About LLMWise
LLMWise is a multi-model LLM API that provides a consolidated means of accessing, comparing, blending, and routing a variety of AI models such as GPT-5.2, Claude, Gemini, DeepSeek, Llama, and Grok. This tool allows users to compare outputs from different models, blend the best components from these outputs, or allow AI system to judge which model's output wins, all within a single API call. It also features a smart routing functionality that selects the most appropriate model for each request. LLMWise integrates with a pay-as-you-go system, eliminating the need for subscriptions. Models can be hit simultaneously with the same prompt, and the responses stream back in real time, complete with metrics on latency, token counts and cost. LLMWise also supports a zero-retention mode, ensuring that user prompts and responses are never stored or utilized for training. Additionally, this tool is designed with a circuit-breaker failover across providers for production reliability. Lastly, LLMWise allows developers to implement a variety of orchestrated modes through a single POST request with real-time SSE streaming.
