The Problem

LLMs cannot verify mathematical proofs reliably.

As shown in Frieder & Hart (2025): "No LLM Solved Yu Tsumura's 554th Problem"

Despite high benchmark scores, all major LLMs fail on rigorous mathematical reasoning:

• ❌ GPT-4o: Correct syntax, wrong logic
• ❌ Claude 3.5: High confidence, low accuracy
• ❌ Gemini 2.0: Plausible but incorrect reasoning
• ❌ LLaMA 3.1: Hallucinated "proofs"

Root Cause: LLMs excel at pattern matching, not rigorous mathematical reasoning.

---

The Solution

ProofCore uses hybrid verification combining rigorous symbolic math with semantic understanding:

Quick Start

Installation

# Clone repository
git clone https://github.com/Flamehaven/Proofcore-AI-Benchmark.git
cd Proofcore-AI-Benchmark

# Install dependencies
npm install

# Run development server (works completely offline)
npm run dev

# Open http://localhost:5173

Offline Mode (Default)

• ProofCore ships with VITE_OFFLINE_MODE=true, so verification works entirely in-browser without starting the FastAPI backend.
• Run npm run setup:pyodide when you need offline Pyodide support; it downloads assets declared in pyodide-manifest.json.
• Run npm run verify:offline-assets to confirm the downloaded files match the manifest before going air-gapped.
• Remote LLM providers stay disabled unless you set ENABLE_LLM_PROVIDERS=true (backend) and provide API keys. Leave them unset for the OSS/offline profile.
• If you do enable networking, also set VITE_ALLOW_NETWORK=true (frontend) so guarded fetches can reach the backend.

Vendoring Pyodide for Offline Use

1. Review pyodide-manifest.json and list the assets you plan to ship (include hashes or SRI strings when possible).
2. Run npm run setup:pyodide to download the files locally under public/pyodide/.
3. Run npm run verify:offline-assets to confirm the downloaded files match the manifest.

Research Benchmark Module (RBM)

• proofcore/research_benchmark/ hosts ProofCore's step-level benchmarking utilities (loader, parser, cascade validator, and metrics).
• Evaluate a dataset via python -m proofcore.research_benchmark.rbm_cli --dataset proofcore/research_benchmark/data_examples/sample_set.json.
• Hooks and metrics mirror the CA proof pipeline and will expand to cover IMO-Bench style evaluations (AnswerBench / ProofBench / GradingBench).
• Python smoke tests under backend/tests_rbm/ keep the RBM stack regression-safe.

Run Tests

# All tests
npm run test

# Performance tests (verify <300ms p95)
npm run test:performance

# Offline guarantee (verify 0 network calls)
npm run test:offline

# Specific performance test
npm run test:perf:symbolic

Build for Production

# Create optimized bundle
npm run build

# Preview production build
npm run preview
