  • Identical calls do not reliably recover identical structure, with mean node-set Jaccard from 0.39 to 0.96 and 72% of prompt-model cells never node-set-perfect.

  • However, although I was not using AI for my FOSS contributions, I kept using it at work.
  • In my workplace, as well as in many of my developer friends’, using AI to work is very, very common.
  • Not without a degree of shame, let me tell you about this experience, and how it was turning me dumber, lazy, and a worse developer.

Key details

  • A separable factorization makes each update scale linearly with the number of pixels, so the inference stays tractable at full image resolution, at a cost comparable to one $\Pi$GDM run.
  • FB-GDM requires neither the noise level nor the ground truth: its only inputs are the observation and the forward operator.

Makes your AI agent think like the laziest senior dev in the room.

Key details

  • The best code is the code you never wrote.
  • ~54% less code (up to 94%) · ~20% cheaper · ~27% faster · 100% safe Measured on real Claude Code sessions editing a real open-source repo (FastAPI + React), against the same agent with no skill.
  • ~54% is the mean across 12 feature tasks (Haiku 4.5, n=4); it reaches 94% where an agent over-builds (a date picker) and is near zero where the code is already minimal.
  • ponytail keeps every safety guard while a bare "write one-liners" prompt drops one.

Results & evidence

  • ~54% less code (up to 94%) · ~20% cheaper · ~27% faster · 100% safe Measured on real Claude Code sessions editing a real open-source repo (FastAPI + React), against the same agent with no skill.
  • ~54% is the mean across 12 feature tasks (Haiku 4.5, n=4); it reaches 94% where an agent over-builds (a date picker) and is near zero where the code is already minimal.
  • (The earlier single-shot benchmark reported 80-94% as a flat figure; against a fair agentic baseline that is the per-task ceiling, not the average.) Full writeup · reproduce it.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.

What's new

arXiv:2609.29505v1 Announce Type: new Abstract: Diffusion inference repeatedly evaluates the same large network.

Key details

  • We ask whether pretrained weights alone can identify residual branches that need not be recomputed throughout the trajectory.
  • Our \textbf{Spectral Concentration Ratio (SCR)} measures leading-versus-tail singular-value energy.
  • Combined with Frobenius magnitude, it yields an offline sensitivity proxy and a deterministic lifetime for each scheduled unit.
  • A frozen unit reuses its cached residual-branch update while the current residual stream and all external conditioning continue to propagate.

Results & evidence

  • arXiv:2609.29505v1 Announce Type: new Abstract: Diffusion inference repeatedly evaluates the same large network.
  • At matched layer-step budgets, SCR/Frobenius preserves quality better than random, depth, norm, stable-rank, and Frobenius--stable-rank schedules on LLaDA-8B, DiT-XL/2, U-ViT-L, and SDXL.
  • The complete captured-graph system reaches $2.8\times$--$3.0\times$ wall-clock speedup over eager inference.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.
