Chrome Built-in AI Not Available - Region Restriction Query

[RamaswamyGCP]

Description of the bug:

Hello Chrome Team,

I'm developing a Chrome extension using the Built-in AI APIs (Gemini Nano) and encountering availability issues. I'd like to confirm if this is a regional restriction.

=== SYSTEM INFORMATION ===
Browser: Google Chrome Canary
Version: 144.0.0.0
Platform: MacIntel
Location: India
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Safari/537.36
Device Memory: 8 GB

=== AI API STATUS ===
window.ai exists: NO
languageModel API: Not Available
summarizer API: Not Available
writer API: Not Available
rewriter API: Not Available

=== CONFIGURATION ===
✅ chrome://flags/#optimization-guide-on-device-model → Enabled BypassPerfRequirement
✅ chrome://flags/#prompt-api-for-gemini-nano → Enabled
✅ Chrome restarted multiple times
✅ Launched with feature flags via command line

=== ISSUE ===
In chrome://components/, I only see:

• "Optimization Hints (Version: 564)" ✅
• "Optimization Guide On Device Model" ❌ NOT PRESENT

The "Optimization Guide On Device Model" component never appears, preventing Gemini Nano from downloading.

=== WHAT I'VE TRIED ===
✅ Enabled all required flags
✅ Restarted Chrome completely (Cmd+Q)
✅ Launched with --enable-features flags
✅ Clicked "Check for update" on all components
✅ Waited for background download
✅ Verified Chrome version is 144+ (Canary)
❌ Component still doesn't appear

=== QUESTIONS ===

1. Is Chrome Built-in AI currently restricted by region/country?
2. Is India in the supported regions list?
3. Is there a waitlist or gradual rollout based on geography?
4. If regional restrictions exist, what is the timeline for India?

=== REQUEST ===
Could you please confirm:

• Which countries/regions currently have access?
• If India is supported, what additional steps should I take?
• If not supported yet, when can we expect availability?

I have screenshots of chrome://version/, chrome://components/, and chrome://flags/ ready to share if needed.

Actual vs expected behavior:

No response

Any other information you'd like to share?

Thank you for your assistance!
