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. | 284B | — |
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. | 1M | 128k |

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. | $0.04OpenInference | — |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | $0.136OpenInference | — |

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. | 18% | — |
LiveCodeBenchCompetitive coding — Coding problems published so recently the AI can't have seen them in training — a contamination-free test of raw programming skill. Higher is better. | 91.6% | — |
GPQA DiamondScience — Graduate-level science questions in biology, physics, and chemistry — hard enough that subject-matter PhDs score around 65%. Higher is better. | 88.1% | — |

DeepSeek-V4-Flash and Grok‑2 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Grok‑2 shipped 618 days before DeepSeek-V4-Flash, so benchmark comparisons should account for the intervening progress.
Context windows are 1M (DeepSeek-V4-Flash) vs 128k (Grok‑2). DeepSeek-V4-Flash is open weight, while Grok‑2 is closed.
Direct benchmark comparisons are unavailable — DeepSeek-V4-Flash and Grok‑2 don't publish scores on any of the same benchmarks.
