Claude Sonnet 5.5
Claude Sonnet 5.5 is Anthropic’s mid-tier Claude 5.5 model designed for fast, well-scoped everyday work, coding, and professional document creation. Anthropic says it runs more than 30% faster than Claude Sonnet 5 and typically costs up to 30% less per task while keeping the same base token pricing. The model shows major gains in agentic coding, with a 70.6% score on Terminal-Bench 4.0 and stronger performance on FrontierCode and CursorBench than its predecessor. Sonnet 5.5 also performs strongly on knowledge work, computer use, chart understanding, and long-horizon tasks, in some cases approaching Claude Opus 5.5 at higher effort settings. Anthropic positions it as especially useful for debugging, routine coding, collaboration, and producing polished documents, slides, spreadsheets, and user interfaces. Claude Sonnet 5.5 is available across Anthropic’s platforms as well as AWS, Google Cloud, and Microsoft Azure.

Gemini 4 Argon
Gemini 4 Argon is Google's frontier AI model designed for complex, long-horizon workflows across software engineering, enterprise knowledge work, cybersecurity defense, and creative writing. The model supports coding, reasoning, multimodal understanding, and multi-step agentic tasks, with an expanded output limit of up to 1 million tokens for particularly long or complex trajectories. Google reports that Argon scores 77.9% on DeepSWE v1.1 for long-horizon software engineering and 51.3% on AutomationBench for end-to-end business automation. Its enterprise capabilities extend to areas such as financial research, legal research and drafting, professional chart analysis, long-video understanding, and workflows involving multiple documents. Argon is also designed for defensive cybersecurity and can autonomously identify, validate, and patch software vulnerabilities, tying for first with a 68% score on CWE-bench v1 in Google's reported results.

Claude Mythos 5.1
Claude Mythos 5.1 is Anthropic’s newest Mythos-class model, designed for advanced cybersecurity, biology, scientific research, coding, and long-running knowledge work. It is the same underlying model as Claude Fable 5.1 but uses different safeguards: Fable 5.1 is generally available, while Mythos 5.1 is restricted to trusted access programs with safeguards specifically designed for cybersecurity and life sciences research. The model sets a new performance frontier for agentic coding and demonstrates the strongest cyber capabilities of any Anthropic model released to date. In scientific research, Mythos 5.1 can work with specialized tools and complex workflows across molecular design, computational biology, and other technical domains. In Anthropic’s experiments, it designed high-affinity protein binders across multiple targets and achieved its strongest measured hit rate to date. It also optimized seven open-source protein and genomics deep learning models.
