I released a new version of llm-claude-3 adding support for the new model (and fixing an attachments bug): https://github.com/simonw/llm-claude-3/releases/tag/0.8
llm install --upgrade llm-claude-3
llm keys set claude
# paste API key here
llm -m claude-3.5-haiku 'impress me with your wit'
I also added 3.5 Haiku to my LLM pricing calculator: https://tools.simonwillison.net/llm-prices
Wrote more about Claude 3.5 Haiku on my blog, including this table showing how the price compares to other leading hosted models https://simonwillison.net/2024/Nov/4/haiku/
