the field guide

The model atlas

Every open model is a specimen — read · named · placed among its kin. A base model is a champion; its finetunes are builds off it; what Ardora read, drawn as a shape, is its Silhouette. Where the read couldn't see clearly, it abstains, and the blank is published as loudly as the reading.

Every champion, and the builds off it

Each family is a champion and its builds. The colour is the family; the little bars are the champion's stat shape across Ardora's seven published axes; the glyph is a build's disposition class. Open a champion for its full field-note, or a family for the plate.

SmolLM2 family

Llama · Hugging Face (HuggingFaceTB) · 6 shown · 6 readBaseARDORA READ · 2026-07-05stat shape

Across the size sweep (135M -> 360M -> 1.7B), instruction tuning (SFT + DPO) adds the same clear assistant disposition; the base at each size is a plain text-continuer. Open the family plate →

Qwen3 family

Qwen3 · Alibaba (Qwen Team) & mlabonne (abliteration finetune) · 5 shown · 5 readBaseARDORA READ · 2026-07-05stat shape

Post-training turns the base text-continuer into a chat model that also carries a switchable reasoning (thinking) register; the assistant shift reads clearly across the 0.6B and 1.7B sizes. Open the family plate →

Pythia family

GPT-NeoX · EleutherAI (bases) & lomahony (SFT finetunes) · 5 shown · 5 readBaseARDORA READ · 2026-07-06stat shape

Llama 3.2 (1B) family

Llama · Meta (via unsloth mirror), huihui-ai (abliteration uncensor), Carsen Klock (data-SFT uncensor), prithivMLmods (math), yingfanbot (GSM8K math) & Skywork (reward model) · 7 shown · 7 read protora finding in this familyBaseARDORA READ · 2026-07-06stat shape

Instruction tuning turns the Llama-3.2-1B base (a plain continuer) into an assistant that follows instructions and holds a chat register; the shift reads clearly. Open the family plate →

OLMo-2 (1B) family

OLMo-2 · Allen Institute for AI (Ai2) · 4 shown · 4 readBaseARDORA READ · 2026-07-05stat shape

A rare fully-labeled post-training lineage: Ai2's OLMo-2 1B publishes its base and all three sequential post-training stages (SFT -> DPO -> RLVR/Instruct), so the atlas can walk the chain… Open the family plate →

Every field-note here began as a patient read, carried a replayable witness, and left an honest blank for whatever stayed in shadow.
