The Fifth Elephant Open Source AI Hackathon started on 5 January 2024 and reached its finale with a Demo Day event on 12 April 2024, when the winners of the two month long contest were chosen.

The aim of this hackathon was to encourage individuals/teams to apply and incubate innovative AI ideas/use cases and publish them as open source projects.

  • The hackathon contest participants worked with mentors for over two months to refine their ideas, and advance them to a stage where they are viable projects that could be pursued beyond the hackathon.
  • the project teams worked on AI’s application in education, accessibility, creative expression, scientific research, languages, under the overall theme of AI for India.
  • competing projects were judged on impact and relevance, innovation and creativity, technical soundness and code quality, scope of expansion, reusability and ease of adoption.

As a campaign to raise awareness and drive up developer adoption of AI and open source technologies, the hackathon was a great success. It helped shine light on the agility that open source technology enables for creative and innovative developers.

Open Source AI Hackathon Winners


“...each one of the contestants put in tremendous effort. And we saw the passion in every person, trying to do things not for winning, but about really building your projects. After a long time, I am attending such a hackathon where young folks are so passionate about building. Kudos to all of you”.
- Rukma Talwadker, Jury Member, Senior Principal Scientist at Games 24x7

“I really enjoyed judging all the projects - lot of interesting work. The Fifth Elephant has done a great job with mentoring and curating this hackathon”.
- Tanuja Ganu, Jury Member, Principal RSDE Manager, Microsoft India

“The hallmark of this hackathon was getting younger people to code for a longer period of time as opposed to a typical hackathon which turns out to be about — how do you build the coolest thing in the shortest period of time”.
- Sumod Mohan, mentor.

“What is impressive about this particular hackathon is, it is not just about cool ideas and fancy demos. It is actually about building a product or a software or a model that can live beyond the demo (and contest).”
- Soma Dhavala, team member at Project Seshu

“It was only through putting my ideas to code that I learnt what the specificity of implementing these (LLMs) were. I began my journey with a sense of hope and commitment towards FOSS principles, and the Hackathon only reinforced my belief that collaboration maketh a better product.”
- Sankalp Srivastava, Creator of Project Schematise

Problem Statement

The modern digital era has brought forth an abundance of information and content across various media formats, including audio and text. With this surge in content, there arises a need for tools that can assist in deconstructing, analyzing, and reconstructing this media to make it more accessible, understandable, and customizable for different audiences. The problem we aim to address with Decon is the challenge faced by users in managing and interacting with media content efficiently.

Specific challenges include:

  1. Difficulty in isolating specific elements of audio tracks, such as vocals or instruments, which can be essential for music producers, educators, or enthusiasts wanting to create karaoke tracks, remixes or to simply focus on a particular aspect of the music.
  2. The barrier language presents in understanding and enjoying content fully. This includes not just translating lyrics or dialogue but also transcribing audio into text for further analysis or accessibility purposes.
  3. Enhancing textual content through correction, translation, transliteration, explanation, summarization, or even generating new content based on existing patterns.
  4. The need for a unified platform that integrates various AI tools to address these challenges seamlessly without requiring users to navigate multiple applications or services.

Proposed Solution

To tackle the aforementioned challenges effectively, we propose the development of Decon - a multimedia workbook application designed as a one-stop solution integrating various AI-powered tools tailored specifically for audio and textual content manipulation.

Audio Features:

  • Stem Separation: Utilizing Spleeter’s capabilities to split audio files into individual stems (vocals, drums, bass etc.), enabling users to isolate specific elements of a track.
  • Voice to Text: Incorporating Whisper ASR technology for accurate speech recognition and transcription services. This feature allows users to convert spoken words into written text efficiently.
  • Pitch Adjustment: Offering functionality to adjust the pitch of audio files without significantly affecting their tempo or quality. This could be particularly useful for music practice or analysis.

Text Features:

  • Correction & Translation: Implementing advanced NLP models like GPT-4 for real-time correction of grammatical errors and translating text between multiple languages accurately.
  • Transliteration & Explanation: Facilitating easy conversion from one script to another while maintaining phonetic accuracy (transliteration) and providing explanations for complex terms or phrases when needed.
  • Summarization & Content Generation: Employing AI models capable of summarizing long pieces of text into concise versions without losing essential information and predicting next lines or generating new content based on prompts provided by the user.

Frontend & Backend Technologies:

  • Frontend Development: Leveraging Vue3 framework’s capabilities for building a user-friendly interface that is responsive and intuitive across devices.

  • Backend Services: Python will serve as the core programming language due to its extensive support for data manipulation and integration with AI models like Spleeter for stem separation and Whisper ASR for speech recognition.

Use Cases

Decon aims to cater to a wide range of users including but not limited to:

  • Music enthusiasts looking to create remixes or karaoke versions by isolating vocals/instruments from tracks.
  • Language learners wanting translations/transcriptions of songs or dialogues in foreign languages.
  • Content creators seeking tools for summarizing meetings/discussions quickly or generating lyrical ideas based on given prompts.
