I wanted my AI Year-End Wrap-Up just like @Spotify Wrapped, @YouTube Recap, or @LinkedIn Year in Review, but it didn’t exist. Since @OpenAI @ChatGPTapp (@Google, @AnthropicAI, etc) didn’t offer this, I decided to build one for myself and for everyone: niamindai.com/

Additionally, I fine-tuned a @OpenAI Whisper Tiny model on this dataset! This is a big step because Igbo—one of the included languages—was not originally supported by Whisper. Explore the dataset: huggingface.co/datasets/benj… and model: huggingface.co/benjaminogbon…

We’re on a journey to advance and democratize artificial intelligence through open source and open science.
