// ABOUT EX5 LABS

Making compute a market,
not a subscription.

EX5 is built by infrastructure engineers — schedulers, billing systems, market plumbing. ex5.ai applies that discipline to AI: an open GPU market with transparent spot prices, open-weight models, and one balance across every layer. If a market can price electricity fairly, it can price an H100.

sample data
OPEN BY DEFAULT

EX-1's weights, our serving stack and the CLI are public. Anything we ask you to trust, you can read.

SUPPLY SIDE WINS

Hosts and agent builders keep 80%. Marketplaces die when the supply side is squeezed — ours compounds.

PRICE IS PUBLIC

Spot charts, the EX5CI index and per-token prices are open — no "contact sales" wall in front of a number.
