About
Official Ruby SDK for the OpenAI API. Chat, embeddings, audio, and assistants from idiomatic Ruby.
What it does
This Ruby gem wraps remote model services in a single configurable client. It converts Ruby values into HTTP requests, parses replies into typed objects, streams server events, walks paginated collections, uploads files, and supports alternate provider routing through Azure OpenAI and Amazon Bedrock.
Why it's ranked here
A strong choice for current Ruby applications that need more than basic request wrappers. The combination of generated type surfaces, pooled standard-library transport, streaming bodies, retry policy, structured errors, provider support, and workload identity shows attention to production use rather than demonstration code.
What's good
Streaming responses avoid mandatory buffering, while pagination iterators hide repetitive page fetching. Yard, RBS, and RBI definitions serve several Ruby typing workflows. Request metadata preserves status, headers, and request identifiers. Custom transports remain possible without surrendering authentication, redirects, or API-level retries.
Tradeoffs
Ruby 3.3.0 or newer is required. Raw pathless input streams disable retries because they may not be rewindable. Injected HTTP clients must enforce timeouts and manage their own pools and lifecycle. Azure support targets its version-one API, not legacy deployment paths or dated version parameters.
How to use it well
Use it in typed Ruby services that call models, process streamed output, upload media, or enumerate large API collections. Keep one configured client around to benefit from connection pooling, and provide explicit file metadata for format-sensitive uploads. It does not manage the lifecycle of an injected transport for you.
Technical notes+
README.md documents Bundler installation, SSE streaming, auto-pagination, upload coercion, custom HTTP transport, mTLS, Azure OpenAI, Bedrock, and workload identity. lib/openai/client.rb centralizes resource access, environment-backed configuration, provider conflicts, two default retries, a 600-second default timeout, and workload-token refresh after an authentication failure. lib/openai/http_client.rb defines immutable request, response, metadata, and retry-event objects. lib/openai/net_http_client.rb implements pooled Net::HTTP transport, fiber-scheduler cooperation, streamed bodies, deadline recalibration, and normalized connection errors. lib/openai/errors.rb maps common HTTP statuses to specific exception classes. lib/openai/models.rb builds Sorbet aliases across generated model namespaces.
