Claude (model family)
A family of large language models developed by Anthropic, heavily utilized for coding, agentic orchestration, and complex analysis due to their deep reasoning capabilities.
What it is
The Claude model family consists of tiered AI models that balance speed, cost, and intelligence. The Claude model family from lowest to highest capability: - **Haiku** — fastest, cheapest, good for simple/routine tasks - **Sonnet** — balanced capability and cost, best for most day-to-day work - **Opus** — high capability, suitable for complex multi-step tasks - **Fable** — frontier-class, generally available, best for the most demanding reasoning tasks; costs approximately 2x Opus - **Mythos** — frontier-class with safety restrictions lifted in specific domains; restricted access (cybersecurity partners, Project Glasswing); same underlying model as Fable with domain-specific safeguards removed
When you would use it
You select a Claude model as the backend for complex autonomous agents or IDE integrations that require high reliability and deep architectural understanding.
Common operations
- Driving agentic coding tools like Claude Code and Windsurf.
- Analyzing entire codebases dropped into a single massive context window.
