LLM 0.37
New default model
LLM 0.37 adds new models, endpoint setup and a cheaper default
Simon Willison's LLM CLI and Python library reached 0.37, adding the gpt-6.1-sol and gpt-6.1-terra models and an `llm openai endpoint add` command for OpenAI-compatible endpoints. The default model becomes gpt-6-luna at half the previous price, and embeddings now support mixed content-types.
