span-02 is a decision model: it answers typed questions about a state (JSON or text, plus up to 4 images) with a full probability distribution over the options, in the Decision Index /v1/systemone wire format. It is a fine-tune of Gemma 4 26B-A4B (mixture of experts, about 4B active parameters per token), quantized (NVFP4 experts, FP8 dense layers) and served by a custom Rust/CUDA engine for Blackwell GPUs (sm120: RTX 5090, RTX PRO 6000) that is included in this repo (engine/). Before answering it may think. If the top probability of the no-think answer is below 0.8, the model writes a greedy thought. Its length limit comes from a deterministic thought budget: a fixed cost model…

This profile connects the 1 model and dataset record shown below to their upstream cards and sources. The library counts describe SAVRN's coverage, rather than this publisher's entire output.
Published tasks: Image and text to text.
Reported licenses: apache-2.0. Open a record to review its specific license and conditions.
Compare model specifications, source dates, and hardware estimates on the individual records. Publisher identity verification is separate from a model's quality, deployment readiness, or suitability for your work.
