Claude 5.5: What you need to know about Anthropic's AI models and chatbot

Summary

Claude is Anthropic's family of LLMs (Fable, Opus, Sonnet, Haiku) and a chatbot, offering tiered models for various tasks from fast, affordable processing to complex research and agentic coding. It features tools like Artifacts for interactive content, multi-agent Research, and persistent Projects and Skills for repeatable workflows.

  • Claude offers four main models (Fable, Opus, Sonnet, Haiku) with varying capabilities, speeds, and costs.
  • Artifacts allow creating interactive apps, data visualizations, and shareable tools directly within the chatbot.
  • The Research feature uses a multi-agent approach to generate comprehensive reports from many sources.
  • Projects provide persistent workspaces with saved context for recurring tasks, while Skills define repeatable processes.

Engineers and product teams looking to leverage advanced AI for complex tasks, coding, research, and workflow automation will find value in Claude's specialized features and tiered models.
