AI Engineer World's Fair Wave 2 and the Week Open Weights Got Loud

TLDR: AINews announces Wave 2 Call for Speakers for the AI Engineer World's Fair with new tracks for Autoresearch, Memory, World Models, Tokenmaxxing, Agentic Commerce, and Vertical AI. The same issue runs a long news roundup where Grok 4.3 ships at lower prices with mixed evals, DeepSeek V4 Pro lands as a credible open-weight coding agent, Codex keeps eating UX ground from Claude Code, and a wave of agent runtime work signals the bottleneck is moving from model IQ to harness design.
