Image model
Prism 0.5
Nexa's first-generation image model for visual creation, concept art, image ideation, and creative workflows.
Roadmap
Ember 1.0
The next planned Ember release focused on stronger reasoning, lower latency, and better browser assistance.
Roadmap
Prism Next
Planned visual model improvements for sharper prompt following, higher fidelity, and richer creative control.
Built around private inference
Nexa is designed as private company infrastructure first: local/private model APIs, CUDA-aware runtime work, streaming responses, and permission-aware product surfaces.
Streaming assistant
Ember 0.5 streams responses token by token so Nexa feels active while the model is generating instead of waiting for a completed answer.
Image workspace
Prism 0.5 is connected to Nexa Images, where users can create, search, reopen, inspect, and manage generated visuals from their account.
Browser direction
Nexa is being built toward page understanding, form assistance, research support, and user-approved browser actions with safety controls.
Simple, transparent pricing
Plans map to real product access: higher chat usage, richer assistant features, memory, images, and team controls.
