ParametersThe learned values that shape how a model responds. B means billion and T means trillion. For mixture-of-experts models, the total count is larger than the number active for each token. Parameter count alone does not measure quality. | 72B | 480B |
Context windowHow much information the model can work with in one request, measured in tokens — pieces of words or other data. This includes your question, attachments, conversation and reply. Limits can vary by model variant and provider. | 128k | 256k |
| API pricingUSD per 1M tokens · lower wins | ||
Cheapest inputLowest input rate across every provider on OpenRouter, the lab included. The cheapest endpoint may run a quantised build or a shorter context — see "Available from" on the model page. | — | $0.30DeepInfra |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | — | $1.00DeepInfra |

BullshitBench v2Nonsense detection — Given a confidently-worded but nonsensical prompt, does the AI spot that it makes no sense and push back — instead of playing along and inventing an answer? The score is how often it clearly called out the nonsense. Higher is better. | — | 20% |
SWE-Bench VerifiedCoding — Real coding tasks pulled from open-source projects — the AI has to find and fix actual bugs. A human-checked version of the original SWE-Bench. Higher is better. | 60.4% | — |

Kimi-Dev and Qwen3-Coder don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Kimi-Dev shipped 35 days before Qwen3-Coder, so benchmark comparisons should account for the intervening progress.
Kimi-Dev has 72B parameters, while Qwen3-Coder has 480B. Context windows are 128k (Kimi-Dev) vs 256k (Qwen3-Coder).
Direct benchmark comparisons are unavailable — Kimi-Dev and Qwen3-Coder don't publish scores on any of the same benchmarks.
