Managing connections and setting the default
You can manage connections with the various providers and set a default connection yourself. This is useful if you want to talk to Ollama or Anthropic by default, or use a different model on OpenAI.
The connections are managed using the GtLlmConnectionRegistry
class. Individual connections are saved and handled there.

New connections can be added by instantiating a connection with a provider and model and adding it to the registry.
GtLlmConnectionRegistry instance addConnection: (GtLlmConnection new provider: GtOllamaProvider; model: 'llama3.1')
You can also override the default connection to ensure that the next chat or assistant you work with uses that provider by default.
GtLlmConnectionRegistry instance defaultConnection: (GtLlmConnection new provider: GtAnthropicProvider; model: 'claude-3-7-sonnet-20250219')
