GLM 5.2 Undercuts Opus, Self-Rewriting Harness, AI Out-Persuades Humans & Prompt Injection as Role Confusion

AI now out-argues expert human debaters, even coaching doesn't save them. Cap its word count though, and the entire edge drops to zero.This week: GLM 5.2 undercuts Opus, Xiaomi's self-rewriting harness, OpenAI's "jalapeno" chip, prompt injection as role confusion, and the clock ticking to 4:45.Co-hosts: Shimin Zhang, Dan Lasky, Rahul Yadav.▸ GLM 5.2 — Z.ai's open-weight 750B MoE: Sonnet-to-Opus quality at ~1/3 the cost (~$5 vs $20 a build). Semgrep even had it beating raw Claude Code on security.▸ Engineering jobs — SignalFire: software engineering was 2025's most resilient role (~55% of hires). Ramp: AI adopters grew headcount 10.2%, entry-level share slid 50%→34%.▸ Tool Shed — Xiaomi's Harness X uses an AEGIS judge to rewrite its own scaffolding (Qwen3 5.9B, +44% planning). Ornith 1.0 does RL on the weights and the solution together.▸ Hardware Hut — OpenAI + Broadcom's "jalapeno" inference chip: from the wafer photo, a systolic-array ASIC, six HBM stacks, cost-per-watt beating NVIDIA, ~9 months to tape-out.▸ Post-Processing — Hackenberg et al.: AI out-argues lay people (~8pp) and trained debaters (~4.6pp). Cap it to a human's word count and the edge hits 0.0pp. It tripled charity donations.▸ Listener Mail — Bloomberg on Silicon Valley engineers running a dozen agents at their kids' games. Dan's version is cognitive debt; ChainGuard wants managers at the 50th percentile of usage.▸ Deep Dive — Yu, Cui & Hadfield-Menell: jailbreaks are a model mistaking your words for its own thoughts. The "wearing green" trick breaks GPT-5-mini and o4-mini.▸ Two Minutes to Midnight — Masa Son doubts Musk's data-centers-in-space (~7% of the cost is electricity). OpenAI may delay its IPO toward $760B; Epoch AI sees capex outrun cash flow by Q3 2026.
