公式の更新履歴を見る ↗Feature / gpt-5.2 / gpt-5.2-chat-latest / v1/responses / v1/chat/completions
Released GPT-5.2, the newest flagship model in the GPT-5 model family. GPT-5.2 shows improvements over the previous GPT-5.1 in: General intelligence Instruction following Accuracy and token efficiency Multimodality—especially vision Code generation—especially front-end UI creation Tool calling and context management in the API Spreadsheet understanding and creation. What's new in 5.2 is a new xhigh reasoning effort level, concise reasoning summaries, and new context management using compaction.
公式の更新履歴を見る ↗Feature / v1/responses/compact
Released client-side compaction. For long-running conversations with the Responses API, you can use the /responses/compact endpoint to shrink the context you send with each turn.
公式の更新履歴を見る ↗Feature / gpt-5.1-codex-max / v1/responses
Released gpt-5.1-codex-max to the Responses API. GPT-5.1-Codex is our most intelligent coding model optimized for long-horizon, agentic coding tasks. Read more here.
公式の更新履歴を見る ↗Feature / v1/realtime
Added support for DTMF key presses in the Realtime API. You can now receive DTMF events while using a Realtime sideband connection. See docs here for more information.
公式の更新履歴を見る ↗Feature
Released enhanced role-based access controls (RBAC). Role-based access control (RBAC) lets you decide who can do what across your organization and projects—both through the API and in the Dashboard.
公式の更新履歴を見る ↗Feature / gpt-5.1-codex / gpt-5.1-codex-mini / v1/responses
Released gpt-5.1-codex and gpt-5.1-codex-mini to the Responses API. GPT-5.1-Codex is a version of GPT-5.1 optimized for agentic coding tasks in Codex or similar environments. Read more here.
公式の更新履歴を見る ↗Feature
Released extended prompt cache retention. Extended prompt cache retention keeps cached prefixes active for longer, up to a maximum of 24 hours. Extended Prompt Caching works by offloading the key/value tensors to GPU-local storage when memory is full, significantly increasing the storage capacity available for caching.
公式の更新履歴を見る ↗Feature / gpt-5.1 / gpt-5.1-codex / gpt-5.1-chat-latest / gpt-5.1-codex-mini / v1/responses / v1/chat/completions
Released GPT-5.1, the newest flagship model in the GPT-5 model family. GPT-5.1 is trained to be especially proficient in: Steerability and faster responses when less thinking's required Code generation and coding use cases Agentic workflows Note that GPT-5.1 defaults to a new none reasoning setting for faster responses when less thinking's required—different from the previous medium default setting in GPT-5.
公式の更新履歴を見る ↗Feature / gpt-oss-safeguard-120b / gpt-oss-safeguard-20b
gpt-oss-safeguard-120b and gpt-oss-safeguard-20b are safety reasoning models built-upon gpt-oss. Read more here.
