## Summary

Google’s Gemini 4 Carbon has reached the top spot on the Artificial Analysis Intelligence Index v5, scoring 59 points. This performance is driven by strong results in complex reasoning, knowledge, and scientific tasks, specifically leading in four of the nine index evaluations. The model is currently in a limited rollout to selected users and is not yet available to the general public. Google is offering a 50% launch discount with no confirmed end date.

In coding agent tasks, Gemini 4 Carbon ranks second only to Claude Opus 5.5. It scores 59 on the Artificial Analysis Coding Agent Index, just three points behind Claude Opus 5.5’s score of 62. This marks a significant improvement for Google, which has historically lagged in this specific area. The model also shows gains in agentic knowledge work, improving its Elo score by 126 points over the previous Gemini 4 Argon, though it remains behind models like Grok 4.7 and Kimi K3.1 Pro.

At standard pricing of $4 per million input tokens and $20 per million output tokens, Gemini 4 Carbon costs approximately $7.76 per Intelligence Index task. This is about 23% less than Claude Opus 5.5 and slightly higher than GPT-6 Astra. The model supports a 1M token context window and accepts text, image, video, and speech inputs, though it only outputs text. Its hallucination rate is 11%, which is lower than competitors like Claude Opus 5.5 and GPT-6 Astra, both at 50%.

## Key points

- Gemini 4 Carbon scores 59 on Intelligence Index v5, leading in four of nine evaluations.
- It ranks second in coding agents, scoring 59 versus Claude Opus 5.5’s 62.
- Standard pricing is $4/$20 per 1M tokens, with a current 50% launch discount.

## Why it matters

Gemini 4 Carbon’s top ranking signals Google’s return to the frontier in reasoning and coding. Its lower cost per task compared to Claude Opus 5.5 offers developers a competitive alternative for high-performance agentic workloads.
