xAI founder and Tesla ($TSLA) CEO Elon Musk publicly praised Alphabet’s ($GOOGL) newly unveiled Gemini 4 Carbon frontier model as "impressive" on October 28 after the AI system claimed the top spot across major industry benchmarks and delivered breakthrough performance in automated cybersecurity defense and vulnerability patching.
Key performance benchmarks, cybersecurity achievements, and pricing details for Gemini 4 Carbon include:
- Ranking on Frontier Benchmarks: Released just two weeks after Gemini 4 Argon, Gemini 4 Carbon ranked overall on the updated v5.0 Artificial Analysis Intelligence Index with a score of 59, outperforming rival frontier models including Anthropic’s Claude Opus 5.5 and OpenAI’s GPT-6 Astra across coding, multi-step agentic workflows, and reasoning tasks.
- Breakthrough Cybersecurity and Zero-Injection Record: In cybersecurity evaluations, Gemini 4 Carbon performed over 10x better than publicly available models when generating high-quality security patches and hunting software vulnerabilities. On Gray Swan’s Indirect Prompt Injection (IPI) benchmark, Carbon achieved a 0.0% attack success rate—resisting every evaluated attack attempt (down from Argon’s 0.7% rate)—while cutting unsupported claims in half and reducing high-severity misalignment alerts by nearly 80% in live internal coding tests.
- Competitive API Pricing and Token Efficiency: Google introduced Gemini 4 Carbon with a promotional rate of $2 per million input tokens and $10 per million output tokens through the end of 2026 (with standard pricing set at $4 per 1M input and $20 per 1M output tokens, and cached inputs discounted by 95%), making it roughly 23% cheaper per completed task on the Intelligence Index than Claude Opus 5.5.
