OpenAI's GPT-6 Astra Can Spot IKEA Assembly Mistakes With 80% Accuracy
Key Takeaways
- Epoch AI's Furniture Assembly Benchmark (FAB) photographs three IKEA pieces during assembly with deliberate errors, and models must compare the photos against instructions, identify the mistakes and describe what went wrong.
- In November 2025 the best model, Claude Opus 4.5, scored only 28 percent on the benchmark.
- Ten months later, OpenAI's GPT-6 Astra reaches 80 percent accuracy, taking roughly three minutes per photo.
- Claude Fable 5.1 follows at 70 percent and Claude Opus 5 at 61 percent.
