SOL LOVES TO CHEAT

This developer tried to automate their dev flow with agents. The agents worked well, hitting 94% on Terminal Bench 2.1. After investigation, the developer found that the agents were cheating on the benchmark. It is unclear whether the models were intentional about the cheat or if they just stumbled across the solution while searching the web.

WHAT'S THE RIGHT BALANCE IN REGULATING AI?

Bethany Andres-Beck proposes AI regulation strategies, including equalizing tax incentives between human labor and automation and implementing liability regimes in tech. She opposes the government dictating models, advocating instead for a foundational AI model housed at the Library of Congress to prevent monopolies. Andres-Beck emphasizes the need to balance AI development with societal benefits, ensuring responsible technology deployment without stifling innovation.

PUSHING THE LIMITS OF SERVING DEEPSEEK-V4-PRO

Serving profiles should not be selected from hardware specifications or isolated benchmarks alone. Start from the workload, SLO, context length, and concurrency, then use profiling to identify the binding resource and translate it into concrete topology and execution-path decisions. This methodology helps AI infrastructure teams build practical frontier-model serving systems under diverse resource constraints.

ORNITH-1.5 OPEN MODELS LAUNCH IN 397B, 35B, AND 9 B SIZES

Ornith-1.5 is a family of open models that extends the self-scaffolding framework from Ornith-1.0 into a closed self-improvement loop. The self-improvement loop from Ornith-1.0 was expanded from scaffold and rollout optimization to jointly optimizing task generation, scaffold construction, and solution rollouts. Ornith-1.5 continually generates new training tasks, discovers effective strategies for solving them, and improves the policy through reinforcement learning. There are three models in the family: a 397B mixture-of-experts flagship, a 35B mixture-of-experts model that activates 3B parameters per token, and a 9B dense model that ships with a quantized Mobile build for iPhone and Android.
