### Overview:
Lamarck-14B is a carefully designed merge which emphasizes [arcee-ai/Virtuoso-Small](https://huggingface.co/arcee-ai/Virtuoso-Small) in early and finishing layers, and midway features strong influence on reasoning and prose from [CultriX/SeQwence-14B-EvolMerge](http://huggingface.co/CultriX/SeQwence-14B-EvolMerge) especially, but a hefty list of other models as well.
Its reasoning and prose skills are quite strong. Version 0.3 is the product of a carefully planned and tested sequence of templated merges, produced by a toolchain which wraps around Arcee's mergekit.
For GGUFs, [mradermacher/Lamarck-14B-v0.3-i1-GGUF](https://huggingface.co/mradermacher/Lamarck-14B-v0.3-i1-GGUF) has you covered. Thank you @mradermacher!
**The merge strategy of Lamarck 0.3 can be summarized as:**
- Two model_stocks commence specialized branches for reasoning and prose quality.
- For refinement on both model_stocks, DELLA and SLERP merges re-emphasize selected ancestors.
- For smooth instruction following, a SLERP merged Virtuoso with converged branches.
- For finalization and normalization, a TIES merge.
### Thanks go to:
- @arcee-ai's team for the ever-capable mergekit, and the exceptional Virtuoso Small model.
- @CultriX for the helpful examples of memory-efficient sliced merges and evolutionary merging. Their contribution of tinyevals on version 0.1 of Lamarck did much to validate the hypotheses of the process used here.
- The authors behind the capable models that appear in the model_stock. The boost to prose quality is already noticeable.
### Models Merged:
**Top influences:** These ancestors are base models and present in the model_stocks, but are heavily re-emphasized in the DELLA and SLERP merges.
- **[arcee-ai/Virtuoso-Small](https://huggingface.co/arcee-ai/Virtuoso-Small)** - A brand new model from Arcee, refined from the notable cross-architecture Llama-to-Qwen distillation [arcee-ai/SuperNova-Medius](https://huggingface.co/arcee-ai/SuperNova-Medius). The first two layers are nearly exclusively from Virtuoso. It has proven to be a well-rounded performer, and contributes a noticeable boost to the model's prose quality.
- **[CultriX/SeQwence-14B-EvolMerge](http://huggingface.co/CultriX/SeQwence-14B-EvolMerge)** - A top contender on reasoning benchmarks.
**Reason:** While Virtuoso is the strongest influence the starting ending layers, the reasoning mo
- **[CultriX/Qwen2.5-14B-Wernicke](http://huggingface.co/CultriX/Qwen2.5-14B-Wernicke)** - A top performer for Arc and GPQA, Wernicke is re-emphasized in small but highly-ranked portions of the model.
- **[VAGOsolutions/SauerkrautLM-v2-14b-DPO](https://huggingface.co/VAGOsolutions/SauerkrautLM-v2-14b-DPO)** - This model's influence is understated, but aids BBH and coding capability.
**Prose:** While the prose module is gently applied, its impact is noticeable on Lamarck 0.3's prose quality, and a DELLA merge re-emphasizes the contributions of two models particularly:
- **[sthenno-com/miscii-14b-1028](https://huggingface.co/sthenno-com/miscii-14b-1028)**
- **[underwoods/medius-erebus-magnum-14b](https://huggingface.co/underwoods/medius-erebus-magnum-14b)**
**Model stock:** Two model_stock merges, specialized for specific aspects of performance, are used to mildly influence a large range of the model.
- **[sometimesanotion/lamarck-14b-reason-model_stock](https://huggingface.co/sometimesanotion/lamarck-14b-reason-model_stock)**
- **[sometimesanotion/lamarck-14b-prose-model_stock](https://huggingface.co/sometimesanotion/lamarck-14b-prose-model_stock)** - This brings in a little influence from [EVA-UNIT-01/EVA-Qwen2.5-14B-v0.2](https://huggingface.co/EVA-UNIT-01/EVA-Qwen2.5-14B-v0.2), [oxyapi/oxy-1-small](https://huggingface.co/oxyapi/oxy-1-small), and [allura-org/TQ2.5-14B-Sugarquill-v1](https://huggingface.co/allura-org/TQ2.5-14B-Sugarquill-v1).
**Note on abliteration:** This author believes that adjacent services and not language models themselves are where guardrails are best placed. Effort to de-censor Lamarck will resume after the model has been further studied.
