Claude Opus 4.5 Lands on Microsoft Foundry, and It Is Aiming Straight at Enterprise Workflows
Anthropic’s newest model is not just an assistant. It wants your job backlog
Anthropic has pushed Claude Opus 4.5 into public preview on Microsoft Foundry, giving Azure developers access to one of the most capable reasoning models available.
The release also folds into GitHub Copilot’s paid tiers and Microsoft Copilot Studio, which means Claude is quietly spreading through Microsoft’s entire developer ecosystem.
The pitch behind Opus 4.5 is simple. This version is not just for autocomplete tricks or summarising Slack threads. It is designed to act like a genuine collaborator.
Michele Catasta, president of Replit, summed it up neatly. Having Claude and GPT models in the same environment, he said, gives teams the flexibility to build workflows that move well beyond prototypes and into enterprise-grade automation.
The numbers border on provocative. Claude Opus 4.5 posts an 80.9 percent score on SWE-bench, one of the toughest software engineering benchmarks in use.
Anthropic claims the model can collapse multi-day dev work into a few hours, which effectively turns it into a force multiplier for overstretched engineering teams.
The pricing is aggressive too. It starts at $5 per million tokens for input and $25 per million tokens for output. That places it squarely in the range where real-world teams can justify heavy usage.
Global availability means developers can start using the model now, and a Visual Studio Code integration is on the way via the Foundry extension. Once it arrives, Claude will sit directly inside one of the most widely used code editors on the planet.
The broader significance sits with Microsoft. Foundry is built to give Azure customers menu-style access to the latest AI models, wrapped in enterprise governance and security. Adding Opus 4.5 expands the toolkit and adds pressure on rivals to keep pace.
Claude Opus 4.5 is still in preview, but the direction is obvious. AI models are moving from clever assistants to full project contributors. And Microsoft is making sure Azure is one of the first places that transformation becomes normal.
