What it is

Flare is a dynamic tensor graph library written in Clojure, offering flexibility and power similar to PyTorch or DynNet. It's ideal for developers looking to leverage the functional programming benefits of Clojure while working on deep learning projects.

Flare stands out as the only deep learning framework that integrates seamlessly with Clojure, offering developers the unique ability to leverage functional programming principles in their AI projects.

When it fits — and when it doesn’t

A good fit for

  • Developers who prefer the functional programming paradigm in their deep learning projects

  • Teams working on research and prototyping with a preference for Clojure

  • Projects that require dynamic tensor graph construction capabilities

Look elsewhere if

  • Teams requiring real-time streaming or high-frequency data processing (Flare's focus is more on flexibility than performance optimization)

  • Developers looking for a wide range of pre-built models and extensive community support (as Flare is niche)

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support

    Flare is primarily written in Clojure, which has a smaller community compared to Python or other mainstream languages used for deep learning.

  2. 02

    Complex setup and configuration

    Setting up Flare requires familiarity with the Leiningen build tool and managing dependencies within the Clojure ecosystem, which can be challenging for developers new to Clojure.

  3. 03

    Smaller community and limited third-party integrations

    The smaller user base of Flare means fewer community contributions, tutorials, and third-party libraries compared to more popular frameworks like PyTorch or TensorFlow.

  4. 04

    Performance overhead due to Clojure's dynamic nature

    Clojure is a dynamically typed language which can introduce performance penalties in comparison to statically-typed alternatives commonly used for deep learning tasks.

What it does well

  • Dynamic tensor graph construction

  • Functional programming paradigm in Clojure

  • Flexibility similar to PyTorch or DynNet
