In the v0.7 series, the Ultravox model is trained on GLM 4.6, taking the lead on audio reasoning tasks over closed source models like gpt4o-audio, while retaining advantages in speech understanding from previous versions. Ultravox is a multimodal model that can consume both speech and text as input (e.g., a text system prompt and voice user message). The input to the model is given as a text prompt with a special pseudo-token, and the model processor will replace this magic token with embeddings derived from the input audio. Using the merged embeddings as input, the model will then generate output text as usual.
Initial release of Ultravox.ai.
