Three dials on every model
Use the lesson to respond to this. "A teammate says the Fast variant costs more because it is a smarter model. What is actually different?" Keep the answer plain.
Step 1 of 2
Three dials on every model
Past the name, a model has three dials. Read each as a fit for the task.
How much code the model can hold at once.
Pick the largest window when the task spans a lot of code.
Low up to high. Grok 4.7Cursor and SpaceXAI's current lead Cursor model, in the weekly pool at $2 per million input tokens and $6 per million output, with a 256k context window and a 500k variant; above 256k input tokens it bills at 2x the standard rate.

Crank it up for hard debugging; drop it for a quick wired-table lookup.
The fast variant costs more.
As one speaker describes it, it runs the same model on different GPUs. You pay for the hardware.
A checkout returns a 500 for one customer's cart and nobody knows why.
Pick: a smarter, longer-running model, reasoning effortA model dial (high / medium / low) for how hard the model thinks before responding, set separately from which model and how fast it runs. Press Enter for the full definition. high, standard speed. Lean on Fast only if minutes matter.
