Enterprise adoption of large language models (LLMs) is rapidly increasing, with predictions that over 80% of enterprises will use generative AI applications by 2026, up from 5% in 2023. This surge highlights LLMs as crucial tools for business development and productivity, prompting organizations to make strategic decisions about which models to adopt, considering factors like data security and the benefits of open-source versus proprietary models. A survey of 550 Kong users, developers, and IT leaders revealed that spending on LLMs is expected to grow, with current investments exceeding $250,000 annually for some. Despite concerns over security and compliance, newer entrants like DeepSeek have gained traction, with significant usage noted among engineers and tech leaders. Google models also saw a substantial rise in adoption in early 2025, overtaking other competitors due to strategic integrations and aggressive pricing. Overall, 82% of respondents feel that generative AI will positively impact their careers and organizational innovation, although a small minority remain skeptical about its benefits.
