# Pareto 26.9

> Pareto 26.9 is the September 2026 release of Unbiased's blended model: it selects frontier and open models for each request and blends their outputs into one answer. It is aimed at research, coding and agentic workflows and was superseded by Pareto 26.10, which is cheaper ($0.80 vs $2.50 per 1M input, $3.20 vs $7.50 per 1M output).
