Guide Labs vs Reka (2026)
Updated March 10, 2026
Overview
Guide Labs is building the first inherently interpretable LLMs. Their open-source Steerling-8B model features a novel concept layer inserted into the transformer architecture that makes every generated token traceable back to its training data. Unlike post-hoc explainability tools, Guide Labs bakes interpretability directly into the model, achieving 90% of standard model capability with less training data. YC-backed with $9M seed.
Reka builds multimodal AI models capable of processing text, images, video, and audio.
