About
ARCgentica is an agentic AI system that solves ARC-AGI-2 challenges by deploying LLM-powered sub-agents to analyze input-output grid examples, write Python transform programs, and evaluate them against test inputs. It achieved 85.28% on the ARC-AGI-2 public evaluation using Claude Opus 4.6, making it one of the top-performing open solutions to this benchmark. It's useful for researchers and developers studying AI reasoning, program synthesis, and abstract pattern recognition.
What it can do
Solve ARC-AGI grid puzzles autonomously
ARC-AGI input-output grid examples → Predicted output grids for test inputs
Synthesize Python transformation programs
Grid pattern examples showing input-output relationships → Executable Python code that transforms input grids to output grids
Analyze abstract visual patterns in grids
ARC-AGI puzzle grid data → Identified transformation rules and pattern descriptions
Evaluate generated programs against test inputs
Python transform programs and test grid inputs → Evaluated solutions with pass/fail scoring results
Run multi-agent reasoning pipelines
ARC-AGI puzzle and selected LLM backend (OpenAI, Anthropic, or OpenRouter) → Coordinated sub-agent analysis and solution attempts
Score and benchmark solution performance
Completed puzzle run results → Accuracy scores and performance metrics across puzzle sets
Generate detailed run logs for AI reasoning research
Executed ARC-AGI solving sessions → Full logs of agent reasoning steps, program attempts, and evaluations
Why it made the leaderboard
If you're researching symbolic AI, program synthesis, or multi-agent LLM architectures, ARCgentica gives you a fully open-source, auditable implementation that achieves one of the highest publicly reported scores on ARC-AGI-2 — a benchmark specifically designed to resist LLM shortcuts. The sub-agent architecture that writes and evaluates Python transformation programs is a concrete, reusable pattern for anyone building reasoning-heavy agent systems.
