智东西 · wechat · 2026-08-13

Alibaba's Qwen team open-sourced the weights for its flagship model, Qwen3.8-2.4T-A95B, featuring 2.4 trillion total parameters with 95 billion activated per token. It natively supports over 1 million tokens of context.

Capabilities & Benchmarks

The model excels in coding and long-horizon agentic tasks, topping the PaperBench and OSWorld benchmarks. However, it trails slightly behind GPT-5.6Sol and Fable5 on TerminalBench2.1 and SWE-benchPro. Qwen demonstrated the model's autonomous capabilities by having it code continuously for 16 days and manage a virtual e-commerce business.

Deployment & Pricing

The model defaults to a mandatory thinking mode. UnslothAI managed to compress the model from 4.9TB to 397GB using dynamic quantization, significantly lowering local deployment barriers. Overseas API pricing is set at $2 per million input tokens and $6 per million output tokens.
