Inworld TTS-1.5 Max is a text-to-speech model from Inworld AI, a startup known for conversational character and voice technology. Released in April 2026, it represents the top "Max" tier of Inworld's TTS-1.5 generation, positioned for users who prioritize the highest-quality, most expressive voice synthesis over lighter or faster alternatives.
As a dedicated speech model, its job is to turn written text into natural, lifelike spoken audio. That makes it well suited to applications like voice-over generation, interactive characters and agents, audio narration, and accessibility tooling where the realism and emotional nuance of the output matter. The "Max" designation signals an emphasis on fidelity, making it a strong default for production audio rather than throwaway prototyping.
If your project needs convincing, high-fidelity spoken output and you're willing to trade a little speed for richer, more human-sounding delivery, Inworld TTS-1.5 Max is built for exactly that use case.

"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.
