- At a typical 3:1 input-to-output ratio, the blended cost is about $0.66 per 1M tokens.
- Among 79 models with an output price, it is the #17 cheapest.
- The cheapest OpenRouter route charges $0.091 input / $0.18 output. That route is over 60% below list price — usually a promotion or a single provider, so check its reliability.
Sources & methodology
DeepSeek V4 Flash has no arena.ai Agents result yet, so on our leaderboard it is listed after models that do.
- arena.ai Agents — agent task success rate, 95% interval, sessions and rank (via the public Hugging Face dataset, CC BY 4.0).
- LMArena — Arena score (Text leaderboard with style control, the same view arena.ai shows by default), 95% confidence interval, votes and rank.
- Artificial Analysis — Intelligence / Coding Index, output speed and latency (medians).
- OpenRouter — Route prices, context length and listing date.
Arena scores use the Bradley-Terry model (not Elo); ± is the half-width of the 95% confidence interval. Latency figures are Artificial Analysis medians; for reasoning models, time to first token and to first answer include the thinking phase. Data syncs daily at 14:20 (UTC+8).
Limits: Arena scores come from anonymous users voting on chats, so they reflect conversational preference rather than agent or coding benchmarks; with few votes the interval is wide and ranks move. Prices and speeds change as providers update them.
