Question: Can you recommend a service that optimizes prompt routing to the best available endpoints for my AI application?

If you need a service that routes your prompts to the best available endpoints for your AI project, Unify is worth a look. It sends prompts to different providers, using a unified API to communicate with a variety of Large Language Models (LLMs). Unify has more advanced features, including customizable routing based on cost, latency and output speed, live benchmarking updated every 10 minutes, and the ability to set your own quality metrics and constraints. That makes it more adaptable and useful for a broader range of AI projects, with the potential to improve performance while cutting costs and speeding up results.

Another good option is PROMPTMETHEUS, an integrated platform to write, test, optimize and deploy one-shot prompts for more than 80 LLMs from top providers. It includes a prompt toolbox, performance testing and deployment to custom endpoints so you can easily integrate with third-party services. PROMPTMETHEUS offers several pricing levels, including a free tier, and lets you supply your own API keys, so it's adaptable and economical for different use cases.

If you want a broader toolset, check out Langtail. This service offers a no-code sandbox for writing and running prompts, adjustable parameters, test suites and detailed logging. Langtail is intended to make it easier to build and test AI apps, improve team collaboration and ensure your AI products work reliably. It has a free tier for small businesses and a Pro tier at $99/month, so it's useful for different use cases.
