Fireworks offers a range of GPU deployment options to support AI startups in scaling their operations, including serverless, on-demand, and enterprise solutions. On-demand GPUs provide a middle ground for companies needing reliable and fast processing without long-term commitments, offering significant cost and performance advantages over serverless and other platforms. Fireworks' on-demand service allows for automatic scaling, reducing idle costs, and offering flexibility in model choice and GPU configuration. The FireAttention stack enhances efficiency, providing substantial latency and throughput improvements. As companies grow, transitioning from serverless to on-demand becomes economically viable, with further potential to eventually adopt enterprise-level reserved GPUs for fully customized setups.
