# OpenAI — GPT-5.1 > AI lab announcements, news reports and podcasts. forck.live follows what companies announce about their own products. Press may corroborate an official story; it never leads and never appears as an item of its own. A missing date stays missing. A title is the publisher's words — where a company does not publish in English, an English rendering is listed separately as `Title in English` and named as this site's translation, never as theirs. This file is the record of one model version: what the model registry states about it, OpenAI's launch post, the first-party posts this record holds about it, the outlets that reported on those posts, and other companies' announcements that it runs on their platforms. A model ranks nothing here and nothing is composed: each date names whose it is, and a field nothing states is `not stated` rather than missing. - This model's page: https://forck.live/models/gpt-5-1 - OpenAI's page: https://forck.live/company/openai - Every model: https://forck.live/models - Catalogue: https://forck.live/llms.txt ## Model - Name: GPT-5.1 - Company: OpenAI (openai.com) - Launch post: not held by this record - Announced: not stated - Launch source: not stated - Launch chosen by: not stated - Released (per models.dev): 2025-11-13 - Listed (per OpenRouter): 2025-11-13 - Open weights: no - Posts about it: 4 - Outlets named under its posts: 0 - Variant: GPT-5.1-Codex — https://forck.live/models/gpt-5-1-codex - OpenRouter id: openai/gpt-5.1 — https://openrouter.ai/openai/gpt-5.1 ## Posts about it _OpenAI's own posts whose title names GPT-5.1, and its launch post, in the record's order: dated newest first, undated last. The record reads the newest 50 first-party posts mentioning the model, every company's together, so a model mentioned more often than that lists the newest of them._ Every entry is one first-party announcement, and carries the same eight fields in this order before any others: Company · Announced · Category · Coverage · Announcement · Group · Source · Record `Source` is the company's own page the announcement was traced to and `Record` is this site's page for it. Both are safe to cite. `Coverage` is a number of outlets, or `not counted` — which means this record reached no count of its own, never that nobody wrote about it. `Category` is this tracker's own analysis, and is authoritative wherever it is stated. `not stated` means either that nothing has analysed the post yet or that the analysis placed it outside this taxonomy; neither is a verdict about the announcement. `Announcement` is whether the post is news of something the company did, rather than a how-to, a customer story, a changelog listing or a staffing note. `Group` is which of this record's groups the entry falls in, carried on the entry itself so it holds where the groups are headings and where they are not. One of: `models`, `covered`, `announcements`, `routine`. Anything after `Record` is held detail that only some announcements carry. ### OpenAI — How Tolan builds voice-first AI with GPT-5.1 - Company: OpenAI (openai.com) - Announced: 2026-01-07T10:00:00+00:00 - Category: not stated - Coverage: not counted - Announcement: no - Group: routine - Source: https://openai.com/index/tolan - Record: https://forck.live/items/319-how-tolan-builds-voice-first-ai-with-gpt-5-1 - Subject: GPT / ChatGPT / API Tolan built a voice-first AI companion using GPT-5.1, combining low-latency responses, real-time context reconstruction, and memory-driven personalities for natural conversations. ### OpenAI — Introducing GPT-5.1 for developers - Company: OpenAI (openai.com) - Announced: 2025-11-13 - Category: model-update - Coverage: not counted - Announcement: yes - Group: models - Source: https://openai.com/index/gpt-5-1-for-developers - Record: https://forck.live/items/384-introducing-gpt-5-1-for-developers - Subject: GPT / ChatGPT / API GPT-5.1 is now available in the API with faster adaptive reasoning, extended prompt caching, improved coding performance, and new apply_patch and shell tools. ### OpenAI — GPT-5.1: A smarter, more conversational ChatGPT - Company: OpenAI (openai.com) - Announced: 2025-11-12 - Category: model-update - Coverage: not counted - Announcement: yes - Group: models - Source: https://openai.com/index/gpt-5-1 - Record: https://forck.live/items/390-gpt-5-1-a-smarter-more-conversational-chatgpt - Subject: GPT / ChatGPT / API OpenAI is upgrading the GPT-5 series with warmer, more capable models and new customization options for ChatGPT's tone and style.
