I think OP means that FOSS didn't digest many multimodals of phi4-mini-multimodal such as Audio Input (STT) and Audio Output (TTS), also Image Input also not much supported in many FOSS.
AFAIK, Phi-4-multimodal doesn't support TTS, but I understand OP's point.
The recent Qwen's release is an excellent example of model providers collaborating with the local community (which include inference engine developers and model quantizers?). It would be nice if this collaboration extended to wrapper developers as well, so that end-users can enjoy a great UX from day one of any model release.
