DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.223

Gateway model discovery accepts model ids that merely contain claude or anthropic

You'll notice
Useful3 Signal0
Model Discovery

Gateways whose model ids carry a vendor prefix now show up instead of an empty model list.

ANTHROPIC_BASE_URL
What

Gateways that expose vendor-prefixed model ids no longer come back with an empty model list.

Details
  • The filter over the gateway model list changed from an anchored-at-start match to an unanchored one, so ids such as .../anthropic.claude-... now survive.
  • Previously discovery gave up with "[gatewayDiscovery] 0 usable models after filter".
  • Discovery requires ANTHROPIC_BASE_URL plus an auth token or header.
Evidence

[gatewayDiscovery] 0 usable models after filter

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
