Evidence: publisher corpus prior · leave-one-anchor-out calibrated · start rank interpolated from the launch card's own comparison table against resolved catalogue peers, discounted for measured cross-lab optimism. Prices are the lowest listed API offer per million tokens observed on the OpenRouter catalogue.
Scores are the sources' own published figures for each model's best evaluated configuration; ModelCap never re-runs a benchmark.

MiniMax M2-her ranks higher on the ModelCap Index as of 3 September 2026: #89 against #115. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it.
At least one of the two has no listed API price on ModelCap right now, so no price comparison is made.
Qwen3 4B Instruct 2507 has the larger context window: 262K tokens against 66K.
The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.
