Mythos / Fable is unbelievable. Was on a customer call today and had Claude transcribing in the background. As they were telling me about the features they wish their current software had, Claude was building the features in real time. By the end of the call I was able to show a fully working product, with the exact workflow they mentioned 15 minutes earlier. Autonomous looped building triggered from a customer call. 🤯

While Mythos is changing the security threat model in some ways, I am not particularly concerned about exploits being found in blue-chip smart contracts. If the code base is small and important enough (most SC code is), then traditional methods are sufficient to achieve high confidence in security. What's changing is the cost of searching for exploits in large codebases. These bugs were always there, but we are compressing the time to discover them. This is largely what is driving the recent infrastructure compromises affecting everyone. With smart contracts, this can be protected against using rate limits and timelocks, limiting the damage that can be done if an off-chain system is hacked. Overall, this is a period of understandable apprehension, but I'm confident that by following best practises we can make it to the other side stronger than before.

anthropic hyped mythos like crazy but gpt "gpt-5.6 sol" already looks roughly on par with mythos 5, and "sol ultra" seems slightly ahead pricing also looks pretty competitive: sol: $5 input / $30 output terra: $2.50 / $15 luna: $1 / $6 dario single-handedly ruined the month

🚨TRUMP ADMIN CLEARS ANTHROPIC MYTHOS 5 FOR LIMITED ROLLOUT! After a two-week standoff and export controls that forced Anthropic to disable its top models, the Trump Administration has approved release of Mythos 5 to roughly 100 trusted companies and federal agencies. Senior Anthropic leaders met with officials in DC to resolve national security concerns.
