What is Qwen 3 Next 80b?
Qwen 3 Next 80B is Alibaba's open-weight sparse Mixture-of-Experts language model with 80 billion total parameters and 3 billion active per token. Released in September 2025, it uses hybrid attention and multi-token prediction to deliver high throughput across contexts up to 256K tokens.
Use it privately on Venice
Run Qwen 3 Next 80B on Venice with zero retention — your prompts are not stored or used for training. Venice hosts the open weights directly with tool use, web search, and structured JSON output available, giving you permissionless sovereignty over your inference without Big-Tech surveillance.
What can it do?
- •Extreme parameter efficiency — 80B total parameters with only 3B active per token, outperforming dense Qwen3-32B at under one-tenth the training cost.
- •Ultra-long context performance — hybrid attention enables 10× higher throughput than dense models beyond 32K tokens and strong results up to 256K tokens.
- •Fully open weights released under Apache 2.0, enabling self-hosting, fine-tuning, and auditability.
- •On Venice it supports tool use, web search, and structured JSON schema output for agentic and automation workflows.
- •Benchmarked on par with Qwen3-235B-A22B-Instruct on certain tasks despite a fraction of the active parameters.
- •MoE architectures can exhibit higher latency for single-token streaming compared to similarly priced dense models.
- •Instruction-following on precise multi-step prompts may trail top-tier closed frontier models according to third-party evaluations.
- •Output token pricing is steeper than some open-weight rivals, making high-volume generation more expensive.
- •Not an uncensored model — safety filters and standard refusals still apply.

Sparse 80B/3B MoE with hybrid attention — extreme throughput for 256K contexts at a mid-tier price.
What is it good for?
- •Long-document analysis, summarization, and RAG across 256K token contexts.
- •Agentic automation with function calling, web search, and structured JSON output.
- •Code generation and repository-level understanding leveraging the large context window.
- •Cost-efficient large-scale inference where open weights and data sovereignty are required.
- •High-throughput batch processing of long-context tasks thanks to sparse activation.
Prompting tips
- •Feed full documents or extended conversation histories into a single prompt to exploit the 256K context window.
- •Use structured JSON schema output for reliable data extraction and downstream pipeline integration.
- •For coding, include relevant file context and imports to help the model reason across long dependencies.
Frequently asked questions
Qwen 3 Next 80B is Alibaba's open-weight sparse Mixture-of-Experts language model with 80 billion total parameters and 3 billion active per token. Released in September 2025, it uses hybrid attention and multi-token prediction to deliver high throughput across contexts up to 256K tokens.
On Venice, Qwen 3 Next 80B is billed at $0.35 per 1M input tokens and $1.90 per 1M output tokens. You pay only for the tokens you use with no subscription required.
Yes. The weights are released under the Apache 2.0 license on Hugging Face, Kaggle, and ModelScope. You can self-host, fine-tune, or run it privately through Venice's hosted inference.
Yes. On Venice, the model supports function calling, web search, and structured JSON schema output, making it suitable for agentic workflows and data extraction.
Qwen 3 Next 80B offers a larger 256K context window and a sparse 80B/3B MoE architecture optimized for ultra-long contexts. DeepSeek V3.2 is cheaper per token but uses a dense architecture and a 160K context window. Choose Qwen for long-document workloads and DeepSeek for cost-sensitive, shorter-context tasks.
It uses a sparse Mixture-of-Experts design with hybrid attention combining Gated DeltaNet and Gated Attention, plus Multi-Token Prediction. Only 3 billion parameters are activated per token, enabling high efficiency despite the 80 billion parameter total.
Venice runs Qwen 3 Next 80B under a private zero-retention tier. Your prompts are not stored, profiled, or used for training, and no account history is built from your generations.
