Frequently Asked Questions

OpenCat Quadruped Robot vs Surge AI: which should you choose?

OpenCat and Surge AI serve entirely different markets. Choose OpenCat if you want a hands-on, affordable, open-source robot dog for learning or research; its cost is a one-time kit purchase. Choose Surge AI if you need expert human feedback to train or evaluate frontier AI models, especially for complex reasoning or safety tasks, and have budget for professional services.

Can I use Surge AI to label images for my robot dog project?

Yes, Surge supports custom data labeling for multimodal AI, but it's designed for complex tasks and uses expert labor, so it may be overkill and expensive for simple image labeling.

Does OpenCat include an onboard computer for AI?

No, the base kit uses NyBoard/BiBoard microcontrollers. For AI, you need to add a Raspberry Pi or Jetson Nano (sold separately).

Which tool is better for training a model to follow instructions?

Surge AI is purpose-built for RLHF and instruction following, with benchmarks like ComplexConstraints. OpenCat is for controlling robot hardware, not training LLMs.

Are there any ongoing costs for OpenCat after buying the kit?

No, the kit is a one-time purchase. You may choose to buy add-ons, but the robot works out of the box.

Does Surge AI offer a free trial?

Pricing is contact-based, and there is no mention of a free trial. They likely require a project-based engagement.

Can I use OpenCat with ROS2 for research?

Yes, OpenCat supports ROS and ROS2, making it suitable for robotics research on a budget.

What is the latest benchmark launched by Surge AI?

Surge recently launched Antidote (expert-graded leaderboard), Riemann-bench (moonshot math), GDP.pdf, ComplexConstraints, and Hemingway-bench, all in June/July 2026.

Can I control OpenCat with my smartphone?

Yes, there is a mobile app for iOS/Android that enables remote control and calibration.
