What is the best free AI API for developers?
The best free AI API for developers depends on the workload. Groq is best for speed and chatbot latency, Gemini is best for long-context tasks like RAG and document analysis, and DeepSeek is best for code generation and reasoning. For larger prototypes, developers can stack several free tiers and route each request to the provider that fits the task.
