  • 5b8c58f: feat(ai): decouple otel from core functions

  • 4e095b0: fix(ai): reject system messages in messages or prompt by default (opt-in)

Patch Changes

  • e3d9c0e: Add allowSystemInMessages option to ToolLoopAgent.

    This exposes the same option that exists on streamText and generateText, whether role: "system" messages are allowed in the prompt or messages fields. When unset, system messages are rejected because they can create a prompt injection attack risk. Ideally, use the instructions option instead. Set to true to allow system messages, or false to explicitly reject them.

    const agent = new ToolLoopAgent({
  model,
  allowSystemInMessages: true,
});

await agent.generate({
  messages: [
    { role: "system", content: "Server context" },
    { role: "user", content: "Hello" },
  ],
});

    The option can also be returned from prepareCall for dynamic per-call configuration.

  • 5f3749c: refactoring: rename toolNeedsApproval to toolApproval

  • 016e877: feat(ai): add instructions as the primary prompt option and deprecate system

  • 2fe1099: feat(ai): emit streaming chunks throught the onChunk callback

  • f319fde: feat(ai): validate tool context against contextSchema at runtime

    Tool execution and approval callbacks now validate each tool's toolsContext entry against its contextSchema. Invalid tool context now throws TypeValidationError with tool-context validation metadata in error.context.

  • 31ee822: refactoring(ai): extract filterActiveTools and expose it as experimental_filterActiveTools

  • b67525f: feat: instructions as prepareStep input

  • e68be55: fix(ai): skip stringifying text when streaming partial text

  • 1db29c8: feat(ai): break CallSettings apart into LanguageModelCallOptions and RequestOptions

  • 0a51f7d: fix(ai): enforce callOptionsSchema at runtime in ToolLoopAgent

    ToolLoopAgentSettings.callOptionsSchema was declared and documented as a runtime schema for options, but tool-loop-agent.ts never invoked it. Any invariant a developer encoded in the schema was silently bypassed at runtime, and unchecked options flowed straight into prepareCall and any instructions template that interpolated them.

    ToolLoopAgent.prepareCall now validates caller-supplied options against callOptionsSchema (when set) via safeValidateTypes, throwing InvalidArgumentError on failure before forwarding to prepareCall / generateText / streamText.

  • d1a8bed: fix(ui): export isDynamicToolUIPart from ai package

  • bcce2dd: feat(stream-text): expose standalone stream transformation helpers and deprecate the equivalent streamText result methods.

    The new toUIMessageChunk and toUIMessageStream helpers let you convert a streamText stream (or any compatible ReadableStream<TextStreamPart<TOOLS>>) into UI message chunks without going through the result object — useful for custom transports, tests, and other producers of TextStreamPart.

    result.toUIMessageStreamResponse(options) and result.pipeUIMessageStreamToResponse(response, options) can migrate by passing toUIMessageStream({ stream: result.stream, ...options }) to createUIMessageStreamResponse or pipeUIMessageStreamToResponse.

    The new toTextStream helper extracts text deltas from a streamText stream, so result.toTextStreamResponse(options) and result.pipeTextStreamToResponse(response, options) can migrate to createTextStreamResponse({ stream: toTextStream({ stream: result.stream }), ...options }) and pipeTextStreamToResponse({ response, stream: toTextStream({ stream: result.stream }), ...options }).

    result.toUIMessageStream, result.toUIMessageStreamResponse, result.pipeUIMessageStreamToResponse, result.toTextStreamResponse, and result.pipeTextStreamToResponse are now @deprecated. They still work in v7 and will be removed in the next major release. Migration snippets are in the v6 → v7 migration guide.

  • 2a74d43: Remove the deprecated experimental_prepareStep option from generateText.

    Use prepareStep instead.

  • 71d3022: fix(ai): unify generate text event callbacks

  • 6cca112: feat: add timeBetweenOutputTokensMs stats

  • fd4f578: fix(ai): exclude request and response bodies from text generation results by default to reduce memory usage.

  • 511902c: skip validation for tool parts in terminal states when tool schema is no longer registered

  • a5018ab: fix(ai): return schema-transformed elements in array output mode

    Previously final array output validation checked each element against the schema but returned the raw model output. Array output now returns the validated values so Zod transforms, coercions, defaults, and pipes are applied consistently with object output.

  • 531251e: fix(security): validate redirect targets in download functions to prevent SSRF bypass

    Both downloadBlob and download now validate the final URL after following HTTP redirects, preventing attackers from bypassing SSRF protections via open redirects to internal/private addresses.

  • eeefc3f: fix(ai): enforce timeout.stepMs for the whole step in streamText

    Previously streamText's step timer was cleared synchronously right after the step's stream was registered, before the stream produced anything, so stepMs never aborted a step that stalled before emitting content. The step timer now survives until the step's stream finishes or aborts, matching generateText. chunkMs/totalMs and normal step-finish cleanup are unchanged.

  • ec98264: feat(ai): allow multiple integrations to be registered at once

  • 43a6750: fix(ai): preserve allowSystemInMessages across streamText retries

  • 67df0a0: feat: add sensitiveContext property to Tool

  • b79b6a8: fix(ai): add approval guard for denied tool outputs

  • 81caa5d: fix(ai): remove ExtractLiteralUnion export

  • 4181cfe: fix(ai): harden getMediaTypeFromUrl against prototype-property collisions

    getMediaTypeFromUrl (used to infer media types for file-url / image-url parts) used ext in URL_EXTENSION_TO_MEDIA_TYPE against a plain object literal. A URL ending in .constructor therefore resolved through the prototype chain and returned the Object constructor function, violating the helper's : string return type and forwarding a non-string value to provider adapters.

    Switch to Object.hasOwn(...) so attacker-controlled extensions like .constructor cannot resolve to inherited Object.prototype keys.

  • 208d045: fix(ai): skip global telemetry registration when local integration defined

  • 5a6f514: feat(ai): support several tools in hasToolCall stop condition

  • ed74dae: fix(ui): make input optional on output-error tool and dynamic-tool UI message parts

    validateUIMessages rejected persisted assistant messages whose output-error tool parts had no input key. This happened for any errored tool call where the SDK set input: undefined (e.g. NoSuchToolError / InvalidToolInputError): JSON serialization stripped the undefined value, and Zod 4.4+ treats a missing z.unknown() key as a validation failure (previously it was implicitly optional). The schema now matches the runtime shape produced by process-ui-message-stream, so reloading a thread that contains an errored tool call no longer throws AI_TypeValidationError.

  • 594029e: feat(ai): wrap the model call in telemetry context

  • 426dbbb: fix(ai): reject streamText result promises with NoOutputGeneratedError when the model stream ends without producing any output. Previously such streams resolved with an empty step. Incomplete streams with partial output still resolve with the partial result.

  • 25a64f8: Remove deprecated experimental generateImage exports.

  • 75ef93e: remove the deprecated experimental_output alias and document the output migration for AI SDK 7

  • c26ca8d: Remove custom User-Agent header from HttpChatTransport to fix CORS preflight failures in Safari and Firefox

  • eaf849f: Rename rerank telemetry finish callback to onRerankEnd.

  • 664a0eb: feat (ai/core): support plain string model IDs in rerank() function

    The rerank() function now accepts plain model strings (e.g., 'cohere/rerank-v3.5') in addition to RerankingModel objects, matching the behavior of generateText, embed, and other core functions.

  • 08d2129: feat(mcp): propagate the server name through dynamic tool parts

    Adds first-class support for realtime (speech-to-speech) APIs:

    • Experimental_RealtimeModelV4 spec in @ai-sdk/provider with normalized event types and factory
    • OpenAI, Google, and xAI realtime provider implementations
    • openai.experimental_realtime() / google.experimental_realtime() / xai.experimental_realtime() work in both server and browser
    • .getToken() static method on each provider for server-side ephemeral token creation
    • experimental_getRealtimeToolDefinitions helper for provider session tool definitions
    • experimental_useRealtime hook in @ai-sdk/react returning UIMessage[] (aligned with useChat), with onToolCall and addToolOutput for client-driven tool execution
    • inputAudioTranscription session config for showing transcribed user audio messages when supported by the provider

  • e1bfb9c: feat(ai): remove unnecessary data from events

  • 375fdd7: fix: harden download URL SSRF guard against hostname and redirect bypasses

    validateDownloadUrl and the file download helpers (downloadBlob, download) could be bypassed in several ways when handling untrusted URLs:

    • A fully-qualified hostname with a trailing dot (e.g. localhost., myhost.local.) skipped the localhost/.local blocklist.
    • IPv6 addresses that embed an IPv4 address in their last 32 bits — IPv4-compatible (::127.0.0.1), IPv4-translated (::ffff:0:127.0.0.1), and NAT64 (64:ff9b::127.0.0.1, including the 64:ff9b:1::/48 local-use prefix) — were not decoded and checked against the private IPv4 ranges.
    • Redirects were validated only after fetch had already followed them, so the request to a redirect target (e.g. an internal/metadata address) had already been issued before the check ran.
    • Several reserved/internal address ranges were not blocked: CGNAT (100.64.0.0/10, used by some cloud providers for internal traffic), benchmarking (198.18.0.0/15), IETF protocol assignments (192.0.0.0/24), the reserved 240.0.0.0/4 block (including the 255.255.255.255 broadcast address), and IPv6 site-local (fec0::/10) and multicast (ff00::/8).

    The validator now strips trailing dots before the hostname checks and fully expands IPv6 addresses to detect embedded private IPv4 targets. The download helpers now follow redirects manually (redirect: 'manual'), re-validating each hop before requesting it, so an unsafe redirect target is never fetched. When a redirect cannot be inspected because the runtime returns an opaque response, the helpers fail closed (reject the redirect) on the server; only in a real browser — where SSRF is not reachable (fetch is constrained by CORS and cannot reach a server's internal network or cloud-metadata endpoints) — is the redirect followed natively so legitimate redirected downloads keep working.

  • 47e65d6: fix(ai): tag step/chunk timeout aborts with TimeoutError reason

    When timeout: { stepMs } or timeout: { chunkMs } fires, the abort reason is now a TimeoutError DOMException, matching what AbortSignal.timeout() produces natively. Consumers can distinguish a framework timeout from a user-initiated cancel via signal.reason.name === 'TimeoutError'.

  • 6a2caf9: Serialize undefined tool output to null in UI message chunks

  • 202f107: feat(ai): create a diagnostics channel to push event data

  • bae5e2b: fix(security): re-validate tool approvals from client message history before execution

    The approval-replay path in generateText/streamText (and WorkflowAgent.stream) reconstructed approved tool calls from the client-supplied messages array and executed them without re-validating input against the tool's schema or re-applying the approval policy. A client could forge an assistant message with a pre-approved tool-call part and have the server execute a tool with attacker-chosen arguments.

    The replay path now validates HMAC signature (when experimental_toolApprovalSecret is configured), re-validates tool-call input against the tool's input schema, and re-resolves the approval policy before execution.

  • f18b08f: fix: redact server error details from UI message streams by default

    toUIMessageStream, createUIMessageStream, and toUIMessageChunk defaulted their onError callback to getErrorMessage, which serializes the raw error (error.toString() / JSON.stringify(error)) into the client-facing { type: 'error', errorText } chunk — and also into tool-output-error parts. The documented default was () => 'An error occurred.', so applications relying on the documented behavior were unknowingly streaming server exception details (internal hostnames, paths, provider request data, validation inputs) to end users.

    The default onError now returns the documented generic 'An error occurred.'. Raw error details are only emitted when the developer explicitly supplies an onError handler. This also redacts tool-output-error and invalid-tool-input error text by default; pass an onError to surface richer messages.

  • b4507d5: fix(provider-utils): cancel response body on download rejection to prevent socket leak

    When a download was rejected early — because the Content-Length header exceeded the size limit, the response status was not ok, or a redirect resolved to a blocked URL — the fetch response body was left unconsumed and uncancelled. With WHATWG Fetch/undici this leaves the underlying TCP socket open instead of returning it to the connection pool, allowing an attacker-controlled origin to exhaust file descriptors and cause a denial of service. The body is now cancelled on all early-rejection paths in readResponseWithSizeLimit, download, and downloadBlob, and fetchWithValidatedRedirects cancels each redirect hop's body before following or rejecting the next hop.

  • f372547: fix(ai): fix providerExecuted tool approvals being passed to language model twice

  • 1e4b350: Honor tool.toModelOutput in WorkflowAgent.

    WorkflowAgent now routes successful local, provider-executed, and approved tool results through each tool's optional toModelOutput hook, matching generateText, streamText, and ToolLoopAgent. Previously the hook was ignored and results were always serialized as text or json.

    Internally exports the shared tool-result model-output helpers from ai/internal, and uses the shared getErrorMessage behavior for workflow tool error results.

  • 69d7128: fix(workflow): reuse the core tool-approval validation in WorkflowAgent

    WorkflowAgent.stream previously reconstructed approved tool calls with a copy of the core collection logic and validated them inline. Because the logic was duplicated, it could drift from the hardened generateText/streamText implementation. WorkflowAgent now collects approvals via the shared collectToolApprovals and re-validates each one through the shared validateApprovedToolApprovals (input-schema re-validation, HMAC signature verification when configured, and approval-policy re-resolution) in addition to its existing needsApproval guard, so a client-forged approval cannot execute a tool with unvalidated input. The duplicated collector was removed; collectToolApprovals and validateApprovedToolApprovals are now exported from ai/internal.
