The three big enterprise AI assistants — ChatGPT Enterprise, Microsoft 365 Copilot, Gemini Enterprise — look similar but differ sharply on the things Indian enterprises care about: data residency, lock-in and pricing. Here’s the grounded comparison. (dgm implements osFoundry, a separate company’s platform — dgm is an independent integration partner, not osFoundry.)
At a glance
| ChatGPT Enterprise | M365 Copilot | Gemini Enterprise | |
|---|---|---|---|
| Ecosystem | OpenAI | Microsoft 365 | Google Cloud/Workspace |
| India residency | Data at rest in India | In-country delayed to end-2026 | India region allowlisted, reduced |
| Pricing | Not public | ~₹1,495.73/user/mo (+GST) | Adaptive subscription |
| Models | OpenAI only | OpenAI-family | Gemini only |
| Lock-in | High | High (needs M365) | High (Google stack) |
(Facts per OpenAI Asia residency, Microsoft India Copilot pricing + in-country processing blog, Google Gemini locations. Confirm current details with each vendor.)
They mostly track your existing stack
The pragmatic reality: the “best” of the three is usually whichever ecosystem you already run.
- Microsoft shop → Copilot is most native (but requires an M365 licence, and India in-country processing is delayed to around end-2026).
- Google shop → Gemini Enterprise integrates with Workspace (but its India region is allowlisted and runs a reduced model set — no Gemini 2.5 Pro).
- Neither / OpenAI-first → ChatGPT Enterprise, which has the clearest India answer: data residency at rest in India.
The India residency scorecard
For DPDP-sensitive enterprises, residency is the differentiator: ChatGPT Enterprise stores data at rest in India today; Gemini offers an allowlisted, reduced India region; Copilot’s in-country processing is delayed. Confirm each vendor’s current status — these move quarter to quarter.
The shared limitation: single-vendor lock-in
All three are single-vendor assistants tied to their own models and ecosystems. The alternative is a model-neutral platform: osFoundry lets you use any provider’s models via your keys (including all three vendors’ models), route per request, build agents and apps, and self-host in India — usage-priced with no per-seat fee. See the individual breakdowns: vs ChatGPT Enterprise, vs Copilot, vs Gemini. osFoundry is younger with limited independent coverage, so dgm validates fit.
How dgm helps
dgm helps Indian enterprises compare these three against a neutral platform on cost, residency and lock-in, and implements osFoundry where provider choice and self-hosting matter. Transparent pricing: $399 assessment, $3,999/month implementation, no per-seat fees (INR approximate; 18% GST for domestic clients). Explore the platform at osFoundry, or talk to dgm to choose.
