scaling01 · x · 2026-08-20

Based on inference speeds shared by Cerebras, an analysis using GPT-5.6-Pro estimates GPT-5.6-Sol at about 1.5 trillion total parameters (48B active), with an upper range of 2.5 trillion if highly sparse. The author notes that if true, this scale is already matched or exceeded by existing Chinese models like Kimi K3 (2.4T) and Qwen 3.8 (2.8T).
