🚀 LLM Foundry v0.12.0

New Features

PyTorch 2.4 (#1505)

This release updates LLM Foundry to the PyTorch 2.4 release, bringing with it support for the new features and optimizations in PyTorch 2.4

Extensibility improvements (#1450, #1449, #1468, #1467, #1478, #1493, #1495, #1511, #1512, #1527)

Numerous improvements to the extensibility of the modeling and data loading code, enabling easier reuse for subclassing and extending. Please see the linked PRs for more details on each change.

Improved error messages (#1457, #1459, #1519, #1518, #1522, #1534, #1548, #1551)

Various improved error messages, making debugging user errors more clear.

Sliding window in torch attention (#1455)

We've added support for sliding window attention to the reference attention implementation, allowing easier testing and comparison against more optimized attention variants.

Bug fixes

Extra BOS token for llama 3.1 with completion data (#1476)

A bug resulted in an extra BOS token being added between prompt and response during finetuning. This is fixed so that the prompt and response supplied by the user are concatenated without any extra tokens put between them.

🚀 LLM Foundry v0.11.0

New Features

LLM Foundry CLI Commands (#1337, #1345, #1348, #1354)

We've added CLI commands for our commonly used scripts.

For example, instead of calling composer llm-foundry/scripts/train.py parameters.yaml, you can now do composer -c llm-foundry train parameters.yaml.

Docker Images Contain All Optional Dependencies (#1431)

LLM Foundry Docker images now have all optional dependencies.

Support for Llama3 Rope Scaling (#1391)

To use it, you can add the following to your parameters:

model:
    name: mpt_causal_lm
    attn_config:
      rope: true
      ...
      rope_impl: hf
      rope_theta: 500000
      rope_hf_config:
        type: llama3
        ...

Tokenizer Registry (#1386)

We now have a tokenizer registry so you can easily add custom tokenizers.

LoadPlanner and SavePlanner Registries (#1358)

We now have LoadPlanner and SavePlanner registries so you can easily add custom checkpoint loading and saving logic.

Faster Auto-packing (#1435)

The auto packing startup is now much faster. To use auto packing with finetuning datasets, you can add packing_ratio: auto to your config like so:

  train_loader:
    name: finetuning
    dataset:
      ...
      packing_ratio: auto

🚀 LLM Foundry v0.10.0

New Features

Registry for ICL datasets (#1252)

ICL datasets have now been added as a registry.

Curriculum Learning Callback (#1256)

You can now switch dataloaders while training which enables curriculum learning.

train_loader:
  <dataloader parameters>
callback:
  curriculum_learning:
  - duration: <number>tok
    train_loader:  # matches top level train_loader
      <dataloader parameters>
  - duration: <number>tok
    train_loader:
      <dataloader parameters>
  - duration: <number>tok
    train_loader:
      <dataloader parameters>

[Experimental] Interweave Attention Layers (#1299)

You can now override default block configs for certain layers, allowing for different sliding window sizes, reusing the previous layer's kv cache, etc.

model:
    ...
    (usual model configs)
    ...
    block_overrides:
        order:
        - name: default
        - order:
          - name: sliding_window_layer
          - name: sliding_window_layer_reuse
          - name: sliding_window_layer
          - repeat: 2
            name: sliding_window_layer_reuse
          - name: reuse_kv_layer
          repeat: 2
        overrides:
            sliding_window_layer:
                attn_config:
                    sliding_window_size: 1024
            sliding_window_layer_reuse:
                attn_config:
                    sliding_window_size: 1024
                    reuse_kv_layer_idx: -1 # Relative index of the layer whose kv cache to reuse
            reuse_kv_layer:
                attn_config:
                    reuse_kv_layer_idx: -6 # Relative index of the layer whose kv cache to reuse

🚀 LLM Foundry v0.9.0

New Features

More Token Encoding Types (#1254)

We've expanded the different ways to encode token IDs by allowing uint32 and uint16 formats, which saves significant space for datasets with smaller vocab sizes. We also extended ndarray type support for MDS dataset columns to the generic text dataset and updated conversion scripts accordingly.

Enforced Stricter Configs (#1254, #1225, #1202)

We've implemented stricter enforcement on our Train and Eval configs to further protect users from attempting to train with invalid configs. In conjunction with numerous other PRs, we have stronger error handling to help users use LLM Foundry smoothly.

Previously, this was allowed:

parameters:
   train_dataloader:
      ...
      seed: ${global_seed}
      random_other_key_that's_not_in_the_dataloader_constructor # this is not allowed
   ...
   global_seed: 17 # this is also not allowed

But we've added a variables section. Please do this instead:

parameters:
  variables:
    global_seed: 42
  ...
  train_dataloader:
    seed: ${variables.global_seed}

Chunked text to mds conversion (#1240)

We've updated our text to mds to convertion script to convert files to MDS in chunks. This protects us from loading entire large files at once (potentially causing OOMs), and drastically speeds up converting long sequences.

v0.7.0

🚀 LLM Foundry v0.7.0

LLM Foundry is an efficient codebase for training, evaluating, and deploying Large Language Models (LLMs) and serves as the foundation for the MPT model series.

In addition to the usual bug fixes and performance improvements, we've made foundry more customizable and extensible!

New Features

Registerable Components (#975, #1043, #1052, #1057)

We've made key components of LLM Foundry registrable, such as models, loggers, and callbacks. You can use the registry to easily customize and extend your training workflows.

This means that you can register new options for these components, and then use them in your yaml config.

Check out the README for detailed instructions and code examples!

Breaking Changes and Deprecations

Deprecated Feature Removals (#1063)

We've removed support for deprecated features: triton attention, Prefix LMs, Llama attention patch, z-loss, and text denoising. These features were little used, and we removed them to focus on the core features that are heavily used.

If you were using these features please let us know how you were using them in a GitHub issue. We're happy to add things back that are in heavy usage.

v0.6.0

🚀 LLM Foundry v0.6.0

LLM Foundry is an efficient codebase for training, evaluating, and deploying Large Language Models (LLMs) and serves as the foundation for the MPT model series.

In addition to the usual bug fixes and performance improvements, we've added lots of new features!

New Features

Configurable loss for chat-formatted data (#985)

For chat-formatted data, you can now specify which tokens should be loss-generating in a configurable way.

This can be specified in the train_loader.dataset section of your yaml as follows:

...
train_loader:
  dataset:
    ...
    target_prompts: <FILL IN>
    target_reseponses: <FILL IN>

See the docstring for a description of the options.

Olmo support (#1016)

We've added support for the OLMo model from AI2.

To use OLMo, there are a few configuration parameters you need to set. First of all, you will need to install LLM Foundry with the extra package for OLMo (pip install .[gpu,olmo]).

Then you will need to adjust the tokenizer section of your config as follows:

tokenizer:
  name: allenai/OLMo-7B
  kwargs:
    revision: main
    model_max_length: 2048
    model_input_names:
    - input_ids
    - attention_mask
    trust_remote_code: true

Token accuracy (#983)

We've added a new, on-by-default metric to compute token accuracy in addition to cross entropy and perplexity.

Configurable activation checkpointing (#951)

More configurable activation checkpointing for MPT allows finer granular control over memory usage when training MPT. See the docstring for more details.

Finetuning with multiple streams, and pretokenized data (#933, #945, #946)

We've brought the finetuning dataloader up to speed with the pretraining dataloader to support mixing multiple streams, and pretokenizing finetuning data. See the yaml for a full example.

Eval Gauntlet v0.3 (#824)

We've release v0.3 of our Evaluation gauntlet. See the README for a full description.

Breaking changes and deprecations

Flash attention v1 removal (#1023)

Support for flash attention v1 has now been removed.

Extra BOS token removed (#1003)

When tokenizing prompt/response and chat data, for some tokenizers, we were mistakenly adding an extra BOS token between the prompt and the response. This has now been removed.

Deprecation of triton flash attention, prefixLM, and text denoising (#1007)

We've deprecated use of the triton version of flash attention, prefixLM, and text denoising, as these features were not heavily used or actively maintained.

🚀 LLM Foundry v0.5.0

LLM Foundry is an efficient codebase for training, evaluating, and deploying Large Language Models (LLMs) and serves as the foundation for the MPT model series.

In addition to the usual bug fixes and performance improvements, we've added lots of new features!

New Features

LoRA Support (with FSDP!) (#886)

LLM Foundry now supports LoRA via an integration with the PEFT library. Within LLM Foundry, run train.py, adding peft_config arguments to the model section of the config .yaml, like so:

model:
  ...
  peft_config:
      r: 16
      peft_type: LORA
      task_type: CAUSAL_LM
      lora_alpha: 32
      lora_dropout: 0.05
      target_modules:
      - q_proj
      - k_proj

Read more about it in the tutorial.

ALiBi for Flash Attention (#820)

We've added support for using ALiBi with Flash Attention (v2.4.2 or higher).

model:
     ...
     attn_config:
         attn_impl: flash
         alibi: True

Chat Data for Finetuning (#884)

We now support finetuning on chat data, with automatic formatting applied using Hugging Face tokenizer chat templates.

Each sample requires a single key "messages" that maps to an array of message objects. Each message object in the array represents a single message in the conversation and must contain the following keys:

  • role : A string indicating the author of the message. Possible values are "system" ,"user" , and "assistant" .
  • content : A string containing the text of the message.

We require that there must be at least one message with the role "assistant", and the last message in the "messages" array must have the role "assistant" .

Here's an example .jsonl with chat data:


{ "messages": [ { "role": "user", "content": "Hi, MPT!" }, { "role": "assistant", "content": "Hi, user!" } ]}
{ "messages": [ 
  { "role": "system": "A conversation between a user and a helpful and honest assistant"}
  { "role": "user", "content": "Hi, MPT!" }, 
  { "role": "assistant", "content": "Hi, user!" },
  { "role": "user", "content": "Is multi-turn chat supported?"},
  { "role": "assistant", "content": "Yes, we can chat for as long as my context length allows." }
]}
...

Safe Load for HuggingFace Datasets (#798)

We now provide a safe_load option when loading HuggingFace datasets for finetuning.

This restricts loaded files to .jsonl, .csv, or .parquet extensions to prevent arbitrary code execution.

To use, set safe_load to true in your dataset configuration:

  train_loader:
    name: finetuning
    dataset:
      safe_load: true
      ...

New PyTorch, Composer, Streaming, and Transformers versions

As always, we've updated to new versions of the core dependencies of LLM Foundry, bringing better performance, new features, and support for new models (mixtral in particular).

Deprecations

Support for Flash Attention v1 (#921)

Will be removed in v0.6.0.

Breaking Changes

Removed support for PyTorch versions before 2.1 (#787)

We no longer support PyTorch versions before 2.1.

Removed Deprecated Features (#948)

We've removed features that have been deprecated for at least one release.

v0.4.0

🚀 LLM Foundry v0.4.0

LLM Foundry is an efficient codebase for training, evaluating, and deploying Large Language Models (LLMs) and serves as the foundation for the MPT-7B and MPT-30B models.

In addition to the usual bug fixes and performance improvements, we've added lots of new features!

New Features

Automatic sequence packing (#683)

You can now specify packing_ratio: auto under your finetuning dataset, to automatically profile and select a good packing ratio to efficiently pack your sequences together on the fly during finetuning. This can dramatically reduce the amount of compute wasted on padding tokens.

Flash Attention 2 (#651, #666, #672)

We now support using Flash Attention 2 both in MPT and in any model that supports Flash Attention 2 via the Transformers library. See the training instructions to learn how to use the different versions of Flash Attention.

New PyTorch, Composer, Streaming, and Transformers versions (#648, #672, #736)

As always, we've updated to new versions of the core dependencies of LLM Foundry, bringing better performance, new features, and support for new models (codellama and mistral in particular).

Easy Databricks model deployment (#618)

We've made it much easier to go from a training run to a served model using Databricks model serving. To make use of this feature, you need to specify both an MLFlowLogger and a HuggingFaceCheckpointer for your run.

The MLFlowLogger should have a Unity Catalog model registry prefix in the form of catalog.schema. This specifies where to register your models to. For example,

loggers:
    mlflow:
        experiment_name: /Users/first.last@email.com/my_experiment_name
        tracking_uri: databricks
        model_registry_prefix: catalog.schema
        model_registry_uri: databricks-uc

The HuggingFaceCheckpointer should specify the name you want to register the model under. For example,

callbacks:
    hf_checkpointer:
        save_interval: 1ep # Save Hugging Face formatted checkpoints each epoch
        save_folder: s3://bucket/path/to/my/checkpoints
        mlflow_registered_model_name: my_model_name # Final model will be registered to catalog.schema.my_model_name

MPT model configurations

We've added a few new options when training with the MPT architecture in LLM Foundry.

  • Rotary embeddings (#675)
  • (Un)Tied word embeddings (#728)
  • Fine grained activation checkpointing (#720)

Evaluation Improvements

We've released v0.1 of our Eval Gauntlet (#674, #748)! This adds many new benchmarks, chain-of-thought, and a new safety category. Check out the README for full details!

In addition, we've made a few improvements to our evaluation options, with more to come!

  • Allow specifying multiple evaluation datasets to compute cross entropy and perplexity on during training (#603)
  • Easier versions of the HumanEval dataset, which can be useful for comparing smaller models (#645)
  • More options for averaging the results of the Eval Gauntlet (#640)

New pretraining benchmarks (#543)

Added H100 profiling results to our benchmarking table.

Quality of life improvements

  • Improved Generate callback with more logging options. Use the Generate callback to log generations from your model over the course of training. (#631)
  • Count number of tokens during training excluding padding tokens. Previously this count included padding tokens. (#676)
  • Use the PyTorch profiler to profile your training runs. (#678)
  • A convenience script for using the much faster Hugging Face snapshot_download to download models from the Hugging Face Hub. (#708)
  • New AWS specific Docker images with LLM Foundry dependencies pre-installed. (#731)

Experimental features

Inverse square root learning rate scheduler (#657)

We've added experimental support for the inverse square root learning rate scheduler.

Breaking changes

Updated Streaming defaults (#723)

We've upgraded to the latest Streaming version, including vastly improved default settings for partitioning and shuffling. This means that if you were using the defaults, you will get different results after upgrading. The new defaults should be more performant for the large majority of use cases. See the Streaming release notes for more details.

Removed support for PrefixLM for Bloom and OPT models (#704)

We occasionally remove unused experimental parts of the code base to focus on new features and better support for existing features, and we've removed support for PrefixLM applied to Bloom and OPT models in this release.
