By price, qwen3.5 ranks 6th cheapest of 68 on input and 6th on output. Its quality score of 91 ranks 17th of 68, and on value (quality score ÷ output price) it ranks 3rd of 68. Its blended rate sits 96% below the catalog average.
In real billing terms: a support chatbot handling 50,000 turns a month (2,000 input / 500 output tokens each) costs about $14 per month on qwen3.5, while a RAG workload of 20,000 queries (8,000 input / 800 output tokens each) runs about $18. Because output is priced 1.5× input here, long-generation tasks scale cost fastest — cap output length before you optimise anything else.
A 1000K context window holds roughly 1,333 pages of A4 text (at ~750 tokens per page), ranking 22nd of 68 here. That is enough to drop in an entire technical manual or several source files at once, which suits long-document summarization and codebase-wide analysis. Output runs at about 85 tok/s (42nd fastest of 68), acceptable interactively, though long responses will feel slow.
We track 6 Alibaba models, and qwen3.5's blended rate sits 85% below that provider's average. Among the models tracked here it is already one of the cheapest options at this quality level. Going the other way, deepseek-reasoner-v4 scores 92 on quality for about 383% more.
The closest model in Alibaba's line-up is qwen-turbo ($0.05 input / $0.20 output, quality 74). Against it, qwen3.5 scores 17 points higher on quality, runs 155 tok/s slower (about 65%), costs 22% more blended. When two models sit this close on price, the deciding factor is usually the quality ceiling — run both against your real prompts before picking.

Where it fits — and where it doesn't
Good fit
- Coding: writing, refactoring and debugging across multi-file project context.
- Reasoning: multi-step decomposition, planning and tasks that need rigorous inference.
- Long documents: a 1000K window ingests a full contract, paper or large codebase in one pass.
- High-volume, cost-sensitive batch work: low rates suit classification, tagging and summarization at scale.
- Multimodal input: handles images, screenshots and scanned documents directly.
Poor fit
- No obvious disqualifiers — still benchmark on your own data before committing.
