Fast mode for V7

Hi everyone,

We're launching V7 model speedups today. This includes the release of the default fast mode, which makes V7 2x cheaper than before (now about the same price as a V6 job).

The model optimizations mean that jobs will take ~40 seconds on fast mode, and 18 seconds on turbo mode.

The new model should have slightly improved hands, but if you want the old version you can still get it via --q 2.

We've also added a new "experimental" --q 4 mode which might give you better coherence and details.

If you find any interesting differences or bugs with any of the versions please let us know in #ideas-and-features

Please Note: --oref jobs are still 2x the cost of a normal --fast mode job and draft mode jobs are unchanged.

Have a nice weekend! ❤️
