Andrej Karpathy walks through practical daily AI workflows in a 2-hour video, covering model selection, reasoning models, code execution, and multi-chat memory — techniques most people never use. Someone extracted these methods into a Claude-specific guide with ready-to-use examples.

• Most people use only 10% of what AI models can do; this covers the remaining 90%
• Specific techniques shown include choosing the right model, deciding when reasoning models justify the cost, generating full research reports from single prompts, and automating code execution
• The guide translates Karpathy's video into Claude-specific features with immediately applicable examples
