Featherless

Featherless is a serverless API platform that provides instant access to over 30,000 open-source AI models through a single API key. It eliminates the need for hosting, scaling, or managing infrastructure, allowing developers and businesses to integrate state-of-the-art models for reasoning, coding, creative writing, and more. The platform supports models from Hugging Face and other sources, ranging from compact 0.5B parameter models to large 685B+ architectures like DeepSeek and Kimi-K2.

Key Features

• Single API access: Use any supported model without per-model API keys or setup.
• Extensive model library: Browse and test 30,000+ models across categories such as reasoning, creative writing, code generation, and multilingual chat.
• Flat-rate pricing: Predictable monthly plans with unlimited tokens, from $10/month (Basic) to $100/month (Full Context), each with defined model size and concurrency limits.
• High performance: Low-latency inference and reliable uptime designed for production workloads.
• Agent deployment: One-click launch of AI agents like OpenClaw for task automation.

Use Cases

• Rapid prototyping: Test and compare different models without upfront infrastructure.
• Production AI features: Integrate cutting-edge language models into applications via API.
