[bot] Instrument AssemblyAI (568,268 weekly downloads)

[braintrust-bot]

Summary

github.com/AssemblyAI/assemblyai-go-sdk is AssemblyAI's official, actively released Go SDK (versioned releases up through v1.3.0+, e.g. "Utterance Detection and Word Search"). Its client exposes a dedicated LeMUR service — a genuine generative-AI execution surface distinct from transcription: LeMUR.Task(), LeMUR.Summary(), and question-answering calls send transcript context to an LLM (Claude 4 Sonnet/Opus and others) and return LLM-generated text, with configurable final_model, max_output_size, and temperature parameters. The SDK also exposes a RealTime streaming transcription service.

This is not a CRUD/admin API — LeMUR is a request/response (and prompt-parameterized) LLM execution call comparable in kind to the Chat/Generate surfaces already instrumented for other providers in trace/contrib/, and none of it is currently wired up in this repo.

Weekly downloads

Weekly downloads: 568,268 (as of 2026-08-29; https://api.npmjs.org/downloads/point/last-week/assemblyai — measured on assemblyai, the primary/flagship AssemblyAI client package, since Go module registries don't publish download counts)

Braintrust docs status: not_found

• https://www.braintrust.dev/docs/integrations — no AssemblyAI entry.
• AssemblyAI only appears in Braintrust's ecosystem indirectly, via the generic Vercel AI SDK OpenTelemetry provider list, not via a dedicated Braintrust SDK wrapper in any language.

No Braintrust SDK in any language has native AssemblyAI/LeMUR instrumentation today.

hey Abhijeet Prasad (@AbhiPrasad) Matt Perpick (@clutchski)

i tried the assemblyai sdk integration and found that the AssemblyAI/assemblyai-go-sdk repo was discontinued in april 2025. its own readme says it "has been discontinued and will no longer be maintained."

also, the lemur/v3/generate/* rest endpoints used by this sdk have since been retired. the current replacement is assemblyai's llm gateway at llm-gateway.assemblyai.com, which uses a different request format based on the openai-compatible /v1/chat/completions endpoint rather than the old lemur api.

i also verified this with the recorded cassettes, where the old api.assemblyai.com/lemur/v3/* endpoints are no longer available.

so i don't think adding instrumentation for the discontinued sdk and old lemur api would be the right approach. there are newer ways we can add assemblyai instrumentation, especially around the current llm gateway, which would be worth exploring instead.
