Ollama — our take
The de-facto local model runtime: one command to run open models, free and open-source.
- One-command model setup
- Huge model library
- Open-source and free
Chai — our take
Low-friction and cheap to try, but the free message cap makes Premium near-essential.
- Huge bot library
- Very easy to start
- Cheaper annual plan
