featherless.ai: Serverless AI Inference for Open Source Models

featherless.ai is a powerful, serverless AI inference platform that democratizes access to over 11,900 open source models, including cutting-edge variants like Llama 3, Mistral, Qwen, and Deep Seek. Designed for developers, researchers, and AI enthusiasts, it enables seamless integration with popular tools such as OpenHands, WyvernChat, and KoboldAI Lite through OpenAI-compatible API endpoints. With strong support for model compatibility, privacy-first architecture, and no chat history logging, featherless.ai ensures secure, anonymous, and high-performance inference. Its scalable plans offer predictable flat-rate pricing, eliminating pay-per-token fees, and allow users to run models up to 72B parameters with context lengths reaching 131,072 tokens. Whether for testing, fine-tuning, or production use, featherless.ai delivers fast, reliable performance with low TTFT and consistent throughput.

Key Features:

• Access to 11,900+ open source models including Llama 3, Mistral, Qwen, Gemma, and RWKV
• Serverless inference with advanced GPU orchestration and model loading
• Unlimited monthly tokens with flat, predictable subscription pricing
• OpenAI-compatible API endpoints for easy integration with tools like OpenHands, SillyTavern, and KoboldAI Lite
• Support for models up to 1,000B parameters and context lengths up to 131,072 tokens
• Private, secure, and anonymous usage with no chat history logged
