Why TARX wins on value
Cloud AI products meter remote usage first. TARX starts with free local runtime, then unlocks hosted Supercomputer when your work needs more capacity.

Local usage is always free and unmetered. Paid plans add hosted Supercomputer headroom, reported in Joules with familiar usage indicators for comparison.
Joules + familiar usage indicators
Joules are TARX's native measure of hosted Supercomputer compute. They reflect real usage across reasoning depth, context windows, multimodal work, and runtime duration.
We also show familiar usage indicators so developers can compare hosted TARX usage with the token-based pricing models they already know. We do not publish fake token-to-Joule conversions.
Developers, Teams, Enterprise
Consumer plans package local AI plus Supercomputer headroom. Developer APIs start free locally, unlock hosted Supercomputer with a TARX key, and report hosted usage in Joules plus familiar usage indicators.
Enterprise adds governance, scoped deployment, procurement support, and the option to keep existing model-provider contracts while TARX becomes the runtime, policy, and evidence layer.

Do I need an API key to start?
No. Local runtime is free and does not require an account or key. You only need a TARX key when you want hosted Supercomputer execution.
What are Joules?
Joules are TARX's native unit for hosted Supercomputer compute. They package reasoning depth, context size, multimodal workloads, and runtime duration into one TARX-native meter.
Why show familiar usage indicators too?
Developers already compare AI platforms with token and usage-based models. TARX shows Joules plus familiar usage indicators so teams can forecast without fake conversion ratios.
How does hosted pricing work?
Local execution is always free. Hosted Supercomputer usage is billed in Joules, with clear usage reporting available in your TARX account.
Can enterprise keep existing provider contracts?
Yes. Enterprise can use TARX-managed Supercomputer, customer-scoped deployments, or existing provider agreements with TARX as the runtime, policy, and evidence layer.
