What happened
OpenAI evaluated its GPT‑6 Astra model on the Furniture Assembly (FAB), a 60‑image test suite of IKEA builds that includes intentional assembly mistakes. Astra identified mistakes in 80% of the cases, beating the next‑best models—Anthropic’s Claude Fable 5.1 (70%) and Claude Opus 5 (61%). The test gave each model the assembly manual, a zoom tool, and a Python interpreter, with an 80‑step budget per image. Astra completed the tasks in a median of three minutes, far faster than competitors, though still too slow for real‑time feedback.
The researchers at Epoch AI created the Furniture Assembly (FAB) to evaluate visual‑spatial reasoning in AI. FAB consists of 60 photographs from three IKEA furniture builds, each paired with the official assembly manual and a set of tools for image inspection.
During evaluation, each model received the manual PDF, a zoom capability, and a Python interpreter, and could take up to 80 reasoning steps per image. If the model reached the step limit, it received a warning and a final answer prompt.
GPT‑6 Astra, OpenAI’s latest vision‑enabled model, correctly identified mistakes in 48 of the 60 images, yielding an 80% score. The next‑best performer, Anthropic’s Claude Fable 5.1, scored 70%, while Claude Opus 5 achieved 61%. Other evaluated models from Google, Moonshot, and Alibaba lagged further behind.
Astra’s median processing time was three minutes per image, substantially faster than competitors, though still above the sub‑second latency required for interactive assistance.
Why it matters
The result shows that frontier language models can now combine visual perception with textual instructions to spot physical errors, a capability that underpins future real‑time assistance for complex assembly, repair, and maintenance tasks. By demonstrating a clear leap in both accuracy and efficiency, GPT‑6 Astra narrows the gap between AI reasoning and practical, on‑site problem solving. However, the three‑minute response time indicates that further speed improvements are needed before the technology can be deployed as an interactive guide for consumers or technicians. The also reveals differing failure modes across model families, informing future research on robustness and error detection.
The ability to link visual inputs with textual instructions and pinpoint errors demonstrates a level of embodied reasoning that could be applied to automotive repair, appliance troubleshooting, and other hands‑on domains.
Higher accuracy and lower token usage suggest that newer models are becoming more efficient, reducing computational costs for developers who might integrate such capabilities into consumer products.
The highlights that model size or complexity alone does not predict performance; factors like mistake subtlety and viewing angle play significant roles, indicating areas for targeted improvement.
The three‑minute latency, while a record for current vision‑language models, remains a barrier for real‑time user interaction, underscoring the need for hardware acceleration or algorithmic optimizations.
