OpenEnv Hackathon SF — Self-Improvement (Statement 4) + Snorkel AI
An RL environment where LLM agents learn to negotiate salary packages against 5 simulated hiring experts with hidden priorities that shift over time.
Live App : https://huggingface.co/spaces/yashj2110/negotiation-arena-v2 Model : https://huggingface.co/yashj2110/salary-negotiation-qwen-1.5b
Metrics: Training Metrics Result
Total Reward = 0.2 × Format + 0.5 × Negotiation + 0.3 × Deal Quality
| Component | Weight | What it measures | Score |
|---|---|---|---|
| Format | 20% | Valid action type (propose, counter, accept, reject, walk_away) | 1.0 valid, 0.0 invalid |
| Negotiation | 50% | Outcome quality — deal terms vs baseline ($140k, 2.5%, 90 days) | +1.0 above baseline, +0.5 at baseline, -1.0 no deal, +0.2 early close bonus, -0.1 per turn |
| Deal Quality | 30% | Snorkel-weighted utility across 4 labeling profiles | +0.3 if utility ≥ 0.5, else 0.0 |
Each profile is a different "judge" evaluating the same deal with different priorities:
| Profile | Salary Weight | Equity Weight | Start Date Weight | Prioritizes |
|---|---|---|---|---|
| Balanced | 0.4 | 0.3 | 0.3 | Equal mix |
| Cash-heavy | 0.7 | 0.1 | 0.2 | Maximize salary |
| Equity-heavy | 0.2 | 0.6 | 0.2 | Maximize equity |
| Fast-start | 0.2 | 0.2 | 0.6 | Start ASAP |
Example: Deal closes at $150k salary, 3% equity, start in 30 days.
| Step | Salary | Equity | Start Date |
|---|---|---|---|
| Raw value | $150,000 | 3.0% | 30 days |
| Normalized (0–1) | 150k/200k = 0.75 | 3%/5% = 0.60 | 1 − 30/180 = 0.83 |
Balanced profile score: 0.4×0.75 + 0.3×0.60 + 0.3×0.83 = 0.73 → ≥ 0.5 → reward = +0.3
The profile rotates with the expert, so the agent can't optimize for just one definition of "good deal."
Screenshots:
- 5 Expert Personas with distinct personalities, deal-breakers, and hidden priorities
- Information Asymmetry — agent must infer expert priorities from conversational cues
- CurriculumManager — agent's weaknesses drive next epoch's training data
- SelfPlayChallenger — epoch N model becomes epoch N+1 opponent
- Snorkel Drift — preferences shift every 8 episodes
