<h3 id="delta-mix-qwen-3.5-4b">Delta Mix Qwen 3.5 4B</h3>Dual-encoder routing for Anima 2B / 2.9 / 3.8-0.6B.Keeps the native Qwen 0.6B clip and adds Qwen 3.5 4B only where you ask it to.This is glue, not a new text encoder. The 4B loader and weights stay with the original pack.A separate page for the method is available at <a target="_blank" rel="ugc" href="https://civarchive.com/models/2964040/delta-qwen-35-4b?modelVersionId=3358244">https://civarchive.com/models/2964040/delta-qwen-35-4b?modelVersionId=3358244</a><h3 id="what-it-does">What it does</h3>Two encodes of the same prompt: stock 0.6B on the edges, 4B in the middle.Default mode <code>blocks_ortho</code> projects 4B toward native space, clips per-token spikes <code>delta_guard</code>), then injects a soft block window.Start at strength 0.50 / delta_cap 0.50 / guard on. That is a visible start, not an optimum. The checkpoint moves more than the sliders.<h3 id="works-on-2b-(28)-2.9-(40)-and-3.8-0.6b-(52).-not-the-3.8-q35-connector-pack.">Works on 2B (28), 2.9 (40), and 3.8-0.6B (52).
