The Super Intelligence Compute Index (SICI) is an onchain benchmark of hourly rental prices for five NVIDIA GPUs: H100, B200, H200, A100, and RTX 4090. The index combines those prices at fixed weights, with the H100 weighted most heavily, and uses marketplace data compiled by LO:TECH. On Injective, SICI is available through a perpetual market with USDC as margin and up to 10x leverage. The index is intended to provide exposure to GPU rental-price movements and a market through which compute users may hedge price risk.
