调研方向

先查看 lib/braintrust/contrib/ruby_llm/patcher.rb 和 lib/braintrust/contrib/ruby_llm/instrumentation/chat.rb,了解现有的 ChatPatcher 和 Chat#complete instrumentation。然后检查 lib/braintrust/contrib/ruby_llm/integration.rb,该文件目前只注册 ChatPatcher。完成的标准是:RubyLLM.embed、RubyLLM.paint 和 RubyLLM.transcribe 与现有的 chat API 一起完成 instrumentation。

描述

Summary

RubyLLM provides three AI inference APIs beyond chat completions — RubyLLM.embed, RubyLLM.paint, and RubyLLM.transcribe — none of which are instrumented by this SDK. The current RubyLLM integration only instruments Chat#complete and Chat#execute_tool.

What is missing

1. Embeddings — RubyLLM::Embedding.embed / RubyLLM.embed

Creates vector embeddings from text. Returns an Embedding object with vectors, model, and input_tokens. Supports provider/model selection and dimensions parameter. This is a core inference API used for RAG and semantic search.

2. Image generation — RubyLLM::Image.paint / RubyLLM.paint

Generates images from text prompts. Returns an Image object with url, data, mime_type, revised_prompt, model_id. Supports model/provider/size selection.

3. Audio transcription — RubyLLM::Transcription.transcribe / RubyLLM.transcribe

Converts audio files to text. Returns a Transcription object with text, model, language, duration, segments, input_tokens, output_tokens. Has built-in token tracking useful for cost attribution.

All three are stable public APIs available since RubyLLM 1.8+ (the minimum version this SDK targets). Each is a single-method call with a simple request/response pattern (no streaming), making instrumentation straightforward.

Braintrust docs status

not_found — The Braintrust RubyLLM integration docs at https://www.braintrust.dev/docs/integrations/ai-sdks/ruby-llm describe support for chat completions across multiple providers and tool/function call tracing but do not mention embeddings, image generation, or transcription.

  • lib/braintrust/contrib/ruby_llm/instrumentation/chat.rb — only wraps Chat#complete and Chat#execute_tool
  • lib/braintrust/contrib/ruby_llm/integration.rb — registers only the ChatPatcher
