AITraining is an advanced machine learning training platform built on top of AutoTrain Advanced. It provides a streamlined interface for fine-tuning LLMs, vision models, and more.

Highlights

Automatic Dataset Conversion

Feed any dataset format and AITraining automatically detects and converts it. Supports 6 input formats with automatic detection:

Format	Detection	Example Columns
Alpaca	instruction/input/output	{"instruction": "...", "output": "..."}
ShareGPT	from/value pairs	{"conversations": [{"from": "human", ...}]}
Messages	role/content	{"messages": [{"role": "user", ...}]}
Q&A	question/answer variants	{"question": "...", "answer": "..."}
DPO	prompt/chosen/rejected	For preference training
Plain Text	Single text column	Raw text for pretraining

aitraining llm --train --auto-convert-dataset --chat-template gemma3 \
  --data-path tatsu-lab/alpaca --model google/gemma-3-270m-it

32 Chat Templates

Comprehensive template library with token-level weight control:

• Llama family: llama, llama-3, llama-3.1
• Gemma family: gemma, gemma-2, gemma-3, gemma-3n
• Others: mistral, qwen-2.5, phi-3, phi-4, chatml, alpaca, vicuna, zephyr

from autotrain.rendering import get_renderer, ChatFormat, RenderConfig

config = RenderConfig(format=ChatFormat.CHATML, only_assistant=True)
renderer = get_renderer('chatml', tokenizer, config)
encoded = renderer.build_supervised_example(conversation)
# Returns: {'input_ids', 'labels', 'token_weights', 'attention_mask'}

GRPO Training with Custom Environments

Train with Group Relative Policy Optimization using your own reward environment. The env provides prompts and scores multi-turn episodes — GRPO generates completions, scores them, and optimizes:

aitraining llm --train --trainer grpo \
  --model deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B \
  --rl-env-module my_envs.hotel_env \
  --rl-env-class HotelEnv \
  --rl-num-generations 4 \
  --rl-max-new-tokens 256

Your environment implements three methods:

class HotelEnv:
    def build_dataset(self, tokenizer) -> Dataset:
        """Return HF Dataset with 'prompt' column."""

    def score_episode(self, model, tokenizer, completion, case_idx) -> float:
        """Run multi-turn episode from completion, return 0.0-1.0 score."""

    def get_tools(self) -> list[dict]:
        """Return tool schemas for generation (optional)."""

Custom RL Environments (PPO)

Build custom reward functions for PPO training with three environment types:

# Text generation with custom reward
aitraining llm --train --trainer ppo \
  --rl-env-type text_generation \
  --rl-env-config '{"stop_sequences": ["</s>"]}' \
  --rl-reward-model-path ./reward_model

# Multi-objective rewards (correctness + formatting)
aitraining llm --train --trainer ppo \
  --rl-env-type multi_objective \
  --rl-env-config '{"reward_components": {"correctness": {"type": "keyword"}, "formatting": {"type": "length"}}}' \
  --rl-reward-weights '{"correctness": 1.0, "formatting": 0.1}'

Hyperparameter Sweeps

Automated optimization with Optuna, random search, or grid search:

from autotrain.utils import HyperparameterSweep, SweepConfig, ParameterRange

config = SweepConfig(
    backend="optuna",
    optimization_metric="eval_loss",
    optimization_mode="minimize",
    num_trials=20,
)

sweep = HyperparameterSweep(
    objective_function=train_model,
    config=config,
    parameters=[
        ParameterRange("learning_rate", "log_uniform", low=1e-5, high=1e-3),
        ParameterRange("batch_size", "categorical", choices=[4, 8, 16]),
    ]
)
result = sweep.run()
# Returns best_params, best_value, trial history

Enhanced Evaluation Metrics

8 metrics beyond loss, with callbacks for periodic evaluation:

Metric	Type	Use Case
Perplexity	Auto-computed	Language model quality
BLEU	Generation	Translation, summarization
ROUGE (1/2/L)	Generation	Summarization
BERTScore	Generation	Semantic similarity
METEOR	Generation	Translation
F1/Accuracy	Classification	Standard metrics
Exact Match	QA	Question answering

from autotrain.evaluation import Evaluator, EvaluationConfig, MetricType

config = EvaluationConfig(
    metrics=[MetricType.PERPLEXITY, MetricType.BLEU, MetricType.ROUGE, MetricType.BERTSCORE],
    save_predictions=True,
)
evaluator = Evaluator(model, tokenizer, config)
result = evaluator.evaluate(dataset)

Auto LoRA Merge

After PEFT training, automatically merge adapters and save deployment-ready models:

# Default: merges adapters into full model
aitraining llm --train --peft --model meta-llama/Llama-3.2-1B

# Keep adapters separate (smaller files)
aitraining llm --train --peft --no-merge-adapter --model meta-llama/Llama-3.2-1B

Quick Start

Interactive Wizard

aitraining

The wizard guides you through:

1. Trainer type selection (LLM, vision, NLP, tabular)
2. Model selection with curated catalogs from HuggingFace
3. Dataset configuration with auto-format detection
4. Advanced parameters (PEFT, quantization, sweeps)

Config File

aitraining --config config.yaml

Python API

from autotrain.trainers.clm import train
from autotrain.trainers.clm.params import LLMTrainingParams

config = LLMTrainingParams(
    model="meta-llama/Llama-3.2-1B",
    data_path="your-dataset",
