Claude 3.7 is More Significant than its Name Implies (ft DeepSeek R2 + GPT 4.5 coming soon)

Claude 3.7 is here, hot on the heels of Grok 3 and a host of other developments, but how good is it really? And what does it say about the next few months in AI? I’ve read the papers, played with the model for hours, and benched it on Simple. Things aren’t slowing down. Plus the latest in humanoid robots, led by Helix and freaked out by Protoclone. And reports of GPT 4.5 and DeepSeek R2.
