The world of sales is evolving rapidly, driven by technology that's impacting how sales people connect with and engage with customers. Generative AI has the potential to revolutionize sales teams by harnessing large language models (LLMs) to generate personalized content, build coaching plans, and create comprehensive onboarding and training programs. This technology can streamline the sales cycle, save time, reduce resource-intensive tasks, and focus on building closer relationships with clients and prospects. Organizations must consider factors such as cost, time to market, customization, control, scalability, integration, support, and maintenance when deciding whether to use an existing LLM or build their own custom model.
