Each logged request priced at the listed rates above for its own token counts, including cache reads and any higher rate for long prompts. Average output: 698 tokens per request. Both models are priced on the requests up to 262K tokens that fit in both context windows; band shares above describe all requests.

What to watch for

Qwen3 235B A22B's 262K window cannot take 12% of coding-agent requests, so the comparison uses only requests both can take. GPT-5.6 Sol is superseded: GPT-6.1 Sol costs $0.067 per request. The price is OpenRouter's listed rate on October 13, 2026, which can be a third-party host's; Alibaba's own API may charge differently.

FAQ

Is Qwen3 235B A22B cheaper than GPT-5.6 Sol for coding agents?

Yes, at the listed prices. 100 average coding-agent requests cost $0.96 on Qwen3 235B A22B and $10.09 on GPT-5.6 Sol. A median 16-request session costs $0.091 vs $1.22. Measured on 79,301 real coding-agent requests (Sep 13 to Oct 12, 2026), counting only the requests up to 262K tokens that both can take.

How much does a month of GPT-5.6 Sol vs Qwen3 235B cost?

For the median regular user in our data (1,478 requests in 30 days), about $127 on GPT-5.6 Sol and $13.05 on Qwen3 235B A22B at list price. Heavier users pay proportionally more.

GPT-5.6 Sol vs Qwen3 235B A22B: which is better for agents?

GPT-5.6 Sol scores higher on output quality (8.6/10 vs 3.8/10), while Qwen3 235B A22B is the cheaper option. GPT-5.6 Sol is best for existing GPT-5.6 Sol setups until they move to GPT-6.1 Sol; Qwen3 235B A22B is best for self-hosted setups that need a mid-size open-weight model. Live community votes on this page show what people actually prefer.

Can I switch between GPT-5.6 Sol and Qwen3 235B A22B in the same agent?

Yes. Model-agnostic agents (Cline, Aider, OpenClaw, Hermes Agent, Kilo Code, OpenCode) let you swap models per task. Many people route hard tasks to the stronger model and routine work to the cheaper one.
