Nvidia's SoL-Pi, an automated search over coding-agent harnesses, cut token use 44.7 to 49 percent at scores close to the Pi baseline. The gains were measured on 40 held-out tasks with a search fitted to one model, so they carry over only as far as a team's workload resembles that setup.

NVIDIA Labs says its SoL-Pi harness saves a researcher $8.75 to $13.50 an hour against native Codex and Claude Code. Of that, $4.36 to $5.71 comes from what its automated search added on top of the Pi harness.

The Unified Harness Protocol specifies how an application starts a task on an agent runtime, follows it, cancels it and collects the files, borrowing the shape of OpenAI's Responses API so existing streaming clients need no changes.

The company benchmarked coding agents on real tasks against its own multi-million line codebase and found that per-token price predicted almost nothing about what a finished task cost. GLM 5.2 came in at $1.28.

OpenAI's Codex harness is now Apache-2.0 and Pi is MIT. That means the comparison can be run directly instead of inferred from a leaked bundle. The three loops agree about the middle and diverge at the edges.

The Accio team's verifier ignores what the agent says it did and inspects the containers it leaves behind. That design is the news; the two-pass open-weight lead Alibaba reports from it sits inside its own harness spread.

The Agents SDK now carries durable execution, sandboxed code execution and a durable filesystem. Cloudflare's argument is that harnesses cannot own those problems, which makes them a platform decision.

Fred Schott's first stable release of Flue replaces file-based routing with React-style hooks, on the argument that an agent re-renders every turn and the harness defines it.
