Brief

LiquidAI shows that overloading a model context with many tools increases latency and selection errors. They applied LFM2.5-ColBERT-350M to rank 151 tools and keep the top five, reporting fast, reliable filtering even without fine-tuning. A live demo is on Hugging Face and a technical write-up is on their blog.

Why it matters

LiquidAI demonstrates that storing many tools in a model context window raises latency and increases risk of incorrect tool selection.

Key details

  • They used LFM2.5-ColBERT-350M to filter 151 candidate tools down to the 5 most relevant, claiming the filter is fast and reliable without task-specific fine-tuning.
  • Demo available on Hugging Face (huggingface.co/spaces/Liquid…) and further details on their blog (liquid.ai/blog/lfm2-5-retrie…); post dated 2026-06-19 by @liquidai.
Source evidence

Storing too many tools in your context window increases latency and can lead to wrong tool selection.

In this demo, we used LFM2.5-ColBERT-350M as a filter to only select the five most relevant tools among 151 options.

It's fast and reliable, even without any specific fine-tuning.
