Source Intelligence

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.

Model ID Override Mapping (Enterprise)

What

Enterprise administrators can now map Anthropic model IDs to provider-specific model IDs (e.g., Bedrock inference profile ARNs) via managed settings.

Details
  • New modelOverrides setting in the configuration schema
  • Maps standard Anthropic model names (e.g., "claude-opus-4-6") to provider-specific identifiers
  • Reverse mapping is applied when resolving model families, so features that depend on knowing the model class (opus/sonnet/haiku) continue to work correctly
  • Typically set by enterprise administrators in managed settings files, not by end users
Evidence

Model override resolver — Wfq() and Dk1() at ~line 529379 (search for "Override mapping from Anthropic model ID")

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