+RubyLLM supports model aliases, so you don't need to remember specific version numbers:
+
+```ruby
+# Instead of this:
+chat = RubyLLM.chat(model: 'claude-3-5-sonnet-20241022')
+
+# You can simply write:
+chat = RubyLLM.chat(model: 'claude-3-5-sonnet')
+```
+
+You can also specify a specific provider to use with a model:
+
+```ruby
+# Use a specific provider (when the same model is available from multiple providers)
+chat = RubyLLM.chat(model: 'claude-3-5-sonnet', provider: 'bedrock')
+
+# Or set the provider after initialization
+chat = RubyLLM.chat(model: 'gpt-4o')
+       .with_provider('azure')
+```
+
+See [Working with Models]({% link guides/models.md %}) for more details on model selection.

-Aliases are particularly useful when you want your code to always use the latest stable version of a model without having to update your codebase when providers release new model versions.
