Everything We Shipped in May 2025

In May, significant advancements were made with the introduction of Workflows, a highly requested feature that enables users to design complex conversation flows visually using a node-based interface, eliminating the need for single-prompt limitations. This enhancement includes features like conditional logic, sentiment routing, and multi-assistant orchestration, making it suitable for applications such as call centers and patient onboarding. Additionally, the platform saw the release of new AI models and voice options, including models from Azure OpenAI and Anthropic, and new voices like Kylie and Sesame. Developer tools and API enhancements were also introduced, offering more granular control over server messages, endpointing, chat management, and session persistence. The platform integrated with GoHighLevel for contact management and calendar scheduling, supported regional model specifications for data compliance, and improved cost tracking. Two community programs were launched: the Vapi Build Challenge, which concluded with innovative community submissions, and the Vapi Creators Program, offering early access and support to builders and educators. Platform improvements included workflow entry points, warm transfer mode, enhanced cost tracking, and extended server timeouts, inviting feedback for future developments.
