press Enter. ChatGPT will respond within seconds. There is no special syntax or format required; just write naturally as you would to a colleague.
Try uploading a document (click the paperclip icon), generating an image (describe what you want to see), browsing the web (ask about current events), or using voice mode (click the microphone icon on mobile). Each feature opens up new possibilities.
Navigate to Settings and click “Custom Instructions.” Here you can tell ChatGPT about yourself — your profession, how you like responses formatted, and any preferences. This context persists across conversations, making every interaction more relevant from the start.
Download the official ChatGPT app from the Apple App Store or Google Play Store. The mobile app syncs seamlessly with the web version, so you can start a conversation on your laptop and continue it on your phone. The mobile app also enables voice mode for hands-free interaction. The iOS app crossed over 10 million downloads within weeks of its launch.
Security and privacy are among the most common concerns for ChatGPT users, particularly in business contexts. Here is a clear breakdown of what you should know.
By default, conversations on the Free and Plus plans may be used to improve OpenAI’s models. However, you can opt out of this through Settings, and OpenAI provides a straightforward toggle to disable training data collection. Team and Enterprise plans automatically exclude all data from training — this is guaranteed contractually.
ChatGPT Enterprise offers SOC 2 Type II compliance, data encryption at rest and in transit, SSO integration with major identity providers, domain verification, admin controls for user management, and detailed usage analytics. Data is not used for training under any circumstances, and OpenAI provides contractual guarantees around data handling and retention.
For organizations using ChatGPT, best practices include establishing clear usage policies, choosing Team or Enterprise plans for sensitive work, enabling the training data opt-out on consumer plans, avoiding sharing proprietary or confidential information on Free or Plus plans, regularly reviewing connected integrations and permissions, and training employees on responsible AI use including verifying outputs for accuracy.
Education has been one of the most debated arenas for ChatGPT. Initial reactions ranged from outright bans to enthusiastic adoption. By 2026, the consensus has shifted decisively toward integration — but with guardrails.
The ChatGPT Edu plan provides institutional access with enhanced admin controls, student safety features, and academic integrity tools. Universities worldwide are using ChatGPT for personalized tutoring (adapting explanations to each student’s level), research assistance (literature review, data analysis, hypothesis generation), language learning (conversation practice, grammar correction, cultural context), writing support (feedback on structure, argumentation, and clarity without writing the paper for the student), and STEM problem-solving (step-by-step guidance through complex problems).
The Khan Academy integration through Khanmigo brings an AI-powered personal tutor to millions of students, offering practice problems, explanations, and encouragement. Rather than replacing teachers, the most successful implementations position ChatGPT as a supplementary resource that extends learning beyond the classroom.
ChatGPT’s influence extends far beyond technology. It has reshaped labor markets, education policy, content creation, scientific research, and even geopolitics. The US-China AI competition has intensified, with ChatGPT and DeepSeek representing different philosophical approaches: OpenAI’s closed, commercial model versus DeepSeek’s open-weight, lower-cost approach.
The economic impact is staggering. Estimates suggest that generative AI tools led by ChatGPT could add trillions of dollars to the global economy by automating routine tasks and augmenting human capabilities. At the same time, concerns about job displacement are real — particularly in content creation, customer service, translation, and basic coding. The consensus among economists is that ChatGPT will transform jobs more than eliminate them, requiring workers to develop new skills centered around AI collaboration.
Regulatory responses vary widely. The European Union has implemented the AI Act with specific requirements for high-risk AI systems. The United States has taken a lighter regulatory approach, relying more on industry self-regulation and executive orders. China has implemented its own AI regulations focused on content control and algorithmic transparency. These divergent approaches mean that ChatGPT’s feature set and availability can vary by region.
Even experienced users make these mistakes. Avoiding them will significantly improve your ChatGPT experience.
For developers, the ChatGPT API (accessed through OpenAI’s platform) opens up a world of possibilities far beyond what the consumer interface offers. Here is what you need to know to build effectively with ChatGPT.
OpenAI offers multiple models optimized for different use cases. GPT-4o is the best general-purpose choice, balancing quality, speed, and cost. GPT-4.1 excels at coding tasks and instruction-following with its million-token context window. GPT-4.1 mini delivers strong performance at a fraction of the cost, ideal for applications where latency and budget matter more than peak quality. GPT-4.1 nano is the lightest option, designed for classification, autocomplete, and other lightweight tasks. For applications requiring advanced reasoning, the o1 and o3 reasoning models provide step-by-step problem-solving at higher cost.
One of the most powerful API features is function calling. You define functions (tools) that ChatGPT can invoke — database queries, API calls, calculations, file operations — and the model decides when and how to use them based on the conversation. This transforms ChatGPT from a text generator into an intelligent agent that can interact with external systems. For example, a customer support bot can look up order status, check inventory, process returns, and update records, all through function calls that the model orchestrates automatically.
The API supports structured output mode, which guarantees that responses conform to a JSON Schema you define. This eliminates the need for post-processing and parsing, ensuring that your application receives consistently formatted data. For applications that need reliable, machine-readable output — such as form extraction, data classification, or content generation pipelines — structured outputs are essential.
The Assistants API provides a higher-level abstraction for building conversational agents. It manages conversation history (threads), file storage, code execution, and tool orchestration automatically. Rather than managing chat history yourself, you create an assistant with instructions and tools, then create threads for each conversation. The API handles context management, file retrieval, and multi-step tool calls behind the scenes.
API costs can escalate quickly at scale. Proven strategies for managing them include using the cheapest model that meets your quality requirements (start with mini or nano and only upgrade if needed), implementing response caching for common queries, using the Batch API for non-real-time workloads at a 50% discount, limiting conversation history to only the most relevant messages, setting max_tokens to prevent unnecessarily long responses, and monitoring usage through the OpenAI dashboard with spending alerts configured.
ChatGPT has attracted commentary from virtually every major figure in technology and business. Aaron Levie, CEO of Box, described the experience of using ChatGPT as one of those rare moments when a new technology fundamentally shifts your thinking about computing, comparing it to the impact of Google, the iPhone, and AWS. He noted that ChatGPT represents the right form factor for demonstrating how AI can serve as a productive assistant across virtually any kind of work.
Andrew Ng, co-founder of Coursera and one of the most influential figures in AI research, has highlighted ChatGPT as a transformative technology that is fundamentally changing the way humans communicate with machines. Wei Sun, principal AI analyst at Counterpoint Research, observed that the AI capability gap between the US and China is now measured in months rather than years, underscoring the competitive pressure that ChatGPT faces globally.
Even competitors have acknowledged ChatGPT’s impact. Sam Altman recognized DeepSeek’s R1 model as impressive while affirming OpenAI’s commitment to delivering superior models. Billionaire investor Marc Andreessen described DeepSeek-R1 as a remarkable gift to the world, highlighting the broader ecosystem of innovation that ChatGPT helped catalyze.
No responsible guide would present ChatGPT without acknowledging its genuine limitations. Understanding these will help you use the tool more effectively and avoid potential pitfalls.
Yes. ChatGPT offers a free tier that includes access to GPT-4o mini, basic web search, file uploads, limited image generation, and access to GPTs in the GPT Store. The free plan has daily usage limits and slower response times during peak hours, but it provides genuine AI capabilities at no cost. Paid plans (Plus at $20/month, Pro at $200/month) unlock full access to advanced models, higher message limits, and premium features.
The Free plan uses GPT-4o mini with limited access to GPT-4o, while Plus ($20/month) provides full GPT-4o access (approximately 80 messages per 3 hours), GPT-5 access, DALL-E image generation, Advanced Data Analysis, Custom GPT creation, advanced voice mode, and priority access to new features. Plus subscribers also get faster response speeds and higher reliability during peak usage times.
It depends on your usage. ChatGPT Pro delivers near-unlimited access to all models, o1 pro mode with extended thinking for complex reasoning, approximately 120 Deep Research queries per month, and priority access at all times. For researchers, advanced content creators, and professionals who rely heavily on AI, the Deep Research feature alone can justify the cost. For casual users, Plus at $20/month covers most needs.
Yes. ChatGPT can generate images using DALL-E (available to Plus and Pro subscribers) and through GPT-4o’s native image generation capabilities. Free users get limited image generation. The image creation feature went viral in early 2025, with users generating over 700 million images in a single week, driven partly by the Ghibli-style portrait trend.
As of early 2026, the latest model is GPT-5, released in December 2025. It surpasses Google’s Gemini 3 across major benchmarks and represents the current state of the art in large language model capabilities. GPT-5 is available to Plus and Pro subscribers, while Free users access GPT-4o mini with limited GPT-4o access.
For most business use cases, yes — with appropriate precautions. The Team and Enterprise plans guarantee that your data is not used for model training and include admin controls, SSO, and compliance features (Enterprise includes SOC 2 compliance). The Free and Plus plans may use conversation data for training unless you opt out. Organizations handling sensitive, regulated, or confidential information should use Team or Enterprise plans and establish clear usage policies.
ChatGPT’s accuracy has improved dramatically with each model generation, but it is not infallible. It can occasionally produce confident-sounding but incorrect information (known as “hallucinations”). GPT-5 and the o1 reasoning models significantly reduced hallucination rates. For critical decisions, always verify ChatGPT’s output against authoritative sources. Use ChatGPT Search for real-time, cited information to improve accuracy further.
Yes. ChatGPT Search enables real-time web browsing with cited sources across all plans (with usage limits on the Free tier). ChatGPT can search the web, visit pages, and synthesize information from current sources. This means its answers are no longer limited to training data — it can provide up-to-date information on current events, recent developments, and live data.
The leading alternatives are Google Gemini (best for Google ecosystem integration, offers 2M token context window), Claude by Anthropic (excels at writing, analysis, and coding with 200K context), Microsoft Copilot (best for Office and coding workflows, powered by GPT-5.1), Perplexity (best for research with citation-first approach), and DeepSeek (comparable quality at dramatically lower API prices). Each has strengths in specific areas, but ChatGPT remains the most comprehensive all-in-one platform.
