Nvidia-backed Fireworks hits $17.5 billion valuation as companies pursue cheaper AI models

Fireworks, an Nvidia-backed startup that hosts AI models on cloud infrastructure (computing servers that developers can access over the internet), has reached a $17.5 billion valuation by helping companies use cheaper and more specialized AI alternatives instead of expensive models from major labs like OpenAI and Anthropic. The company is growing rapidly because finance executives are pushing their teams toward open-source models (freely available code that anyone can use and modify) to reduce costs, and Fireworks makes it easy for developers to customize these models with their own data for specific tasks.
