Custom model training services for developers. Winding down as OpenAI shifts focus toward 'reasoning' models and RAG-based architectures, significantly impacting the strategy for AI startups. Recommended replacement: Anyscale or Together AI.
Dashboard and API for running model evals. Deprecated June 3, 2026; goes read-only October 31, 2026, and shuts down November 30, 2026.
OpenAI's visual agent-building product for developers. Deprecated on June 3, 2026, with shutdown scheduled for November 30, 2026. ChatKit remains available. Recommended replacement: Agents SDK or ChatGPT Workspace Agents.
The final decommission of the GPT-3.5 architecture, including 1106 and turbo-instruct. Recommended replacement: gpt-5.4-mini.
The remaining second-generation base models used for fine-tuning and simple completions. Recommended replacement: gpt-5.4-mini or gpt-5-mini.
Programmatic access to the Sora 2 video models. Deprecated March 24, 2026; full shutdown scheduled for September 24, 2026.
A high-level API for building AI assistants. Deprecated in favor of the more flexible Responses and Conversations APIs. Recommended replacement: Responses API and Conversations API.
A standalone, Chromium-based AI browser for macOS featuring built-in memory and an autonomous 'Agent Mode.' Shuttered less than a year after launch as OpenAI pivoted to integrating cloud browsing, tabs, and agentic workflows directly into the core ChatGPT desktop application.
The CUA model behind Operator, exposed as a preview API. The preview snapshot is scheduled for shutdown on July 23, 2026.
Proactive daily briefings in ChatGPT Pro that researched overnight and surfaced personalized update cards. Launched in September 2025; OpenAI is sunsetting it and pointing users to scheduled tasks instead.
Side-by-side writing and coding workspace inside ChatGPT.
The third iteration of OpenAI's image generator. Retired to make way for the 'GPT Image' natively multimodal series. Recommended replacement: gpt-image-1 or gpt-image-1-mini.
The model that sparked the AI image generation trend. Retired alongside DALL-E 3. Recommended replacement: gpt-image-1-mini.
The preview version of the low-latency audio API. Recommended replacement: gpt-realtime-1.5.
A high-fidelity text-to-video platform. Abruptly shuttered following the collapse of a $1B Disney partnership and a strategic pivot to robotics/IPO prep. Recommended replacement: Google Veo or Kling.
Legacy GPT-4 and GPT-4 Turbo preview snapshots (including 0314, 1106-preview, and 0125-preview). Retired to streamline the API toward the GPT-5 series. Recommended replacement: gpt-5 or gpt-4.1.
Short-lived iterative models from the GPT-5 series, retired across ChatGPT and GPTs to consolidate on the 5.2 architecture. Recommended replacement: GPT-5.2 series.
The specific dynamic pointer for the latest ChatGPT-flavor of GPT-4o in the API. Recommended replacement: gpt-5.1-chat-latest.
The 'efficient' flagship that famously replaced GPT-4.5. While loved by developers for its logic, it was sunset in the ChatGPT interface less than a year later to force migration to the GPT-5 ecosystem. Recommended replacement: GPT-5.4.
The initial launch versions of the GPT-5 series, sunset after the 5.1 and 5.2 updates rendered them obsolete. Recommended replacement: GPT-5.2.
The 'Omni' model that powered ChatGPT. Deprecated to consolidate users onto the GPT-5 foundational series. Recommended replacement: GPT-5 series.
An efficiency-focused reasoning model. Retired from ChatGPT just four months after release. Recommended replacement: gpt-5.4-mini.
The first reasoning models from OpenAI. Sunset following the release of o3 and o4 series. Recommended replacement: o3 or o4-mini.
Research-preview browsing agent at operator.chatgpt.com. Folded into ChatGPT Agent in July 2025, and the standalone site was sunset weeks later.
A very short-lived preview that bridged the gap between GPT-4 and GPT-5. Recommended replacement: gpt-4.1.
The model that brought AI to the masses. It was the default free-tier engine for over two years before being fully replaced by 'mini' architecture models to save on compute. Recommended replacement: gpt-4.1-mini or gpt-5.4-mini.
A ChatGPT voice shown at the GPT-4o demo, paused within days after comparisons to Scarlett Johansson's Her voice sparked a public dispute.
Third-party tool integrations for ChatGPT. The beta was wound down in favor of GPTs and Actions, then fully shut down April 9, 2024.
The original web interface for DALL·E 2. OpenAI stopped accepting new customers and credit purchases on this date, directing all web users to DALL·E 3 within ChatGPT. Recommended replacement: ChatGPT (DALL·E 3).
Endpoint for editing text given an instruction. Deprecated in 2023 and shut down January 4, 2024.
Tool that claimed to detect AI-written text. Pulled less than six months later 'due to its low rate of accuracy'.
The specialized model series (including code-davinci-002) for natural language to code. Shut down with only 3 days' notice. Recommended replacement: gpt-4o.
The industry-standard toolkit for reinforcement learning. OpenAI ceased maintenance in 2021. Recommended replacement: Gymnasium.
AI products evolve quickly. Names change, models are replaced, APIs are deprecated, and documentation disappears. This project preserves a simple public record of what existed, when it launched, and when it ended.
