Praktika and OpenAI Cookbook serve completely different needs: one is a mobile language app for speaking practice, the other is a free code repository for developers using the OpenAI API. Choose Praktika if you're an intermediate learner aiming to improve fluency through conversation; pick the Cookbook if you're a Python developer who needs ready-to-use examples for text generation, embeddings, or fine-tuning. Neither directly competes, so your choice depends on whether you want to learn a language or build with AI.
