Kimi-K2-Instruct
It is hard to understate the impact of the model, which we've covered already. The new update is that they released a technical report today, with a bunch of nice methods, but nothing incredibly surprising. K2 has proven itself to be a capable model on various, unusual benchmarks, matching Opus on LMArena while becoming one of the most used models on OpenRouter.
Relative Adoption Metric contextualizes downloads against the model's size bucket.
OpenRouter publishes daily token totals for its ~50 most-served models. Days missing from the chart mean Kimi-K2-Instruct fell below that cutoff — not zero usage. OpenRouter logs usage separately per dated model version and per variant (like ":free"); the hub combines provider variants while keeping separately cataloged releases distinct.
