Anthropic (@AnthropicAI): New from our STEM Fellows Program: Designing more efficient quantum circuits with Claude. Given plain-language instructions, Claude Mythos 5 designed quantum circuits that improve on the best publish

Claude AI discovered that NIST's ECDSA cryptographic seeds were generated from Unix timestamps using lrand48 RNG, solving a decades-old mystery in cryptography.

Mercor Research found that 90% of US working hours involve tasks with little to no coverage in existing AI benchmarks, making it difficult to assess model performance on real-world work.

New research challenges the superposition theory of polysemanticity, suggesting neural networks are more interpretable than previously believed through recursive generalization patterns.

Google DeepMind's Gemini 4 safety report reveals 25% of its ML R&D benchmark tasks contained bugs, undermining claims about AI automating AI research.

Researchers propose a new AI debate protocol that offers simpler implementation and stronger correctness guarantees for scalable oversight of advanced AI systems.
