Sydney

Sydney fixed my type "marry" automatically.

langwhat 'marry ball washington' -s

langwhat 'marry ball washington' -s -z

Caching

Responses are much faster when cache hits, and token usage becomes 0.

Note that Sydney doesn't support counting token usage, and always shows 0.

lw teddy --show-token-usage

lw teddy --show-token-usage

Features

• Uses few-shot prompting to reduce model mis-behavior
• English by default for superior response speed and accuracy
• Supports supplying API Key via either environment variable or config file at ~/.config/langwhat/api_key.txt
• Supports using Sydney with -s flag
• Caching responses in a local sqlite database
