Head-to-head comparison
North Mini Code (Cohere) and Mercury 2.5 Preview (Inception Labs) compared on the ModelCap Index, API price, context window, provider availability, weight access and every public benchmark board they share. Figures are the same ones shown on the live rankings; nothing here is a hidden score.
Snapshot as of 3 September 2026
As of 3 September 2026, Mercury 2.5 Preview holds the stronger ModelCap Index position (#94 vs #96); North Mini Code is cheaper per output token (Free/1M vs $0.15/1M); Mercury 2.5 Preview offers the longer context window (260K vs 256K tokens); and North Mini Code ships open weights.
Evidence: 1 public benchmark observation across 1 board · start rank inherited from the measured predecessor in its own product family, less a fixed succession penalty, until independent measurements replace it. 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.
