Oct 28 (Reuters) – Alphabet’s Google on Wednesday unveiled Gemini 4 Carbon, its latest frontier AI model, ​stepping up competition with OpenAI ‌and Anthropic as the race to build more capable coding and cybersecurity systems intensifies.

The launch comes two weeks after ‌Google ​introduced Gemini 4 ⁠Argon, as the ⁠company expands its Gemini family of AI models for developers and enterprise customers.

Here are some details:

• ​The company said the Carbon model delivers state-of-the-art performance across ⁠cybersecurity tasks including ⁠vulnerability discovery, exploitation, and software ​patching

• Google said Carbon generates secure ​code at more than twice the ‌success rate of Gemini 4 Argon on internal benchmarks

• The model is designed to handle complex, ⁠long-running engineering and coding tasks

• Carbon is being made available first to a ⁠subset ‌of cybersecurity defenders through ⁠Google’s Fairwind Program as the ​company ‌continues testing safeguards

• Gemini ​4 Carbon ⁠will be priced at $2 per million input tokens and $10 per million output tokens, matching Gemini 4 Argon’s introductory pricing
