📝 WalkthroughWalkthroughChangesNative Files API support adds typed file handles, provider-specific file sources, upload and lifecycle activities, provider mappings, fail-closed capability checks, endpoint-specific errors, documentation, examples, and end-to-end tests. Native Files API
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk:🔵 Low · up to The PR’s file-source behavior is mergeable with explicit owner follow-up because the wire-test route still has bounded error-handling issues that can cause misleading success results or unhandled failures for unsupported providers.

Inline comments:
In `@examples/ts-react-chat/src/routes/index.tsx`:
- Around line 337-339: Update hasRenderablePart to count an image as renderable
only when its source contains a value, matching the guard in the image rendering
branch. Preserve visibility for other supported part types and keep the existing
<img> rendering behavior unchanged.
In `@examples/ts-react-media/src/lib/server-functions.ts`:
- Around line 115-139: The uploadInlineImageInputs flow in
examples/ts-react-media/src/lib/server-functions.ts must cache uploaded handles
per inline image, reuse fileSourceFromHandle(handle) on later requests, and
remove temporary uploads when a request fails. Update
examples/ts-react-media/src/components/ImageGenerator.tsx:185-186 to preserve
and pass the reusable handles, and update docs/advanced/files-api.md:92-110 to
document the reuse and failure-cleanup behavior.
In `@packages/ai-anthropic/src/adapters/files.ts`:
- Around line 71-76: Ensure the explicit apiKey argument remains authoritative
in every provider factory by spreading config before it: update
createAnthropicFiles in packages/ai-anthropic/src/adapters/files.ts (lines
71-76), the corresponding factory in packages/ai-gemini/src/adapters/files.ts
(lines 69-74), and the corresponding factory in
packages/ai-openai/src/adapters/files.ts (lines 72-77) to construct adapters
with config first and apiKey last.
In `@packages/ai-openai/tests/files-source.test.ts`:
- Around line 148-178: Update the foreign-provider file-handle test around chat
and the create mock to assert that the OpenAI client is never called. Keep the
existing RUN_ERROR and OpenAI-message assertions, and add a call-count
expectation on the mocked create function after consuming the stream.
In `@packages/ai/src/activities/chat/index.ts`:
- Around line 1339-1345: Validate file-source support in
runStructuredFinalization after structured-output middleware configuration and
immediately before each structured-output provider call, including
structuredOutputStream and structuredOutput. Reuse
assertMessagesFileSourceSupport(this.adapter, this.messages) so schema-only
requests fail closed for adapters without file-source support.
In `@packages/ai/src/activities/generateImage/index.ts`:
- Around line 285-288: Move the existing try block in the generation flow to
begin before assertPromptFileSourceSupport(adapter, rest.prompt), while keeping
the preflight validation inside that try. Ensure failures after
runGenerationStart are routed through the existing runGenerationError and
logger.errors handling.
In `@packages/ai/src/types.ts`:
- Around line 279-286: Update the documentation for ContentPartFileSource in the
multimodal content source specification to describe reference as a
provider-keyed record, rather than a singular issuing provider. Keep the
descriptions for data and url sources unchanged.
In `@packages/ai/src/utilities/tool-result.ts`:
- Line 14: The file-source validation must reject array references and only
accept a non-empty provider-to-reference record. Update the relevant type
guard/schema in tool-result handling to require !Array.isArray(reference) and
validate record values with Zod rather than Object.values() on untrusted input;
revise the nearby docstring to describe a non-empty reference record instead of
a string value.
In `@testing/e2e/src/routes/api.file-source-wire.ts`:
- Around line 25-29: Validate the file-source wire HTTP contract with Zod: in
testing/e2e/src/routes/api.file-source-wire.ts lines 25-29, parse provider,
handleProvider, and testId before adapter creation and return HTTP 400 for
invalid input; in testing/e2e/tests/file-source-wire.spec.ts lines 36, 54, 67,
82, and 93, replace response type assertions with the appropriate Zod result
schema parsing for each OpenAI, Anthropic, and Gemini success or rejection
response.
- Around line 71-76: Update the RUN_ERROR handling in the route’s
chunk-processing logic to assign runError for every chunk with type RUN_ERROR,
regardless of whether its message contains “file”; preserve the existing message
value for the failure response.

contents. Also move packages/ai-gemini/tests/files-adapter.test.ts beside
packages/ai-gemini/src/adapters/files.ts as a *.test.ts file; no test logic
changes are required.
In `@packages/ai-byteplus/tests/files-source.test.ts`:
- Around line 1-5: Move the BytePlus test from
packages/ai-byteplus/tests/files-source.test.ts to

In `@packages/ai-gemini/tests/files-source.test.ts`:
- Around line 1-4: Move the test file beside the tested GeminiTextAdapter source
under src/adapters, preserving its *.test.ts name and Vitest-based
implementation.
In `@packages/ai-openai/src/index.ts`:
- Around line 81-87: Add an adapters barrel at src/adapters/index.ts that
re-exports the OpenAI files adapter symbols, and add the corresponding
./adapters package export entry so `@tanstack/ai-openai/adapters` resolves to that
barrel while preserving the existing root exports.

- Around line 1-4: Move the test from the package-level test location to sit
beside the exercised OpenAITextAdapter source, using the adjacent
*.files-source.test.ts naming pattern under the adapters directory. Preserve its
existing Vitest implementation and assertions.
In `@packages/ai/tests/files-source.test.ts`:
- Around line 1-220: Move the tests alongside their source modules: relocate

Maintainer sweep: rebased onto main (force-with-lease). |
…+ `file` content source)
Add first-class support for provider Files / storage APIs so callers can
upload media once and reference it by a provider-issued handle instead of
re-sending base64 or a public URL each request.
- New tree-shakeable `files` adapter kind: openaiFiles(), anthropicFiles(),
geminiFiles(), falFiles() — each with upload(), plus get()/delete() where
the provider has a lifecycle API (fal is upload-only). Driven by the new
uploadFile()/getFile()/deleteFile() activity functions.
- New `{ type: 'file' }` arm on ContentPartSource. Adapters map it to the
provider's native reference: OpenAI (Responses) input_image/input_file
file_id, Anthropic file_id source (sends the files-api-2025-04-14 beta),
Gemini fileData.fileUri, fal storage URL. fileSourceFromHandle() builds
the source from an uploaded FileHandle.
- Runtime provider routing: a handle only routes to its issuing provider;
cross-provider handles and endpoints that require raw bytes (image edits,
Veo, Chat Completions images, Bedrock, Mistral, Grok, OpenRouter, Ollama)
throw a clear error instead of silently mis-mapping.

Bump the example's `nitro` to `latest` (3.0.260610-beta) — older Nitro rejected `@google/genai`'s resumable upload (explicit `Content-Length` on a Blob body) with "invalid content-length header", surfaced as "fetch failed".

…thread provider-literal handle types Post-review completion pass for the Files API PR (rebased onto main): - ai-byteplus (landed on main after this branch): file-source guards in text/image/video adapters + tests — a handle would previously have been sent to Ark as a URL. - Gemini Interactions video path: add the missing assertOwnFileSource guard (the sibling text-interactions adapter already had it) + tests. - openai-base Responses: new `supportsFileIdInput` gate (true only for OpenAI itself) so Grok/Bedrock/compatible subclasses reject file sources instead of inheriting the file_id mapping; chat-completions error copy no longer points non-OpenAI providers at openaiText. Tests for both. - Provider-literal handle types: FileHandle<TProvider>/FilesAdapter<TName> thread each adapter's name literal through uploadFile; getFile/deleteFile accept the handle itself, making cross-provider lifecycle calls compile errors. fileSourceFromHandle + FileHandle now also exported from the browser-safe @tanstack/ai/client entry. - Docs: fix broken openaiText import in multimodal-content.md, document the uploadFile/getFile/deleteFile dispatchers, correct the fal get/delete and explicit-key claims; kiira green. Skills: adapter-configuration §7 + chat-experience/media-generation notes. - Tests: gemini files-source mapping/rejection, OpenAI Responses document- arm behavior, toFileHandle normalizers (openai/gemini/fal), handle-object lifecycle dispatch, and an aimock e2e (file-source-wire) covering the round-trip + cross-provider rejection end-to-end. - Polish: unsupportedFileSourceError detail no longer contradicted by the generic tail, ollama uses this.name, fal expiresIn !== undefined, comment rot fixes; changeset updated (adds ai-byteplus patch). # Conflicts: # docs/config.json # packages/openai-base/src/adapters/responses-text.ts
…y preflight
Redesigns the `{ type: 'file' }` content source before it ships:
- The source now carries a per-provider reference record —
`{ type: 'file', reference: { openai: 'file-…', gemini: 'https://…' } }` —
instead of a single { value, provider } pair. Each adapter reads only its
own entry (`fileReferenceFor`), and a lookup miss throws naming the
providers that are present. `fileSourceFromHandle(...handles)` merges
handles from several providers into one source that routes to any of
them (upload once per provider, replay the same conversation anywhere).
- New fail-closed preflight: adapters that can consume file references
declare `supportsFileSources`; chat()/generateImage()/generateVideo()
reject file sources for every other adapter before a request is built.
Adapters written before this feature existed can no longer silently
mis-map a reference onto their URL/data branch — the failure class the
per-adapter sweep was policing by convention is now structural.
(openai-base's supportsFileIdInput gate is folded into the same flag.)
- Removing `value` from the file arm also makes fall-through code a
compile error — caught two latent OpenRouter paths that would have sent
a reference as a URL, now restructured with narrowed sources.
- Docs, agent skills, changeset, and all files-source tests updated to the
record shape; new preflight unit tests; e2e spec asserts the record
round-trip and lookup-miss rejection end-to-end.
# Conflicts:
# packages/openai-base/src/adapters/responses-text.tsGuard leftover source.value sites, run the fail-closed check on structured-output chat and embed, and preflight generateImage before RUN_STARTED.

- Around line 1838-1847: Extract the provider-specific file-source mappings from
the shared Responses adapter into a dedicated adapter or composable conversion
module under /adapters, covering the image, audio, and document branches around
isFileSource and their related mapping logic. Export the new module through the
adapters subpath, and have the shared adapter delegate to it while preserving
existing unsupported-source handling and output formats.

- Around line 94-96: Update the RUN_ERROR handling around the chunk-processing
logic to track occurrence separately from chunk.message, using a boolean such as
hasRunError. Set it when chunk.type is RUN_ERROR, and use that flag for the
response decision near the existing runError branch so an empty error message
still returns the error response rather than { ok: true }.

Aimock can emit RUN_ERROR after a successful file_id mapping. The route's job is to catch mapping/lookup misses, not mock-provider failures.
