NEXUS SFT Mix

Dataset SFT optimise pour NEXUS (234M params, programming + trading + conversation).

Format NEXUS v1

Chaque sample suit ce schema (compatible TRL/Axolotl/Unsloth via , enrichi avec curriculum metadata):

Sources

Mix combine ~4M samples de sources publiques curees:

Code (50%): nvidia/OpenCodeInstruct, Magicoder-OSS/Evol, Ling-Coder-SFT, rStar-Coder, Code-290k-ShareGPT
Code Reasoning (15%): Nemotron-Competitive-Programming-v2, open-r1/codeforces

General Instruction (5%): mlabonne/open-perfectblend

Curation Pipeline

NEXUS (pretrain step_423500) joue le role de curator auto:

Perplexity scoring -> garde samples qui apprennent au modele
Embeddings natifs -> dedup semantique cross-source
Decontamination -> check vs HumanEval/MBPP/MATH/GSM8K
Domain classification -> confirme tags via logits internes
