Latest work
Introducing Project Kostant
Cogerphere AI Labs releases a research thesis on what it takes to build an Ollama/vLLM for phones — 1–4B mobile-native models, 4-bit kernels, phase-aware NPU/CPU/GPU, compressed KV-cache and speculative decoding.

Introducing Meridian 0.1
Our paper on a LaTeX-aware academic proofreading SLM is published. We introduce Meridian-AC-Nano, a 751.6M-parameter multi-task academic assistant, and make the case that data design and task formulation can deliver large gains without bigger models.
