Almost everyone starts by paying four separate twenty-euro subscriptions and only notices months later. The right choice depends entirely on whether you are chatting, creating, building on top of a model, or running things at volume — and the switching point between them is a number you can work out in ten minutes.

Pick by what you are actually doing
You pay for three or four AI subscriptions already
GlobalGPT. One bill across several leading models is worth it the moment you are paying two of them separately and using neither fully.
Try GlobalGPTYour spend is spread across writing, images, video and voice
Lorka. A bundle only wins if it replaces at least two things you already pay for — add up today’s bills before you switch, not after.
Try LorkaYou are building on a model rather than using a chat window
Z.ai. Credits and an API are the right shape for something that runs without you sitting in front of it.
Try Z.ai (GLM)You generate image or video at real volume
WaveSpeedAI. Work out your cost per run against your current plan — that single comparison is the whole reason to move.
