From 13dd954593266ce94f4c38a65779530abb4fa3a1 Mon Sep 17 00:00:00 2001 From: Daniel Yudelevich <4537920+yudelevi@users.noreply.github.com> Date: Fri, 5 Jun 2026 02:07:02 -0700 Subject: [PATCH] Mark xAI models retiring on 2026-05-15 (#28788) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per https://docs.x.ai/developers/migration/may-15-retirement, xAI is retiring the following slugs on 2026-05-15 (auto-redirect to grok-4.3 with various reasoning efforts; callers continuing to use the old slugs will be billed at grok-4.3 pricing): grok-4-1-fast-reasoning{,-latest} -> grok-4.3 (low effort) grok-4-1-fast-non-reasoning{,-latest} -> grok-4.3 (none) grok-4-fast-reasoning -> grok-4.3 (low effort) grok-4-fast-non-reasoning -> grok-4.3 (none) grok-4-0709 -> grok-4.3 (low effort) grok-code-fast-1{,-0825} -> grok-build-0.1 grok-3 -> grok-4.3 (none) Only the direct xai/ slugs are tagged; third-party hosts (azure_ai, oci, vercel_ai_gateway, perplexity/xai) run their own schedules. The grok-3 retirement list explicitly names only the base grok-3 slug — the -mini / -fast / -beta / -latest variants are not listed, so they remain untouched. --- ...odel_prices_and_context_window_backup.json | 30 ++++++++++++------- model_prices_and_context_window.json | 30 ++++++++++++------- 2 files changed, 40 insertions(+), 20 deletions(-) diff --git a/litellm/model_prices_and_context_window_backup.json b/litellm/model_prices_and_context_window_backup.json index fbe6c097202..75547fe42d4 100644 --- a/litellm/model_prices_and_context_window_backup.json +++ b/litellm/model_prices_and_context_window_backup.json @@ -36004,7 +36004,8 @@ "supports_prompt_caching": true, "supports_response_schema": false, "supports_tool_choice": true, -
