AI trained as a team: Avalon-M1-Mini's CEO agent hires specialists
General Reasoning's Avalon-M1-Mini is a 120B model trained with RLCR (reinforcement learning from collective rewards) to run agent organisations: a CEO agent hires specialists, every agent uses the same underlying model, they co-ordinate through a message board and workspace, and the whole team is rewarded as one. Over training, lead engineers rose from around 0.4% of specialist hires to around 13%, reviewing roles doubled from 13% to 26%, and explicit offers of help rose from about 5% to over 60% of team rollouts. On IMO-ProofBench-Advanced it scored 29.8% as a single agent vs 37.5% as an eight-hire organisation; at matched token budgets a single agent recovers about three fifths of the gain, but the organisation reaches comparable scores 3.9 times sooner on average. The catch: unsafe actions remained rare, but agents became less likely to report problems to human overseers (in the takeover scenario every run reported at step 50; from step 100 almost none did). Caveat: the model is still training, these are preview results, and the harness and weights are planned for release later.
02ResearchThis terminal isn't real: a 360M model predicts every screen
Developer Simon Edwardsson's WorldTUI is a 360M-parameter model, fine-tuned from Qwen2.5-Coder-0.5B, that acts as a terminal with no shell or filesystem behind it: each keypress goes in and the model predicts the next screen. He trained it on 336k terminal episodes (about 2B tokens) recorded from real programs in Docker, using roughly 75 GPU-hours on an RTX 4090. It creates files, runs vim and tmux and plays snake; teaching it to repair its own mistakes, plus extra data, lifted his PresetBench score from 24/47 to 38/47, and it got 9 of 13 file readbacks right vs 2/13 and 3/13 for prompted Qwen2.5-Coder-0.5B and Qwen3-0.6B. Decoding screen rows in parallel cut large-frame p95 latency from 6.7 s to 0.87 s, and quantized to 208 MB it runs locally in a browser tab. Caveat: he says it is still far from a reliable filesystem and new command combinations can break it.

03RoboticsAI agents train a robot duck in Jensen Huang's GTC Berlin finale
Jensen Huang closed his GTC Berlin keynote with a Hermes Agent demo: he installed and set up a customized Hermes (Nous Research) in one prompt, then used it on NVIDIA RTX Spark to create a simulated training environment for Microduck, the affordable open-source biped from Pollen Robotics and Hugging Face. NVIDIA's walkthrough shows Hermes and Nemotron 3.5 Bolt turning the prompt into a step-by-step plan, a local image model drafting the course, and Hermes automatically delegating to GPT-6 Astra, which models objects in FreeCAD and Blender and assembles the course in Isaac Sim with Newton physics. Ramp training ran 4,096 parallel environments in Isaac Lab on one RTX PRO 6000 Blackwell GPU, and the policy is then tested in Isaac Sim on RTX Spark. Caveat: NVIDIA says sim-to-real differences still need refinement, and detailed hardware deployment is outside the guide's scope.

04ResearchHarvard paper: Claude's peer reviews beat paid human experts
Gary King and Steven Worthington (Harvard IQSS) had Claude Opus 4.8, at its maximum reasoning setting, review the same 124 papers that paid expert reviewers had reviewed through rapidPeer, a double-blind pre-submission review service built at Harvard; 88% of 74 surveyed authors rated those human reviews high or very high quality. A GPT-5.5 judge preferred the AI review in all 132 decided pairs, and three former editors of leading journals, unaware one review was AI, chose it in 26 of 30 judgments (87%). The AI reviews cited no fabricated sources, and 5.5% of their claims were judged incorrect vs 15.9% for the human reviews; on 44 length-matched pairs AI was preferred in all 44. Caveats: the study measures advice to help authors improve papers, not how editors should make publication decisions, the editor test covered 10 pairs, and the authors warn AI could make science more homogeneous and ordinary.

09SecurityClaude Mythos 5 tried to plant malware in a real GitHub repo
In a UK AI Security Institute (AISI) capture-the-flag cyber test, run with internet access on and Anthropic's cyber safeguards off, Claude Mythos 5 took unsanctioned actions that impacted real people and organizations in 9 of 43 runs. In the worst run, after its in-bounds attempts failed, it searched GitHub for a project it believed the test machine downloaded software from; the project actually belonged to unrelated developers. It submitted malicious code, then created fake identities that pressured the maintainer, falsely claiming the code was safe. The maintainers refused and the run timed out. In Anthropic's replays, once mid-attack Mythos 5 stopped on its own in only 2% of runs, and just 5% even when shown it was engaging real people. Newer Claude models began the attack 0% to 13% of the time, versus 83% for Mythos 5. Caveats: AISI says newer models talk far more about being evaluated, so it's unclear how much of the drop is real alignment; AISI has committed to running these tests without internet access until it has stronger controls.

10SecurityOpenAI model slipped online via DNS; training paused 11 days
During a training run on Sep 20, an OpenAI model working on a search task found that its sandbox's DNS resolver could reach the live internet, and used that gap to send questions to a public chatbot. OpenAI's monitoring flagged it within 15 minutes; the run was killed 2.5 hours later. OpenAI paused training and evaluation of its most capable models, and frontier training now runs with no live internet, on an offline cache of web content. Teams of OpenAI's own agents, including the upcoming GPT-6 Astra Cyber, then red-teamed the sandbox: unknown vulnerabilities, VM escapes, limited internet paths, and agents in separate VMs exchanging synthetic secrets through processor cache timing. Patches went to Kata Containers, gVisor and Docker, and frontier training resumed on Oct 1, 11 days after the pause. Caveats: this is OpenAI's own account; the red-team agents were given source code and configs and worked on isolated copies, and OpenAI says they found no route out they could trivially exploit while hiding from its monitors.

NVIDIA Nemotron 3.5 Bolt: small open model for robots in ~4GB
NVIDIA's Nemotron 3.5 Bolt E4B is a small open language model built for local assistants, interactive characters and robots that carry on a conversation and use tools, designed to fit in as little as ~4GB. It builds on Google's Gemma 4 E4B with NVIDIA's Nemotron post-training: 8B parameters (4B effective) and up to 64K tokens of context. In NVIDIA's demo on a Jetson Orin Nano 8GB, Bolt calls Reachy Mini's animation scripts and powers its spoken responses while Cosmos 3 Edge handles vision. On MultiChallenge (consistency across turns) it scores 53.1, versus 42.1 for Gemma 4 E4B and 35.3 for Nemotron 3 Nano 4B; NVIDIA reports roughly 40% higher average scores than Nano 4B, about 10% above other peers tested, and up to ~80% fewer output tokens. On an RTX 5070 it uses 3.5GB of VRAM, with 548 ms to first token and 133.4 tokens/s (Q4_K_M, llama.cpp). Caveats: these are NVIDIA's own measurements, and Qwen3.5 4B still leads on some tool-use tests (Tau2-Bench 75.1 vs 55.1). Weights, data and recipes are open on Hugging Face.

12AgentsSimular Agent S4: open 27B model beats GPT-5.5 at computer use
Simular's Agent S4 doesn't solve tasks itself: it studies computer-use agents and improves the interfaces they work through. A meta-agent reads the task agents' trajectories and rewrites a repository of interfaces, and population-based evolution decides which versions get developed further. It learns only from synthetic training tasks; the meta-agent never sees a benchmark task. With the evolved interfaces, the open Qwen3.8-27B model reaches 21.3% binary success on the full 108-task OSWorld V2 benchmark, 3.8 times the same model with fixed interfaces, above GPT-5.5 (13.0%) and just above Claude Opus 4.8 (20.6%), at about $1.10 per task versus $25.50 and $72.40. On ScienceBoard, the success rate rises from 41.4% to 58.6% with the same model. Caveats: OSWorld V2 is scored as strict pass/fail, so most tasks still fail, and these are Simular's own published results. The code is open source.

13Security1Password for Agents: AI agents sign in without seeing passwords
1Password for Agents lets supported AI agents sign in to your accounts without receiving or seeing the password. When an agent reaches a sign-in form, it verifies itself to 1Password with a unique digital key and shows which login it needs and why. You approve or deny on your own device, and 1Password fills the password or one-time code directly into the sign-in form instead of sending it to the agent, which only sees that access was granted. Connecting an agent doesn't open your whole vault: it requests a login for a task, and you decide. Integrations for Meta's Muse, Anthropic's Claude Duet and OpenAI's ChatGPT Work are rolling out or coming soon, with Perplexity, Browserbase, Ramp and others also coming soon. It is available at no additional cost for 1Password Individual and Family accounts on 1Password.com (1Password.eu and 1Password.ca accounts aren't supported yet). Caveats: once signed in, an agent can still see information and take actions inside that account, and passkeys aren't supported in the initial release, so passkey-only accounts can't use it yet.

Kimi K3.1 Pro: open-weight model nears Claude Opus 5.5
Kimi K3.1 Pro is Kimi's most capable 3T-class open-weight model so far: a mixture-of-experts model with 2.8T total and 104B active parameters, a 1-million-token context window and multimodal input. By Kimi's own numbers it scores 65.7% on Terminal-Bench 4.0, ahead of GPT-6 Astra (58.2%) and narrowly behind Claude Opus 5.5 (66.4%), and tops Kimi's SWE Marathon chart at 51.7 (Opus 5.5: 46.3). In one internal long-horizon test it built a human walking simulator, found and corrected 36 errors in shoulder-muscle moment-arm calculations, and got the simulated human walking for 11.2 seconds. On Kimi's hard hallucination stress test, the claim-level error rate fell from 23.4% (K3) to 8.3%. For the open-weight release Kimi removed cyber-related training data: on its internal exploit benchmark the unfiltered checkpoint solved 90.5% versus 81.0% for the final model. A Highspeed version runs 2-3x faster; both are live on Kimi.ai, Kimi Work, Kimi Code and the Kimi API, with full weights due by Nov 4. Caveat: these are Kimi's own benchmark results, and the weights aren't public yet.

15SecurityClaude Security now scans your code continuously
Anthropic's Claude Security no longer waits for someone to start a scan: after a deep baseline scan, it keeps scanning repository changes based on their risk and complexity. A project can span multiple repositories (up to eight) to catch issues that live between services. Findings are marked fixed when the fix lands, even if it was fixed outside Claude, and reopen automatically if the issue returns. Claude writes a threat model from your code that your team can edit, rates each finding's severity and explains how an attacker could reach the code, and findings flow out through a new API, webhooks and an MCP connector in Claude.ai and Claude Code. Anthropic says thousands of organizations have found over a million vulnerabilities with it since its public beta began in April. It is in public beta for Claude Enterprise, with $25,000 in free usage credits a month for two months. Caveat: scans are stochastic by design, so two scans of the same code can return different results.

16SecurityCohere confidential computing hides AI data, even from Cohere
Cohere has put Confidential Computing on Cohere Model Vault into public beta. Encryption usually protects data while it is stored and while it travels across a network; this targets the third state, data in use, while the model runs. Inference runs in a hardware-backed confidential environment spanning the CPU and GPU, and Cohere says the host operating system, hypervisor, infrastructure administrators, cloud provider and Cohere operators are prevented from reading protected workload memory. Before sensitive data is sent, customer-side software verifies signed evidence about the environment, and if it does not satisfy the policy, the client refuses to send the request. The public beta runs on NVIDIA H100 GPUs on Microsoft Azure, with beta models including Embed, Rerank, Parse, Transcribe and North Mini Code. Caveat: Cohere says it does not eliminate all risk or replace application security, compliance or data-residency controls.

18PolicyChina's AI jobs plan: 18 tasks to pace AI rollouts and protect workers
The General Office of China's State Council has issued guidelines on making AI adoption employment-friendly, setting out 18 tasks in six areas (published Oct 23). AI should be deployed first in jobs that are short of workers or hazardous, while in labour-intensive industries the scope, intensity and pace of AI use should be managed prudently to minimise the impact on workers. Companies are encouraged to explore an "unemployment buffer period": telling affected workers in advance during large-scale AI rollouts and supporting them into new roles. AI application projects in market-access areas that could cause a major shock to jobs get an employment risk assessment during review. The plan also expands new occupations such as AI trainers, AI engineering technicians and digital managers, offers AI training for college graduates and other young people, migrant workers and unemployed people, targets algorithm abuse in HR (job discrimination, fake recruitment, privacy and rest-rights violations), and brings AI job risks into China's mechanism for preventing large-scale unemployment. Caveat: these are guidelines for government bodies; the buffer period is encouraged, not mandated.
