Ahead on:
- Reliability, 85 against 60

Ahead on:

- Maintenance & community, 85 against 80

Watch for: No public price, trial or self-serve signup. Access starts with a demo request

## Verdicts

**Gemini Enterprise.** The assistant is callable through a GA v1 method with a 99.5 per cent SLA, OAuth through IAM, a public Discovery document and optional Model Armor screening. Seat prices weren't found on Google's pages, onboarding needs a billing account and a person, and some Gemini agent capabilities announced on 8 October are early access.

**Glean.** Three public OpenAPI specs (Client, Indexing, Platform) regenerated almost daily, plus llms.txt and Markdown docs. No public price, trial or self-serve signup. Access starts with a demo request.

## Before you call either

### Gemini Enterprise

1. Create a Gemini Enterprise app first. StreamAssist needs its APP_ID, and the caller needs `discoveryengine.assistants.assist`
2. Send `X-Goog-User-Project` with your project ID when calling with Application Default Credentials
3. Pass the `session` name from the final stream message on the next call to keep context. Leaving it empty starts a new session
4. Read `connectorAuthErrors` in the response. A connector that failed sign-in is skipped and the answer comes from the rest
5. Use the A2A URL returned by Agent Registry verbatim. It takes the project number, not the project ID

### Glean

1. Get the backend host from the Glean admin. APIs answer at https://<instance>-be.glean.com and MCP at that host under /mcp/<server-name>
2. Ask for a user-scoped token with only the scopes the task needs. A global token can impersonate whoever `X-Glean-ActAs` names
3. Keep chat under 0.5 calls a second and search under 5, and back off on 429
4. Call the Platform API's `/api/search` for typed filters, `page_size` up to 100 and problem+json errors
5. Send `X-Glean-Exclude-Deprecated-After` in tests to catch fields due for removal
