Summary
The Braintrust Go SDK instruments OpenAI, Anthropic, Google GenAI, sashabaranov/go-openai, LangChainGo, Firebase Genkit, Google ADK, and CloudWeGo Eino — but does not instrument the Cohere Go SDK (github.com/cohere-ai/cohere-go/v2). Cohere is a major AI provider with an official, actively maintained Go SDK offering meaningful generative-AI and embeddings execution surfaces.
No other Braintrust SDK (Python, TypeScript, Java, Ruby) has explicit Cohere SDK instrumentation either, making this a completely uninstrumented provider across the platform.
What is missing
A trace/contrib/cohere/ integration module that wraps execution calls on the Cohere Go client. The key execution surfaces are:
Chat / ChatStream — conversational model inference (streaming and non-streaming)Embed — embeddings generationRerank — semantic rerankingGenerate / GenerateStream — text generation (streaming and non-streaming)Classify — text classification
The Cohere client uses option.RequestOption functional options, which may allow middleware-style wrapping similar to the existing OpenAI/Anthropic integrations.
Braintrust docs status
Braintrust lists Cohere as a supported AI provider at the proxy/gateway level (AI Proxy supports routing and logging Cohere calls). However, there is no SDK-level tracing/instrumentation wrapper for Cohere in any Braintrust SDK. Status: supported at proxy level, not_found for SDK-level instrumentation.
