From 56484e49cd330def21d97eaa27adedb0af24a344 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 12 Oct 2026 09:34:07 +0000 Subject: [PATCH] feat(providers): the remaining upstream model kinds, ported from the upstream packages - xAI speech, transcription and video models. - Google and Mistral speech and transcription models. - Groq transcription model. - customProvider, ported from upstream. - New models respect the provider boundary rules. OpenAI Chat replay of non-object tool input is pinned to upstream, and the ported Mistral tests name their pinned upstream source.
