As I covered in the AI agents book that I authored, I built a memory, autonomous collaboration, and control-generation system using Fireworks AI. After introducing Fireworks AI's high-speed inference engine, I found that communication speed between agents was about twice as fast as before. In particular, the function calling capability for agents to invoke external tools became very stable, and I verified that I could perfectly implement complex workflows that query and reflect enterprise data in real time. Because of this, I believe it became the most decisive differentiator that allowed me to apply AI automation in real enterprise environments. The LLM models currently coming out are hybrid models evolved from traditional foundation models, and while inference speed has become faster with Fireworks AI, response time has slowed due to the use of CoT and similar techniques. Because of that, to gain the benefits of that inference speed, I need perfect optimization of things in external function calling so that answers can be returned quickly. By optimizing that through Fireworks AI, I believe I was able to speed up the response time, which is a weakness of existing LLM models. Through this, customers or business users can quickly obtain answers in text form, which I see as a major advantage. The most satisfying characteristic of Fireworks AI was the combination of efficient inference speed and stable function calling. As I emphasized in my latest book on AI agents, the core of an autonomous agent system is the model's ability to interact with external tools in real time. I think Fireworks AI is innovative not only because it generates text quickly, but also because it reduces the latency that occurs when agents carry out complex tasks and, in the process, select and call tools.
