LLMs are making formal software verification feasible at a much larger scale (23 minute read)
We need ways to prove that code is free from bugs. Formal software verification, which could provide this guarantee, has always required years of expert effort, but LLMs can now produce formal proofs at large scale. This enables new software development workflows that include proven security guarantees. Formal verification will likely become an essential part of secure software development as model capabilities continue to improve.

Anthropic builds its own source control system (15 minute read)
Anthropic employs around 3,500 staff, but its coding output is closer to that of a company with 35,000 to 70,000 staff.

Mathematics seems to be a field where the outputs are celebrated less as examples of subjective expression and more as advancements in knowledge and understanding. A mathematician's work may be informed by their experience, but that's not what gives their contributions value. Mathematical knowledge remains objectively true whether it is observed by humans or sea sponges or computer programs.
