From a0fe7e31c7a5dcdce78f21cbb6024cdc38320165 Mon Sep 17 00:00:00 2001 From: Dotta Date: Tue, 9 Jun 2026 18:12:03 +0000 Subject: [PATCH] Add Claude Fable 5 and Mythos 5 to the model selector Add the newly released claude-fable-5 (GA) and claude-mythos-5 (limited availability) models to the claude_local adapter model list, plus the Fable 5 Bedrock identifier. Opus 4.8 stays first so it remains the default selection; the new flagship models are offered but not defaulted. Models flow through the single claudeModels source, so they also appear in the ACPX combined list and are recognized by the ACPX Claude filter.
