VeriMoA's Intermediate-Language Detour Contradicts the Fine-Tuning Orthodoxy in LLM-Based Verilog Pipelines

VeriMoA routes specs through C++ and Python before Verilog, gaining 15-30% Pass@1 without fine-tuning and challenging whether HDL training pipelines are load-bearing.

VeriMoA's Python/C++ Relay Exposes a Structural Gap in LLM Hardware-Semantic Reasoning

VeriMoA routes spec-to-HDL through Python and C++ intermediates for 15-30% Pass@1 gains, yet simulation benchmarks miss synthesis failures that can emerge at tapeout.

DPrivBench Exposes a Blind Spot: LLMs Can't Reliably Verify Their Own Differential Privacy Guarantees

A new benchmark tests 11 LLMs on 720 DP verification tasks. Top models ace textbook questions — then fall apart on the algorithms that actually appear in production privacy code.

ml-intern's 32% GPQA Gain on a Single H100 Exposes the Assumption That Post-Training Still Needs a Human ML Researcher

ml-intern hit 32% on GPQA in under 10 hours, beating Claude Code's 22.99% on the same task — but a 51% instruction-tuned ceiling marks what the autonomous loop cannot close.
