AI BriefingAnthropic Unveils Embody Benchmark
Key point
Anthropic analyzed the correlation between models and interfaces through the Embody benchmark, which measures LLMs' ability to control physical robots.
Details
Anthropic has released the Embody benchmark to measure how well language models can control robots in the physical world. This research systematically analyzes not only the model's intelligence but also the impact of the robot's Body and control Interface on performance.
The research team defined four levels of control interfaces for their experiments:
- Direct Control: Directly instructing low-level actions such as joint torque
- Programmatic Control: Writing Python code to control the robot
- Policy Control: Delivering high-level commands to a pre-trained policy
- RL Supervision: Training a policy by designing reward functions, etc.
The experimental results showed that model performance varies significantly not just based on model size, but also on which interface is used to connect to the robot. In particular, Claude Mythos Preview showed the highest performance, and it was confirmed that physical capability improves with each successive model generation. Additionally, the findings suggest that resolving the gap between the model's inference speed and the robot's real-time control cycle is a key challenge for real-world robot deployment.
