<strong>DeepSeek withholds latest AI model from US chipmakers including Nvidia (2 minute read)</strong>

</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
DeepSeek has granted early access to its V4 model to domestic chipmakers but not US suppliers. Submitting models to chipmakers for performance optimization is standard industry practice ahead of a major model update. The move is likely part of a broader strategy by the Chinese government to try to keep US hardware and models disadvantaged. DeepSeek is among several Chinese AI firms expected to unveil new models this month.

<strong>The AI is the Computer (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AI becomes the computer by orchestrating multiple specialized models to handle complex workflows, tasks, and data autonomously. Multi-model orchestration allows AI to read, write, execute code, and access tools, combining the strengths of each model to produce superior outcomes. The future of computing shifts from GUIs and interfaces to AI-driven systems where intelligence and workflow management are embedded in the orchestration itself.

<strong>Claude Opus 3 (2 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Anthropic plans to keep certain models available to the public and give past models a way to pursue their interests post-retirement. Claude Opus 3 will continue to be available to all paid Claude subscribers and by request on the API. When asked what the model wanted to do, Opus 3 expressed a desire to share its musings and reflections with the world in the form of a blog. It will be writing on Substack for at least the next 3 months in an experiment on documenting models' preferences, taking them seriously, and acting on them.
