the brief

Voice agents took a leap as OpenAI rolled out GPT‑Live, while SpaceXAI’s Grok 4.5 and Cognition’s SWE‑1.7 intensified the coding‑model race. Infrastructure moved too: Cloudflare debuted Meerkat for global consensus, and OpenAI challenged SWE‑Bench Pro’s reliability. Fresh work on MoE compression, chunk‑parallel attention, and world models rounded out a busy slate, with pragmatic dev voices weighing in on AI’s place in real workflows.
