GPT-5.4 Nano vs Qwen3.6 Flash

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

GPT-5.4 Nano and Qwen3.6 Flash are priced within ~10% of each other.

Qwen3.6 Flash 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.

GPT-5.4 Nano vs Qwen3.6 Flash FAQ

Which is better, GPT-5.4 Nano or Qwen3.6 Flash?

GPT-5.4 Nano and Qwen3.6 Flash are priced within ~10% of each other. Qwen3.6 Flash 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.

Is GPT-5.4 Nano cheaper than Qwen3.6 Flash?

They cost about the same. Both land near $0.463 per million tokens on a 3:1 input:output blend, so price is unlikely to be the deciding factor between them.

Does GPT-5.4 Nano or Qwen3.6 Flash have a bigger context window?

Qwen3.6 Flash has the larger context window: 400K for GPT-5.4 Nano against 1M for Qwen3.6 Flash. 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.

Do GPT-5.4 Nano and Qwen3.6 Flash support prompt caching?

GPT-5.4 Nano publishes a cached-input rate of $0.020 per million tokens against a full input rate of $0.200. The catalogue lists no separate cached rate for Qwen3.6 Flash, which means the provider does not price it separately here — not that caching is unavailable.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • ScoresLiveBench release 2026-06-25, 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.
