IDC's Analyst Brief highlights the importance of leveraging LLM software platforms to manage the complexities of generative AI (GenAI) deployments, providing insights into evaluating and selecting the right platform for organizational needs. Nearly half of surveyed decision-makers have engaged in over 25 GenAI proofs of concept, indicating both the urgency and complexity of integrating GenAI solutions. Organizations using LLM software platforms gain considerable advantages in deploying and managing GenAI solutions, including expanded use case reach, lifecycle management, data privacy and security, solution accuracy and coherence, complex workflow integration, and future-proofing. When selecting an LLM software platform, organizations should consider strategic and technological attributes such as broad ecosystem support, model orchestration, sandboxing capabilities, multi-persona tooling, end-to-end governance, and progressive development strategy. IDC's survey revealed that cost reporting and compliance auditing are among the top considerations when evaluating LLM software platforms, reflecting the need for transparency and adherence to regulatory standards. Ultimately, leveraging LLM software platforms is crucial for organizations to maximize their GenAI efforts, ensuring flexibility, scalability, and continuous improvement in deploying and managing GenAI solutions.
