Tiered models separate public and private capabilities
Article summary
Quick briefing — cleaned from the original RSS feed
Open‑weight checkpoints now hand over every model capability to anyone who can download the file. A tiered architecture splits the network into public and private branches, and a secret key flips a small permutation of parameters to route computation through the private sub‑graph. Because the key governs the internal graph rather than the input, the extra abilities remain invisible to users who lack it. This moves capability control from a post‑hoc filter to the model’s core design.…
