ℹ️ About

Aim is an open-source, self-hosted AI Metadata tracking tool designed to handle 100,000s of tracked metadata sequences.

Aim provides a performant and beautiful UI for exploring and comparing metadata such as training runs or agents executions. Additionally, its SDK enables programmatic access to tracked metadata — perfect for automations and Jupyter Notebook analysis.

Aim's mission is to democratize AI dev tools 🎯

🔮 Aim 4.0

Aim 4.0 is coming soon!!

A major iteration of Aim as the ultimate metadata library to track all your interactions with your models - including experiments, prompts etc.

Remote first
Scalable
Capable of storing and querying 100,000s of metadata sequences
Custom UI dashboards and reports

The Aim experiment tracker is not just one-off experiment tracker. It's built on top of the metadata library that Aim is. Now you can also do prompt engineering on Aim. Stay tuned for more...

🏁 Quick start

Follow the steps below to get started with Aim.

1. Install Aim on your training environment

pip3 install aim

2. Integrate Aim with your code

from aim import Run

# Initialize a new run
run = Run()

# Log run parameters
run["hparams"] = {
    "learning_rate": 0.001,
    "batch_size": 32,
}

# Log metrics
for i in range(10):
    run.track(i, name='loss', step=i, context={ "subset":"train" })
    run.track(i, name='acc', step=i, context={ "subset":"train" })

See the full list of supported trackable objects(e.g. images, text, etc) here.

3. Run the training as usual and start Aim UI

Migrate from other tools

Aim has built-in converters to easily migrate logs from other tools. These migrations cover the most common usage scenarios. In case of custom and complex scenarios you can use Aim SDK to implement your own conversion script.

Integrate Aim into an existing project

Aim easily integrates with a wide range of ML frameworks, providing built-in callbacks for most of them.

Query runs programmatically via SDK

Aim Python SDK empowers you to query and access any piece of tracked metadata with ease.

from aim import Repo

my_repo = Repo('/path/to/aim/repo')

query = "metric.name == 'loss'" # Example query

# Get collection of metrics
for run_metrics_collection in my_repo.query_metrics(query).iter_runs():
    for metric in run_metrics_collection:
        # Get run params
        params = metric.run[...]
        # Get metric values
        steps, metric_values = metric.values.sparse_numpy()

Set up a centralized tracking server

Aim remote tracking server allows running experiments in a multi-host environment and collect tracked data in a centralized location.

See the docs on how to set up the remote server.

🆚 Comparisons to familiar tools

TensorBoard vs Aim

Training run comparison

Order of magnitude faster training run comparison with Aim

The tracked params are first class citizens at Aim. You can search, group, aggregate via params - deeply explore all the tracked data (metrics, params, images) on the UI.
With tensorboard the users are forced to record those parameters in the training run name to be able to search and compare. This causes a super-tedius comparison experience and usability issues on the UI when there are many experiments and params. TensorBoard doesn't have features to group, aggregate the metrics.

Scalability

Aim is built to handle 1000s of training runs - both on the backend and on the UI.
TensorBoard becomes really slow and hard to use when a few hundred training runs are queried / compared.

MLflow vs Aim

MLFlow is an end-to-end ML Lifecycle tool. Aim is focused on training tracking. The main differences of Aim and MLflow are around the UI scalability and run comparison features.

Aim and MLflow are a perfect match - check out the aimlflow - the tool that enables Aim superpowers on MLflow.

Run comparison

Aim treats tracked parameters as first-class citizens. Users can query runs, metrics, images, and filter using the params.
MLFlow does have a search by tracked config, but there are no grouping, aggregation, subplotting by hyperparams and other comparison features available.

UI Scalability

Aim UI can handle several thousands of metrics at the same time smoothly with 1000s of steps. It may get shaky when you explore 1000s of metrics with 10000s of steps each. But we are constantly optimizing!
MLflow UI becomes slow to use when there are a few hundreds of runs.

Weights and Biases vs Aim

Hosted vs self-hosted

Weights and Biases is a hosted closed-source MLOps platform.
Aim is self-hosted, free, and open-source experiment tracking tool.
