Values

build_request_body

</> 
pub fn build_request_body(
  messages: List(message.Message),
  tools: List(tool_definition.ToolDefinition),
  model: String,
) -> String

Build the JSON request body for the OpenAI Chat Completions API. Pure function — no IO.

build_request_body_with_thinking

</> 
pub fn build_request_body_with_thinking(
  messages: List(message.Message),
  tools: List(tool_definition.ToolDefinition),
  model: String,
  thinking_level: option.Option(thinking.ThinkingLevel),
) -> String

Build a Chat Completions request with an optional thinking level.

OpenAI-shaped APIs receive this as reasoning_effort. Unsupported levels are reported by the provider API.

build_stream_request_body

</> 
pub fn build_stream_request_body(
  messages: List(message.Message),
  tools: List(tool_definition.ToolDefinition),
  model: String,
) -> String

Build a Chat Completions request body for an SSE response.

The buffered builder remains unchanged for callers that own the request lifecycle. Streaming requests opt into the usage trailer explicitly.

build_stream_request_body_with_thinking

</> 
pub fn build_stream_request_body_with_thinking(
  messages: List(message.Message),
  tools: List(tool_definition.ToolDefinition),
  model: String,
  thinking_level: option.Option(thinking.ThinkingLevel),
) -> String

Build a streaming Chat Completions request with an optional thinking level.

parse_response

</> 
pub fn parse_response(
  raw: String,
) -> Result(inference.InferenceResult, error.AiError)

Parse an OpenAI Chat Completions JSON response into an InferenceResult. Pure function — no IO.
