Where it stands among the models you could choose
Ranked only among models available today (those you can call through OpenRouter), in the groups people choose between: the same price band, similar intelligence, the same speed, developers based in the same place, open weights. Retired models are left out.
| Among | Intelligence Index | Spring Prompt overall | Price | Speed |
|---|---|---|---|---|
| Models available today | – | – | 47th of 221Mistral Nemo | – |
| Models from developers based in China | – | – | 19th of 96Qwen3.5-9B | – |
| Open-weights modelsincluding 1 with weights announced but not yet published | – | – | 37th of 117Mistral Nemo | – |
The name under each rank is the leader of that group. Price is the developer's list price (or the typical OpenRouter host where we haven't read one) for three input tokens to one output; intelligence and speed are from Artificial Analysis (data sourced from Artificial Analysis); "similar intelligence" means within 4 points on its Intelligence Index. Developer locations are where each company is based, not where a model is served. Groups under 3 models are not ranked.
How good is it, and for what?
Each use case ranks the available models its benchmarks measured, then those priced under $0.25 per million tokens. The bar shows where it falls in that field, best to the right. Open a row for the results behind it.
