This lookup was a fixed table and is now worked out in code. It can now:\n\n- filter models by which providers offer them\n\n- point a model alias, a short name for a model, at a different target for each provider, with a default\n\n- fall back to the target for Anthropic's own service when a provider does not offer the model\n\n**Why**\n\nThis changes how Claude Code picks the actual model behind a name depending on which provider you use.\n\n- Area: Models\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
