Most-used AI models for summarization
gpt-oss-120b is the most-used model for summarization on OpenRouter, handling 15.9% of requests classified as summarization over the last 7 days.
This ranks models by how often they are actually chosen for summarization 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.

| 8 | Gemma 4 26B A4B | 3.1% | 1.3% | $0.070 | 262K |
| 9 |  Claude Haiku 4.5 | 3.0% | 1.1% | $1.00 | 200K |
| 10 | Gemini 3.1 Flash Lite | 2.9% | 0.90% | $0.250 | 1.0M |
Reading the two columns together: Gemini 3 Flash Preview takes a noticeably larger share of tokens than of requests — meaning it is being used for the longer, heavier summarization jobs rather than quick one-shot calls.
