This ranks models by how often they are actually chosen for debugging in production traffic, not by benchmark score. Adoption reflects price, latency and availability as much as raw capability — which is exactly why it often disagrees with the benchmark leaderboards, and why it is worth reading alongside them.

Reading the two columns together: DeepSeek V4 Flash 0423, GPT-5.6 Luna, nemotron-3-ultra-550b-a55b-20260604:free take a noticeably larger share of tokens than of requests — meaning they are being used for the longer, heavier debugging jobs rather than quick one-shot calls.

Frequently asked

What is the most-used AI model for debugging?

DeepSeek V4 Flash 0423 is the most-used model for debugging on OpenRouter, handling 11.1% of requests classified as debugging over the last 7 days. It is followed by GLM 5.2 (9.7%) and MiMo-V2.5 (9.5%).

Is this a benchmark ranking?

No. This ranks by how often each model is actually chosen for debugging in production traffic through OpenRouter — real-world adoption, which reflects price and availability as much as capability. For capability-based rankings, see the benchmark leaderboards.

How much of all AI traffic is debugging?
