Mi:dm K 3.0 Pro vs Qwen3.8 27B

Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.

OpenRouter + LiveBenchAll comparisonsFull leaderboard

Mi:dm K 3.0 Pro is the cheaper of the two; neither can be ranked on quality here.

Mi:dm K 3.0 Pro does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only. A missing score means "not evaluated", not "worse" — the right way to separate these two is an eval on your own workload.

Mi:dm K 3.0 Pro is the cheaper of the two; neither can be ranked on quality here.

Is Mi:dm K 3.0 Pro cheaper than Qwen3.8 27B?

Does Mi:dm K 3.0 Pro or Qwen3.8 27B have a bigger context window?

Qwen3.8 27B has the larger context window: 262K for Mi:dm K 3.0 Pro against 1.0M for Qwen3.8 27B. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.

Both publish a cached-input rate: $0.040 per million for Mi:dm K 3.0 Pro and $0.037 for Qwen3.8 27B, against full input rates of $0.200 and $0.150. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • Scores — LiveBench release 2026-11-06, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
  • Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
  • “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.

Published benchmarks rank models on someone else's tasks. Before committing, see LLM & agent evaluation for building an eval on your own.
