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.

Lineage

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 Step-Audio-Chat 130B, 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.

Step-Audio-Chat 130B is a open weight model with a N/A context window. No explicit reasoning mode is documented in this profile.

Published weights or implementation resources are linked from the model card.

Step-Audio-Chat 130B is tracked because it appears in adu-bench. Voice-protocol results remain separate from BenchLM's weighted text-model ranking.

The profile has no source-displayable benchmark row yet.

Questions

How does Step-Audio-Chat 130B perform overall in AI benchmarks?

Step-Audio-Chat 130B 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 Step-Audio-Chat 130B open source?

Step-Audio-Chat 130B is an open-weight model from StepFun. 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 Step-Audio-Chat 130B have full benchmark coverage on BenchLM?

No. Step-Audio-Chat 130B currently has 0 source-displayable rows across 446 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 Step-Audio-Chat 130B?

Step-Audio-Chat 130B 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.
