What each one is
Gymnasium
Gymnasium is the maintained successor to OpenAI Gym: one API that every RL algorithm and environment speaks.
- The interface the whole RL ecosystem implements
- Dozens of environments included
- Actively maintained, unlike the original Gym
Habitat
Habitat simulates indoor environments at thousands of frames per second so agents can learn navigation and object manipulation from vision.
- Extremely fast photorealistic simulation
- Large library of scanned real homes
- The standard benchmark for embodied navigation
Key differences
Gymnasium is rL environment API, while Habitat is embodied AI simulator. Gymnasium leans more beginner-friendly, whereas Habitat is more suited to intermediate users. In short, Gymnasium fits learning RL, or benchmarking an algorithm against a known baseline, and Habitat fits embodied AI research on navigation and household tasks.
Which should you choose?
Choose Gymnasium for learning RL, or benchmarking an algorithm against a known baseline. Choose Habitat for embodied AI research on navigation and household tasks.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
