Fiche publique

Vue d’ensemble

ChatGPT is OpenAI’s general-purpose conversational AI product. Since its public launch in November 2022, it has evolved from a text-based research preview into a multimodal and agentic platform spanning conversation, reasoning, web search, deep research, voice, image generation and understanding, file and data analysis, coding, projects, scheduled tasks, custom GPTs, plugins and connected applications. ChatGPT uses different OpenAI model families depending on plan, mode, task and rollout status. In 2026, GPT-5.6 became a major model family across ChatGPT, and GPT-6 Astra began a phased rollout in September 2026 for advanced coding, research, computer use and complex multi-step work.

Limites connues

Capabilities, model access, usage limits and tools vary by subscription plan, region, workspace policy, device and rollout status.ChatGPT can produce incorrect, incomplete or outdated information; source verification remains necessary for consequential or time-sensitive decisions.Connected apps and plugins are constrained by user authorization, provider permissions, workspace controls and the capabilities exposed by each integration.Agentic and computer-use features may require confirmations or additional safeguards before consequential external actions.Voice, video, screen-sharing and other multimodal capabilities vary by voice mode, client surface and account eligibility.Model behavior, memory and available reasoning effort can change as OpenAI updates the active product configuration.
Détail technique et structuré

Description technique

Structured AI assistant record for ChatGPT. The product is an orchestration layer over OpenAI model families and integrated tools rather than a single fixed model. Its runtime capabilities can include text and image input, image generation, web search, deep research, code execution and data analysis, file processing, memory and project context, voice interaction, scheduled tasks, plugins, connected apps and agentic computer-use workflows. Model selection, reasoning effort, tools and feature availability vary by plan, region, workspace policy, client surface and rollout state. Primary source anchor: https://chatgpt.com/.
