⚡ Power User Tactics — Stretch Free Access Further
Platform Rotation (the sustainable heavy-use strategy)
When claude.ai hits its 5-hour limit — don’t stop. Rotate:
| When | Where |
|---|---|
| claude.ai limit hit | → Duck.ai for quick queries |
| Duck.ai slow | → LM Arena for direct Claude chat |
| Need coding help | → Sourcegraph Cody or GitHub Copilot |
| Need a few premium messages | → Poe compute points |
Each platform’s free tier is independent. Using multiple legitimate free tiers violates no terms of service.
API Cost Tactics (for developers)
| Tactic | Savings |
|---|---|
| Batch API | 50% discount — async processing, non-urgent tasks |
| Prompt caching | Up to 90% reduction — repeated context in API calls |
Promotional Windows (watch for these)
- 14-day Pro trials around major model releases
- Full free month via promo URLs — happened October 2025
- Doubled usage limits December 25–31, 2025 (“holiday gift”)
