Kimi K3 Reasoning Scaler & Token Billing Simulator

Param: thinking_mode

Reasoning models scale test-time compute by generating hidden chain-of-thought (CoT) tokens. These tokens are billed at standard output rates and directly expand latency (TTFT) in exchange for higher GPQA Diamond and SWE-bench Verified problem resolve rates.

Frequently Asked Questions

Which is better overall, Kimi K3 or Mistral: Ministral 3 14B 2512?: 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, Kimi K3 or Mistral: Ministral 3 14B 2512?: 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?: Mistral: Ministral 3 14B 2512 output tokens are $0.2/1M versus $15/1M. Input prices and retry rates still move the real bill.
Which is faster, Kimi K3 or Mistral: Ministral 3 14B 2512?: We do not have TTFT for both models.
Which has the larger context window?: Kimi K3 accepts 1M tokens versus 262k.
Can I self-host either model?: Neither model is marked open-weights here. You are comparing hosted APIs.
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. Kimi K3 and Mistral: Ministral 3 14B 2512 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
