Voice benchmark evidence
Granite Speech 5.0 TurboCTC model notes is an owner-defined voice evaluation. Its result stays separate from BenchLM's weighted text-model ranking.
Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Granite Speech 5.0 470M TurboCTC, but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
Granite Speech 5.0 470M TurboCTC is a open weight model with a N/A context window. No explicit reasoning mode is documented in this profile.
Released August 25, 2026 under Apache 2.0 on Hugging Face (weights pushed August 4) as a 470M-parameter conformer CTC model trained on about 60,000 hours of English audio, with a non-commercial NC variant.
Granite Speech 5.0 470M TurboCTC is a display-only compact English ASR model for edge deployment. Transcription results remain separate from BenchLM’s weighted text-model ranking.
Speech or voice evidence appears above; text-model benchmark coverage remains empty.
Last updated October 25, 2026. Runtime fields remain blank until a sourced snapshot exists.
Deployment options
Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.
Published weights are available, but BenchLM does not yet have a sourced parameter and VRAM profile for this exact model. Hardware cost estimates stay unavailable until that sizing record is complete.
Estimate VRAM from known parametersQuestions
How does Granite Speech 5.0 470M TurboCTC perform overall in AI benchmarks?
Granite Speech 5.0 470M TurboCTC has published speech or voice results in Granite Speech 5.0 TurboCTC model notes. Those results remain separate from the weighted text-model ranking, so this profile does not assign a BenchLM score or overall rank. Use the linked evaluation's metric and run conditions to compare speech systems.
Is Granite Speech 5.0 470M TurboCTC open source?
Granite Speech 5.0 470M TurboCTC is an open-weight model from IBM. Its weights can be downloaded for local or hosted deployment, subject to the published license. Open weight does not automatically mean open source: training data and training code may remain private, and commercial restrictions can still apply.
Does Granite Speech 5.0 470M TurboCTC have full benchmark coverage on BenchLM?
No. Granite Speech 5.0 470M TurboCTC's speech or voice results appear in Granite Speech 5.0 TurboCTC model notes, but it has no published text-model benchmark rows. The voice evaluation does not fill the text-model coverage slots or produce an overall rank. Missing text coverage is not treated as a zero score.
What is the context window size of Granite Speech 5.0 470M TurboCTC?
Granite Speech 5.0 470M TurboCTC has a reported context window of N/A in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
