A Reddit post claims a model codenamed "Gemini 4 Hyperion" has appeared inside Google Antigravity (both CLI and App). Note: all claims trace to scattered X leaks and are unverified by Google.
According to the post:
- Hyperion is the successor to Carbon, designed to maximize raw knowledge using fast iterative algorithms that feed its own output back for self-checking dozens of times; an internal employee reportedly calls it "indistinguishable from a human"
- Rumored benchmarks: 99.7% SWE-Bench Pro, 84% HLE, 100% RiemannBench, 96.3% Val's Finance Index, 91.2% ExploitGym, 84 AA Index
- Cost and pricing unknown
