Neither wins outright: OpenAI: GPT-5 Nano is the pick when cost matters at scale, Qwen: Qwen3.7 Plus (batch) when you need log-probabilities. In short: OpenAI: GPT-5 Nano when cost matters at scale, you need to fit long inputs in one request, you need file / PDF input, you need built-in web search; Qwen: Qwen3.7 Plus (batch) when you need log-probabilities, you want the newer model.
OpenAI: GPT-5 Nano is cheaper: $0.14 vs $0.40 per 1M tokens at a typical 3:1 input/output mix, 66% less. For 50,000 support conversations a month that is $11.75 against $35.65.
OpenAI: GPT-5 Nano costs $0.05 per 1M input tokens and $0.40 per 1M output tokens; Qwen: Qwen3.7 Plus (batch) costs $0.23 input and $0.92 output. Output tokens are billed separately, so long answers shift the gap.
OpenAI: GPT-5 Nano: 400K tokens, about 600 pages, against 262K (about 393 pages) for Qwen: Qwen3.7 Plus (batch).
Tool calling — OpenAI: GPT-5 Nano: yes, Qwen: Qwen3.7 Plus (batch): yes. JSON-schema structured output — OpenAI: GPT-5 Nano: yes, Qwen: Qwen3.7 Plus (batch): yes.
Yes, both accept image input.
