Estimates Suggest Claude Fable 5 Could Have 14.5 Trillion Total Parameters
imjustnewatai · x · 2026-07-26
A user speculates that Anthropic's Claude Fable 5 might have approximately 14.5 trillion total parameters.
This estimate is based on DeepSeek founder Liang Wenfeng's recent statement that America's largest model activates around 800B parameters per token. Assuming Fable 5 is this model and applying the active-to-total parameter ratio of DeepSeek-V3 (37B active out of 671B total), the math points to a massive 14.5T total parameter count. There are also rumors that Fable 5 and Mythos 5 share this underlying model.
