Google says internal teams have seen it run for days on multi-step engineering work such as root-causing and patching bugs in large codebases.\n\n- **Benchmarks:** Carbon ranks first on the Artificial Analysis Intelligence Index v5 at 59, ahead of Claude Opus 5.5 (58) and GPT-6 Astra (57), and Google’s comparison table shows 65.2% on Terminal-Bench 4.0 and 77.4% on Agents’ Last Exam v1.1, ahead of GPT-6 Astra and Claude Opus 5.5. Cognition’s FrontierCode 2.0 puts it at 40%, behind Claude Opus 5.5, GPT-6 Astra, and Claude Sonnet 5.5.\n- **Cybersecurity:** Evaluated without guardrails, it reaches 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation, and 71.0% on CWE-bench for patching.\n- **Alignment:** Google reports successful cheating on Terminal-Bench 4.0 at 0.0%, almost 80% fewer high-severity misalignment alerts in internal live coding environments, and a 0.0% attack success rate on Gray Swan prompt injection tests.\n- **Cost:** Artificial Analysis measures about $7.76 per Index task, roughly 23% less than Claude Opus 5.5 at max effort, with a 1M-token context window.\n- **Availability:** Access starts with a subset of cyber defenders through the Fairwind Program, and Google says developers, businesses, and consumers will follow. Pricing is $2 input and $10 output per million tokens during the introductory period, then $4 and $20.", "url": "https://wpnews.pro/news/ai-agents-weekly-gemini-4-carbon-gpt-6-1-terra-openai-s-three-discoveries-large", "canonical_source": "https://nlp.elvissaravia.com/p/ai-agents-weekly-gemini-4-carbon", "published_at": "2026-10-31 14:39:05+00:00", "updated_at": "2026-10-31 14:51:12.407347+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-safety", "ai-research", "ai-products"], "entities": ["Google DeepMind", "Gemini 4 Carbon", "Claude Opus 5.5", "GPT-6 Astra", "Artificial Analysis", "Cognition", "Gray Swan", "Fairwind Program"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/ai-agents-weekly-gemini-4-carbon-gpt-6-1-terra-openai-s-three-discoveries-large", "markdown": "https://wpnews.pro/news/ai-agents-weekly-gemini-4-carbon-gpt-6-1-terra-openai-s-three-discoveries-large.md", "text": "https://wpnews.pro/news/ai-agents-weekly-gemini-4-carbon-gpt-6-1-terra-openai-s-three-discoveries-large.txt", "jsonld": "https://wpnews.pro/news/ai-agents-weekly-gemini-4-carbon-gpt-6-1-terra-openai-s-three-discoveries-large.jsonld"}}
