OpenRouter

OpenRouter is an interface that's supposed to offer a single way to interact with many large language models (LLMs). It's also a marketplace where you can find the best models and prices for your specific prompt. OpenRouter hopes to make it easier to pick and use LLMs, and to make it more economical.

Among OpenRouter's features:

• Trending Models: Perplexity's Llama3 Sonar, Soliloquy-L3 v2 and Command by Cohere are among the featured models, which are designed to offer better performance and lower costs.
• App Showcase: OpenRouter highlights a variety of apps built on top of LLMs, including websim, SillyTavern, Unhinged AI and others, to show what's possible with LLM integration.
• Model Browsing: You can filter models by modality (text-to-text, text-and-image-to-text), context length (4K, 64K, 1M) and price (free, $0.5, $10+).
• Prompt Pricing: Prices vary depending on the model and the number of uses, with some models available for free and others costing $0.5 to $10+.
• Series and Categories: Models are labeled by series (GPT, Claude, Gemini) and by function (roleplay, programming, marketing, etc.).
• API Integration: OpenRouter offers a simple API for using models in apps, with examples using the Fetch API and OpenAI's Client API.
• LLM Rankings: You can compare and rank models based on how they're used in different apps, which can help you find the best models for a particular job.

OpenRouter is geared for a broad range of customers, including developers who want to use LLMs in their apps and people who just want to use language models in the most efficient and economical way possible. By offering a single interface and marketplace for LLMs, OpenRouter hopes to make it easier to find and use the best models for your needs.
