LM Studio

Backyard AI is a privacy-focused platform that enables users to create and interact with AI-powered characters through text and voice chats. It offers a desktop application that runs locally on your computer, ensuring that all data remains private and is not transmitted to external servers. It supports a wide range of large language models, allowing for immersive role-playing experiences without filters or censorship. Users can browse and engage with thousands of AI characters via the Character Hub, and the platform also offers mobile tethering, enabling access to local AI models from mobile devices. Backyard AI provides both free and paid cloud plans, with the free tier offering access to smaller models and the paid options unlocking larger models with extended context windows. It is designed to be beginner-friendly, requiring no technical knowledge to get started.

OpenRouter is a unified interface for LLMs. OpenRouter scouts for the lowest prices and best latencies/throughputs across dozens of providers, and lets you choose how to prioritize them. No need to change your code when switching between models or providers. You can even let users choose and pay for their own. Evals are flawed; instead, compare models by how often they're used for different purposes. Chat with multiple at once in the chatroom. Model usage can be paid by users, developers, or both, and may shift in availability. You can also fetch models, prices, and limits via API. OpenRouter routes requests to the best available providers for your model, given your preferences. By default, requests are load-balanced across the top providers to maximize uptime, but you can customize how this works using the provider object in the request body. Prioritize providers that have not seen significant outages in the last 10 seconds.
