Why it mattersIf you let AI agents handle customer refunds in the UK, the CMA says you carry the legal blame for their breaches.
Watch nextWatch whether the CMA turns this guidance into action against a named company.
Seventy's viewBefore agents touch refunds, name an owner for their conduct and train them like new staff.
What happened. The UK Competition and Markets Authority has published guidance on using AI agents with customers, for tasks like handling refunds. It says a business is responsible if its agent breaks consumer law, and it urges proper training of agents.
Why it mattersAn openly licensed AI this small can now operate a computer, so test it before paying for a bigger one.
What happened. Microsoft released Mage-VL-Cowork, a 4B-parameter AI that operates a computer by clicking on screenshots and by running code in a terminal. It scores 66.0% on OSWorld-Verified with a 50-step budget, the best result among 4B models.
Why it mattersUS government suppliers on can now run OpenAI's GPT-5.6 models at higher volume, with traffic spread across both Regions automatically.
What happened. Amazon Bedrock in AWS GovCloud (US) now supports OpenAI's GPT-5.6 models, Terra and Luna, across the Responses, Converse and Chat Completions APIs. Cross-Region Inference also now routes requests between both GovCloud (US) Regions for higher throughput.
Why it mattersUS government security teams and contractors on can now use an AI built for exploit testing, but only after identity verification.
What happened. OpenAI's Daybreak Red, a version of GPT-5.6 tuned for security research, can now be used by approved customers through Amazon Bedrock in the AWS GovCloud (US-East) region. It is meant for vetted defenders doing vulnerability research, exploit reproduction and fix development, with fewer refusals and tighter identity checks and monitoring.
Why it mattersOnce AI assistants carry out multi-step tasks, one request can trigger many model calls, so per-team spend tracking must be set up first.
What happened. AWS published a playbook for finance and platform teams on tracking and controlling Amazon Bedrock spending. It argues that comparing per-model prices and shortening prompts is not enough once usage grows, because leaders need to know which team spent what, on which workload, and whether it was within budget.
Why it mattersIf you build or sell AI agents in the UK, four regulators now expect you to show how existing applies to them.
What happened. The CMA has published research on how consumers use AI agents today and where that is heading, plus guidance for businesses on meeting their legal duties. On 30 October 2026 the CMA, FCA, ICO and Ofcom, which together make up the DRCF, also issued a shared position on AI agents acting for people.
Why it mattersIf your product or staff use ChatGPT, expect stricter intervention in some conversations, and a public OpenAI safety report to cite in risk reviews.
What happened. OpenAI is adding safeguards in ChatGPT aimed at preventing violence, stepping in earlier when conversations raise concern. It has also committed to publishing public safety reports.
Why it mattersUS government contractors with -only security rules can now let developers use OpenAI's Codex without sending data outside that boundary.
What happened. The ChatGPT desktop app, including its Work task tool and the Codex coding assistant, can now be used through Amazon Bedrock in AWS GovCloud (US). A walkthrough shows how to set up Codex so its AI traffic stays inside GovCloud identities, endpoints and regional controls.
Why it mattersMicrosoft tests Copilot on simulated companies rather than customer data, so your own sensitive files are not part of its evaluation.
What happened. Microsoft built a platform that generates full-scale fake company environments to test Copilot, using public information like job ads, government occupation records and SEC filings. The simulated workplaces copy real business workflows so Microsoft can spot problems without touching customer data.
