Step3-VL-10B

StepFun · 10B dense

A 10B starter base for image, text and video

A 10B vision-language model open-sourced by StepFun in June 2026, Apache-2.0 and 128K: perception 88, documents 86, charts 82 and a composite of 80.4. Its value is single-GPU deployment, fine-tunability and clean licensing, not the score; video 74, generation 55 and agents 72 are the boundaries of an entry tier.

Bottom line

Best for teaching, prototypes and edge experiments: 10B, Apache-2.0, single-GPU inference and low modification cost. Production use must respect the boundaries — video 74 is sparse-frame only, generation 55 is effectively unusable, and complex agents will not hold.

Strengths and limitations

Strengths

  • 10B plus Apache-2.0: the lowest barrier for single-GPU deployment and coursework.
  • Perception 88 and documents 86 are solid for an entry tier.
  • Grade A: weights, evaluation scripts and model card are public.

Limitations

  • Video 74: sparse-frame understanding only.
  • Generation 55: no usable image generation or editing.
  • Agents 72 and ecosystem 88: complex orchestration and hosted services must come from elsewhere.

Price and real cost

List price

—N/A

Open weights; runs on one GPU. For 1,000 images at 1,024px, ~1,100 image tokens each and 300 output tokens, the monthly cost is about ¥0.0 (assuming input at 25% of output price).
