Prefer an active alternative unless you maintain a private fork or need a frozen dependency. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## Common questions ### What is the difference between ColossalAI and codellama? ColossalAI: Making large AI models cheaper, faster and more accessible. codellama: Inference code for CodeLlama models.
