From 573de7e51a481fae8582c8f01e2579ca054b1d41 Mon Sep 17 00:00:00 2001 From: chenhaonan Date: Mon, 5 Oct 2026 19:09:11 +0800 Subject: [PATCH 01/26] fix(providers): align ten vendor packages with their upstream counterparts What: fixes the differences that a package-by-package comparison against the pinned upstream sources found in OpenAI, Azure, Anthropic, Amazon Bedrock, Google, Google Vertex, Mistral, Cohere, xAI and the OpenAI-compatible package. The changes are in request building (option names and validation, schema handling, cache and beta merging, tool conversion), response mapping (usage, provider metadata keys, citations and sources, reasoning) and stream handling (error parts, raw chunks, finish data). Examples: - Bedrock percent-encodes the model id in the URL, writes metadata under both `amazonBedrock` and the legacy `bedrock` key, and applies upstream's capability rules to sampling settings and reasoning. - OpenAI embeddings request `encoding_format: "float"` and no longer decode base64 vectors; the Responses log-probability include follows upstream's condition. - Google no longer invents `response.model_id`; the call layer supplies the default, as upstream does. - Anthropic emits citation sources, forwards a mid-stream `error` event as an error part without a synthetic finish, and falls back to a JSON tool for structured output on models without native support. - Vertex accumulates partial function-call arguments; Vertex Anthropic uses the `googleVertex` namespace and never Express mode; Vertex transcription sends its credentials to the Speech-to-Text host (they were dropped before, so every such request went out unauthenticated). - xAI Responses returns image generation calls and results. - Each package sends its own `user-agent` suffix. Mistral has no `transform_request_body` setting. The deprecated `text_embedding` and `text_embedding_model` aliases are not carried over. Why: the direction is that Rust behaves as the AI SDK does, with upstream as the reference. Of 106 severe findings, 94 are fixed here; the 12 left need new model kinds, shared type changes or Google default credentials, and are listed with reasons in the pull request description.

These tests replay values taken from recordings, so their assertions are adjusted rather than the tests removed. - Removed tests that pinned behaviour Rust no longer has: top-level `cached_tokens` usage for two preset rows, a synthetic error finish after a mid-stream Anthropic error, a Responses stream that ends itself after an error event, two OpenAI embedding replays whose recordings hold base64 vectors, and a Bedrock stream replay over recordings that stored the binary event stream as text. Why: these tests asserted the old behaviour. No cassette or fixture is changed; the recordings that can no longer be replayed are listed in the pull request description.

Each builds the provider through its public factory with an in-process transport, calls the model, and asserts the request that was sent and the parts that came back. Per model kind there is at most one test each for generate, stream, tool call and error. Every test names the upstream test it comes from. Why: Azure and Vertex had no replay test at all, and the alignment needed something that exercises it. This is a selection, not a case-by-case port. The Vertex transcription test is the one that showed requests went out without credentials. One test is ignored with its reason: `CallOptions::tool_choice` is not optional, so `tool_choice: "auto"` is always sent where upstream omits it.

Groq and DeepSeek return the raw response body again. Mistral takes the tool message name from the tool result only. Bedrock has one request builder. OpenAI and Azure lose the unused request-body transform slot. Two end-to-end tests assert what the upstream tests assert: the full OpenAI stream sequence, and native structured output selected by the model id the upstream test uses. Why: an independent review found a crash, two dropped fields, one finding marked fixed that was not, a second code path, and two weakened tests.

Azure speech transcription with its own route and endpoint. Vertex and Vertex Anthropic application default credentials with the upstream auth options. A Gemini transcription model on Vertex. OpenAI Responses provider tools with their typed factories, request mapping and response and stream events. The Responses conversion returns an error where it could panic. One test per new feature is selected from the upstream test files. Why: these were listed as open differences from upstream; the owner's decision is to close them in this pull request rather than carry them.

a Google request-body difference is fixed. In-file test modules and test functions that earlier merge resolutions had restored are removed. Test files ported from upstream test suites are kept. Why: tool choice is optional now and the vendors omit it when unset, as upstream does. Hand-written tests that pin Rust-only behaviour are deleted in this project, and the branches below had already deleted these.

The Google end-to-end test no longer expects a default tool config. docs/api/providers.md is regenerated. Why: the last merge took the lower branch's copy of the regression test, which asserts the pre-alignment behaviour, and the generated provider list was stale after the new models were added.

Anthropic document citations are emitted as sources as far as the source type can carry them. Bedrock no longer returns a response body upstream does not return. A DeepSeek stream error event is reported as upstream reports it. The hand-written provider trait test is deleted. Why: an independent audit found that upstream-ported coverage had been removed together with hand-written tests, and listed these differences.

Removes the GenerateResponse and StreamResponse aliases. The Bedrock e2e test regains the upstream toolChoice input and assertion. Why: review of this branch against the pinned vendor packages.

Bedrock gains the S3 supported-url entry and sends an empty tool-use input as {}; its temperature warning matches upstream. The migrated Bedrock image and embedding tests mount the percent-encoded model path the model now requests. Why: the gate showed sixteen failures after the merges; in each case the pinned upstream behaviour decides.

28 upstream test cases ported. The shared media_type_to_extension now maps mpeg, mp4, x-wav and opus as upstream does. Why: the upstream mistral package has both model families and Rust did not; the user ruled that the missing model families are ported now.

Vertex gains speech() over the same implementation and its Gemini transcription reuses the shared options, offset parser and live loop (about 200 lines fewer). A peer close after the audio ended finishes the stream with the accumulated text as upstream does. 54 upstream test cases ported. Why: the upstream google package has both model families and Rust did not; the user ruled that the missing model families are ported now. Not ported: speech translation (no core type) and Vertex chirp text-to-speech.

Why: upstream has these in the ai and provider packages and Rust did not; the user ruled that the missing model families are ported now. Not ported: string aliases in the custom provider tables (Rust has no global default provider) and a user-facing evaluate().

Why: the upstream xai package has these model families and Rust did not; the user ruled that the missing model families are ported now.

the Google speech model takes its option namespace from the constructor (Google or Vertex) and spells the namespace through the options constants.

That is upstream's `serializeToolCallArguments` (@ai-sdk/openai 4.0.49 and later), not a loss of data: OpenAI function arguments are always objects. A comment and a test now say so. Why: the behaviour looked like a fidelity bug; it was kept on purpose to stay with upstream.
