AccBalanced · x · 2026-08-03
Alibaba's upcoming open-weights model Qwen3.8-Max (2.4T-parameter MoE) reportedly delivers frontier-level performance at a fraction of the cost.
- Autonomous Coding: Capable of self-evolving development for 10+ days without hand-holding, utilizing an issue -> code -> test -> repair -> merge loop to generate hundreds of commits and PRs.
- Aggressive Pricing: Priced at $2/M input and $6/M output tokens, representing roughly an 80% and 88% reduction in output costs compared to GPT-5.6 Sol ($5/$30) and Claude Fable 5 ($10/$50), respectively.
- Open Weights: Official sources confirm that open weights for both Qwen3.8-Max and the 27B version will be released next week.
