Cost per coding-agent request

Is GPT-5.5 or Qwen3.7 Max cheaper for coding agents?

For coding agents, GPT-5.5 costs 3.3x as much as Qwen3.7 Max per request ($0.21 vs $0.063 on our measured traffic), because GPT-5.5 lists at $5 input, $0.50 cached input and $30 output per million tokens against $1.475, $0.295 and $4.425 for Qwen3.7 Max, and GPT-5.5 charges more for prompts over 272K tokens.

List prices: OpenAI API pricing, OpenRouter listed price, checked 2026-10-13. Request costs: Standard Compute gateway data, 79,301 coding-agent requests from 75 users, Sep 13 to Oct 12, 2026. How we compute this

What to watch for

The gap widens on long prompts: under 100K tokens GPT-5.5 costs 2.8x as much per request, over 272K 4.9x. GPT-5.5 is superseded: GPT-6.1 Sol costs $0.067 per request.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 Qwen3.7 Max cheaper than GPT-5.5 for coding agents?

Yes, at the listed prices. 100 average coding-agent requests cost $6.29 on Qwen3.7 Max and $20.99 on GPT-5.5. A median 16-request session costs $0.79 vs $2.30. Measured on 79,301 real coding-agent requests (Sep 13 to Oct 12, 2026).

How much does a month of GPT-5.5 vs Qwen3.7 Max cost?

For the median regular user in our data (1,478 requests in 30 days), about $296 on GPT-5.5 and $103 on Qwen3.7 Max at list price. Heavier users pay proportionally more.

GPT-5.5 vs Qwen3.7 Max: which is better for agents?

GPT-5.5 scores higher on output quality (7.6/10 vs 6.3/10), while Qwen3.7 Max is the cheaper option. GPT-5.5 is best for existing GPT-5.5 setups on an API key until they move to GPT-6.1 Sol; Qwen3.7 Max is best for fast, long-context general work in Qwen-based stacks. Live community votes on this page show what people actually prefer.

Can I switch between GPT-5.5 and Qwen3.7 Max 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.
