Kimi K2.5's token usage drops 77% but holds Top 20 rank
Despite a 77% usage decline, Kimi K2.5 remains in the top 20.
Moonshot AI's Kimi K2.5, launched in January 2026 with a 262K context window and competitive pricing ($0.58 input / $3.02 output per 1M tokens), has experienced a dramatic 77% reduction in token usage between May 26 and July 20, 2026. Despite this drop, the model maintains a 16th place ranking on OpenCode Go usage, capturing 0.2% of the platform's observed 2 million token volume. This positions Kimi K2.5 as a niche player rather than a dominant force.
The significant usage decline raises questions about the model's market fit amid a crowded field of long-context AI offerings. While Kimi K2.5's cost structure and context length remain attractive on paper, the data suggests users have shifted toward alternatives during the observed two-month period. Moonshot AI will likely need to iterate on the model's reasoning capabilities or distribution strategy to reverse this trend and regain momentum.
