DeepSeek

DeepSeek is a family of open-weight models released under an MIT license, known for matching pricier closed models on reasoning and coding.

Effort level

Effort level is a dial for how hard a model thinks before it answers. Turn it up for hard problems, turn it down for speed and lower cost.

Model routing

Model routing sends each task to the cheapest model that can still do it, instead of defaulting to your most expensive model for everything.

Tokens

A token is the chunk of text a model reads and writes in, roughly four characters. Why pricing and context limits are both counted in them.
