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

## AI commentary

> The highlight of this release is the `llm openai endpoint` command, which lets developers quickly test any compatible endpoint without installing the full tool—extremely useful for AI engineers debugging local models or third-party services. The default model upgrade to Luna is also noteworthy for its balanced performance and cost.

## At a glance

Simon Willison released llm 0.32rc2, fixing a dependency issue and introducing two new features: users without a custom default model will now use GPT-5.6 Luna (slightly more expensive but more capable); and a new `llm openai endpoint` command that lets you run prompts, chats, and model listings against any OpenAI-compatible endpoint without prior configuration. The command requires no LLM installation and can be run via a one-liner uvx, greatly simplifying debugging for local or third-party models.

## Key points

- Default model switched from GPT-4o mini to GPT-5.6 Luna, priced at $0.20/M input and $1.20/M output tokens.
- New `llm openai endpoint` command allows direct interaction with any OpenAI-compatible API endpoint.
- The command requires no LLM installation; can be run via `uvx --pre llm openai endpoint`.
- Fixed dependency issues from rc1 for improved stability.

## Full text

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. Tags: llm, uv, lm-studio
