Fable 5.
If you never tried the new Claude, don't make this mistake:

TL;DR
- Fable-5 is the most intelligent AI model available, capable of complex tasks like interactive chart creation, market research, and co-writing.
- The AI model has different versions: Haiku (fastest, least intelligent), Sonnet (balanced), Opus (very intelligent), and Mythos (formerly smartest, now Fable-5).
- Fable-5 transitions to a pay-per-use model from July 12th, with costs based on input and output tokens, making extended usage expensive.
- Strategic use involves deploying Fable-5 for complex, high-value tasks (1-2 turns) and switching to Opus or Sonnet for routine tasks to optimize costs.
- Advanced prompting techniques are crucial for Fable-5, focusing on setting clear goals rather than simple tasks, with specific prompt structures recommended.
- Connecting Claude to various applications via connectors (Slack, Gmail, Drive, etc.) provides essential context, personalizing AI responses from generic to user-specific.
- The article introduces a skill, '/fable-prompter', to help users generate effective prompts for Fable-5.
- Knowledge management strategies, like creating an 'AI Twin' of key personnel, are discussed to preserve institutional wisdom.
