Meanings in context

Editorial equation guide

The one-time computation used to learn from the initial training data.

Article-grounded definition

pretraining compute.

\rho \;=\; \frac{C_{\mathrm{RL}}}{C_{\mathrm{pre}}}

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

C_{\mathrm{pre}} \approx 6ND,

This equation gives an approximation: it relates the quantities while allowing an approximation.

C_{\mathrm{total}} = C_{\mathrm{pre}} + C_{\mathrm{post}} + Q \cdot \bar{c}_{\mathrm{inf}},

The total compute bill has three parts: pretraining, post-training, and all the requests served afterwards.

C_{\mathrm{pre}}

pretraining compute.

C_{\mathrm{pre}} \approx 6 N D,

This equation gives an approximation: it relates the quantities while allowing an approximation.
