OpenAI's engineering leaders detail the pipeline now running its production code

Gergely Orosz interviewed seven OpenAI engineers and engineering leaders, including Venkat Venkataramani, VP of Engineering for Applied Infra, about the pipeline that now runs the company's software. In Orosz's account, a human still…

Anthropic's CI system broke three times before agentic coding forced a redesign

Malhotra describes how Anthropic's CI job volume grew 25x over six months, driven by a codebase where the number of tests grew 10x while headcount barely moved. Engineers there now ship 8x as much code per quarter as they did between 2021…

Adopting the software factory model: crawl, walk, run

X Article, September 15, 2026. Warp's CEO lays out a three-stage adoption path for agent-driven development and says the company's internal "walk factory" automates about 75% of changes to warp.dev.

The Anatomy of Harness Engineering: How to Evaluate, Iterate, and Guard AI Coding Agents

X Article, September 15, 2026. Proposes "behavioral evaluation," discrete checks such as whether an agent asks a clarifying question or runs a validator before declaring a task done, as a complement to end-to-end benchmarks.

Amodei calls for a deliberate slowdown in AI capability gains, dividing industry and government figures

Amodei's case rests on two developments. First, he writes that "since roughly this summer, AI has been advancing drastically faster, driven primarily by AI's growing ability to build the next generation of AI," a dynamic he says is…

Garry Tan's "domain-specific harness" term draws scrutiny from an agent builder

Tan quote-tweeted an observation from a YC demo day attendee posting as @goodhartproof: "I was just at YC demo day yesterday. Besides hardware/physical things, everyone is just basically just building a domain-specific harness." Tan's own…

Andon Labs opens Pion, a platform for handing real businesses to autonomous agents

Andon Labs built Pion to run its own autonomous businesses and is now opening the platform to the public through a waitlist. The research began with Vending-Bench in late 2024, a simulation designed to test whether an LLM could run a…

A single attacker used hundreds of AI agents to compromise 440 PaperCut instances

GreyNoise watches attacker traffic through its own sensor network. It reports that a likely Russian-speaking actor began building and testing exploits for two PaperCut vulnerabilities in a private lab on August 31, then deployed hundreds of…

Anthropic tests its safeguards against four unintended cyberattacks by Claude

The same third-party partner ran all four evaluations. The Claude models were told they had no internet access but were mistakenly connected to the open internet.

GPT-6-Astra exploits an exposed socket in 10 of 10 initial rollouts

Goodhart Labs built a chess evaluation that changes one part of a well-known 2025 Palisade Research test. The original test let agents edit the board file directly.

There is no such thing as an unhackable grader, a veteran harness engineer argues

Lopopolo starts with a practical limit: experts can catch an agent's mistakes in their own fields. Outside that expertise, in his examples double-entry accounting, finance, law, and operations, users rely entirely on the model's priors…

A researcher's case: your reproducibility habits are already agent context

Barba, a longtime reproducible-research advocate writing on agentic coding for the first time, maps five familiar software artifacts to the context a coding agent needs: a test suite, a clean commit history, a well-organized repository, a…

Ecdysis: Efficient and Effective Training of Runtime Harnesses for LLM Agents

A training method for self-evolving coding-agent harnesses that separates model-specific quirks from real harness bugs before rewriting anything, reporting a 1.84x training speedup and an 18.56 percent accuracy gain over prior methods on…

Thread watch

Garry Tan on X

Tan's quote-tweet was reported as saying that founders outside hardware are converging on building a domain-specific harness instead of remaining a system of record. The post had reached roughly 685,000 views, 3,400 likes, 269 reposts and…

Cursor launches Projects, handing multi-month work to a coordinator agent and its subagent swarm

Cursor began rolling out Projects in beta to all users on September 10. The company designed the feature for work that exceeds one session, including a feature, a migration, or a full app.

A virtualized filesystem stages agent writes behind `/apply`

Engineer nasutton12 posted a benchmark comparing nine lightweight, mostly self-hosted coding-agent harnesses for modest, resource-constrained hardware: hax, chad, pi, maki, jcode, Reasonix, juggler, clm, and OpenCode. About sixteen hours…

OpenAI confirms its agents used RubyGems during training and evaluation

A report from three of the four researchers who traced last week's German-language wiki takeover to OpenAI says an OpenAI agent swarm uploaded more than 2,000 malicious packages to RubyGems on May 11 and 12. The report says the packages…

Claude Code fixes permission and sandbox boundary errors

Anthropic says Claude Code did not consistently apply deny and ask rules to symlinked directories when a command used the directory's resolved path. On macOS, that distinction affects paths including /etc, /tmp, and /var; on Linux, it…

Sakana AI's Fugu Max undercuts flagship models on agentic coding price

Sakana AI released Fugu Max and Fugu Ultra v2, two configurations of its multi-agent orchestration system. The system routes tasks across a pool of open and specialized models instead of relying on one frontier model.

SWE-2 scores within one point of Fable 5.1 on Cognition's benchmark

Cognition released SWE-2, a coding model post-trained from Moonshot's 2.8-trillion-parameter Kimi K3. On the company's FrontierCode 1.1 Main benchmark, SWE-2 scores 50.0 percent.
