AMAZON CEO'S TALKS WITH US OFFICIALS TRIGGERED CRACKDOWN ON ANTHROPIC MODELS

Conversations between Amazon chief executive Andy Jassy and US officials prompted the Trump administration to halt all foreign use of Anthropic's most capable AI models. Researchers at Amazon had used a series of prompts to get Anthropic's Fable 5 model to provide them with information that could be used to aid cyberattacks. White House officials asked Anthropic to fix the vulnerabilities or take down the model. Anthropic has shut down access to its Mythos and Fable models to comply, but says that the vulnerabilities flagged by Amazon are relatively basic and that other publicly available models are also capable of discovering them.

INFERENCE COST AT SCALE WITH NAPKIN MATH

You need the following information to work out the dollar price-per-user: GPU hardware specs, context length, active parameter count of the model, and product-specific factors. The specifics of the model architecture matter surprisingly little, unless it's something entirely different, like diffusion. This post shows how to work out the math on paper. The exercise should reveal how various optimizations in inference engines help SaaS products remain profitable.

TODAY'S FRONTIER AI COMPANIES WILL NEVER EXCEED THE AI CAPABILITY FRONTIER AGAIN

Networks of smaller AI models are outperforming every frontier AI system on speed, accuracy, and cost. Everyone in the 1960s was wrong about the mainframe computer, and everyone is now wrong about centralized AI. The future is a network of neural networks.

THE PHYSICS OF A FABLE

Rafa Schwinger reverse-engineers Claude Mythos and Fable by arguing the moat is not architecture but the environment foundry, with capability decomposing as base foundation times gradeable signal extracted on top, and verifiable reward becoming the scarce decisive input now that text and raw compute no longer are. The recipe stacks dense pretraining, GRPO-style verifier RL where reward-hacking soundness is the actual binding constraint, long-horizon process rewards with learned context-folding that beats million-token windows at 32K active, plus best-of-N test-time compute exposed as an effort dial.

KIMI K2.7 CODE (HUGGING FACE REPO)

Kimi K2.7 Code is a coding-focused agentic model that has stronger end-to-end task completion across complex software engineering workflows and improved token efficiency compared to Kimi K2.6. The Mixture-of-Experts model has 1 trillion total parameters. It can be accessed on Moonshot's OpenAI/Anthropic compatible API. The model works best with Kimi Code CLI as its agent framework.

INTRODUCING THE OPEN KNOWLEDGE FORMAT

The Open Knowledge Format is an open specification that formalizes the LLM-wiki pattern into a portable, interoperable format. It is vendor-neutral and agent- and human-friendly. The standard can represent the metadata, context, and curated knowledge that modern AI systems need. The specification uses familiar patterns with no complex compression scheme, new runtime, or required SDK.
