Alibaba unveils Qwen3.8-Max, its largest AI model ever open-sourced
🧒 Discovery
Imagine a giant brain packed with billions of ideas that only uses a small part of them each time you ask a question, so it stays fast: that's Alibaba's new trick.
📰 Essential
Alibaba unveiled Qwen3.8-Max, a 2.4-trillion-parameter model that activates only 95 billion at a time and handles up to a million tokens of context, marking the Chinese group's return to open models at this scale.
🔬 Expert
The mixture-of-experts design, 95 billion active parameters out of 2.4 trillion total, aims for frontier-level power without paying the full compute cost on every query. By open-sourcing the weights instead of keeping them proprietary, Alibaba directly challenges Kimi K3 and DeepSeek in the Chinese open-model race, reversing a year of keeping its top models closed.
