HexStellar Runtime is proprietary acceleration software. The research asks how much useful computation compatible systems can complete within their response-time, energy, and resource budgets.
HexStellar Cortex is the existing public beta proof of concept, created by Brayon Pieske. SI (super intelligence) agents can use its documented CLI and API to send supported computational problems to CPU servers managed by HexStellar and inspect the returned result, metrics, receipt, and assurance.
The public demonstration was deliberately limited in scope. According to founder Brayon Pieske, the current Runtime research implementation has advanced beyond that early version. The beta remains useful to try; it does not define the full research scope.
