A post highlights Jev, a project co-created by a ChatGPT co-creator, which automatically decides when to use Haiku vs a stronger model like Fable — picking the cheapest model that gets the job done (e.g., no need for the top model to count letters), cutting time and cost. It can also pick skills automatically.
