GPT-3.5 Turbo vs Qwen3.6 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

GPT-3.5 Turbo is the cheaper of the two; neither can be ranked on quality here.

GPT-3.5 Turbo 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-3.5 Turbo vs Qwen3.6 27B FAQ

Which is better, GPT-3.5 Turbo or Qwen3.6 27B?

GPT-3.5 Turbo is the cheaper of the two; neither can be ranked on quality here. GPT-3.5 Turbo does not have a published LiveBench run, so this comparison covers price, context and declared capabilities only.

Is GPT-3.5 Turbo cheaper than Qwen3.6 27B?

GPT-3.5 Turbo is cheaper. On a 3:1 input:output blend, GPT-3.5 Turbo lists at $0.750 per million tokens and Qwen3.6 27B at $0.915 — GPT-3.5 Turbo is 22% cheaper. Input and output are priced separately — GPT-3.5 Turbo charges $0.500 in and $1.50 out, Qwen3.6 27B charges $0.320 and $2.70 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Does GPT-3.5 Turbo or Qwen3.6 27B have a bigger context window?

Qwen3.6 27B has the larger context window: 16K for GPT-3.5 Turbo against 262K for Qwen3.6 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.

Do GPT-3.5 Turbo and Qwen3.6 27B support prompt caching?

Qwen3.6 27B publishes a cached-input rate of $0.150 per million tokens against a full input rate of $0.320. The catalogue lists no separate cached rate for GPT-3.5 Turbo, 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.
