ReqLLM.ModelHelpers (ReqLLM v1.4.0)

Helper functions for querying LLMDB.Model capabilities.

Defines helper functions for common capability checks, centralizing knowledge of the model capability structure.

These helpers ensure consistency when checking model capabilities across the codebase and provide a single source of truth for capability access patterns.

true

iex> model = %LLMDB.Model{capabilities: %{}}
iex> ReqLLM.ModelHelpers.reasoning_enabled?(model)
false

streaming_text?(model)

Check if model has streaming.text capability.

Returns true if model.capabilities.streaming.text is true.

Examples

iex> model = %LLMDB.Model{capabilities: %{streaming: %{text: true}}}
iex> ReqLLM.ModelHelpers.streaming_text?(model)
true

iex> model = %LLMDB.Model{capabilities: %{}}
iex> ReqLLM.ModelHelpers.streaming_text?(model)
false

streaming_tool_calls?(model)

true

iex> model = %LLMDB.Model{capabilities: %{}}
iex> ReqLLM.ModelHelpers.streaming_tool_calls?(model)
false

tools_enabled?(model)

Check if model has tools.enabled capability.

Returns true if model.capabilities.tools.enabled is true.

Examples

iex> model = %LLMDB.Model{capabilities: %{tools: %{enabled: true}}}
iex> ReqLLM.ModelHelpers.tools_enabled?(model)
true

iex> model = %LLMDB.Model{capabilities: %{}}
iex> ReqLLM.ModelHelpers.tools_enabled?(model)
false

tools_parallel?(model)
