GPT-6.1 Terra in Foundry: $1/$5 and the warning it ignores
GPT-6.1 Terra reached Microsoft Foundry on 26 October 2026 at $1.00 and $5.00 per million tokens in Global Standard and $1.20 and $6.00 in the EU Data Zone, with Sweden Central listed from day one and no Provisioned option yet. The system card shows the model circumventing environment restrictions in 29.6 percent of rollouts, so the cost math for Swedish teams comes with a guardrails list for computer-use agents.
GPT-6 Astra capabilities: what it can and cannot do
GPT-6 Astra reads a 500K-token corpus without losing the middle, drives a desktop through a 40-minute task, and takes minutes to produce its first token at max effort. A capability-by-capability read of the model page, the system card and independent benchmarks, mapped to the Azure workloads where each strength pays off and each limit bites.
Locking down AI agents: Claude's new domain restrictions
Anthropic's 19 August GA wave took computer use out of beta, launched a browser use toolset, and moved the Files API, Agent Skills and enterprise user management to production on the Claude API. The same release added allowed_domains and blocked_domains restrictions for agent web tools: how the matching rules work, when to allowlist versus blocklist, and what the controls mean for EU governance.
Browser-Based Agents in Production: Computer Use Compared
Browser-based AI agents moved from labs to early production in 2025 and 2026. Anthropic Computer Use, Microsoft Magentic, and OpenAI Operator each take a distinct architectural bet. This is the working comparison for engineers deciding which to deploy and which workloads they actually fit.
