Kimi K4 Leak: Beat GPT-6 Astra and Sonnet 5.5. - Moonshot wants more Blackwell GPUs to train a model that could beat Claude Fable 5.1 and GPT-6 Astra. - K3 already sits at 2.8T parameters the largest open-weight model released so far. - No official K4 specs or timeline exist yet. - The catch: the White House has already accused Moonshot of routing Blackwell access through Thailand and of distilling Anthropic’s Fable into K3. - If the chip report is real, the open-weight gap narrows faster than expected. - No official date has been confirmed by Moonshot.
