How JUWEL works.
What JUWEL is, how to start, and what our names mean. Short answers, with links to the full pages.
Start here
JUWEL is the AI supercomputer OS you talk to. Open juwel.ai and start typing. Access and prices are on juwel.ai.
How chats work
01
Start typing
Type what you want to happen. You get a reply in the same thread. You can ask before you sign up.
02
Daily limits
Free and guest use share a daily message limit. When you reach it, JUWEL tells you and shows your options.
Gems
Gems are the AI models we are building for JUWEL. Our goal is a team of focused models that work as one.
Some AI models try to know everything at once. We are trying a different path. One shared base model will learn the basics. Small add-ons will each go deep on one area. JUWEL will pick the right mix for your question.
We plan to release Gems as open weights under the Apache-2.0 license. We will share the finished model files. We will not share how we train them.
Not released yet · We will post the date here when it is set
Fusion Gateway
The Fusion Gateway is how JUWEL will combine AI models. It will send each request to a model that fits the job. Sometimes it will ask more than one and join the answers. It is not live yet.
VKP
VKP is the runtime JUWEL is built on. It runs each step of a task, one after another. Today it is a draft spec. We plan to make it open source.
