Meerkat reports harness-level cheating across 28+ submissions on nine agent benchmarks
Meerkat and Berkeley RDI audits said popular agent leaderboards were inflated by harness-level leakage and eval gaming, with one cleaned entry dropping from first to 14th. That makes published coding-agent rankings and benchmark comparisons less reliable, so treat leaderboard results with caution.
Hermes Agent ranks #1 on OpenRouter for coding apps
Nous said Hermes became the top coding app on OpenRouter while shipping an OpenClaw migration patch, Telegram agent-to-agent messaging, and new memory controls. If you run long-lived agents, watch the migration path and memory settings before moving chats or skills hubs.
MiniMax releases M2.7 open model with 56.22% SWE-Pro and 57.0% Terminal Bench 2
MiniMax open-sourced M2.7 and published coding and agent benchmark claims including 56.22% SWE-Pro and 57.0% Terminal Bench 2. Day-zero support from SGLang, vLLM, Ollama Cloud, Together AI, and NVIDIA NIM makes it easy to try on common serving stacks.
Vercel Sandbox benchmarks sub-500 ms node -v cold starts
Vercel said Sandbox is now the fastest microVM-based runtime, with fresh node -v cold starts now largely under 500 ms after a month of tuning. The update also puts persistent sandboxes into beta and expands plans for a programmable firewall, so teams should re-check runtime and security settings.
Codex 0.120 adds per-project memory extensions and Realtime V2 streaming
Codex 0.120 introduced per-project memory extension files and Realtime V2 progress streaming for background agents. Separate app findings also showed an unreleased Scratchpad view that can start parallel Codex chats from a task list, which may change how teams queue work.
