Requesting changes: this breaks all three operations the Portkey provider supports. Verified locally against portkey-ai==2.3.4 with a mocked HTTP transport, on the PR rebased onto current main.
The provider keeps BaseOpenAIProvider's conversion layer, which dispatches on isinstance(response, openai...ChatCompletion). AsyncPortkey returns its own pydantic models, and for streams it returns models from a private vendored copy of the OpenAI SDK (portkey_ai._vendor.openai, pinned at 2.30.0 while any-llm resolves 3.0.0). Neither is an instance of the openai classes the base checks, so:
- Non-streaming completion falls into the stream branch of
_convert_completion_response_async(src/any_llm/providers/openai/base.py:186) and returns an async generator. Iterating it raisesTypeError: 'async for' requires an object with __aiter__ method, got ChatCompletions. The same call returns a properChatCompletionon main. - Streaming raises
ValidationErroron the first chunk. list_modelsraisesValidationError, soSUPPORTS_LIST_MODELS = Trueno longer holds.
run-linter is red on four mypy errors from this diff. One of them, Incompatible types in assignment (expression has type "AsyncPortkey", variable has type "AsyncOpenAI") at src/any_llm/providers/portkey/portkey.py:46, is the type checker naming this problem. (The fifth error in that run was the unrelated httpx2 one, since fixed by #1320.)
The new test monkeypatches AsyncPortkey away and asserts only the constructor kwargs, so it passes on broken code, and codecov/patch passes with it. 2254 unit tests are green on a fully broken provider, which is why this needs integration tests before merge; portkey is in the CI integration matrix.
On design: every other native-SDK provider here (groq/groq.py:46, xai/xai.py:52, cohere, together) subclasses AnyLLM and owns its conversion functions. Taking a native SDK means taking ownership of that layer.
Worth settling before more work goes in: portkey_ai is itself a thin wrapper over its vendored OpenAI client, so the gain over main is Portkey routing knobs as constructor kwargs instead of default_headers entries. The costs are a second copy of the OpenAI SDK in the all extra, version skew affecting Portkey traffic only, and a permanent shim against a private _vendor namespace. Closing #524 as "the OpenAI client is the right client for a proxy gateway" is a defensible answer.
Happy to share a working fix (conversion shim plus three regression tests that fail without it) if that is useful.

Solid, well-scoped move to the native Portkey client. I drove the new code against a real AsyncPortkey with a mocked HTTP transport, and completions, streaming, XML reasoning, tool calls, usage details, model lists, moderation, and error mapping all behave correctly. Two things need work: the default request timeout is now unlimited (the old client used 5s connect / 600s read), and two of the three new tests build response types the SDK never returns, so they do not cover the real shapes. Please also note that no CI job has run on this branch yet, and Portkey is in the integration matrix, so the run-integration-tests label is worth applying.

[major] Requests now go out with no timeout at all. Portkey's SDK pops timeout out of the call kwargs and passes timeout=None to its inner OpenAI client, and None means "no limit" in httpx. The old AsyncOpenAI client sent connect=5.0, read=600; AsyncPortkey sends connect=None, read=None, write=None, pool=None. A stalled gateway call now blocks forever instead of failing after 10 minutes. Client options do not help: AsyncPortkey(request_timeout=60) still yields an all-None timeout, because the per-call timeout=None wins. Set a default timeout in _convert_completion_params (and for the models.list call) to keep the old behaviour.

There was a problem hiding this comment.
[major] This helper says it builds "the actual vendored Pydantic model returned by portkey-ai", but that is not the type the SDK returns for two of the three paths. AsyncPortkey.chat.completions.create() without streaming returns portkey_ai.api_resources.types.chat_complete_type.ChatCompletions, and models.list() returns portkey_ai.api_resources.types.models_type.ModelList holding portkey_ai...models_type.Model. Only the streaming chunk is the vendored OpenAI type. So the two main regression tests pass without ever touching the real shapes, and a change in those Portkey types would not be caught. portkey_ai._vendor is also a private path that can move between releases. Building a real AsyncPortkey on an httpx.MockTransport covers all three paths and avoids private modules.

[minor] This change has no CI signal. Every workflow run on the branch is action_required, so unit tests, lint, and mypy never ran, and the description says pre-commit did not complete. Portkey is in the integration matrix and the client that talks to the gateway changed, so please apply the run-integration-tests label before merge.

[minor] The request on the wire changed. Portkey's client sends Authorization: Bearer OPENAI_API_KEY (a literal placeholder) and puts the real key in the x-portkey-api-key header, where the old client sent the key as the bearer token. That is correct for api.portkey.ai, but a user who points PORTKEY_API_BASE at a gateway expecting a bearer token loses authentication. Please confirm this against a real endpoint.

[minor] portkey-ai has no lower bound. The code needs portkey_ai.AsyncPortkey and the response shapes of a recent release, so a resolver that picks an old version would fail in a confusing way. Add a floor such as portkey-ai>=2.3.4, as other extras here do.

[minor] client: Any (with AsyncPortkey: Any above) removes all type checking from every self.client... call in the base class. Import the class directly inside the try block and declare client: AsyncPortkey behind TYPE_CHECKING, the way xai and mistral do, so mypy keeps checking those calls.

[nit] wrap_chunks_with_xml_reasoning is imported inside the method, but any_llm.providers.openai.xml_reasoning is already imported at the top of the file (line 8). There is no import cycle to avoid, so move this up with the other imports.

Pushed e3e597c to address the remaining native-SDK review feedback. The regression tests now exercise the real AsyncPortkey client with a mocked HTTP transport for completions, streaming, model listing, and moderation; the completion test also verifies the configured base URL and x-portkey-api-key header. The provider typing now matches AsyncPortkey. Validation: 61 focused tests passed, mypy passed, Ruff 0.15.20 format/check passed, and git diff --check passed. The full unit suite reached 2308 passed and 69 skipped; one existing failure remains in tests/unit/test_messages.py::test_message_response_preserves_beta_usage_speed_and_container_skills with the current Anthropic SDK, outside this diff. pre-commit could not initialize because GitHub hook download returned a network error. Please re-review e3e597c when convenient. |

Requesting changes. The conversion fixes work, but the approach needs a reset before another round.
Why a native SDK. The value of AsyncPortkey over AsyncOpenAI is that Portkey's types become the contract mypy checks this provider against. client: AsyncPortkey # type: ignore[assignment] cancels that: every method inherited from BaseOpenAIProvider is still checked against AsyncOpenAI, not the client this provider holds. No other provider ignores its client type. Subclass AnyLLM directly, as groq/groq.py does.
Typed converters. AnyLLM's converter signatures take Any. Hand that straight to a helper typed with the SDK class, as to_chat_completion(response: GroqChatCompletion) does in groq/utils.py:38, instead of branching on hasattr. One exception to pin with a test: create(stream=True) is annotated to yield the public ChatCompletionChunk but yields portkey_ai._vendor.openai...ChatCompletionChunk at runtime, which is not an instance of it.
Constructor. Other providers forward **kwargs because their SDKs reject unknown names. AsyncPortkey does not; it turns them into x-portkey-* headers, so timeout, max_retries, and default_headers are silently lost today. Rewriting kwargs by hand is also what lost the typing. request_timeout receives an httpx.Timeout, which Portkey sends as a header the gateway reads in milliseconds, so client_args={"timeout": 30} becomes a 30 ms gateway timeout. Passed directly, mypy rejects it: expected "int | None". Handle or reject each AsyncOpenAI-style kwarg explicitly, with a unit test for each.

Hi @mikemikimike, thank you for your work on this one! I would recommend taking some closer human inspection for these ones, AI really loves to bypass the mypy checks if they don't behave but the idea is that by using the provider sdks we can benefit from type checking. If there is an issue with the type checking with the portkey library, we then have the opportunity to file a bug report in the portkey sdk so that they can fix their sdk and then everyone benefits, not just any-llm! Thank you for all your contributions 🙏 |
