📋 Minor Changes

• [#723](https://github.com/TanStack/ai/pull/723) [`22c9b42`](https://github.com/TanStack/ai/commit/22c9b42baec74914b720e440f29bd02be04eb164) - Surface fal's billed units as `result.usage`. The fal adapters now read fal's `x-fal-billable-units` response header off the result fetch and expose the billed quantity (`usage.unitsBilled`) on the generation result, so consumers can compute exact media-generation cost without wrapping `fetch` themselves.
• `TokenUsage` gains an optional `unitsBilled` field for usage-based (non-token) billing, denominated in the provider's priced unit.
• `falImage`, `falAudio`, `falVideo`, `falSpeech`, and `falTranscription` populate `result.usage.unitsBilled` when fal reports it.
• `VideoUrlResult` gains an optional `usage` slot; `getVideoJobStatus` now emits the `video:usage` event and returns `usage` when the completed result reports billed units.
• [#727](https://github.com/TanStack/ai/pull/727) [`7d44569`](https://github.com/TanStack/ai/commit/7d445693ea079d7a85498a4465179ddd5f548cb0) - Add an `'error'` terminal to `ToolCallState`. When a tool execution produces an output error, the StreamProcessor now transitions the `tool-call` part to `state: 'error'` instead of parking it at `'input-complete'`.
• ```ts
• if (part.type === 'tool-call' && part.state === 'error') {
• // render failure — no more inferring from output shape

📋 Patch Changes

• [#696](https://github.com/TanStack/ai/pull/696) [`ff267a5`](https://github.com/TanStack/ai/commit/ff267a5536327b006979f9f28ce2df7cc27f6e23) - Fix duplicate `TOOL_CALL_END` for server-executed tools. The adapter already streams `START`/`ARGS`/`END` for each tool call, but `chat()` emitted a second `END` afterwards with no matching `START` — an orphan event that AG-UI-strict consumers (e.g. `@ag-ui/client`'s `verifyEvents`) reject. The post-execution phase now only adds `TOOL_CALL_RESULT`. Fixes [#519](https://github.com/TanStack/ai/issues/519).
• [#734](https://github.com/TanStack/ai/pull/734) [`570c08a`](https://github.com/TanStack/ai/commit/570c08a8d1a35746c3d31a63188249cba2d2475a) - Fix the default debug logger dropping `meta` payloads on Cloudflare Workers / workerd ([#730](https://github.com/TanStack/ai/issues/730)). `ConsoleLogger` previously rendered `meta` with `console.dir`, which workerd never forwards to the terminal — debug mode printed category headlines but no request bodies, chunk contents, or `RUN_ERROR` payloads. The logger now detects the runtime: Node keeps the depth-unlimited `console.dir` dump, Cloudflare Workers renders `meta` as circular-safe pretty-printed JSON (workerd's own inspect truncates nested objects), and other runtimes (browsers, Deno, Bun) receive `meta` as an extra console argument so devtools keep collapsible trees. Detection checks workerd's `navigator.userAgent` marker before `process.versions.node`, since `nodejs_compat` emulates a Node version string.
• [#699](https://github.com/TanStack/ai/pull/699) [`215b6b4`](https://github.com/TanStack/ai/commit/215b6b401aa95d1d38da342aa09603cb1d616929) - Migrate the OpenAI realtime adapters from the retired Beta API (shut down 2026-05-12) to the GA API:
• `openaiRealtime()` now exchanges WebRTC SDP via `POST /v1/realtime/calls` (the Beta `?model=` shape returned `beta_api_shape_disabled`).
• `openaiRealtimeToken()` now mints ephemeral keys via `POST /v1/realtime/client_secrets` instead of the retired `/v1/realtime/sessions`, and parses the GA top-level `value`/`expires_at` response shape.
• `session.update` payloads use the GA shape: required `session.type`, `audio.input.transcription`, `audio.input.turn_detection`, `audio.output.voice`, `output_modalities`, and `max_output_tokens`. `temperature` was removed from the GA session config and is no longer sent (a debug log notes when it is dropped).
• Server events are handled under their GA names (`response.output_audio_transcript.*`, `response.output_audio.*`, `output_text`/`output_audio` content parts).
• The default realtime model is now `gpt-realtime`; the `gpt-4o-(mini-)realtime-preview` ids (shut down by OpenAI on 2026-05-07) were removed from `OpenAIRealtimeModel`.

• [#696](https://github.com/TanStack/ai/pull/696) [`ff267a5`](https://github.com/TanStack/ai/commit/ff267a5536327b006979f9f28ce2df7cc27f6e23) - Surface server-executed tool results in devtools from the `TOOL_CALL_RESULT` event. The devtools middleware previously read results only off `TOOL_CALL_END`, which the adapter emits before the tool runs (so it carries no result). Now that `chat()` no longer re-emits a post-execution `TOOL_CALL_END` (see the `@tanstack/ai` [#519](https://github.com/TanStack/ai/issues/519) fix), results travel on the spec-compliant `TOOL_CALL_RESULT` event — the middleware now handles it so devtools keeps showing server-tool output.

📋 Minor Changes

• [#727](https://github.com/TanStack/ai/pull/727) [`7d44569`](https://github.com/TanStack/ai/commit/7d445693ea079d7a85498a4465179ddd5f548cb0) - Add an `'error'` terminal to `ToolCallState`. When a tool execution produces an output error, the StreamProcessor now transitions the `tool-call` part to `state: 'error'` instead of parking it at `'input-complete'`.
• ```ts
• if (part.type === 'tool-call' && part.state === 'error') {
• // render failure — no more inferring from output shape
• }
• ```
