Provides a single configuration-driven interface to fine-tune 100+ model families (LLaMA, Qwen, GLM, Mistral, Gemma, Yi, DeepSeek, etc.) by abstracting model-specific loading logic through a centralized model registry and adapter system. The framework uses HuggingFace Transformers as the base loader, then applies model-specific patches and configurations via a modular patching system that handles architecture variations, attention mechanisms, and special token handling without requiring separate codebases per model.
Unique: Uses a centralized model registry with model-specific patching system (in model_utils/) that applies architecture-aware modifications at load time, enabling single codebase to handle 100+ models without forking logic per model family. Contrasts with alternatives like Hugging Face's native approach which requires per-model integration.
vs alternatives: Supports 100+ models through unified config vs. alternatives like Axolotl or Lit-GPT which require separate configs/code per model family, reducing maintenance burden for multi-model deployments.
Implements multiple parameter-efficient fine-tuning (PEFT) methods through a pluggable adapter architecture that wraps model layers without modifying base weights. Supports LoRA (low-rank decomposition), QLoRA (quantized LoRA for 4-bit models), and OFT (orthogonal fine-tuning) by integrating with HuggingFace PEFT library and extending it with custom implementations. The adapter system allows selective application to specific layer types (attention, MLP) and supports merging adapters back into base weights or keeping them separate for inference.
Unique: Integrates HuggingFace PEFT as base layer but extends with custom OFT implementation and model-specific adapter target selection logic that automatically identifies which layers to adapt based on model architecture, reducing manual configuration. Supports dynamic adapter merging/unmerging during inference via the adapter system.
vs alternatives: Unified adapter interface supporting LoRA, QLoRA, and OFT with automatic layer targeting vs. alternatives like Hugging Face's native PEFT which requires manual target_modules specification and lacks OFT support.
Enables exporting fine-tuned models and adapters in multiple formats (PyTorch, SafeTensors, GGUF, GPTQ) and merging adapters back into base model weights for deployment. The export system handles format conversion, quantization during export (e.g., exporting to GPTQ format), and adapter merging which combines LoRA weights with base model weights through a weighted sum operation. Supports exporting to HuggingFace Hub for easy sharing, and includes format-specific optimizations (e.g., GGUF export includes quantization and can target specific hardware like CPU or mobile).

Integrates custom optimizers (GaLore, BAdam, APOLLO) that improve training efficiency beyond standard Adam by reducing memory usage or improving convergence. GaLore (Gradient Low-Rank Projection) projects gradients into a low-rank subspace, reducing optimizer state memory by 50-70%. BAdam (Block-wise Adam) partitions parameters into blocks and maintains separate optimizer states per block, improving convergence on large models. APOLLO applies adaptive learning rates per parameter group. These optimizers are pluggable through the training system and can be selected via configuration.
Unique: Integrates 3 advanced optimizers (GaLore, BAdam, APOLLO) as pluggable alternatives to Adam/AdamW, with automatic memory and convergence tracking. Each optimizer is selectable via configuration without code changes.

Provides a flexible dataset loading system that supports 50+ dataset formats (Alpaca, ShareGPT, OpenAI, JSONL, CSV, Parquet, etc.) through a template-based approach that maps raw data to standardized training formats. Each dataset format has a corresponding template that defines how to extract instruction, input, output, and history fields from the raw data. The system handles dataset discovery (from HuggingFace Hub or local paths), automatic format detection, and data validation. Custom templates can be defined in YAML to support new formats without code changes.
Unique: Implements a template-based dataset loading system supporting 50+ formats through YAML templates that map raw data to standardized training formats. Custom templates can be defined without code changes, enabling support for arbitrary dataset structures.
vs alternatives: Template-based dataset loading supporting 50+ formats vs. alternatives like Hugging Face's native approach which requires custom data loading scripts, reducing boilerplate for multi-format datasets.
Integrates training callbacks that track metrics, log to external services (TensorBoard, Weights & Biases, Wandb), and trigger custom actions during training. The callback system hooks into the training loop at key points (step, epoch, validation) and enables custom metric computation, early stopping, learning rate scheduling, and model checkpointing. Built-in callbacks include loss tracking, gradient norm monitoring, learning rate logging, and stage-specific metrics (e.g., reward model accuracy, PPO policy divergence). Custom callbacks can be defined by extending a base class.
Unique: Integrates multiple logging backends (TensorBoard, Weights & Biases) through a unified callback system with stage-specific metrics (e.g., reward model accuracy, PPO divergence). Custom callbacks can be defined by extending a base class.
vs alternatives: Unified callback system supporting multiple logging backends vs. Hugging Face Trainer which requires separate integrations, enabling easier experiment tracking across tools.
Orchestrates sequential training stages (pre-training, supervised fine-tuning, reward modeling, PPO, DPO, KTO, ORPO, SimPO) through a stage-aware trainer system that swaps loss functions, data collators, and optimization strategies based on the selected training_stage parameter. Each stage has a dedicated trainer class (SFTTrainer, RewardTrainer, PPOTrainer, etc.) that inherits from HuggingFace Trainer and implements stage-specific logic like preference pair handling for reward models or policy gradient computation for PPO. The configuration system validates stage transitions and manages data format expectations per stage.
Unique: Implements 8 distinct training stages (SFT, RM, PPO, DPO, KTO, ORPO, SimPO) through a unified trainer abstraction that swaps loss functions and data collators per stage, with automatic data format validation. Extends HuggingFace Trainer with stage-specific callbacks for metrics tracking (e.g., reward model accuracy, PPO policy divergence).
vs alternatives: Supports 8 alignment methods in one framework vs. alternatives like TRL (which focuses on PPO) or Axolotl (which has limited DPO/ORPO support), enabling direct comparison of alignment approaches without switching tools.
Centralizes all training, inference, and data parameters through a unified configuration parser (hparams/parser.py) that accepts YAML/JSON files and validates inputs against typed argument classes (ModelArguments, DataArguments, TrainingArguments, etc.). The parser converts flat configuration dictionaries into strongly-typed Python dataclasses, performs cross-field validation (e.g., ensuring adapter_name_or_path exists if adapter_type is set), and distributes validated arguments to the appropriate subsystems. This eliminates the need for command-line argument parsing and enables reproducible training via version-controlled config files.
Unique: Implements a centralized parser that validates all 5 argument types (Model, Data, Training, Generation, Finetuning) against typed dataclasses with cross-field validation logic, enabling single source of truth for configuration. Supports both YAML and JSON with automatic format detection and command-line override capability.
vs alternatives: Unified config validation across all subsystems vs. alternatives like Hugging Face Trainer which requires separate argument parsing, reducing configuration errors and improving reproducibility.
