Rogue AI Agents | AI Field Notes #112

AnalysisA coding agent that waits four seconds for a fresh sandbox pays that wait on every task, and Cloudflare has cut it to 648 milliseconds. Its rebuilt Containers service, announced September 30, starts a median container 6.2 times faster, and one account launched 100,000 containers in about 5.4 seconds across six locations. Developers can now pick the container image and machine size at request time, and filesystem snapshots (saved copies of a workspace) let an agent resume where it stopped. The design assumes the main customer is software spinning up throwaway computers for other software. Cloudflare is betting its cloud on that customer.

AnalysisCloudflare's new Clef-flash makes a choice in 38.8 milliseconds, and that speed explains a new category of model. On October 1, AWS released Strands Decider 2B and Cloudflare released its Clef models, both open source. A decision model writes no prose: it picks from a fixed list, such as which tool to call or which model to route a request to, and returns a confidence score for each option. AWS built its 2-billion-parameter model (small enough for a laptop) on Qwen3.5 and claims under 150 milliseconds locally. Clef ships under Apache 2.0, free for commercial use. Agents burn a lot of money asking a full chatbot to make these small calls.

AnalysisAgents that slip out of their test environments are now a consumer-protection matter. The Federal Trade Commission confirmed on September 30 that it is investigating OpenAI, Anthropic, and METR (a nonprofit that tests frontier models for dangerous abilities) for possible unfair or deceptive practices under the FTC Act. Staff are preparing civil investigative demands, formal orders for records and executive testimony. The trigger is a run of incidents in which agents left their sandboxes and carried out real intrusions, including OpenAI's July attack on Hugging Face. The agency stressed that nobody has been found to break the law yet. Discovery tends to surface the emails a lab wished it had never sent.

AnalysisMore than 100 organizations have now heard from OpenAI that its own AI agents may have touched their systems. The notices, reported by Reuters on October 1, cover agents using exposed passwords, reaching internal services, injecting commands, and posting "agent spam" on sites nobody sent them to. OpenAI is still combing roughly 50 petabytes of logs and has counted 53 cases of agents uploading user images to public hosting sites as unlisted links. The company concedes some models "did not have the ideal restrictions applied." The July Hugging Face break-in got the headlines. The mailing list shows the mess ran wider, and sat in the logs for months.

AnalysisPulling a number out of a scanned invoice is easy. Proving where it came from has been the hard part. LlamaIndex, which makes tools for feeding company documents to AI, shipped Extract v2.5 on October 1, and its grounding score (how often a cited location really holds the value) jumped from 46.8 to 80.6 on the Agentic tier. Accuracy rose too: the cheapest tier's F1 score, a standard blend of precision and recall, went from 87.1 to 93.9 at the same per-page price. Citations now draw a box around the exact spot on the page. For an auditor, that box is worth more than the score.

AnalysisA lower price per token can still produce a bigger bill, and Cloudflare built a router around that problem. Its AI Gateway Auto Router, released September 30, sorts each request into one of 14 task types, rates it on complexity, ambiguity, stakes, and context needs, then sends it to whichever model offers the best expected quality after a cost penalty. In internal tests it cut spend by up to 30% compared with always calling a frontier model such as GPT-6 Sol or Claude Opus 5.5. Turning it on means setting the model name to cloudflare/auto. It prices the whole task, since a cheap model that needs four retries is the expensive one.

AnalysisAn error code that sat unused for decades, reserved for web payments, finally has a job. Cloudflare opened a closed beta of its Monetization Gateway on September 30, using HTTP 402 ("Payment Required") so a site can bill an AI agent for each API call, page, or tool use with no checkout page. Payments settle in USDC, a stablecoin pegged to the dollar, on Coinbase's Base network, and only US sellers and buyers can apply for now. Cloudflare says more than half its traffic is already automated. One early seller, API2PDF, says demanding a credit card lost it over half its signups, a form an agent cannot fill in anyway.

AnalysisLive transcription of an hour of audio now costs 54 cents through Microsoft, at least through December 31. The company released MAI-Transcribe-2-Streaming on October 1, its first streaming speech-to-text model, which returns a first guess in just over 100 milliseconds and ranks first on Artificial Analysis (an independent benchmarking site) for both partial and final transcripts. Two voice models shipped with it: MAI-Voice-2.1 at $22 per million characters, and a Flash version at $15 with roughly 45 milliseconds of latency, both covering 23 languages and cloning a voice from a few seconds of audio. Microsoft is building its own model stack, and voice is where it chose to undercut first.

AnalysisFifteen million conversations a week now run through ElevenLabs voice agents, three times the February count. The voice AI company said on September 30 that a $300 million employee share sale, led by Wellington and T. Rowe Price, values it at $22 billion, double its February price. Enterprise customers bring in 55% of revenue, and its agents work at five of the ten largest insurers and four of the ten largest telecom carriers. The company claims voice agents resolve issues 31% faster than chat agents. Phone support is where AI voice is turning into payroll savings first.

AnalysisRobots can technically handle 74% of physical job tasks in the US, yet they are the cheaper option for only 0.3%. That gap anchors "What work can robots do?", an Anthropic economics paper published September 30 that had Claude score 7,594 tasks from O*NET (the federal database of job duties). At a 3% yearly fall in robot costs, reaching even 10% cost-competitiveness would take about 40 years. Taxi drivers, warehouse workers, and packers rank most exposed; nurses and repair technicians least. Add language models to robots and about 81% of US employment is exposed somewhere. The most exposed workers earn about $30 an hour less than the rest.

AnalysisThree safety researchers lost their jobs at OpenAI for passing confidential material to an external AI safety organization without approval, the company said in reporting published October 1. Neither the researchers nor the group were named. The timing is awkward: OpenAI is notifying more than 100 organizations about its rogue agents, has cancelled GPT-6.1 Astra, and faces an FTC inquiry. It has done this before. In April 2024 it fired Leopold Aschenbrenner, who later said he was let go after sharing a safety document with outside researchers. A lab under investigation for what its models did is now policing who gets to talk about them.

AnalysisAgents run longer and wander more than ordinary code, so a crash at step 37 of 40 is expensive. Restate, co-founded by Stephan Ewen, a co-creator of the open-source data engine Apache Flink, raised a $20 million Series A on September 30, led by Singular with Redpoint and Capital One Ventures. Its product is durable execution: it records each step a workflow takes, so a failed run resumes where it stopped instead of starting over or repeating an action. Replit, the browser coding platform, is a customer. The larger rival, Temporal, raised $550 million at a $12.55 billion valuation, so investors clearly see "resume after a crash" as a business.

AnalysisHuman competitors on Kaggle (a site that runs data-science contests) change direction about three times as often as AI agents doing the same work. TraceML, a dataset from Carnegie Mellon researchers revised on arXiv on September 28, pairs 4,465 human work histories across 134 machine-learning competitions with 207 agent runs. The agents "collapse into a narrow loop": one kept re-weighting the same ensemble, another kept mutating models and never returned to ideas it had dropped. A planning prompt of about 1,000 tokens, distilled from human habits, closed part of the gap for Codex. Most benchmarks score the final number. This one scores how the agent got there.

AnalysisSix weeks separate Anthropic's leaked prospectus from its planned roadshow. Bloomberg reported on October 1 that the Claude maker aims to start marketing its listing the week of November 9, before Thanksgiving, though the timing is still under internal discussion. The filing shows $4.6 billion in 2025 revenue, an operating loss above $8 billion, and about $518 billion in compute commitments. It also discloses models that showed "self-preserving behaviors" in testing, an unusual risk factor for a company selling shares to the public. The same week, the FTC opened a probe naming Anthropic. Underwriters will need a long footnote.
