ProviderConfig

Identifies a specific LLM provider, model, and connection details.

Each subtype carries the credentials, endpoint URL, and context-window metadata needed to construct an org.llm4s.llmconnect.LLMClient via org.llm4s.llmconnect.LLMConnect. Instances are normally obtained from org.llm4s.config.Llm4sConfig.defaultProvider or org.llm4s.config.Llm4sConfig.provider, which resolve configured named providers under llm4s.providers.

Prefer each subtype's fromValues factory over its primary constructor: fromValues resolves contextWindow and reserveCompletion automatically from the model name, so you only need to supply credentials and endpoint.

This trait is deliberately '''not''' sealed. In Scala 3 sealed confines subtypes to the same source file, which would keep every provider's config in this one file forever and make a provider supplied by another module impossible. Implementations are therefore expected from outside llm4s-core, and consumers must not assume the set of subtypes is closed: describe a config through providerId, endpointUrl and withModel rather than by pattern-matching on its runtime type.
