+* Token Management Strategy Research
+
+** Initial Findings
+
+*** OpenRouter Free Tier
+- URL: https://openrouter.ai/collections/free-models
+- Providers moving from free to paid-only models
+- Belief: "Free models play crucial role in democratizing access"
+
+*** Google AI Studio (Gemini)
+- Free tier available
+- Limits: 60 requests/minute, 300K tokens/day
+- No credit card required
+- Every API key gets these limits
+
+** Research Questions
+
+1. Which providers offer free or low-cost tiers?
+2. What are the rate limits and quotas?
+3. Which models are best for which use cases?
+4. How to optimize context windows?
+5. What is the cost per token breakdown?
+
+** To Research Further
+
+| Provider | Free Tier | Paid Tier | Best For |
+|----------|-----------|-----------|----------|
+| Google Gemini | 300K tokens/day | Pay per use? | General, coding |
+| OpenRouter | Varies by model | Per-request | Routing, variety |
+| OpenAI | ? | ? | GPT-4 quality |
+| Anthropic | ? | ? | Claude capabilities |
+| Mistral | ? | ? | Open weights |
+| Local | Hardware cost | Free | Privacy, control |
+
+** Token Optimization Strategies to Explore
+
+1. *Tiered Model Usage*
+   - Simple tasks: Fast/cheap models
+   - Complex tasks: Stronger models
+   - Fallback: Lower tier if higher fails
+
+2. *Context Compression*
+   - Summarize long contexts
+   - Use RAG instead of full context
+   - Prune old conversation
+
+3. *Caching*
+   - Cache common responses
+   - Reuse embeddings
+   - Batch requests
+
+4. *Hybrid Approach*
+   - Local models for simple queries
+   - Cloud APIs for complex tasks
+   - Manual review for critical outputs
+
+** X Account Access
+
+*Pending:* X account access via Google login
+*Blocker:* Requires OTP from user per security rule (SOUL.md)
+*Action needed:* User provides OTP, I complete OAuth, access bookmarks
