    Claude Mythos 5.2 predicted the complete AAV coat structure

    Claude Mythos 5.2 predicts the complete AAV capsid structure, which is composed of 60 identical protein chains. It writes code for an open-source folding model to handle the overlap grouping of adjacent five chains, then uses the symmetry of the capsid to assemble the 60 chains. On AAV2, its prediction deviates from the experimental structure by about the width of an atom.

    Why it matters: The original text provides specific methods and accuracy of the model in real scientific research tasks, allowing readers to judge its applicable boundary in structural prediction work.

    LangSmith has launched the public beta version of LLM Gateway, providing runtime control for production agents.

    LangSmith LLM Gateway has entered public beta, serving as a centralized governance layer between agents and models, uniformly executing spending limits, rate limiting, model fallback, and sensitive data deidentification. Spending and rate limiting can be set at four levels: organization, workspace, API key, and user. When the limit is hit, the agent receives a 402 response; fallback rules can take effect uniformly across models and hosting providers.

    Why it matters: The original text listed the specific control levels of the gateway in terms of cost, rate limiting, fallback, and data masking, which can help determine at which level the governance of the production intelligent agent should be placed.
