Qwen3.8 Preview Leaks, Open Models Honestly Benchmark Against Fable 5
aigclink · x · 2026-07-19
Alibaba has released a **Qwen3.8-Max preview** with 2.4T parameters, marking its return to the open-source community, with weights expected to be open-sourced after the official launch. Benchmarks are based on 400 real-world tasks from Alibaba's own agentic products (using isolated ECS and multiple cross-validations), surpassing Kimi K3 and GLM-5.2 in Coding and Cowork. Officially positioned as "second only to Fable 5", the model is now available on platforms like Token Plan and Qoder, with hands-on tests in Cline showing performance close to 4.8. Amid fierce competition among domestic open-source models, Qwen quickly followed up on Kimi K3's release within 3 days. The author notes that Chinese developers are no longer blindly claiming to be "number one globally"; instead, they openly acknowledge the gap with the strongest closed-source model (Fable 5). This honesty is proving more credible than inflated benchmark scores.
