Matching a model against that list used to compare only the model's name and its alias, ignoring upper and lower case. It now also:\n\n- Tries the part of the model id after the last `\/`, so an id with a provider prefix in front can still match.\n\n- Expands matches through the names and families in the model catalog.\n\nWhen Claude Code is not using Anthropic's own API, enforcing the list now picks the first usable entry from it.\n\n**Why**\n\nAn `availableModels` list written with plain model names now works for ids that a provider or gateway writes with a prefix such as a provider name and a slash.\n\n- Area: Models\n- Names: `availableModels`\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: org\n- Heads-up: no"}
