# xAI — Grok 4.6 > 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, xAI'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/grok-4-6 - xAI's page: https://forck.live/company/xai - Every model: https://forck.live/models - Catalogue: https://forck.live/llms.txt ## Model - Name: Grok 4.6 - Company: xAI (x.ai) - Launch post: Introducing Grok 4.6 — https://forck.live/items/4347-introducing-grok-4-6 - Announced: 2026-08-12 - Launch source: https://x.ai/news/grok-4-6 - Launch chosen by: a person, pinned in the model registry - Released (per models.dev): 2026-08-12 - Listed (per OpenRouter): 2026-08-12 - Open weights: no - Posts about it: 5 - Outlets named under its posts: 2 - OpenRouter id: x-ai/grok-4.6 — https://openrouter.ai/x-ai/grok-4.6 - Context window: 500k context window — from https://forck.live/items/4491-grok-4-6-on-microsoft-foundry - Price: $2 per million input tokens and $6 per million output tokens — from https://forck.live/items/4347-introducing-grok-4-6 ## Posts about it _xAI's own posts whose title names Grok 4.6, 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. ### xAI — Grok 4.6 on Microsoft Foundry - Company: xAI (x.ai) - Announced: 2026-08-26 - Category: availability-change - Coverage: not counted - Announcement: yes - Group: announcements - Source: https://x.ai/news/grok-4-6-microsoft-foundry - Record: https://forck.live/items/4491-grok-4-6-on-microsoft-foundry - Subject: Grok xAI announces that Grok 4.6 is now available on Microsoft Foundry, offering a 500k context window and configurable reasoning efforts. ### xAI — Grok 4.6 on Google Enterprise Agent Platform - Company: xAI (x.ai) - Announced: 2026-08-21 - Category: availability-change - Coverage: not counted - Announcement: yes - Group: announcements - Source: https://x.ai/news/grok-4-6-vertex-ai - Record: https://forck.live/items/4343-grok-4-6-on-google-enterprise-agent-platform - Subject: Grok xAI announces that Grok 4.6 is now available on Google Enterprise Agent Platform via Model Garden, with a 500k context window, configurable reasoning efforts, and per-token pricing for input, cached input, and output. ### xAI — Grok 4.6 on Amazon Bedrock - Company: xAI (x.ai) - Announced: 2026-08-19 - Category: availability-change - Coverage: not counted - Announcement: yes - Group: announcements - Source: https://x.ai/news/grok-4-6-amazon-bedrock - Record: https://forck.live/items/4344-grok-4-6-on-amazon-bedrock - Subject: Grok Grok 4.6 is now generally available on Amazon Bedrock, with a 500k context window and configurable reasoning efforts, at the stated pricing per million tokens. ### xAI — Grok 4.6 in GitHub Copilot - Company: xAI (x.ai) - Announced: 2026-08-14 - Category: availability-change - Coverage: not counted - Announcement: yes - Group: announcements - Source: https://x.ai/news/grok-4-6-github-copilot - Record: https://forck.live/items/4346-grok-4-6-in-github-copilot - Subject: Grok Grok 4.6 is now available in GitHub Copilot, with API pricing at $2 per million input tokens and $6 per million output tokens. ### xAI — Introducing Grok 4.6 - Company: xAI (x.ai) - Announced: 2026-08-12 - Category: model-update - Coverage: not counted - Announcement: yes - Group: models - Source: https://x.ai/news/grok-4-6 - Record: https://forck.live/items/4347-introducing-grok-4-6 - Subject: Grok xAI releases Grok 4.6, an update to Grok 4.5 focused on long-running agents, interactive and visual work, achieving frontier intelligence on several benchmarks, available in Cursor, Grok Build, API, and partners, with pricing starting at $2 per million input tokens and $6 per million output tokens. ## Who reported on it _Outlets this record can name and link, under the first-party post each one covered.
