Pre-trained AI models underperform on African content: Whisper's word error rate on Yoruba is 5x higher than English; GPT-4 scores 30% lower on African language benchmarks. Fine-tuning closes this gap by adapting pre-trained models to your data. With LoRA, you can fine-tune with only 0.4% of parameters, making it feasible on free Google Colab GPUs.
Learn fine-tuning for africa step by step with narration, interactive theory, and hands-on pipeline activities. Everything you need is inside the lesson — no coding required.

Learning Objectives
What you'll learn in this module
- Understand why pre-trained models underperform on African data (the adaptation gap)
- Prepare training datasets in HuggingFace format for fine-tuning
- Demonstrate transfer learning: pre-train on general data, fine-tune on African data
- Use the LoRA/PEFT pattern to fine-tune translation and speech models efficiently
Sector Applications
How this technology is used across African sectors
Fine-tune an image classifier on local crop diseases — PlantVillage's models started as generic classifiers adapted to African crops
Adapt Whisper for clinical speech in local languages so doctors can dictate notes in Twi, Yoruba, or Amharic
Fine-tune a reading assessment model for African languages — what Nyansapo Labs does for literacy in Ghana
Adapt object detection models to recognize local wildlife species not in standard training data
