Quick Setup (< 1 hour)

You can use Fireworks AI to access and run open-source large language models and image models through a fast inference API. It lets you fine-tune models on your own data, deploy them to production, and run reinforcement learning training workloads. You can choose serverless pay-per-token pricing, dedicated on-demand deployments, or reserved capacity. It supports OpenAI and Anthropic-compatible APIs, making it easy to switch from existing setups without rewriting code.
