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.
