Ailiance — Devstral-Small-2-24B-BF16 kicad-pcb (fullseq) LoRA

LoRA adapter fine-tuned on mistralai/Devstral-Small-2-24B-Instruct-2512 for kicad-pcb tasks.

Variant: trained with full-sequence loss for stronger schema adherence.

Maintained by Ailiance — French AI org publishing EU AI Act aligned LoRA adapters and datasets.

ATTRIBUTION AUDIT COMPLETED

The training dataset Ailiance-fr/mascarade-kicad-dataset went through a full Stack Exchange attribution audit (2026-05-11): 61 samples (2.3%) carry per-sample URL+author+post_id attribution; 169 samples flagged not_found_on_se (likely synthetic); 2 413 samples (91%) are LLM-synthetic. Audit report: docs/audit_mascarade_se_attribution.md in electron-bench.

Quick start (MLX)

from mlx_lm import load, generate

    "mistralai/Devstral-Small-2-24B-Instruct-2512",
    adapter_path="Ailiance-fr/devstral-kicad-pcb-fullseq-lora",
)

print(generate(model, tokenizer, prompt="..."))

Benchmark roadmap

This LoRA has not yet been evaluated through electron-bench (the current pipeline supports gemma-4-E4B base only). Training was completed with the standard mlx-lm LoRA trainer (rank 16, alpha 32, scale 2.0, AdamW LR 1e-5, 500 iters) — full hyperparameters are in the Training table above.

Planned evaluations:

• Perplexity on the validation split of the training data
• Functional benchmark on devstral-specific tasks
• Comparison vs base mistralai/Devstral-Small-2-24B-Instruct-2512

Track progress: ailiance-bench issues.
