About
Official Go library for the OpenAI API — chat, completions, embeddings, audio, batch, files, and the Responses API.
What it does
A Go client that turns OpenAI REST requests and responses into typed application code. It supports ordinary and streaming generation, multi-turn state, tool calling, structured output, audio, asynchronous batches, administration, and beta services.
Why it's ranked here
The case is strong for Go teams that want broad API coverage without hand-building HTTP requests. Typed parameters, streaming support, pagination, raw JSON access, configurable request options, and tested workload identity handling make it suitable for serious integrations.
What's good
The library distinguishes required, optional, omitted, and explicit null values during JSON serialization. It exposes typed unions for varied API shapes, preserves unmodified response JSON, supports automatic pagination, and lets callers apply client-wide or request-specific options.
Tradeoffs
Current releases require Go 1.25, while teams on Go 1.22 through 1.24 must pin an older release without guaranteed fixes or security backports. The README also warns of limited breaking changes. Generated unions and parameter wrappers add ceremony, and deprecated Assistants surfaces remain exposed.
How to use it well
Use it in Go services that need typed access to OpenAI, especially for streaming, conversations, tool workflows, structured output, audio, or batch processing. Prefer the Responses API for new model interactions. Keep tool execution and result validation in application code. Schema generation still needs separate code or a third-party package.
Technical notes+
README.md positions Responses as the primary API, documents environment-based API key lookup, streaming, conversation continuation, tool calls, and structured outputs. go.mod declares module github.com/openai/openai-go/v3 with Go 1.25.0 and direct Azure, AWS, gjson, and sjson dependencies. batch.go shows generated HTTP service methods, cursor pagination, required identifier checks, bearer authentication, response field metadata, and RawJSON support. beta.go, admin.go, audio.go, audiospeech.go, betachatkit.go, betathread.go, and betaassistant.go expose generated service trees; the thread and assistant surfaces are deprecated in favor of Responses. auth_test.go exercises workload identity token exchange, bearer injection, replayable request bodies, and a single retry after HTTP 401. batch_test.go covers create, retrieve, list, and cancel operations against a configurable test server.
