Summary
The cohere-ruby gem (~93K downloads, v1.0.2, April 2026) is the primary Ruby client for Cohere's API and is not instrumented by this SDK. Braintrust already documents Cohere as a supported AI provider with TypeScript and Python instrumentation, but there is no Ruby equivalent.
What is missing
No instrumentation exists for any cohere-ruby execution surface. Key APIs that should be instrumented:
Chat Completions
client.chat(model:, messages:, ...) — Conversational AI using Cohere's Command family of models. Supports streaming, tool use, and conversation history (via chat_history).
Text Generation
client.generate(prompt:, ...) — Text generation from a prompt. Supports model selection, max tokens, temperature, and stop sequences.
Embeddings
client.embed(model:, texts:, input_type:, ...) — Vector embeddings for text classification, semantic search, and clustering. Supports multiple embedding types (float, int8, uint8, binary).
Reranking
client.rerank(model:, query:, documents:, ...) — Document ranking by relevance to a query. Used in RAG pipelines to improve retrieval quality.
Braintrust docs status
supported — Braintrust documents Cohere as a supported AI provider at https://www.braintrust.dev/docs/integrations/ai-providers/cohere with TypeScript (cohere-ai v7.0.0+) and Python (cohere v5.0.0+) instrumentation. No Ruby SDK instrumentation is documented.
