RLM Router for large content processing

Implementations§

Source§

impl RlmRouter

Source

pub fn should_route( output: &str, ctx: &RoutingContext, config: &RlmConfig, ) -> RoutingResult

Check if a tool output should be routed through RLM

Source

pub fn smart_truncate( output: &str, tool_id: &str, tool_args: &Value, max_tokens: usize, ) -> (String, bool, usize)

Smart truncate large output with RLM hint

Source

pub async fn auto_process( output: &str, ctx: AutoProcessContext<'_>, config: &RlmConfig, ) -> Result<RlmResult>

Automatically process large output through RLM

Based on “Recursive Language Models” (Zhang et al. 2025):

  • Context is loaded as a variable in a REPL-like environment
  • LLM writes code/queries to analyze, decompose, and recursively sub-call itself

When FunctionGemma is enabled, the router sends RLM tool definitions alongside the analysis prompt and dispatches structured tool calls returned by the model (or reformatted by FunctionGemma).
