Arc Agi 2 Solver

# 🏆 ARC-AGI-2 Solver — 4× L4 GPU Production Pipeline **Competition:** [ARC Prize 2026 (ARC-AGI-2)](https://www.kaggle.com/competitions/arc-prize-2026-arc-agi-2) ## 🚀 Quick Start (Kaggle 4× L4 GPUs) ### Step 1: Add Model as Kaggle Dataset Go to [julien31/Soar-qwen-14b](https://huggingface.co/julien31/Soar-qwen-14b) and add it as a Kaggle dataset (or use the Kaggle Models integration). Mount it at `/kaggle/input/soar-qwen-14b`. **Alternative (smaller):** Use [julien31/Soar-qwen-7b](https://huggingface.co/julien31/Soar-qwen-7b) — set `USE_14B = False` in the script. ### Step 2: Install SGLang (in notebook first cell) ```python !pip install "sglang[all]>=0.4.7" aiohttp requests --quiet ``` ### Step 3: Run the Solver ```python !python kaggle_notebook.py ``` That's it! The script handles everything: - Launches 2× SGLang servers (14B model, TP=2 each) across 4 GPUs - Solves tasks in parallel using SOAR program synthesis - Falls back to heuristics for easy tasks - Outputs `submission.json` in Kaggle format --- ## 🎯 Architecture ### GPU Utilization: 2× Soar-qwen-14b (TP=2) ``` GPU 0 + GPU 1 → SGLang Server A (14B model, tensor parallel) GPU 2 + GPU 3 → SGLang Server B (14B model, tensor parallel) ``` - **14B scores 42.75% vs 7B's 36.25%** on ARC-AGI-1 (SOAR paper Table 1) - 2 servers = parallel task solving, no PCIe bottleneck - Each server handles 120 tasks independently ### Solving Pipeline (per task) ``` 1. Heuristic check (instant) → 12+ pattern matchers ↓ (if no match) 2. SOAR Program Synthesis: a. Sample 60 programs from Soar-qwen-14b b. Execute each → check against training examples c. Refine top programs with execution feedback d. Weighted majority vote → top-2 answers 3. Submit pass@2 predictions ``` ### Key Innovation: Verified Solutions Programs that produce correct outputs for ALL training examples are **provably correct** for the test input (assuming the task has a unique transformation). This gives us high-confidence predictions that other approaches (direct grid prediction) cannot guarantee. --- ## 📊 Expected Performance | Component | ARC-AGI-2 | ARC-AGI-1 | |-----------|-----------|-----------| | Heuristics only | 2.1% | 5.0% | | SOAR-7B (30 samples) | ~5-10% | ~15-25% | | SOAR-14B (60 samples + refinement) | ~10-20% | ~30-42% | | SOAR-14B + full 6K budget | ~20-30% | ~42%+ | | 2025 competition winner (NVARC) | 24% | — | **Key factors for higher scores:** - More samples per task (budget 3000-6000 vs our 60) - Multiple SOAR self-improvement iterations - Ensemble with TTT transduction model - Larger model (32B or 72B) --- ## 📁 Files | File | Purpose | |------|---------| | **`kaggle_notebook.py`** | **🎯 Main submission script** — run this on Kaggle | | `run_soar_eval.py` | Standalone SOAR evaluation (for benchmarking) | | `arc_data.py` | D8 augmentations, color permutations, TTT data | | `program_synthesis.py` | SOAR evolutionary search engine | | `ttt_engine.py` | Test-Time Training with LoRA + PoE scoring | | `enhanced_heuristics.py` | 20+ pattern-matching heuristics | | `arc_solver.py` | Multi-track ensemble solver | | `kaggle_submission.py` | Alternative single-file submission | --- ## 🔧 Configuration Options Edit the top of `kaggle_notebook.py`: ```python USE_14B = True # True = 2×14B (TP=2), False = 4×7B (TP=1) PROGRAMS_PER_TASK = 60 # More = better accuracy, slower REFINEMENTS_PER_TASK = 30 TEMPERATURE_SAMPLE = 0.9 # Higher = more diverse programs TEMPERATURE_REFINE = 0.7 # Lower = more focused fixes ``` **Time budget estimation:** - 240 tasks × 60 samples × ~2s/sample = ~8 hours with 2 parallel servers - Plus refinement + heuristics: ~10 hours total (within 12h limit) --- ## 📚 Literature Foundation This solver is built on the exact methods from the top ARC Prize 2025 winners: | Paper | Key Contribution | Score | |-------|-----------------|-------| | [SOAR (2507.14172)](https://arxiv.org/abs/2507.14172) | Evolutionary program synthesis + self-improvement | 52% ARC-1 | | [Product of Experts (2505.07859)](https://arxiv.org/abs/2505.07859) | DFS + multi-augmentation scoring | 71.6% ARC-1 | | [TTT (2411.07279)](https://arxiv.org/abs/2411.07279) | Per-task LoRA + augmented inference | 61.9% ARC-1 | | [ARC-AGI-2 (2505.11831)](https://arxiv.org/abs/2505.11831) | Benchmark definition | — | | [ARC Prize 2025 Report (2601.10904)](https://arxiv.org/abs/2601.10904) | Competition winner analysis | 24% ARC-2 | ### SOAR Model Performance (from paper Table 1) | Model | 1-shot | Sample-6k | Sample&Refine-6k | SOAR-6k | |-------|--------|-----------|------------------|---------| | **Soar-7B** | 1.0% | 5.6% | 14.25% | **36.25%** | | **Soar-14B** | 1.0% | 12.6% | 19.87% | **42.75%** | | Soar-32B | 1.5% | 12.9% | 25.25% | 44.37% | --- ## 🔑 Key Insights 1. **ARC-AGI-2 is dramatically harder than ARC-1** — o3 drops from 53% to 3% 2. **Program synthesis > direct prediction** — verifiable solutions are the key advantage 3. **Refinement is critical** — SOAR Sample&Refine outperforms pure sampling by 2-3× 4. **14B > 7B** — 42.75% vs 36.25% with same compute budget 5. **L4 PCIe limits TP** — independent copies (TP=1 or TP=2) beat TP=4 due to no NVLink ## Models & Datasets - **Primary model**: [julien31/Soar-qwen-14b](https://huggingface.co/julien31/Soar-qwen-14b) (14.7B params) - **Fallback model**: [julien31/Soar-qwen-7b](https://huggingface.co/julien31/Soar-qwen-7b) (7.6B params) - **Training data**: [julien31/soar_arc_train_5M](https://huggingface.co/datasets/julien31/soar_arc_train_5M) - **Benchmark**: [arc-agi-community/arc-agi-2](https://huggingface.co/datasets/arc-agi-community/arc-agi-2)
