GPT-6.1 Sol vs Qwen3.8 Flash FAQ

Which is better, GPT-6.1 Sol or Qwen3.8 Flash?

GPT-6.1 Sol scores higher, Qwen3.8 Flash costs less — it depends on your workload. GPT-6.1 Sol is ahead by 38.5 points overall, and Qwen3.8 Flash lists 17× cheaper per blended million tokens. Whether 38.5 points is worth that depends on how much a wrong answer costs you. Qwen3.8 Flash also leads on measured cost per point of capability, at $0.2009 per point.

Is GPT-6.1 Sol cheaper than Qwen3.8 Flash?

Qwen3.8 Flash is cheaper. On a 3:1 input:output blend, GPT-6.1 Sol lists at $4.00 per million tokens and Qwen3.8 Flash at $0.230 — Qwen3.8 Flash is 17× cheaper. Input and output are priced separately — GPT-6.1 Sol charges $2.00 in and $10.00 out, Qwen3.8 Flash charges $0.150 and $0.470 — so the model that looks cheaper flips depending on how output-heavy your workload is.

GPT-6.1 Sol vs Qwen3.8 Flash: which scores higher on benchmarks?

GPT-6.1 Sol scores 85.4 and Qwen3.8 Flash scores 47.0 overall on LiveBench, the mean of its seven categories. That is a 38.5-point lead for GPT-6.1 Sol. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.

Which gives better value for money, GPT-6.1 Sol or Qwen3.8 Flash?

Qwen3.8 Flash. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. GPT-6.1 Sol works out at $0.4971 per point and Qwen3.8 Flash at $0.2009.

Does GPT-6.1 Sol or Qwen3.8 Flash have a bigger context window?

They are effectively the same — 1.1M for GPT-6.1 Sol and 1M for Qwen3.8 Flash.

Do GPT-6.1 Sol and Qwen3.8 Flash support prompt caching?

Both publish a cached-input rate: $0.100 per million for GPT-6.1 Sol and $0.016 for Qwen3.8 Flash, against full input rates of $2.00 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 2026-09-02, 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.
