ChatGPT
by
Conversational AI platform that combines large language models, multimodal inputs/outputs, app integrations and developer APIs to act as a general-purpose assistant.
See https://openai.com/chatgpt
Features
- Multimodal inputs and outputs: text, images, voice, and file uploads (PDFs, slides, code files).
- Advanced models and reasoning: model family includes GPT-4o and subsequent reasoning-focused models (o3, o4-mini, etc.) that can call tools and chain reasoning steps.
- Apps ecosystem: in-chat apps and an Apps SDK (preview) that let developers embed interactive experiences inside conversations.
- Custom GPTs: end-user creatable GPTs with configurable behavior, tool access (Custom Actions), and selectable models.
- Memory and personalization: optional memory to remember user preferences and project context across sessions.
- Projects & Canvas: organizational workspaces for multi-session tasks, file collaboration, and visual co-editing.
- Web & research tools: integrated web search and deep research modes to retrieve and synthesize current information with citations.
- Agentic capabilities & developer tools: AgentKit and MCP-based integrations allow building agents that use tools, APIs, and external data.
- Code execution & data analysis: secure runtime to run Python-like code for data analysis, visualization, and file-processing tasks.
- Image generation & video (Sora): image generation models and video-generation capabilities exposed via API (Sora integrations announced).
- Scheduling & automation: scheduled tasks and proactive reminders for Plus/Pro/Business tiers in some releases.
Superpowers
ChatGPT is useful for people and teams who need a conversational assistant that can:
- Turn vague goals into concrete deliverables (e.g., research reports, slide decks, email campaigns).
- Blend conversational guidance with direct tool use (running code, searching the web, editing files) without switching contexts.
- Rapidly prototype assistant-driven workflows using Custom GPTs and the Apps SDK.
- Provide multimodal help (explain a screenshot, summarize a PDF, walk through data visualizations).
Who benefits most:
- Product teams and PMs who want instant prototypes and research summaries.
- Knowledge workers who need long-form synthesis and follow-up automation.
- Developers building conversational experiences or embedding AI-driven features in apps.
Practical usage examples
- Research brief: upload a set of papers (PDFs) and ask ChatGPT to synthesize key findings, produce an executive summary, and output a slide outline.
- Data task: upload a CSV, ask ChatGPT to run analyses (trend detection, simple ML model guidance), and return charts + annotated code snippets.
- Custom assistant: build a Custom GPT for customer support that includes a knowledge base, a set of canned actions (ticket creation), and a recommended model.
Pricing
- Free tier: basic access to ChatGPT with some model and feature limitations.
- Plus / Pro / Business tiers: paid subscriptions that unlock better models, higher usage limits, faster response times, and access to Custom GPTs/Projects/Apps features.
- API / enterprise pricing: separate metered API billing for developers and enterprise plans with SLAs, advanced controls, and privacy options.
Privacy & safety notes
- Apps and integrations must disclose what user data they access; user consent is required when connecting third-party apps.
- Memory is optional and user-controllable; users can view/edit/delete saved memories.
- Enterprise offerings include additional administrative controls, data retention and privacy assurances.
- Developers must follow OpenAI usage policies when building apps or Custom GPTs.
Notable timeline & changes (2024–2025)
- Continued rollout of multimodal features, voice and image understanding across platforms.
- Introduction of Apps SDK and expanded App ecosystem (2025), enabling richer in-chat experiences.
- New reasoning-focused models (o3, o4-mini) and ongoing improvements to GPT-4o family.
- Expanded developer tooling (AgentKit, Codex updates) and API model options for cost/latency tradeoffs.
