LLM 0.32rc2 Released: Default Model Upgraded to GPT-5.6 Luna, New OpenAI-Compatible Endpoint Command

Release: llm 0.32rc2

Hot on the heels of RC1, this fixes a dependency issue and also adds two neat new features:

• The default model for users who have not set their own default is now GPT-5.6 Luna. It was previously GPT-4o mini. Luna is a much better and more recent model, albeit slightly more expensive - $0.20 per million input tokens and $1.20 per million output tokens, compared to $0.15/$0.60 for 4o mini. You can switch back to 4o mini using llm models default gpt-4o-mini, or switch to GPT-5 nano, an even cheaper default model ($0.05/$0.40), using llm models default gpt-5-nano. #1576
• New llm openai endpoint command for running prompts, chats and model listings against arbitrary OpenAI-compatible endpoints without first configuring a model. These calls are not logged. #1565

The llm openai endpoint command is really cool. I got frustrated at the lack of an obvious CLI tool for trying out prompts against arbitrary OpenAI Chat Completions imitation endpoints, so I decided to add that to LLM itself.

You don't even have to install LLM to use this. Here's a uvx one-liner for running a prompt - with tools - against an LM Studio local model:

uvx --pre llm openai endpoint http://127.0.0.1:1234/v1 \
  T llm_version -T llm_time --td \
  -m google/gemma-4-31b 'what is the current LLM version? And the time?'

Output here.
