Microsoft ships security that runs two competitors' models alongside its own
Project Perception finds and fixes flaws by routing each task to the right model. Cheap for triage, expensive only for hard reasoning.
Microsoft put three competitors inside one product
Project Perception runs models from Microsoft, OpenAI and Anthropic at once, picking the cheapest one that can handle each task. The same week, Google delayed its flagship model and Anthropic locked in 2 gigawatts with AMD.

Google delays its flagship model and the stock drops over 4%
Internal testing showed it falling short on coding and long-horizon reasoning. A fast version shipped in its place.
From the studio
Model routing became a shelf product
The story of the week isn't a new model. It's Microsoft announcing a security platform that uses models from three different companies, two of them direct competitors, with a layer deciding which one answers each request: cheap model for triage, expensive model only when the reasoning demands it.
Anyone running a system with AI recognises the design, because it's the same arithmetic you do on a cost spreadsheet. The difference is that it left the improvisation of individual teams and became an advertised feature of a large product, which means the practice stopped being a trick for the frugal and became reference architecture.
What that choice admits in public is the interesting part. It concedes that no single vendor offers the best cost-to-result ratio across every task, and that tying a product to one model is a commercial convenience rather than an engineering decision.
The week's other stories reinforce it by contrast. Google delayed the broad release of its flagship after unsatisfying internal tests and the stock fell. Anthropic locked in capacity with AMD and bought equity in the supplier. Each solving, in its own way, the same problem: how not to depend on a part you don't control.

A supplier underwriting its buyer concentrates risk in one balance sheet
Guarantees at this scale tie a manufacturer's results to a single customer's commercial success.

A coding tool reaches 5 million users a week
The number shows the assistant left the experiment and entered the routine. It changes what code review has to cover.
Hardware
The memory price increase now shows up in the largest budgets
Twenty-five billion of Microsoft's capex increase is price alone. The squeeze runs through the whole chain.
Security
Continuous code scanning only became viable when the cost fell
The core argument of Microsoft's product isn't finding more flaws. It's finding them sooner, because it can now run without pause.
Business
Three different strategies for one problem: not depending on the manufacturer
Buy equity, design your own chip, etch the model into silicon. The week put all three answers side by side.
