Master Qwen3.5 with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Explore the key features that make Qwen3.5 powerful for ai model apis workflows.
Qwen3.5 is used for language generation, reasoning, coding, summarization, long-context document work, and model evaluation. Model Studio lists qwen3.5-plus and qwen3.5-flash with 1M context, 64k max output, 80k thinking budget, function calling, built-in tools, and structured output support.
Qwen3.5 is best treated as a freemium API family rather than a purely free product. Model Studio lists a 1 million token free quota for selected International qwen3.5-plus and qwen3.5-flash entries, valid for 90 days after activating Model Studio. Global and Chinese Mainland deployment modes list no free quota for these entries.
Alibaba Cloud Model Studio lists Global qwen3.5-plus at $0.115 input and $0.688 output per 1M tokens for 0<Token≤128K, $0.287 input and $1.72 output for 128K<Token≤256K, and $0.573 input and $3.44 output for 256K<Token≤1M. International qwen3.5-plus is listed at $0.4 input and $2.4 output for 0<Token≤256K, and $0.5 input and $3 output for 256K<Token≤1M.
Alibaba Cloud Model Studio lists Global qwen3.5-flash at $0.029 input and $0.287 output per 1M tokens for 0<Token≤128K, $0.115 input and $1.147 output for 128K<Token≤256K, and $0.172 input and $1.72 output for 256K<Token≤1M. International, China Hong Kong, and EU qwen3.5-flash entries are listed at $0.1 input and $0.4 output per 1M tokens for 0<Token≤1M.
Yes. Alibaba Cloud Model Studio lists qwen3.5-plus and qwen3.5-flash with 1M context, 64k max output, and an 80k thinking budget. It also lists qwen3.5-397b-a17b, qwen3.5-122b-a10b, qwen3.5-27b, and qwen3.5-35b-a3b with 256k context and 64k max output.
Qwen3.5 differentiates itself through Qwen research lineage, long-context options, multiple model sizes, and Alibaba Cloud deployment options. It is especially relevant for teams comparing price-performance across model families, while buyers that need enterprise terms should still validate support, compliance, and uptime commitments through the official commercial channel.
Now that you know how to use Qwen3.5, it's time to put this knowledge into practice.
