qwen3-next-80b-a3b-thinking

qwen3-next-80b-a3b-thinking is a efficient-tier language model from Alibaba Cloud with 80B parameters. qwen3-next-80b-a3b-thinking is an open-weights model, meaning the weights are publicly available for self-hosting, fine-tuning, and deployment on your own infrastructure — not just through Alibaba Cloud's API. It is a reasoning model that uses extended chain-of-thought (CoT) processing before producing a final answer — significantly more capable on complex math, science, and multi-step logic tasks, but slower and more expensive per query than standard models. Qwen is Alibaba's open-weights model family, with strong multilingual performance (especially Chinese/English) and a wide parameter range from 0.5B to 72B.

qwen3-next-80b-a3b-thinking is priced at $0.15/1M input tokens and $1.5/1M output tokens. Output tokens are 10× more expensive than input tokens — this ratio reflects the sequential nature of autoregressive generation, which requires a separate forward pass per output token versus parallel processing of all input tokens simultaneously. At a typical usage pattern of 1,000 input tokens and 500 output tokens per call, qwen3-next-80b-a3b-thinking costs approximately $0.90 per 1,000 API calls. Alibaba Cloud does not publish a prompt caching rate for this model, so repeated long contexts are billed at the standard $0.15/1M input rate.

Its 131K-token context window handles most long-document tasks — roughly 75,000 words or a full novel — without requiring chunking or retrieval augmentation. Median latency (P50 time-to-first-token) is approximately 2000ms — better suited to batch or async workloads where latency is less critical. Throughput is approximately 70 tokens/second — adequate for streaming at comfortable reading speed. Maximum output length is 33K tokens — sufficient for long-form content generation, detailed code files, and extended reports.

qwen3-next-80b-a3b-thinking is best suited to reasoning, cost. Supported capabilities include function calling / tool use for agentic workflows, streaming token output for real-time UIs. Function calling support makes it suitable for building AI agents, structured data extraction pipelines, and any workflow requiring the model to invoke external APIs or return typed JSON. When evaluating this model for a specific workload, the most important factors are: context window (does your input fit?), output price (how long are your generations?), and latency (is this interactive or batch?). The pricing table above shows how qwen3-next-80b-a3b-thinking compares to similar models across these dimensions.

qwen3-next-80b-a3b-thinking sits in the efficient tier — optimized for speed and cost while maintaining solid quality, ideal for high-volume or latency-sensitive workloads. As an open-weights model, qwen3-next-80b-a3b-thinking can be self-hosted on GPU compute (see the GPU rental comparison on this site) to eliminate per-token API costs entirely — the break-even point versus API pricing depends on your volume and the GPU hourly rate. When comparing qwen3-next-80b-a3b-thinking to alternatives, use the similar models section on this page to find models at comparable price points with different capability tradeoffs. The intelligence score (78/100) reflects aggregate benchmark performance — a useful proxy for general capability, though real-world performance varies significantly by task type. Always test with your specific prompts and use case before committing to a model for production.
