What the report covers

The assignment compares AI strategy at Google, Apple, and Microsoft. It is a platform-strategy reading, not a model shoot-out and not a product review of one assistant.

Place each firm in a different default arena, then note overlap.

Three default arenas

Google's public story often ties models to search, advertising, and cloud. Apple's public story often ties features to the device, to the existing hardware line, and to on-device or private processing language. Microsoft's public story often ties models to Azure, GitHub, and workplace software.

These are starting points from official positioning, not exclusive territories. All three now discuss assistants, developers, and enterprise contracts.

What to compare instead of a scoreboard

Useful questions: where does the model run, which product is the distribution channel, and what switching cost is being claimed? A short table with those three rows is stronger than a list of feature names that will be outdated in months.

If the Korean source mentions a preview or a rumor, label it as such. Do not upgrade it to a shipped capability.

Limits

Strategy pages change faster than a course file. Regulation of training data, app stores, and cloud contracts can move a position without a new model name. Date every official source, and

Sources

1. Named official strategy pages or most recent annual reports from Google (Alphabet), Apple, and Microsoft, used only for qualitative statements about cloud, devices, and AI features.
2. Porter, M. E. (1985). Competitive advantage. Free Press, if the source uses a strategy vocabulary of differentiation and scope.
3. A named contemporary review of platform competition, if cited in the source. Do not treat a news rumor as a shipping product.
