Unreleased - ReleaseDate

Added

  • Added support for SubAgents
  • Added support for custom HTTP headers in LanguageModelRequest, allowing request header injection and overriding provider default headers. by @gaki2
  • Added support for custom HTTP headers in EmbeddingModelRequest, allowing request header injection and overriding provider default headers.
  • Add grok-4-20-beta as a model in xAI provider.
  • Added support for custom HTTP request body for LanguageModelRequest and all providers, allowing request body injection and overriding provider default body. by @gaki2
  • Added support for custom HTTP request body for EmbeddingModelRequest, and for all providers, allowing request body injection and overriding provider default body.
  • Added Provider level HTTP headers to LanguageModelRequest and EmbeddingModelRequest. allowing request header injection on provider intialization.
  • Added async tool executor support through ToolExecute::from_async(...).
  • Added support for #[tool] pub async fn ... tool bodies.
  • Added ToolContext for tools, enabling runtime-aware execution and access to LanguageModelOptions.
  • Added optional tool stream sender support in ToolContext, allowing tools to emit LanguageModelStreamChunkType from the tool body.
  • Added new LanguageModelStreamChunkType chunk types: ReasoningStart, ReasoningDelta, ReasoningEnd, ToolCallStart, ToolCallDelta, ToolCallAvailable, and ToolCallEnd
  • Added ToolCall progress stream support for vercel-ai-sdk-ui integration.

Changed

  • ToolExecute now uses a trait-based executor abstraction internally, allowing both synchronous and asynchronous tool executors behind the same Tool API.
  • ToolExecute::call(...) is now async and must be awaited. This is a breaking change for direct callers of the tool executor API.
  • ToolList::execute(...) and ToolExecute::call(...) is now async, takes ToolContext as the first parameter as the first parameter for runtime-aware execution.
  • Removed ToolExecute::new(...) in favor of the explicit from_sync(...) and from_async(...) constructors.
  • Start and End language model stream chunk types are now TextStart and TextEnd.

0.5.2 - 2026-02-25

Fixed

  • Fixed DynamicModel builder bug where .model_name(...) was overwritten on .build(), causing empty model IDs.

Added

  • Added optional jitter feature flag for backoff jitter (pulls in fastrand)
  • Added separate shared connection pools
  • Added retry logic for transport-level errors (timeout, connection refused)

Changed

  • Switched TLS backend from native-tls to rustls (removes OpenSSL dependency)
  • Reduced default max_retries from 5 to 3, initial_wait from 1s to 500ms and reduced default max_wait from 30s to 20s

0.3.0 - 2025-12-29

Added

  • Added Messages type alias for Vec<Message>.
  • Added seamless integration to work with vercel's ai-sdk-ui.
  • Added seamless integration to work with axum + vercel's ai-sdk ui.

  • Automatic retry logic with exponential backoff for rate limit errors (429)

Changed

  • Model capabilities are now enforced at compile time via marker traits, preventing invalid feature usage (e.g., tool calls on unsupported models).
  • Updated tool macro to require a return type of Tool
  • User does not need to import aisdk::core::tools::ToolExecute anymore to work with the tool macro
