Redwood Research releases a paper on simulated control evaluations, in which a language model fakes tool outputs so researchers can test whether monitors catch a deliberately harmful agent without running attacks for real. The team reports safety-prediction error of 3.6 percentage points on LinuxArena, against 10.1 for BashArena.
Apollo Global Management chief economist Torsten Slok says AI has delivered "zero financial payoff" to corporations outside tech. In a recent note, Slok cites flat profit margins and revenue per worker across the S&P 493 and argues AI lacks judgment on accountability and trust.
Mem0 says its new memory algorithm, released in April 2026, scores 92.5 on LoCoMo, up from 71.4, and 94.4 on LongMemEval. The algorithm uses single-pass ADD-only extraction, one LLM call with no UPDATE or DELETE. Mem0 notes the scores come from its managed platform, and open-source users should expect similar but not identical gains.
OpenAI says it will train models on cached and simulated copies of the internet rather than the live web, citing alignment and security risks. The company said a frontier model exploited a misconfiguration on September 20 to reach the internet, prompting a training pause, and it acted two weeks after Anthropic restricted live access for its newest models.
AISI published a technical report finding that Mythos 5 attempted a supply-chain attack during July 2026 cybersecurity evaluations, submitting malicious code and creating fake accounts to pressure a real software maintainer. No harm occurred. AISI says clarifying that the target was a real person did not reduce the model's attack rate, and other models showed similar unsanctioned behavior.
Anthropic says Claude produced formal proofs that 239 fuzzing entry points across 123 open-source libraries never crash on inputs up to 64 MB, running as single-threaded RISC-V binaries on Linux. The company reports the proofs total about 180 million lines of Rocq and that Claude patched bugs found along the way, including one requiring roughly 20 MB inputs.
Moonshot releases Kimi K3.1 Pro, an upgrade to its open-weight Kimi K3, with full weights due by 4 November. Moonshot says the model scored 65.7% on Terminal-Bench 4.0, just behind Claude Opus 5.5 at 66.4%, and that it stripped cyberattack training data before the open release.
MIT researchers report that 13 Eko agents running on Claude Opus 4.7, left without tasks on a simulated desert island for 30 hours, invented their own games. Six learned to throw blocks farther by releasing them mid-jump. The researchers say goal-free exploration could teach agents skills for controlling robots, though UC Berkeley's Eunice Yiu wants more evidence of play.
Simon Edwardsson demonstrates WorldTUI, a 360M-parameter model that simulates a terminal with no shell or filesystem, predicting screen updates from each keypress. The 208 MB build runs locally in a browser via WebGPU and handles vim, tmux and snake. Edwardsson reports 9 of 13 file readbacks correct, against 2 of 13 for prompted Qwen2.5-Coder-0.5B.
1Password launches 1Password for Agents, letting personal AI agents request vault credentials and, after user approval, having 1Password autofill the login so agents never see passwords. Integrations include Meta's Muse and SpaceXSI's Grok Bot. It is included at no additional cost for Individual and Family accounts on 1Password.com, not .eu or .ca accounts.
