[BOT ISSUE] omniai gem not instrumented

[braintrust-bot]

Summary

The omniai gem (~112K downloads, v3.6.0, March 2026) is an actively maintained multi-provider AI abstraction for Ruby and is not instrumented by this SDK. It provides a unified interface for chat, embeddings, speech, and transcription across OpenAI, Anthropic, Google Gemini, Mistral, DeepSeek, and Llama via modular provider gems (omniai-openai, omniai-anthropic, omniai-google, etc.).

What is missing

No instrumentation exists for any omniai execution surface. Key APIs that should be instrumented:

Chat Completions

• client.chat(prompt, ...) — unified chat interface across all providers, with support for stream:, tools:, and format: options
• Streaming responses via block callbacks

Embeddings

• client.embed(text, ...) — vector embeddings generation

Tool / Function Calling

• OmniAI::Tool — tool definitions with automatic execution during chat
• OmniAI::Schema — schema definitions for tool parameters

Speech / Transcription

• client.speak(text, format:) — text-to-speech generation
• client.transcribe(file) — audio-to-text transcription

Supported Providers (via separate gems)

• omniai-openai — OpenAI
• omniai-anthropic — Anthropic
• omniai-google — Google Gemini
• omniai-mistral — Mistral
• omniai-deepseek — DeepSeek
• omniai-llama — Llama
