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.

The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. 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.
The profile has no source-displayable benchmark row yet.

Frequently asked questions
How does Granite Speech 5.0 470M TurboCTC perform overall in AI benchmarks?
Granite Speech 5.0 470M TurboCTC does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
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 currently has 0 source-displayable rows across 434 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
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.
