## Gemini 4 Argon's Absence
Gemini 4 Argon hasn't appeared on Epoch AI's benchmark index because Google keeps it behind limited access.
## Top Models on Index
Claude Opus 5.5 leads at 167.35, followed by GPT-6 Astra at 166.51, Claude Sonnet 5.5 at 165.2, and Claude Fable 5.1 at 164.82.
## Google's Model Access
Google launched Gemini 4 Argon on September 30 but restricted it to vetted cybersecurity defenders through its Fairwind Program.
## Index Methodology
The Epoch Capabilities Index uses item response theory to stitch scores from fifty benchmarks into one scale anchored by Claude 3.5 Sonnet at 130 and GPT-5 at 150.
## Google Funded the Index
Google DeepMind's AGI Safety and Alignment team helped fund the ECI's methodology paper called 'A Rosetta Stone for AI Benchmarks'.
## Confidence Intervals
The gap between top models sits within four-point confidence intervals, meaning a two-point edge isn't a demonstrated ordering.
## Convergence of Models
Anthropic and OpenAI have converged so tightly that the ECI can't cleanly separate them, while Google's model isn't even in the running.
## Google's Rollout Strategy
Google rolled out Gemini 4 Argon through Fairwind Program for cybersecurity partners, with a token limit of one million per response.
## Key takeaway

Gemini 4 Argon, Google's latest AI model, ties for third on Epoch AI's benchmark but is restricted to cybersecurity partners due to limited access.
