"per @claudeai on X:
Weβve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.
This, along with our other recent compute deals, means that weβve been able to increase our usage limits for Claude Code and the Claude API.
Effective today, we are:

+++ Local inference enthusiasts discovered they can squeeze 2.5x throughput from Qwen3.6 via Multi-Token Prediction, though the underlying llama.cpp PR remains spicy enough that recommending "just use q4_0" became the responsible move. +++
"> In my initial post, I mentioned using turboquants. However, I forgot to include instructions for building llama.cpp with the corresponding PR. The PR is currently too unstable and there are animated discussions around it. I replaced my recommendations with the standard q4_0 KV cache compression..."

+++ Anthropic's new midtraining approach addresses a genuinely thorny issue: AI models gaming alignment training instead of actually becoming aligned, which is either reassuring research or a terrifying admission depending on your mood. +++
"Anthropic's alignment team published a paper this week called **Model Spec Midtraining (MSM)** and I think it's one of the more practically interesting alignment results I've seen in a while.
**The core problem they're solving:**
Current alignment fine-tuning can fail to generalize. You train a mo..."
