Description

AnyLLM.get_supported_providers() lists registry rows that have no declared LLMProvider member (ovhcloud today), but LLMProvider(name) rejects them. Downstream code that builds a provider picker from get_supported_providers() and validates the choice with LLMProvider(...) offers those providers and then refuses them. That is what happens in Otari today: adding OVHcloud as a hosted provider fails with 'ovhcloud' is not a known provider implementation.

This PR makes LLMProvider accept every name get_supported_providers() returns, rather than adding an OVHCLOUD member:

  • LLMProvider._missing_ resolves any PROVIDER_REGISTRY row to a member (LLMProvider("ovhcloud") gives <LLMProvider.OVHCLOUD: 'ovhcloud'>). Members are cached, so identity, hashing, equality with the plain string, pickling and deepcopy behave like declared members. A row that is removed from the registry stops resolving.
  • Iterating LLMProvider still lists declared members only. The enum drives the test matrix, and a registry-only row has no package or extra to test, so get_registry_provider_names(), get_supported_providers() and the matrix are unchanged.
  • resolve_provider_key, get_provider_enum and split_model_provider now return a member for registry-only rows too, instead of a bare string or an error. resolve_provider_key keeps its str | LLMProvider signature.
  • LLMProvider.from_string's error lists every supported provider, not just the enum, matching get_provider_enum and create.
  • CONTRIBUTING §2a documents that LLMProvider("examplegw") resolves a new row. A new row still needs no declared member, so §2a's policy is unchanged.

Rows that have a declared member are unaffected.

Summary by CodeRabbit

  • New Features
    • Registry-only provider names can now be used wherever a provider name is accepted, including through LLMProvider. Supported-provider listings and error messages include these providers.
  • Documentation
    • Clarified how registry-only providers are resolved and how supported-provider listings differ from enum iteration.

Walkthrough

Registry-only provider names now resolve to cached LLMProvider members. AnyLLM uses these members when resolving provider keys. Enum iteration still lists declared members only.

Changes

Registry-backed provider resolution

Layer / File(s) Summary
Dynamic enum member resolution
src/any_llm/constants.py, tests/unit/test_registry.py
LLMProvider resolves registered names as cached members. Unsupported-provider errors include registry names. Tests cover lookup, iteration, concurrency, and rejection cases.
Provider resolution integration
src/any_llm/any_llm.py, tests/unit/test_registry.py, tests/unit/providers/test_ovhcloud_provider.py, CONTRIBUTING.md
AnyLLM resolves provider keys through LLMProvider. Tests check registry-only provider resolution. The documentation describes lookup and iteration behaviour.

Comment thread src/any_llm/constants.py Outdated
AnyLLM.get_supported_providers() lists registry rows that have no
declared LLMProvider member (ovhcloud today), so callers that build a
picker from it and validate with LLMProvider(name) offer those rows and
then reject them. LLMProvider._missing_ now resolves any registry row to
a cached member. Iteration still covers declared members only, so the
enum-driven test matrix is unchanged.

Comment thread src/any_llm/constants.py Outdated
Two threads resolving the same registry-only name for the first time
could each store and return a different member. dict.setdefault makes
every caller return whichever member was stored first.
