FAQ
What is Hexum?
Hexum is the control plane for coding agents. One hexum_live_ key authorizes hosted MCP on hexum.dev and on efficient, arch, review, control, and loop subdomains. hexum_shrink sends this turn instead of the repository. hexum_check fails a forbidden import without calling a model. On MBPP, context dropped about 85% with the same tests passing.
How is Hexum billed?
Hexum bills tokens saved: input minus what still goes to the model. Cache hits are free. No monthly cap. No seat tax. Usage early access from €0.30 per million. Teams from €0.35 per million. See /pricing.
