Build voice & avatar systems

Speak — Inworld Realtime TTS-2; Present — HeyGen Avatar V; Animate — OmniHuman-1.5; Sync — KlingAI Lip-Sync; Finish — lipsync-2-pro. Each row above expands with the model's live pricing, capability chips, and sample outputs.

HeyGen Avatar V runs $0.1 per second while OmniHuman-1.5 works out to roughly $0.13 per second ($1.3247 per 10 seconds) for higher-fidelity, single-image-driven video. The cost gap is modest — the real difference is input and fidelity: realtime assistants tolerate less fidelity than hero marketing content.

KlingAI Lip-Sync charges $0.0462 up to 5 seconds and $0.0924 up to 10, then $0.0092 per extra second; sync lipsync-2-pro is a flat $0.0733 per second at up to 4K. Short clips favour the banded model, long 4K post favours flat per-second pricing only when the detail is visible.

Every price on this page is the model's published rate from the live Runware catalog, using the cheapest listed configuration unless stated otherwise. Prices vary with resolution, duration, quality tier, or token volume, so check the pricing table on each model page before estimating unit economics.

The Runware catalog does not publish per-model latency figures, so this page does not quote end-to-end timings. Where a model's own description commits to speed (for example sub-second generation or realtime streaming), that claim is repeated here. For anything else, benchmark the exact models in the Playground with your own payload sizes before committing to an SLA.

Models are addressed by versioned AIR identifiers, so a workflow pinned to specific model versions keeps producing the same behaviour as new versions ship. Adopt upgrades deliberately by re-running your evaluation set against the new version before switching production traffic.

A blueprint bundles the small set of models you would actually wire together for one production use case, instead of ranking a whole category. Each pick covers one stage of the workflow and links to its model page for full schema, pricing, and examples.

Picks are live models from the Best Text-to-Speech (23 live models), Best AI Avatar Generators (10), and Best Lip Sync (22) collections, covering the speech, avatar video, and lip-sync stages at two fidelity tiers each where the catalog supports it.
