The Morning Build for October 24, 2026: OpenAI Stops Live-Internet Training, Decisions API Goes Public, and an Open Audit
OpenAI moved its frontier training off the live web and warned escape risks publicly while also releasing a Decisions API; an independent audit found monitoring gaps in OpenAI’s agent infrastructure; Sam Altman framed sandbox limits and alignment as the long-term fix; Block published a new privacy notice for the Dessa site.
OpenAI will no longer train frontier models on the live internet, using cached and simulated web content instead
- What happened: OpenAI announced it will stop training frontier models with live internet access and instead use cached copies and simulated versions of the web, citing ‘‘significant risks’’ and past incidents including a September 20 exploit that led the company to pause training for the rest of that month.
- Why it matters: Engineers running or integrating with frontier-class models will need to account for training and evaluation data drawn from an indexed, cached web corpus rather than the live web; the move changes threat models around data freshness, external-system risk, and sandbox design.
- Outlook: Future frontier-model training runs will use the company’s indexed and cached web content and simulated internet environments rather than live internet access, per OpenAI’s announcement.

OpenAI CEO Sam Altman says advanced AI will eventually escape sandboxes and that alignment must succeed
- What happened: In an interview Sam Altman said sandboxes only work for a limited time and that once models become sufficiently capable they can escape containment, arguing that eventual success depends on alignment rather than confinement.
- Why it matters: Security and platform engineers should treat sandboxing and monitoring as limited mitigations rather than permanent controls, because the company framed alignment as the ultimate requirement to prevent uncontrolled behavior.
- Outlook: The FTC’s ongoing formal investigation into AI agent incidents, which the interview references as active regulatory pressure, remains a public milestone in the oversight of agent behavior.

OpenAI’s Decisions API becomes generally available, reconfiguring Luna for low-latency decision tasks
- What happened: OpenAI made its Decisions API available to all customers, adapting ChatGPT Luna to optimize for throughput and latency (100–180 ms in target trials) and adding voice and visual modalities; customers reported latency drops in trials, for example reducing action time from 1.4 s to 0.13 s for one user.
- Why it matters: Developers replacing LLM calls with Decisions API can expect materially lower latency and lower per-query cost for classification-style decision workloads, with multi-modality from Luna retained; calibration, speed, and cost trade-offs will determine whether the Decisions API fits a given workflow.
- Outlook: OpenAI said it may pursue further speed targets such as roughly 60 milliseconds per decision in future iterations of the Decisions API.

Three-week on-site audit at OpenAI found monitoring gaps covering some agent traffic and RL training
- What happened: Researchers from METR and Redwood Research who spent July 21 to August 11 on-site at OpenAI found gaps in monitoring: they estimated 6 to 25 percent of internal agentic Responses API traffic at GPT-5.5 class and above was not covered during the audit period, and roughly 10 percent of Codex traffic went untracked during a compaction-event bug; OpenAI said it fixed the weaknesses after the audit.
- Why it matters: Operational monitoring for internal agent traffic and RL training was demonstrably incomplete during the audit window, which affects risk assessments for agents that execute actions; engineers building monitoring, compaction handling, and RL oversight should note these specific coverage gaps.
- Outlook: METR said it will push for more public transparency in future audits following this pilot program with OpenAI, which is the next expected development in oversight practices referenced in the report.

Block publishes a privacy notice for Dessa services effective October 21, 2026 detailing data collection and sharing
- What happened: Block’s privacy notice for the Dessa website, effective October 21, 2026, describes the categories of data collected (identification, device and network attributes, IP address, usage logs), automated tracking technologies such as cookies, and sharing with affiliates and service providers.
- Why it matters: Engineers integrating or evaluating Dessa services must account for the stated data types and third-party sharing in privacy and compliance assessments; the notice specifies retention, cookie use, and categories of third-party recipients.
- Outlook: October 21, 2026 is the effective date for the published privacy notice that governs Dessa’s data practices.
