Reproducing J-space and Reading Model's Hidden Thoughts
vikvang1 · x · 2026-07-11
The author reproduced Anthropic's J-space research and migrated it to Llama-3.3-70B, claiming they can "read" the model's thoughts hidden in J-space.
Key takeaways:
- They split concept vectors (like secrecy, elephant, democracy) into J-space and "subconscious" components, injecting them separately.
- The model directly reports thoughts from J-space but is "blind" to non-J-space content.
- Even if the model verbally denies it, the author notes the NLA can still capture hidden thoughts, which continue to influence its behavior.
- The post includes a code link, emphasizing this is a reproduction and extension of Anthropic's "Global Workspace in Language Models" research.
