Which plan to pickFree is enough to find out if the quality suits you. Plus is the one to buy if you make images most days, because the limits stop getting in the way and you get the whole assistant too. Pro is only for people living in ChatGPT all day.Top up $10 to $20 of Playground credits and you will get a couple of hundred standard images. If you already pay for Krea, Magnific or Leonardo, try FLUX there first. Only look at open weights or a self-hosting licence if you have a developer and a reason to run it yourself.Use Free to learn it, but remember everything you make is public. Premium is the plan to buy if you generate often, because relaxed mode means you never hit a hard stop on Leonardo's own image models. Essential is too tight once you touch video or partner models.
