[AI Infrastructure Startup Trajectory Secures $40 Million in Funding, Sequoia Capital Participates] BlockBeats News, August 11: According to a report by The Information, AI infrastructure startup Trajectory announced it has secured $40 million in funding, bringing its post-money valuation to $300 million. The round was participated in by Sequoia Capital, though the specific funding round and other investors have not yet been disclosed. Trajectory was founded by researchers from tech companies such as Google and Apple and primarily helps enterprises customize open-source AI models to meet specific business needs, as well as optimize the software toolchain that supports AI Agent operations (referred to as "Agent Harness"). As the cost of using closed-source large models continues to rise, more and more companies are seeking alternatives: on one hand, reducing costs by fine-tuning and customizing open-source models, and on the other, improving Agent execution frameworks to enable AI models to more effectively call tools and perform tasks. This trend is driving a new wave of entrepreneurship focused on model adaptation and Agent infrastructure. Trajectory aims to address key challenges enterprises face in deploying AI Agents, including model performance optimization, task execution reliability, and adaptation to enterprise-specific scenarios. The company hopes to help businesses build more efficient and cost-effective AI applications by providing model customization and Agent operational infrastructure. [Original Link]
