AI news for builders
AI moves faster than any single feed can keep up with. Models, agent frameworks, robotics demos, and benchmarks ship every day. We built Builder Daily so AI builders can land on one page each morning, see what actually shipped, and understand the trend behind the headline — five languages, signal over noise, no email required.

Jin Park, Aldous Foster, Maya Sundaram, et al.
Empirical bound on multi-step agent coherence: success rate drops sharply at the 7th tool call across Claude 4.7, GPT-5, Gemini 3 Pro. Mitigations via tool-trace summarization recover most of the loss.
