Pewter developer docs

Pewter, by Omega Compute, is a marketplace for GPU capacity. Sellers list whole GPUs or supported GPU slices and connect the machine with a small agent. Buyers find capacity, agree terms, and run jobs. Everything is reachable three ways: a REST API, an MCP server for assistants and agents, and command-line tools.

Status

Pewter is in active development and the code is private. Pages marked coming soon or not yet available describe parts that are not built or not decided yet.
