Released in 2026, it converts written text into natural-sounding spoken audio through xAI's audio API, accepting a text string, a voice identifier such as "eve", and a language parameter, and returning generated audio.
As xAI's first dedicated TTS model, there is no same-family predecessor to compare against; it instead expands xAI's modality coverage alongside its companion xAI Speech to Text v1 released around the same time, together forming a speech input/output pair that complements the text models in the Grok 4.3 line. These audio capabilities make it possible to build voice-driven pipelines around Grok.
Developers can call the model directly via xAI's API endpoint, and a voices listing endpoint is provided to enumerate the available voice identifiers and names. Direct access requires an xAI API key.
Because xAI has not published a detailed technical report or benchmark results for this model in the sources available here, specifics such as supported language count, sampling rate, or architecture are not documented publicly. This description is therefore limited to the verified API behavior detailed in xAI's own documentation.

"Best price" and the seller table are live Antseed catalog data (advertised $/1M tokens — or $ per generated image for unit-billed image models — not settled amounts). Reputation = buyer trust score (0-100, the Antseed SDK's own formula). "Routing" = the SDK's default buyer routing (what the VPR desktop app ships with): a trust ≥ 60 gate on the effective reputation, then cheapest-first among routable sellers; live failover state (per-peer cooldowns) is buyer-side runtime and not included. Model knowledge (TLDR, provider, About) via the VeniceStats enrichment layer. Advertised catalog, not the model used in any specific purchase. "Usage on Antseed" counts only settlements whose buyers share the per-model split on-chain (metadata v2/v3, opt-in), so every usage figure is a lower bound.
