Frequently Asked Questions

Which is better overall, DeepSeek V3 or Reka Flash 3?: We do not have preference Elo for both models, so we do not declare an overall winner. Compare the metrics that exist.
Which is better at coding, DeepSeek V3 or Reka Flash 3?: SWE-bench is missing for at least one model, so we do not rank coding from a single number.
Which is cheaper to run in production?: Reka Flash 3 output tokens are $0.2/1M versus $1.029/1M. Input prices and retry rates still move the real bill.
Which is faster, DeepSeek V3 or Reka Flash 3?: We do not have TTFT for both models.
Which has the larger context window?: DeepSeek V3 accepts 164k tokens versus 66k.
Can I self-host either model?: DeepSeek V3 is marked open-weights in our catalog. The other side is a closed API. Check the provider license before you ship weights.
Are these scores from CompareLLM’s own evals?: No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.
What does preference Elo mean on this page?: Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. DeepSeek V3 and Reka Flash 3 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
