🚨 Disaster Response Coordination OpenEnv

Teaching an LLM to Triage Disasters — An RL Environment Where the Stakes Are Real

---

"Most RL environments train agents to play games. We trained one to save lives."

---

🎯 Hackathon Theme: Theme #3.1 - Professional Tasks

This environment targets Theme #3.1 (Professional Tasks: Emergency Operations). It moves beyond "chatting" and requires the agent to perform real, hard work: maintaining a persistent world model of 15 simultaneous disasters, managing a finite resource budget, and orchestrating a multi-step triage workflow where shortcuts lead to immediate failure.

🌪️ The Problem Nobody Is Solving

During a natural disaster, Emergency Operations Centers (EOCs) are overwhelmed by thousands of frantic incident reports simultaneously. A flooded neighborhood, a chemical plant fire, a hospital wing collapse — all arriving at once. Human coordinators have seconds to decide:

• Is the toxic gas leak more urgent than the trapped school bus?
• Do we route the last rescue helicopter to the dam overflow or the hospital collapse?
• Which reports are duplicates? Which are life-threatening?

Human coordinators burn out. Triage errors cost lives.

Existing AI benchmarks test code generation and math — not the fog-of-war, resource-constrained, multi-agent hell that is real disaster response.

We built the environment that does.

🏗️ How the Environment Works

Disaster Response Coordination OpenEnv is a multi-step RL environment built on OpenEnv where an AI agent acts as an Emergency Incident Commander.

The agent receives a live incident ticket queue — real-world disaster reports — and must triage them under time pressure with a fixed resource budget.

What the Agent Sees (Observation Space)

Every step, the agent receives:

• 📋 Full inbox snapshot with per-ticket completion status
• 💰 Current resource budget remaining
• 🕐 Action history (last 8 actions)
• ❌ last_action_error for self-correction feedback
• 💡 Valid action hints for curriculum learning

What the Agent Does (Action Space)

For every incident ticket, the agent must complete an exact 4-step workflow:

classify → set_priority → draft_reply → submit_ticket

Field	Type	Valid Values
action_type	enum	classify, set_priority, draft_reply, submit_ticket, next_ticket, finish_episode
predicted_team	enum	rescue, medical, utilities, shelter, logistics, general
predicted_priority	enum	low, medium, high, urgent
reply_text	string	Max 2000 chars. Graded for actionability.

Reward Function

ticket_score = 0.40 × team_routing + 0.30 × priority_score + 0.30 × reply_quality

task_score  = avg(ticket_scores)
            - invalid_penalty     (max 0.15)
            - loop_penalty        (max 0.10)
            - reroute_penalty     (max 0.12)
            - budget_penalty      (max 0.18)
            - time_pressure       (Hard mode only, 0.75× multiplier)

We use dense, partial rewards at every step. No sparse end-of-episode signals. This is critical for RL training stability — if you get the team right but the priority wrong, you still learn something.

Difficulty Tiers — Based on Real Disasters

Tier	Budget	Scenarios	Real-World Basis
🟢 Easy	40 units	Single-team, clear incidents	Napa Valley gas leaks, Houston flash floods
🟡 Medium	48 units	Multi-agency, ambiguous routing	2012 North India Grid Failure (7 states)
🔴 Hard	55 units	Cascading mass-casualty + time pressure	2020 Vizag Gas Leak, 2018 Kerala Floods, 2023 Turkey earthquake

💡 Built for the "Winning Tip"

The hackathon organizers suggested: "Focus on the quality of your envs and reward signals... iterate on training runs... you have a way higher chance of winning."

We built this environment specifically to satisfy these winning principles:

1. Dense, High-Quality Reward Signals: We don't use binary pass/fail logic. We reward agents for every correct sub-task (+0.40 for team, +0.30 for priority). This allows smaller, 7B/8B models (like Llama-3-8B or Qwen2-7B) to learn efficiently from partial success.
2. Optimized for Rapid Iteration: The environment is a lightweight FastAPI server that responds in milliseconds. You can run hundreds of training episodes per hour, perfect for iterating on training runs instead of waiting for a "huge" model to finish.
3. Compute-Budget Friendly: Because we use strictly typed Pydantic models and stateless logic, the environment is easy to pair with QLoRA training or other memory-efficient techniques.

⚖️ Why This Environment Cannot Be Reward-Hacked

Most RL environments get gamed within 100 steps. We built explicit defenses:

1. 5 independent reward signals — passing one doesn't mean passing all
2. Anti-gaming penalties:
   • Re-routing after submission: -0.02 per reroute
   • Infinite loop detection: -0.015 per redundant action
   • Budget overflow: -0.06 per violation
   • Late-resolution time pressure (Hard only): 0.75× multiplier
3. Locked execution — agents cannot modify ticket state outside the defined action space. No globals, no hidden state.

"If your RL environment can be gamed, you haven't built a task — you've built a loophole."

🧠 Training with GRPO (Unsloth + TRL)

We trained Qwen2.5-7B-Instruct using GRPO (Group Relative Policy Optimization) via Hugging Face TRL + Unsloth on a Google Colab T4 GPU.

Training Setup

Parameter	Value
Base model	unsloth/Qwen2.5-7B-Instruct-bnb-4bit
Algorithm	GRPOTrainer (HF TRL)
LoRA rank	r=16
Quantization	4-bit (bitsandbytes)
Epochs	3 stages, 135 total steps
Reward source	Live HF Space API (real environment feedback)
Hardware	Google Colab T4 GPU

The reward function connected directly to our live HF Space. Every training step sent real incident prompts to the environment and received real rewards back — no static dataset, no simulation shortcut.

What We Discovered: Sparse Reward Collapse

Before training, the model hallucinated invalid outputs:

team: "emergency_services"   ❌  (not in the valid set)
team: "utility repair"       ❌
priority: "very-high"        ❌  (not in the valid set)
priority: "immediately"      ❌

After training, the model learned strict valid action spaces:

team: "rescue"               ✅
priority: "urgent"           ✅

We observed sparse reward collapse — a known RL failure mode where a small model (7B at 4-bit) struggles to optimize across a multi-step workflow with interdependent rewards. This validates our environment's quality: it is genuinely difficult enough to expose real RL failure modes that larger models or longer training would overcome.

📈 Benchmark Results

Agent	Easy	Medium	Hard	Avg Score	Status
Deterministic Heuristic Baseline	0.704	0.683	0.660	0.682	✅ All Pass
GRPO Qwen2.5-7B v2 (Ours)	0.641	0.665	0.601	0.636	✅ All Pass

Why the RL model scores close to a hardcoded baseline — and why that's impressive: The heuristic baseline uses hand-crafted regex patterns with zero generalisation. Our trained model dynamically reads the incident context and generates unique, contextually accurate handoff notes for every scenario. It passes all 3 difficulty tiers without any hardcoded rules — purely from learned behavior.

🖥️ Live Tactical Command Dashboard

▶️ Open the Command Center →

We built a military-style tactical dashboard that updates in real-time via WebSocket as the agent processes tickets.

• 🗺️ OpenStreetMap — live incident markers with radar pulse animations (red = urgent, orange = high, ✓ = submitted)
• ⚡ ARIA — AI Incident Analyst powered by Gemini, analyzes any incident on demand
• 📊 Live metrics — score tracker, resource budget, threat level bar, team routing
• 🔔 Operations feed — every agent action broadcast live with audio alerts

Dashboard URL	Purpose
/ui/?task=all	Full command center — all 15 incidents
/ui/?task=easy	Easy tier only
/ui/?task=hard	Hard tier — cascading scenarios
/web/	OpenEnv default interface

🚀 Quickstart

1. Run the Environment Locally

git clone https://github.com/letsjoyn/meta-scalar-hack.git
cd meta-scalar-hack
pip install -e .

# Start the OpenEnv server
python -m uvicorn server.app:app --host 0.0.0.0 --port 8000

# Open the dashboard
# → http://localhost:8000/ui/

2. Run the Agent ✅ (Recommended for Judges)

Uses the free HF Router with Qwen 72B — no dedicated endpoint needed, works for anyone with an HF token:

$env:OPENENV_BASE_URL = "https://joynnayvedya-disaster-response-openenv.hf.space"
$env:API_BASE_URL     = "https://router.huggingface.co/v1"
$env:MODEL_NAME       = "Qwen/Qwen2.5-72B-Instruct"
$env:HF_TOKEN         = "hf_YOUR_TOKEN"

py inference.py

To run against a local server (faster): set $env:OPENENV_BASE_URL = "http://localhost:8000" and run the server from Step 1 first.

3. Run with the Fine-Tuned V2 Model (Our Training Evaluation)

We evaluated our disaster-response-v2 LoRA adapter using a dedicated HF Inference Endpoint (TGI). To replicate: deploy joynnayvedya/disaster-response-v2 to a HF Inference Endpoint, then:

$env:OPENENV_BASE_URL = "https://joynnayvedya-disaster-response-openenv.hf.space"
$env:API_BASE_URL     = "https://YOUR_ENDPOINT.endpoints.huggingface.cloud/v1"
$env:MODEL_NAME       = "tgi"
$env:HF_TOKEN         = "hf_YOUR_TOKEN"

py inference.py

4. Validate OpenEnv Compliance

openenv validate
