Best estimate from public evidence; the vendor did not disclose every value. The current model card reports a 4B Qwen3.5-4B-Base backbone with a 33.8M-parameter LoRA adapter and pointer head. The rounded 4B size is the model designation, not an exact combined parameter count. Dense architecture is inferred from the base checkpoint. Apache-2.0 weights, adapter/head, and runnable training/serving code are public. This checkpoint returns typed decisions, not generated text.
