Frequently asked questions
Ranked here by quality. Open models now trail the best closed ones by little, and the hosts that serve them often charge much less.
Most "open source" models publish their weights under a license, but not their training data. We list every model whose weights you can download.
On your own hardware, or through inference hosts that charge per token. Open a model's providers to compare each host's price, speed and uptime.
