Analysis Summary

Solar Pro 2 (Non-reasoning) is Upstage's non-reasoning variant of the Solar Pro 2 model, released in July 2025. Its intelligence index of 13.6 and coding index of 11.3 place it in the limited tier relative to the current field. MMLU-Pro of 0.750 and GPQA of 0.561 indicate some general knowledge breadth, and IFBench of 0.337 reflects basic instruction following capability. The agentic index of 18.2 is low, limiting its use in multi-step workflows.

For businesses, this model is constrained to simple content drafting, classification, and lightweight summarisation tasks. The non-reasoning mode may offer latency advantages for high-volume, low-complexity pipelines, but the overall capability profile is modest. Coding and agentic reliability are insufficient for technical or autonomous workflows.

No pricing data is available. Teams evaluating Solar Pro 2 (Non-reasoning) should compare it directly against similarly priced compact models from more established providers before adoption, as the benchmark profile does not differentiate it strongly in any specific business use case.
