Frequently Asked Questions about Qwen3.5 397B-A17B

How much does the Qwen3.5 397B-A17B API cost per 1M tokens?+

Qwen3.5 397B-A17B by Alibaba is priced at $0 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 0% discount.

Should I use a $20/month subscription or the Qwen3.5 397B-A17B pay-as-you-go API?+

A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.

How many words and pages fit in Qwen3.5 397B-A17B's context window?+

Qwen3.5 397B-A17B features a 262K tokens context window, which equals approximately 196,608 English words or ~524 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run Qwen3.5 397B-A17B locally on my own GPU (Open Weights)?+

Yes, Qwen3.5 397B-A17B (397B total (17B active MoE)) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.

Does Alibaba train on data sent to the Qwen3.5 397B-A17B API, and is commercial use allowed?+

100% Isolated when self-hosted on private GPUs or VPC. License tier: Permissive Open-Weights (Apache 2.0 / MIT Commercial). Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.

How does Qwen3.5 397B-A17B perform on coding and reasoning benchmarks?+

Qwen3.5 397B-A17B achieves a composite Intelligence Index of 86/100, scoring 58% on SWE-bench Verified, 70% on GPQA Diamond, 83.5% on MMLU-Pro, and 1385 pts on Chatbot Arena Elo.

What is Qwen3.5 397B-A17B best used for?+

Qwen3.5 397B-A17B is best suited for: Conçu pour l’auto-hébergement sur infrastructure privée, le fine-tuning et la souveraineté des données, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 86/100, un contexte de 262K et un débit de 64 tok/s, Qwen3.5 397B-A17B s’impose comme une valeur sûre de la gamme Alibaba.
