LLM Function Calls Don't Scale: Code Orchestration Is Simpler, More Effective

2025-05-21
LLM Function Calls Don't Scale: Code Orchestration Is Simpler, More Effective

Feeding the full output of tool calls back into LLMs is costly and slow. This article argues that output schemas, enabling structured data retrieval, allow LLMs to orchestrate processing via generated code – a simpler and more effective approach. Traditional methods, where tool outputs are fed back to the LLM as messages for next-step determination, work well with small datasets but fail with real-world scale (e.g., large JSON blobs from Linear and Intercom MCP servers). The article proposes code execution as a fundamental data processing method, using variables as memory, and code to orchestrate multiple function calls for scalable data processing, overcoming the cost, speed, and potential data loss issues of LLMs handling large datasets. This necessitates secure, stateless AI runtime environments, currently in early development.

Immunotherapy Timing: A Game Changer?

A study suggests that administering immunotherapy infusions before 3 PM significantly improves cancer patient outcomes compared to later infusions. Patients receiving treatment earlier experienced longer disease control (11.3 months vs. 5.7 months) and median survival (at least 23.2 months vs. 16.4 months). This seemingly risk-free and cost-free improvement has sparked debate. While some skepticism remains, multiple retrospective studies and a randomized clinical trial support the finding, suggesting optimal immunotherapy timing may be earlier in the day, potentially linked to the body's circadian rhythm. Further research is needed to understand the mechanism, but this could lead to updated immunotherapy guidelines.

Axolotl Regeneration: Cracking the Code for Limb Regeneration

Scientists have identified retinoic acid as a key molecule in the limb regeneration of axolotls, amphibians known for their remarkable regenerative abilities. This molecule forms a gradient across the body, guiding regenerating cells to rebuild the correct tissues in the right places. Experiments showed that increasing retinoic acid levels caused axolotls to regenerate entire limbs, rather than just the missing part. This research offers a promising avenue for human limb regeneration, suggesting that we might one day be able to regenerate injured tissues and organs like axolotls.

The Enigmatic Octobass: A Giant Among Instruments

The octobass, a rare and unusual instrument, is known for its immense size and incredibly low register. Invented in 1850 by Jean-Baptiste Vuillaume, this giant instrument requires a complex system of pedals and levers to play. Its deep sound is so low that some notes fall below the range of human hearing; the vibrations can only be felt. Today, only a handful of octobasses exist, mostly in museums. The Montreal Symphony Orchestra uniquely owns one and occasionally incorporates it into their performances.

Advent of Code: Elegant Solution to a Stateful Parsing Problem

2025-04-09

The latest Advent of Code puzzle involves interpreting `do()` and `don't()` instructions that enable or disable the contribution of `mul` instructions to a sum. Regular expressions struggle with this statefulness, as they recognize stateless regular languages. The author uses a parser-based solution, lifting it into a state transformer to create a stateful parser. This parser efficiently handles `do()`, `don't()`, and `mul` instructions, processing roughly 1MB of input in 0.12 seconds—a significant improvement over a regex-based approach.
