OpenAI's budget GPT-4o mini model is now cheaper to fine-tune, too
Briefly

Prompt engineering is crucial for interacting with generative AI bots. OpenAI provides budget-friendly fine-tuning services for its GPT-40 mini AI model, disrupting existing costs.
Fine-tuning adjusts neural network parameters based on new training data, shifting the model's predictions towards the modified probability distribution desired by the user. OpenAI's GPT-40 mini fine-tuning starts at $3 per million tokens, significantly cheaper than previous versions.
