This guide will walk you through your first model fine-tuning project with Axolotl.
## Quick Example {#sec-quick-example}
Let's start by fine-tuning a small language model using LoRA. This example uses a 1B parameter model to ensure it runs on most GPUs.
Assuming `axolotl` is installed (if not, see our [Installation Guide](installation.qmd))
1. Download example configs:
```shell
axolotl fetch examples
```
2. Run the training:
```shell
axolotl train examples/llama-3/lora-1b.yml
```
That's it! Let's understand what just happened.
## Understanding the Process {#sec-understanding}
### The Configuration File {#sec-config}
The YAML configuration file controls everything about your training. Here's what (part of) our example config looks like:
```yaml
base_model: NousResearch/Llama-3.2-1B
# hub_model_id: username/custom_model_name
datasets:
- path: teknium/GPT4-LLM-Cleaned
type: alpaca
dataset_prepared_path: last_run_prepared
val_set_size: 0.1
output_dir: ./outputs/lora-out
adapter: lora
lora_model_dir:
```
See our [Config options](config.qmd) for more details.
### Training {#sec-training}
When you run `axolotl train`, Axolotl:
1. Downloads the base model
2. (If specified) applies LoRA adapter layers
3. Loads and processes the dataset
4. Runs the training loop
5. Saves the trained model and / or LoRA weights
## Your First Custom Training {#sec-custom}
Let's modify the example for your own data:
1. Create a new config file `my_training.yml`:
```yaml
base_model: NousResearch/Nous-Hermes-llama-1b-v1
adapter: lora
# Training settings
micro_batch_size: 2
num_epochs: 3
learning_rate: 0.0003
# Your dataset
datasets:
- path: my_data.jsonl # Your local data file
type: alpaca # Or other format
```
This specific config is for LoRA fine-tuning a model with instruction tuning data using
the `alpaca` dataset format, which has the following format:
```json
{
"instruction": "Write a description of alpacas.",
"input": "",
"output": "Alpacas are domesticated South American camelids..."
}
```
Please see our [Dataset Formats](dataset-formats) for more dataset formats and how to
format them.
2. Prepare your JSONL data in the specified format (in this case, the expected `alpaca
format):
```json
{"instruction": "Classify this text", "input": "I love this!", "output": "positive"}
{"instruction": "Classify this text", "input": "Not good at all", "output": "negative"}
```
Please consult the supported [Dataset Formats](dataset-formats/) for more details.
3. Run the training:
```shell
axolotl train my_training.yml
```
## Common Tasks {#sec-common-tasks}
### Testing Your Model {#sec-testing}
After training, test your model:
```shell
axolotl inference my_training.yml --lora-model-dir="./outputs/lora-out"
```
### Preprocessing Data {#sec-preprocessing}
For large datasets, preprocess first:
```shell
axolotl preprocess my_training.yml
```
### Using a UI {#sec-ui}
Launch a Gradio interface:
```shell
axolotl inference my_training.yml --lora-model-dir="./outputs/lora-out" --gradio
```
## Next Steps {#sec-next-steps}
Now that you have the basics, you might want to:
- Try different model architectures
- Experiment with hyperparameters
- Use more advanced training methods
- Scale up to larger models
Check our other guides for details on these topics:
- [Configuration Guide](config.qmd) - Full configuration options
- [Dataset Formats](dataset-formats) - Working with different data formats
- [Multi-GPU Training](multi-gpu.qmd)

Tokenization mismatches between training and inference are a common source of problems.
:::
To debug:

```{.bash}
axolotl preprocess your_config.yml --debug
```
2. Verify inference tokenization by decoding tokens before model input
3. Compare token IDs between training and inference
### Special Tokens {#sec-special-tokens}
Configure special tokens in your YAML:
```{.yaml}
special_tokens:
bos_token: "<s>"
eos_token: "</s>"
unk_token: "<unk>"
tokens:

- "<|im_end|>"
```
## Troubleshooting {#sec-troubleshooting}
### Common Problems {#sec-common-problems}
::: {.panel-tabset}
## Memory Issues
- Use 8-bit loading
- Reduce batch sizes
- Try CPU offloading
## Token Issues

This guide covers advanced training configurations for multi-GPU setups using Axolotl.
## Overview {#sec-overview}
Axolotl supports several methods for multi-GPU training:
- DeepSpeed (recommended)
- FSDP (Fully Sharded Data Parallel)
- FSDP + QLoRA
## DeepSpeed {#sec-deepspeed}
DeepSpeed is the recommended approach for multi-GPU training due to its stability and performance. It provides various optimization levels through ZeRO stages.
### Configuration {#sec-deepspeed-config}
Add to your YAML config:
```{.yaml}
deepspeed: deepspeed_configs/zero1.json
```
### Usage {#sec-deepspeed-usage}
```{.bash}
accelerate launch -m axolotl.cli.train examples/llama-2/config.yml --deepspeed deepspeed_configs/zero1.json
```
### ZeRO Stages {#sec-zero-stages}
We provide default configurations for:
- ZeRO Stage 1 (`zero1.json`)
- ZeRO Stage 2 (`zero2.json`)
- ZeRO Stage 3 (`zero3.json`)
Choose based on your memory requirements and performance needs.
## FSDP {#sec-fsdp}
### Basic FSDP Configuration {#sec-fsdp-config}
```{.yaml}
fsdp:
- full_shard
- auto_wrap
fsdp_config:
fsdp_offload_params: true
fsdp_state_dict_type: FULL_STATE_DICT
fsdp_transformer_layer_cls_to_wrap: LlamaDecoderLayer
```
### FSDP + QLoRA {#sec-fsdp-qlora}
For combining FSDP with QLoRA, see our [dedicated guide](fsdp_qlora.qmd).
## Performance Optimization {#sec-performance}
### Liger Kernel Integration {#sec-liger}
::: {.callout-note}
Liger Kernel provides efficient Triton kernels for LLM training, offering:
- 20% increase in multi-GPU training throughput
- 60% reduction in memory usage
- Compatibility with both FSDP and DeepSpeed
:::
Configuration:
```{.yaml}
plugins:
- axolotl.integrations.liger.LigerPlugin
liger_rope: true
liger_rms_norm: true
liger_glu_activation: true
liger_layer_norm: true
liger_fused_linear_cross_entropy: true
```
## Troubleshooting {#sec-troubleshooting}
### NCCL Issues {#sec-nccl}
For NCCL-related problems, see our [NCCL troubleshooting guide](nccl.qmd).
### Common Problems {#sec-common-problems}
::: {.panel-tabset}
## Memory Issues
- Reduce `micro_batch_size`
- Reduce `eval_batch_size`
- Adjust `gradient_accumulation_steps`
- Consider using a higher ZeRO stage
## Training Instability
- Start with DeepSpeed ZeRO-2
- Monitor loss values
- Check learning rates
