Speech-to-Speech Model
A single model that takes user audio directly as input and produces synthesized speech as output, without explicitly passing through the two separate stages of text transcription and large language model inference in between.

Reimer's measured answer is: speech-to-speech models are typically 3 to 5 times more expensive than parallelized pipelines, which is a deal-breaker for cost-sensitive scenarios like games.
Speech-to-speech models are less controllable than pipeline architectures on safety review, because LLM output can be intercepted and validated before being fed to TTS, whereas speech-to-speech models are hard to verify before output; voice style and intelligence level are also locked into the model's presets.
The only clear advantage of speech-to-speech models is understanding the user's tone (such as sarcasm), but Reimer believes this gap will narrow as STT capabilities evolve.
