New models from Anthropic, OpenAI and Google reported to be launching soon

Three new models—Fable 5.5, GPT-6.1 Terra and Gemini 4 Flash—have successively been reported as being deployed or tested, and may launch soon. Fable 5.5 is said to have been deployed to enterprise customer environments such as JPMorgan Chase and Meta for early testing, and also appeared in the Azure model catalog marked as generally available. GPT-6.1 Terra appeared in a GitHub employee's Copilot configuration; Gemini 4 Flash is suspected to be in gray-scale testing, and is rumored to be close in capability to the flagship Gemini 4 Argon.
