JayB_Official · reddit · 2026-07-30
A developer has released CORTEX // MODEL OBSERVATORY, an open-source tool (Apache 2.0) designed to streamline mechanistic interpretability into a visible workflow. It helps everyday users and researchers observe the inner workings of local LLMs.
- Architecture Support: Originally built around GPT-2 and Llama, it currently supports tier 1 generation observation for most local LLMs.
- Target Audience: The UI is easy for beginners to read while offering depth for experts.
- Background: The creator heavily leveraged AI to build the tool, effectively replacing the need for a full research department. The project is available on GitHub for community testing and contributions.
