Qwen3-0.6B · F5 Terminal Balanced

F5 freezes the Unsloth UD-IQ2_M base. For each of 196 projections, a rank-eight correction is reconstructed from packed INT4 codes by a shared 18→64→64→8 decoder with layer-specific FiLM gains and biases. We trained the codes and all 13,064 decoder/FiLM parameters together, giving terminal turns extra weight (1.75; first-token factor 2.5) and using a language KL term (0.05). The base plus compact correction occupied 271.35 MB in the original experiment. The exported adapter is 10.12 MB; it must be loaded alongside the 268.70 MB base at scale 1.

In-house evaluation

Counts are passes out of all tasks. Fresh, A6 and A8 score complete trajectories; A6 and A8 are known task sets. The language perplexity uses the same 2,040 scored tokens from Alice in Wonderland on CPU; lower is better.

Check Result
Fresh tool-use trajectories 5/48
Known A6 trajectories 12/48
Known A8 trajectories 9/48
Next action from supplied history 8/24
Full continuation from supplied history 0/24
Strict English 20/96
Alice perplexity ↓ 38.7522
