What we know about OuteTTS

OuteTTS is a text-to-speech apis platform: the llama.cpp-native option: runs via GGUF on CUDA/ROCm/Vulkan/Metal and even in the browser (Transformers.js). License splits by model: the 0.6B (Qwen3-based) is Apache-2.0, the 1B Llama-based flagship is CC-BY-NC-SA-4.0 (non-commercial). This profile tracks what we have verified about OuteTTS, each fact linked to a primary source and dated.

OuteTTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current OuteTTS quote, it is the fastest way for us to close that gap.

On capabilities, OuteTTS covers instant voice cloning and self-host / on-prem option. Each of those is verified against OuteTTS's own docs or dashboard, not marketing copy.

In total we track 9 verified facts for OuteTTS today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the OuteTTS fact sheet below, and each row links the primary source it came from so you can check our work.

Whether OuteTTS is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how OuteTTS actually fares against the platforms buyers most often weigh it against.
