OpenAI cuts off Cursor: your model exit plan on Azure
OpenAI will stop supplying models to Cursor on 12 November 2026, invoking a change-of-control clause after SpaceX's $60 billion acquisition, and Cursor absorbed it because OpenAI carried only 5 percent of its traffic. For Azure buyers the lesson is a model exit plan: what Foundry's lifecycle policy and Microsoft's OpenAI licence actually guarantee, where Claude's EU Data Zone gap bites, the cost of a warm second source, and what DORA already requires.
Anthropic Claude prompt caching pricing: write, read, TTL math
Anthropic prices prompt caching with three numbers: a 1.25x or 2x premium on cache writes depending on TTL, a 0.1x rate on cache reads, and the base input rate for everything after the last breakpoint. This deep-dive verifies every figure against the current official docs and covers per-model minimums, break-even math, batch stacking and how Claude on Azure converts it all into CCUs.
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.
Claude's text watermark: what it means for Article 50
Anthropic will weave an invisible watermark into Claude's text output to meet the EU AI Act's Article 50 marking obligation, applying it globally across the API, apps and cloud platforms including Microsoft Foundry. What the mark can and cannot prove, which deployer duties remain yours, and when a DIY provenance layer still earns its keep on Azure.
Claude on Azure is GA: Foundry deployment and CCU costs
Claude Opus 4.8 and Claude Haiku 4.5 are now generally available in Microsoft Foundry, hosted on Azure with Entra ID authentication, prompt caching, extended thinking and billing through Claude Consumption Units on your existing Azure invoice. Deployment steps, the CCU cost model compared with Azure OpenAI, and the data-residency caveats Swedish and EU teams should assess before production use.
Claude Design: What Anthropic's Figma Challenger Means for Teams
A technical review of Claude Design, Anthropic's April 2026 launch that turns Claude into a visual work tool. Coverage includes the Opus 4.7 multimodal foundation, the design-system learning feature, workflow integration patterns, enterprise considerations, and where Claude Design sits alongside Figma rather than replacing it.
LLM vs AI Agent vs Agentic AI: Drawing the Lines That Matter
The capability spectrum from stateless LLM to multi-agent orchestration is one of the most conflated concepts in the 2026 AI market. The distinctions matter. They change architecture, they change cost by an order of magnitude, and under the EU AI Act they change compliance posture.
Prompt Caching: Cutting LLM Costs Without Quality Loss
A technical guide to prompt caching across Claude, Azure OpenAI, and GPT — what belongs in the cache, how to structure cache breakpoints, TTL realities, hit-rate optimization, and the anti-patterns that erase the savings.
