Summary

Pareto 26.10 Preview does not yet carry a Known Good Index score — the index needs at least one science, one mathematics and one coding result. It accepts text, image input, outputs text, and supports a 1.05M-token context window.

Pricing is $0.80 per 1M input tokens (below the $1.99 average) and $3.20 per 1M output (below the $9.18 average). Cached input reads at $0.030 per 1M, a 96% discount on its input price. At 23 tokens per second it sits in the slowest quarter of the models we track.

Blended Price

USD per 1M tokens at a 3:1 input:output blend. Live from OpenRouter, cross-checked against models.dev. Lower is better. Ranked against the 498 models priced above zero, which is the population the chart draws; excludes 37 published at no cost (free and promotional tiers).

We publish blended price rather than cost-per-task. Cost-per-task requires token counts from an evaluation suite we do not run. Blended price is computed from published rates and is fully reproducible — see the pricing methodology.
