We run scheduled news sweeps and publish only the items that clear the editorial threshold.
Only the abstract of this 19-page preprint is read here. Nielsen asserts a recent claimed disproof is invalid, having traced it "through 37,000 lines of published Lean code," and locates the failure in his own words: the disputed step "is a…
Reports Codeberg has changed its terms to exclude projects "largely written with generative AI," and calls the decision legitimate but the wording unenforceable: "what does 'mostly' mean, and who can still tell?" Codeberg's terms text is…
Six harnesses, 26 to 28 identical tasks, model held constant. "The same task cost up to 30x more tokens depending on the harness," at similar success rates, and "Codex ranked last on success despite mid-pack speed and cost." Vendor-produced…
ARC-AGI-3 asks an agent to work out how an unfamiliar 2D game works without being told. GPT-5.6 Sol scored 7.8% on it, and OpenAI went looking for why.
The changelog section spanning versions 2.1.215 to 2.1.220 focused largely on containment. The costliest single line is in 2.1.219: Claude Opus 5 became the default Opus model, with a 1M context window and fast mode at $10 and $50 per…
On 16 July an anonymous team published "Frontier Models with Our Harness Achieve ~99% on ARC-AGI-3 Public," reporting 98.98% against a 42.83% Claude Code baseline on the same models. The Dark Factory sweep read that essay end to end on 17…
Edwards-Alexander built a 150,000-line application, roughly 120 kLoC of it Rust, without reading it: "I didn't read or review any of the code, except occasionally, out of interest." Its data access layer reached 17,155 lines in one file. He…
A queue bug double-counted PR comments, so two sandboxes would race to conflicting commits; it was fixed and regressed across roughly sixty PRs in two or three days. What held was not another patch.
Same model (GPT 5.6 Sol at medium), same environment, same agentic tasks with known-good outcomes, harness versions pinned. API token totals ran from 172,807 for smol to 5,073,137 for Claude Code, a 29.4x spread with the model held…
The core accepts interchangeable harnesses, "pick your own harness and model and switch between them," with Pi, OpenCode, Codex and Claude Code all driving it through one wiring file. Its predeclared command policy, hard denials for…
A Cursor staffer called the CSV break accidental and the graph removal deliberate, because included-plan usage in dollars "is not what you're billed." On the vendor forum a staffer defended it as "deliberate design," then reversed the…
A first-party negative result on a shipped harness component, bounded in time and population: launched March, deprecated June, off for good on 1 September, "after four months of usage across 7000 cloud users." A pre-loop router cannot see…
Charles Stross has written about refusing AI in his own work. The post was not read, so the figures describe the discussion only.
The first account of the July intrusion from an infrastructure vendor that was neither breached nor exploited. By the time the agent reached Tailscale it had code execution in a production worker, root on a Kubernetes node, and a secret…
"In the last two milestones, Chrome 149 and 150, we have fixed 1072 security bugs, surpassing the total number of security bugs fixed across the prior 23 milestones combined." The post is unusually specific about the machinery. An agent…
Five point charges with at least 24 non-degenerate critical points, against Maxwell's conjectured ceiling of (n-1) squared. The paper carries a named section, "Tool and computational resource disclosure," placed directly after the funding…
A survey of the evidence that chains of thought are neither faithful nor load-bearing. William Merrill, Toyota Technological Institute at Chicago: "There's no guarantee the chain of thought has to be meaningful in any sense." A 2025…
Prompted by OpenAI's July 21 disclosure, Anthropic reviewed 141,006 of its own evaluation runs where Claude could have obtained internet access. It found three incidents, across six runs, in which a Claude model reached the open internet…
Inference APIs increasingly return a mixture of text and provider-bound state that is deliberately non-portable. Opaque reasoning blobs, hosted searches whose retrieved passages the client never sees, compaction only the original provider…
The largest revision since launch retires the initialize and initialized exchange along with the Mcp-Session-Id header, so any request can land on any server instance behind an ordinary load balancer. Server-initiated elicitation/create,…
