5 deployments dated September 7 to 13, 2026 are in The Deploy Log: 1 lead and 4 in Models and APIs, from 5 publishers. They include GPT-6 Astra from OpenAI, Claude Fable 5.1 from Anthropic, Gemini 3.8 Flash from Google, K2 Horizon from IFM and Muse Spark 1.3 from Meta. Every item sourced to the publisher's own page.
GPT-6 Astra, rolling out to the OpenAI API and through Microsoft Azure and Amazon Bedrock at $10 per million input tokens and $50 per million output, the same headline price as Anthropic's Claude Fable 5.1, which shipped the same week. Cache reads are priced separately, and Fast mode costs 2x.
Unchanged at $10 per million input and $50 per million output, with cache reads down to $0.25 per million, and Mythos 5.1 alongside it.
$0.75 per million input and $3.75 per million output until December 31, 2026, then $1.50 and $7.50 from January 1, 2027.
Open weights under Apache 2.0: 375B parameters, 23B active per token, a 512K context window, and a GPQA Diamond score of 87.3 in the model card's own table.
Two prices for the same model and the same 1M context window: $0.10 per million input on the contributor tier, where your inputs improve Meta's products, and $1.25 on the standard tier, where they do not.
