AnthropicLanguageModel
The AnthropicLanguageModel module provides the Anthropic implementation of Effect AI's LanguageModel service. It translates Effect AI prompts, tools, files, reasoning content, and Anthropic-specific options into Messages API requests, then converts normal and streaming Anthropic responses back into Effect AI response content with provider metadata.

Creates an Anthropic LanguageModel service from a model identifier and optional request defaults.
When to use
Use when you need to construct a LanguageModel.Service value backed by AnthropicClient inside an Effect.
Details
The returned effect requires AnthropicClient. Request defaults from the config option are merged with any Config service in the context, with context values taking precedence.

Represents a provider-defined tool that can be passed to the Anthropic API.
Details
These include Anthropic's built-in tools like computer use, code execution, web search, and text editing.

Added in v4.0.0
Source
Encoded Anthropic custom tool definition that can be sent in a Messages API request.
When to use
Use when you need to type or inspect the provider-specific request payload for a custom Anthropic tool.
Details
This type aliases the encoded Generated.BetaTool schema used for Effect user-defined and dynamic tools after conversion. It contains the tool name, optional description, and input_schema, plus Anthropic-specific fields such as strict and cache_control.
See
AnthropicProviderDefinedToolfor the request shape used by Anthropic built-in provider tools
Signature
type AnthropicUserDefinedTool = typeof Generated.BetaTool.Encoded;
Provides config overrides for Anthropic language model operations.
When to use
Use to apply Anthropic request configuration to one effect without changing the model's default configuration.
Details
The overrides are merged with any existing
Configservice for the duration of the supplied effect. Fields inoverridestake precedence over existing config, and the helper supports botheffect.pipe(withConfigOverride(overrides))andwithConfigOverride(effect, overrides).See
Configfor available Anthropic request configuration fields
