Our own inference

Grom TV

The video model of the Grom line: up to 20 seconds of video with sound in a single generation. Your character speaks, moves and hits every syllable — on our hardware, not someone else's cloud.

Why

Video with sound, not a silent clip

Most video models hand you a silent clip: you glue the voiceover on afterwards and patch the lipsync with a separate service. Grom TV generates picture and sound in one pass — speech, ambience and music land in sync with the frame right away. The model takes text, a first-frame photo and an audio track as inputs — in any combination. Got a recorded voice? The scene will be acted out to it. Don't have one? Grom TV will voice it itself. The model runs on our own hardware: speed, queue and generation cost are controlled by us, not a third-party vendor. That's why we can put an SLA in writing for business — built for a content pipeline, not for luck.
Use cases

What Grom TV shoots

Every clip is a single generation: a prompt, a frame or a track goes in — a video with sound comes out.

Lipsync

One character in frame — our strong suit

Give the model a track and your character will live it out on screen: lips, expressions, breathing and gestures in time with the speech. Even a whisper — you can see the articulation shift and the smile land on the closing line.

It's important to know two things: how to create an avatar, and which AI brings it to life. Try Grom TV.

Inputs

Build the scene from what you have

Only the text is required. A photo sets the first frame, audio sets the track; whatever's missing, the model fills in itself.

A first-frame photo locks in the character and the style — handy for shooting a series of clips with the same hero. The audio can be speech, music or a mix: the model lays the track out across the scene's timeline itself.

Resolution

From draft to 4K

Run iterations at 480p — fast and cheap. Render the final at 1080p, and if the clip is headed for a big screen, Grom Pixel takes the frame up to 4K.

4K isn't a separate generation mode — it's Grom Pixel, our upscaling model, at work: it restores sharpness and texture instead of stretching pixels.

Comparison

Where Grom TV is strong — and where it honestly isn't

The model is tuned for clips with a character and sound: avatars, ads, social media. Complex physics and crowd scenes are better left to frontier models — they live in the same GPTunneL account.

SLA for businesswritten into the contract

Figures for third-party models are public vendor information as of July 2026; limits vary by plan and region. All four models are available in GPTunneL — compare them on your own task.

For business

A content pipeline on our hardware

Grom TV runs on our own machines, so volumes and deadlines are a matter of contract — not a queue in someone else's cloud.

Our own inference

Our own and leased GPUs: queue, priorities and generation cost are under our control.

SLA in the contract

Availability, generation speed and processing priority — fixed in writing.

Capacity for peaks

We reserve capacity ahead of campaigns and launches — your renders skip the shared queue.

The same key

Grom TV connects with the same GPTunneL API key — no separate integration.

Grom TV questions

Up to 20 seconds per generation — enough for a reel, a teaser or a scene with a line of dialogue. Longer stories are built from several scenes: a first-frame photo helps keep the character and style consistent between generations.
