  "title": "It’s Tokens All The Way Down: How RLMs are Different — Kevin Madura, AlixPartners",
  "why_included": "RLMs keep large inputs in a programmable environment, letting a model inspect them with code and delegate subsets to submodels instead of attending to every token at once.",
  "summary": "A recursive language model treats context as a variable inside a Python-style REPL, writes code against it, and can delegate selected work to another model. The talk contrasts this with asking a base model to find **12 numbers across 30,000 tokens** directly.",
  "practical_implication": "Consider the pattern for large logs, data frames, repositories, or other inputs that benefit from deterministic slicing and computation. Define typed inputs and outputs, cap iterations, and return only relevant intermediate results to the main model.",
  "agent_context": "A recursive language model treats context as a variable inside a Python-style REPL, writes code against it, and can delegate selected work to another model. The talk contrasts this with asking a base model to find **12 numbers across 30,000 tokens** directly.\n\nConsider the pattern for large logs, data frames, repositories, or other inputs that benefit from deterministic slicing and computation. Define typed inputs and outputs, cap iterations, and return only relevant intermediate results to the main model.\n\nThe cited benchmark rose from **2.6% to 45.4% accuracy**, but the coding-agent comparisons were described as preliminary and potentially unfair. Cost, stopping behavior, sandboxing, and benefits over a carefully built conventional agent still require task-specific tests.",

  "connected_context": {
    "meaning": "This introduces recursive model calls as a selective computation primitive rather than a general multi-agent topology: keep large context outside the main prompt, inspect and slice it deterministically, and delegate only bounded fragments. It strengthens the case for typed interfaces, iteration limits, and compact intermediate results, but the benchmark does not yet show that this outperforms a carefully designed conventional coding-agent harness on comparable tasks.",
