Reviewer scorecard
“Best instruction-following of any model. Tool use and extended thinking are reliable. The API design is clean.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Claude consistently produces the most useful outputs for real work. The longer context window is a genuine advantage.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Anthropic's focus on safety without sacrificing capability is the right approach. Claude keeps getting better.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
