# `PtcRunner.LLM.DefaultRegistry`
[🔗](https://github.com/andreasronge/ptc_runner/blob/main/lib/ptc_runner/llm/default_registry.ex#L1)

Default model registry with built-in aliases for common LLM providers.

Supports multiple providers with unified aliases:
- `"haiku"` -> Uses default provider (configurable)
- `"bedrock:haiku"` -> AWS Bedrock
- `"openrouter:haiku"` -> OpenRouter

## Provider Formats

- `"alias"` - Use default provider with alias (e.g., `"haiku"`)
- `"provider:alias"` - Specific provider with alias (e.g., `"bedrock:haiku"`)
- `"provider:full/path"` - Direct model ID (e.g., `"openrouter:anthropic/claude-haiku-4.5"`)
- `"ollama:model"` - Local Ollama model

## Configuration

    config :ptc_runner, :default_provider, :bedrock

Or via environment variable:

    export LLM_DEFAULT_PROVIDER=bedrock

# `get_model_info`

```elixir
@spec get_model_info(String.t()) :: map() | nil
```

Get detailed info for a model by alias name.

Returns a map with `:alias`, `:description`, and `:providers` keys, or `nil`
if the alias is not found. This is a plain function on `DefaultRegistry` only —
not part of the `Registry` behaviour.

## Examples

    iex> info = PtcRunner.LLM.DefaultRegistry.get_model_info("haiku")
    iex> info.alias
    "haiku"
    iex> info.description
    "Claude Haiku 4.5 - Fast, cost-effective"
    iex> Map.has_key?(info.providers, :openrouter)
    true

    iex> PtcRunner.LLM.DefaultRegistry.get_model_info("nonexistent")
    nil
