SpaceXAI: Grok STT 1.0

x-ai/grok-stt-1.0

Our take

AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.

According to OpenRouter's catalog, Grok STT 1.0 is SpaceXAI's speech-to-text model, reachable through a REST /v1/stt endpoint. The catalog reports transcription output with word-level timestamps, optional speaker diarization, and multichannel audio input. No benchmark results are listed, and an independent model card was not available in this source pack, so accuracy and language coverage remain unverified. The entry also carries an expiration date of 2026-11-15, which may indicate limited catalog availability.[1]

Strengths

  • Catalog-reported word-level timestamps in the transcription output.[1]
  • Optional speaker diarization and multichannel audio input, per the catalog.[1]
  • Accessed through a dedicated REST /v1/stt endpoint, per the catalog.[1]

Limitations

  • Evidence comes solely from OpenRouter's catalog; no independent model card or measured accuracy data was available in this source pack, so real-world performance needs workload validation.[1]
  • The catalog lists an expiration date of 2026-11-15, which may signal time-limited availability.[1]
  • Supported languages, maximum audio duration, and transcription quality are undocumented in the supplied source.[1]

Where to use it

  • May suit subtitling or captioning pipelines that benefit from word-level timestamps; validate accuracy on your own audio first.[1]
  • Could fit meeting or interview transcription where speaker attribution helps; diarization is catalog-reported, not measured.[1]
  • Potentially applicable to multichannel recordings such as contact-center audio; test against your workloads before adopting.[1]

Tasks and capabilities

A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.

How grades work

Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.

  • S — S — top 10% of the cohort
  • A — A — next 20% of the cohort
  • B — B — next 30% of the cohort
  • C — C — below the B band
