GPT-6 Luna vs Qwen3 Coder Next

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-6 Luna is the cheaper of the two; neither can be ranked on quality here.

Neither model has 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-6 Luna vs Qwen3 Coder Next FAQ

Which is better, GPT-6 Luna or Qwen3 Coder Next?

GPT-6 Luna is the cheaper of the two; neither can be ranked on quality here. Neither model has 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-6 Luna cheaper than Qwen3 Coder Next?

GPT-6 Luna is cheaper. On a 3:1 input:output blend, GPT-6 Luna lists at $0.200 per million tokens and Qwen3 Coder Next at $0.290 — GPT-6 Luna is 45% cheaper. Input and output are priced separately — GPT-6 Luna charges $0.100 in and $0.500 out, Qwen3 Coder Next charges $0.120 and $0.800 — so the model that looks cheaper flips depending on how output-heavy your workload is.

Does GPT-6 Luna or Qwen3 Coder Next have a bigger context window?

GPT-6 Luna has the larger context window: 1.1M for GPT-6 Luna against 262K for Qwen3 Coder Next. 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-6 Luna and Qwen3 Coder Next support prompt caching?

Both publish a cached-input rate: $0.010 per million for GPT-6 Luna and $0.070 for Qwen3 Coder Next, against full input rates of $0.100 and $0.120. 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.
  • 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.
