**TL;DR** - UBTech $18M annual compensation package for AI research scientist signals ongoing war for AI talent at top end.
1. Benchmark ML engineer compensation against Levels.fyi and Glassdoor - market moved fast
2. If you cannot compete on cash, compete on interesting problems, compute budget, and publishing freedom
3. Retention equity and milestone-based bonuses more effective than base salary for keeping researchers
**Example Prompt:**
Design a compensation structure for a senior ML researcher balancing cash, equity, and compute budget.
| Pros | Cons |
|---|---|
| $18M signals where the ceiling is | Most companies cannot compete at this level |
| Interesting problems beat cash for some researchers | Research freedom often comes with IP strings attached |
|---|---|
| Compute budgets are genuine differentiator | Researchers want publications, conflicting with secrecy |
