Measured Coverage and Estimates
Kimi K2.5 has 22 of 39 tracked IQ benchmark inputs across 7 of 7 dimensions. Raw benchmark tables contain source-backed results only. Derived IQ combines all six dimensions using the shared scoring methodology, including estimates where direct coverage is incomplete.
Among dimensions with direct benchmark coverage, this profile's highest estimated scores are Academic Reasoning (IQ 123) and Computer Use (IQ 117). These dimension estimates can include statistical adjustments or predecessor priors; they are not raw benchmark percentages or claims of real-world task success.
Benchmark versions, evaluation harnesses, and coverage affect comparisons; a missing result is not a score of zero. See the scoring methodology for estimation and uncertainty limits.

Frequently Asked Questions
- What is the IQ of kimi-k2.5?
- kimi-k2.5 has an estimated IQ of 110, which ranks #74 out of 164 public models on the AI IQ leaderboard. The score combines seven equally weighted reasoning dimensions using measured benchmark results and conservative estimates for missing coverage.
- What is the EQ of kimi-k2.5?
- kimi-k2.5 has an estimated EQ of 115. EQ measures emotional reasoning — how well a model reads and responds to emotional context — and is scored separately from IQ.
- How much does kimi-k2.5 cost?
- kimi-k2.5 costs $0.60 per million input tokens and $2.75 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $2.79 per million input-plus-output tokens.
- Is kimi-k2.5 open source?
- Yes — kimi-k2.5 is an open-weights model: its trained weights are published, so it can be downloaded and self-hosted.
- When was kimi-k2.5 released?
- kimi-k2.5 was publicly released on January 27, 2026.
- How fast is kimi-k2.5?
- In independent measurements, kimi-k2.5 generates about 60 tokens per second, with a typical response time of about 60 seconds.
