Summary
Google Cloud AI Research has unveiled Harness², an open-source framework that improves agent performance by recursively optimizing surrounding environmental elements such as prompts and tools without altering model weights.
Key Points
- While keeping model weights fixed, Harness² manages eight harness components—including system prompts, guardrails, memory, and skills—as files, recursively modifying and optimizing them.
- To function even in open-world environments without ground-truth labels or verifiers, it introduces a two-stage recursive architecture consisting of Propose, Probe, and Compose.
- With just a single refinement step (k=1), it demonstrated performance improvements across all three tested benchmarks and four model-harness configurations.

Summary
An issue where the Codex Desktop app on macOS exhausts disk space due to an abnormally large number of pending dump files generated by a crash loop within the Crashpad error handler itself
Key Points
- While the Codex Desktop app runs normally, browser_crashpad_handler repeatedly crashes and restarts in the background, accumulating dump files at a rate of roughly one per second
- A Mach IPC error in the handler (mach_port_request_notification failure) combined with self-monitoring functionality causes continuous dump file generation, amounting to approximately 0.6 GB per hour and up to 15 GB per day
- Deleting files or reinstalling the app does not resolve the issue, and users are demanding fundamental fixes such as storage limits and rotation/cleanup policies for dump files
Notable Quotes & Details
Notable Data / Quotes
- 1 dump per second, approximately 15 GB generated per day
- Total of approximately 323 GB, 4.04 million files accumulated

Summary
A project that implements a KV cache for the GPT-2 model from scratch using PyTorch and compares theoretical savings against actual latency and memory measurements.
Key Points
- Confirmed that logit discrepancies with the Hugging Face implementation matched closely at around 6.1e-5, and verified cache concatenation ordering during single-token and multi-token decoding.

- Identified and accounted for an 8,519,688-byte discrepancy between theoretical memory (72 KiB per token) and actual measurements, showing it was due to the cuBLAS workspace and the next-token tensor.
Notable Quotes & Details
