Clarity pass over the main text (36-item audit), Discussion rewrite and cut, acknowledgements, Souly et al. as ref 62, lettered SI panels, model section moved under Results; plus the untracked curriculum/society/compose/smol configs, runners, figures, stats and tests that the SI already cites.

# llm_merge_seeds_smol — the Fisher–Muller replication on a second base lineage (SmolLM2-1.7B-Instruct)
|
||
|
||
**Claim tested (manuscript revision 2026-09-12).** Every language-model result in the paper used one
|
||
model lineage (Qwen2.5). Does "merged specialists exceed every parent" hold on an unrelated base?
|
||
Base: `HuggingFaceTB/SmolLM2-1.7B-Instruct` (Apache-2.0, Llama architecture, different lab and
|
||
pretraining corpus). Identical protocol to `llm_merge_seeds` (three disjoint families, 600 training
|
||
tasks, 3 epochs, rank-16 LoRA, fixed 100-task test sets, soup and TIES merges, 5 training seeds);
|
||
`adapters_dir: models/llm_smol` keeps the specialist cache apart from Qwen's. Ran on one L40S in
|
||
12 min (`hpc/llm_smol.pbs`). Numbers from `figures/stats_llm_smol.py`; figure `llm_smol.png` (both
|
||
lineages side by side).
|
||
|
||
### Result — replicates, 5/5 seeds, with the same magnitudes
|
||
| contrast (SmolLM2) | overall | worst family |
|
||
|---|---|---|
|
||
| soup − best specialist | +0.049 ± 0.022 (5/5 seeds) | +0.190 ± 0.045 (5/5) |
|
||
| TIES − best specialist | +0.097 ± 0.020 (5/5) | +0.202 ± 0.077 (5/5) |
|
||
| *(Qwen2.5-0.5B, for reference)* soup − best | +0.040 ± 0.035 (4/5) | +0.200 ± 0.020 (5/5) |
|
||
| *(Qwen)* TIES − best | +0.055 ± 0.020 (5/5) | +0.204 ± 0.016 (5/5) |
|
||
|
||
Absolute levels: best specialist 0.610 ± 0.013 overall / 0.128 worst-family; soup 0.659 / 0.318;
|
||
TIES 0.707 / 0.330. Falsifier (not triggered): merged ≤ best specialist in a majority of seeds.
