# AI News, 2 October: Kling 4, Ideogram 4.5 and HeyGen Video

Three late-September creative AI updates now have different routes into a production workflow: Kling's limited Flash video preview, Ideogram's focused image edits, and HeyGen's API for short scenes with sound.

Published: 2026-10-02. Updated: 2026-10-02. Author: XANTRANS editorial.

Match the tool to the stage of work: Flash for a limited video sketch, Precise Edit for a controlled image revision, and HeyGen Video for an API-driven short scene with sound. Check access and review every result before production use.

## Kling 4: a storyboard plan ahead of the full model

Kling's full 4.0 model is designed around more than one prompt and one frame. Its announced controls include up to ten visual keyframes, a single generation of up to 30 seconds, and Omni Reference for combining image, video, subject and voice guidance. A product team might mark the opening packshot, a handoff and the final reveal as separate beats, then review whether the resulting object and timing stay consistent. These are announced capabilities, not measured results or a continuity guarantee.

What a limited group of Ultra Yearly subscribers can use now is Kling 4.0 Flash, available since September 28. Flash supports text-to-video, image-to-video and Omni Reference, but its 3–20 second clips are 720p, 8-bit SDR. The first-and-last-frame and multi-keyframe controls described for the full model are absent from Flash. Kling's wider 4.0 rollout is planned for October without a firm public date; 1080p and 4K HDR output and extension toward two minutes are labeled coming soon. Check actual account access before planning around full-model controls.

## Ideogram 4.5: edit one part of an approved image

Ideogram 4.5 arrived in late September and is available in its app and API. Its Precise Edit workflow starts from an existing image and an instruction, with an optional mask to isolate the area to change. In the API mask, black marks the edit and white marks what should be preserved. Up to four reference images can guide an unmasked request, or three alongside a mask. Ideogram says unchanged pixels are copied from the source and the returned image keeps its input dimensions. This makes a local revision possible from an approved image.

For example, a designer could approve a campaign layout, mask only the product, and request a color variant using a reference photo. The output would still need a close comparison around the product edge, brand mark and typography. The API accepts JPEG, PNG or WebP inputs up to 25 MB and aspect ratios from 1:6 to 6:1; large inputs may be scaled internally. Ideogram's showcase edits remain vendor demonstrations. API calls require a key; check account terms before a billable request.

## HeyGen Video: short scenes with sound through the API

HeyGen added its general-purpose Video model to the API in September. It is distinct from choosing an avatar to read a script: text-to-video can describe a scene, image-to-video can start from one image, and reference-to-video can use image, video or audio examples. The result is a five-to-fifteen-second clip with generated dialogue, ambience or effects, at a documented 480p or 768p. In reference mode, the combined limit is twelve items, with at most nine images, three videos and three audio files. Numbered references tie an input to a shot.

A licensed packshot could become the opening image for a short teaser with a single camera move and a stated sound cue. That is a proposed use, not a result we made. HeyGen's own model documentation flags long on-screen text, soft motion such as hair or paper, and close hand work as weaker areas. Start with a contained scene, then review the result. API access is live; HeyGen says web platform access is coming soon. Its API generation is billable, with rates depending on mode and resolution, so the exact request cost belongs in the team's preflight check.

## Practical takeaway

Use the available Flash preview to explore a simple motion idea without mistaking it for full Kling 4.0 controls. Use Precise Edit when the layout is approved and one image region needs revision. Use HeyGen Video when a short scene and sound must be generated through an API. Review rights, continuity, text and sound before production use.
