Meta's Llama API, Anthropic, and OpenRouter showed the highest availability at over 99.98%, with Google Gemini and OpenAI slightly behind. The study highlighted that the worst-performing region, often Tokyo or São Paulo, revealed more significant differences than average uptimes. Several smaller providers experienced a higher number of attributed outages, while the top-tier APIs maintained consistent availability. AI
