Altered
Proprietary voice morphing, expressive TTS, audio cleanup and realtime voice augmentation, plus explicitly managed customer-voice workflows. Third-party speech providers in Studio are not relabeled as Altered models.
Named morphing families and Fast variants, native TTS/cleanup, five realtime families and three managed voice-creation offerings. Exact private checkpoint inventory and several contract conflicts remain unresolved.
Start with the job your model needs to do. Then narrow by capabilities, provider and price.
Compare every model with the same request.
Estimate = (input tokens × input price + output tokens × output price) / 1,000,000. Include conversation history in input and billed reasoning in output. Input-only decision models ignore the output setting; enter all billed input for one decision, including its question and criteria. Media, tools and discounts are separate.
