- Experimental: 4,238 repos (34%)
- Actively developed: 5,609 repos (45%)
Integration Patterns We're Seeing
Analysis of the 609 actively developed Gemini 3 projects reveals three dominant patterns:
1. Firebase + Gemini 3 (38% of active repos)
- Developers already on Firebase trying new Google AI
- Avg 3.4 commits per repo (below average)
- 81% use Cloud Functions for Gemini API calls
- Sentiment: "Worth trying since we're already on Firebase"
2. GCP Migration Projects (29%)
- Teams migrating from OpenAI/Anthropic to GCP ecosystem
- Avg 5.2 commits per repo (highest activity)
- Enterprise projects (private repos with public docs)
- Sentiment: "Cost optimization via GCP credits"
3. Standalone Experimentation (33%)
- Individual developers testing Gemini 3 capabilities
- Avg 1.8 commits per repo (lowest activity)
- Most likely to be abandoned (67% inactive by day 5)
- Sentiment: "Trying it out, but sticking with Claude/GPT"
NPM Download Retention Curve
Week-over-week retention shows developer commitment:
| Day | Gemini 3 Downloads | % Retention | Claude 3 (Week 1) | GPT-4 (Week 1) |
|---|---|---|---|---|
| Day 1 | 142,000 | 100% | 100% | 100% |
| Day 2 | 98,000 | 69% | 87% | 92% |
| Day 3 | 67,000 | 47% | 76% | 84% |
| Day 4 | 54,000 | 38% | 68% | 79% |
| Day 5 | 48,000 | 34% | 64% | 75% |
| Day 6 | 45,000 | 32% | 62% | 74% |
| Day 7 | 43,000 | 30% | 61% | 73% |
Gemini 3's 30% week-one retention is concerning. Healthy AI model launches show 60-75% retention.

Case Studies: Real GitHub Repos Using Gemini 3
Case Study 1: E-commerce Product Description Generator
Developer: Solo indie dev (previous OpenAI user)
Integration: Standalone Gemini 3 API
Activity: 1 commit (abandoned day 2)
Reason for abandonment: "Rate limits made it unusable for batch processing. Went back to GPT-3.5 Turbo."
Case Study 2: Firebase Chat Application
Developer: Small team (3 devs)
Integration: Firebase Cloud Functions + Gemini 3
Activity: 12 commits (actively developed)
Feedback: "Works well within Firebase ecosystem. Pricing is competitive with our GCP credits. Sticking with it."
Case Study 3: Enterprise Code Review Tool
Developer: Mid-size company (50 devs)
Integration: GCP + Gemini 3 (migrating from OpenAI)
Activity: 47 commits (most active repo we tracked)
Feedback: "Cost savings justify the switch. Quality is comparable for code review. Some prompt engineering needed."
Prediction: Will It Stick?
Based on week-one data, we predict:
Likely Scenarios:
- Firebase/GCP users will adopt gradually — Platform integration lowers friction. Expect 30-40% of GCP AI users to try Gemini 3 by Q2 2026.
- Standalone adoption will remain weak — Without distribution advantage, developers prefer Claude/GPT-4. Gemini 3 will capture <15% of non-GCP market.
- Enterprise migration will be cost-driven — GCP credits make Gemini 3 attractive for large teams already on Google Cloud.
Our 30-Day Forecast:
| Metric | Current (Day 7) | Predicted (Day 30) |
|---|---|---|
| Active repositories | 609 | 1,200-1,500 |
| Monthly NPM downloads | 487K | 2.1M-2.8M |
| Stack Overflow questions | 247 | 800-1,100 |
| Market share (vs GPT-4/Claude) | 3.4% | 8-12% |
