ComfyUI v0.43.0, released on October 27, 2026, adds Kling 4.0, FLUX 3 Max video, PixVerse V6 Max, Mirelo sound effects, HeyGen voice cloning and a Clarity video upscaler as Partner Nodes. Partner Nodes run on the provider's servers and bill your Comfy credits, so one graph can now take a still image to a narrated, scored, upscaled clip. We read the price badge on every new node. The same 10-second 720p clip costs $0.58 in PixVerse V6, $0.61 in FLUX 3 Max and $2.25 in Kling 4.0. The cheap FLUX price is a launch rate that ends on November 7.
Two more numbers from the release. PixVerse V6 is now 66% cheaper in ComfyUI than it was in v0.42. And the 1.43x factor we found in ComfyUI v0.38 carries over: Kling 4.0 costs $0.157 a second on fal's Kling 4.0 page and $0.2245 inside ComfyUI.
What ComfyUI v0.43 adds for creators
The release has 16 Partner Node changes. These are the ones that make or finish media, with the price the node shows.
| New node | What it does | Price in the node |
|---|---|---|
| Kling 4.0 (text, image, reference, edit) | 3 to 30 second clips with sound, up to 10 keyframes | $0.2245/s at 720p, $0.336/s at 1080p |
| FLUX 3 Max video | 5 to 20 second clips with sound, from text or images | $0.0608/s at 720p until Nov 7, then $0.2431/s |
| PixVerse V6 Max | 1 to 15 second clips, higher fidelity tier of V6 | $0.0763/s at 720p with sound until Nov 3, then $0.0953/s |
| Mirelo Video to SFX | Sound effects synced to a video you connect | $0.0133/s |
| HeyGen Voice 1.0 Instant Clone and Text to Speech | Clone a voice, then read a script in it | Clone free; Turbo speech $0.0057 per 1,000 characters until Oct 31 |
| Clarity AI Crystal Video Upscale | Upscales a clip to 1080p up to 4K | About $0.30 to $1.29 per second of output |
| VEED Fabric 1.0, Lipsync 2.0, Clean Audio | Talking photo, mouth re-sync, speech cleanup | $0.2145/s at 720p, $0.10/s, $0.018/min |
| Ideogram Vector | Text or image to editable SVG | $0.19 to $0.46 per SVG |
| Meshy Smart Topology | Text or image to a 3D model with clean topology | $0.286 untextured, $0.858 with a 2K or 4K texture |
| Krea 3 ultra mode | Several edit candidates, returns the best one at 2K | $0.3718 per image |
Two free local nodes come with it. Branch lets you wire several inputs into one node and pick which path runs by name, which is how you swap video models in one graph without rewiring. Pad Image adds mirror padding, which avoids the hard edges a solid-colour border leaves when a model needs dimensions in multiples of 32. Bria's FIBO 2.0 generate and edit nodes, MOSS-Image edit LoRAs and an ACEScg option for EXR saves round out the release.
One 10-second clip, four video nodes
Every video node in the release bills by the second, so the clip length you pick is the price you pay. We worked out a 10-second shot at both resolutions from the badge formulas in the node source. All four generate a soundtrack; the PixVerse figures below are with sound switched on.
| Node | 10 s at 720p | 10 s at 1080p | Longest clip | Price after the launch rate |
|---|---|---|---|---|
| PixVerse V6 | $0.58 | $1.12 | 15 s | No launch rate |
| FLUX 3 Max | $0.61 | $1.04 | 20 s | $2.43 and $4.15 from Nov 7 |
| PixVerse V6 Max | $0.76 | $1.46 | 15 s | $0.95 and $1.78 from Nov 3 |
| Kling 4.0 | $2.25 | $3.36 | 30 s | No launch rate |
Kling 4.0 costs roughly four times as much per second as the others, and it buys length and control. It is the only one of the four that runs to 30 seconds in one call. Its image node takes up to 10 keyframes (a first frame, a last frame and frames in between), and you can name them in the prompt as @Image1, @Image2 and so on. A 30-second 720p Kling shot is $6.74, the price of more than 11 ten-second PixVerse V6 clips.
PixVerse V6 is the price surprise. In v0.42 the same 10 seconds at 720p with sound cost $1.72. The PixVerse V6 Max pull request cut every V6 rate by the same 66%, and Comfy's Partner Node pricing page lists the new rates. The PixVerse V6 guide explains the trade between the two tiers: V6 Max drops the style presets and the multi-shot option in image to video, and Fusion (reference to video) stays on V6 only.
The launch prices end on three different dates
Three of the new nodes carry a launch price with a cut-off written into the badge, so the price you see today changes on its own.
- HeyGen Voice, October 31. Turbo speech goes from $0.0057 to $0.0107 per 1,000 characters, and the full model from $0.0215 to $0.0429.
- PixVerse V6 Max, November 3. A 10-second 720p clip with sound goes from $0.76 to $0.95, about 25% more.
- FLUX 3 Max, November 7. The 75% launch discount ends and a 10-second 720p clip goes from $0.61 to $2.43. This one comes from Black Forest Labs and fal: fal's FLUX 3 Max page runs the same discount from October 15 to November 7.
The practical reading: if you were going to test FLUX 3 Max inside ComfyUI, do it before November 7, and judge it against Kling and PixVerse at the price it will have afterwards, not the launch price. After November 7, FLUX 3 Max at 720p costs more per second than Kling 4.0 at 720p ($0.2431 against $0.2245).
Sound, voice and upscaling: the rest of the clip
A finished short needs more than the generated shot. The release adds a node for each of the remaining jobs.
Sound effects. Mirelo Video to SFX watches the clip you connect and generates effects that match the action, with an optional prompt and a list of sounds to avoid. It accepts videos up to 600 seconds and costs $0.0133 a second, so $0.13 for 10 seconds. That is close to the $0.01 a second fal lists for Mirelo SFX 1.6; the ComfyUI node runs the newer SFX 2.0.
Narration in your own voice. The HeyGen Instant Clone node is free and returns a voice ID; the Text to Speech node reads your script in that voice. Plug that speech into Mirelo's optional audio input, leave preserve_speech on, and Mirelo mixes your narration under the effects in one track. A 150-word narration is about 900 characters, roughly half a cent on Turbo before October 31 and one cent after. HeyGen's own platform is cheaper still: as we reported in our HeyGen Voice Turbo cost breakdown, Turbo is free there until November 30 and $4 per million characters afterwards, against $10.73 per million in the node from November 1.
Upscaling. Crystal Video Upscale bills by the megapixel-second of output. A 1080p result costs about $0.30 a second, so $2.97 for 10 seconds, and clips above 30 fps cost double. That is more than rendering at 1080p in the first place in PixVerse V6 ($1.12) or FLUX 3 Max at launch price ($1.04). Use the upscaler on footage you already have, such as an older 720p render or a phone clip, not as a step after a model that can render 1080p itself.
Talking photos and dubbing. VEED Fabric 1.0 turns a still image plus a speech track into a lip-synced talking video at $0.2145 a second at 720p. Lipsync 2.0 re-syncs a speaker's mouth to new audio at $0.10 a second, and Clean Audio removes background noise for $0.018 a minute.
The 1.43x pattern holds in v0.43
We compared each new badge with the provider's own list price. Where both prices are published, the ComfyUI badge is 1.43 times the list price, the same factor we found on Recraft, Claude and GPT nodes in v0.38.
| Job | Provider list price | ComfyUI v0.43 badge | Ratio |
|---|---|---|---|
| Kling 4.0, 10 s at 720p | $1.57 (fal) | $2.25 | 1.43x |
| Kling 4.0, 10 s at 1080p | $2.35 (fal) | $3.36 | 1.43x |
| FLUX 3 Max, 10 s at 720p, launch rate | $0.43 (fal) | $0.61 | 1.43x |
| FLUX 3 Max, 10 s at 720p, from Nov 7 | $1.70 (fal) | $2.43 | 1.43x |
| Ideogram Vector, one Low SVG | $0.13 (Ideogram) | $0.19 | 1.43x |
| HeyGen Voice Turbo, 1M characters, from Nov 1 | $4 (HeyGen) | $10.73 | 2.68x |
Comfy does not publish a margin, and the badges show the cost before you queue, so nothing is hidden. The gap only shows up when you put the two price lists side by side. The HeyGen row is the outlier at 2.68x. The Ideogram row matches the API prices in our Ideogram Vector comparison.
Kling 4.0 is the costliest example. Ten 10-second 720p shots cost $22.45 in ComfyUI and $15.70 on fal, a $6.75 difference for one evening of iteration. In exchange you get a single credit balance, no separate accounts and every model in one canvas, where you can pass a Kling shot straight into Mirelo and the upscaler.
How to build the clip in ComfyUI
None of this needs a terminal. The ComfyUI Desktop app is a free download, and Comfy Cloud runs the same canvas in a browser.
- Update or install. Open ComfyUI Desktop and accept the update to v0.43, or start a Comfy Cloud session.
- Sign in and add credits. Partner Nodes need a Comfy account with a credit balance. Each node shows its price in its header before you run it.
- Make the still. Use any image node you already like, or Krea 3 at $0.0858 for a 2K image in fast mode.
- Animate it. Double-click the canvas, search "Kling 4.0 Image to Video" or "PixVerse", connect your image, set 10 seconds and 720p. Add a Branch node in front of two video nodes if you want to switch models without rewiring.
- Add voice and sound. Run "HeyGen Voice 1.0 Instant Clone" once on a clean recording of your voice, then feed its voice ID and your script to the Text to Speech node. Connect the clip to "Mirelo Video to SFX" and the speech to Mirelo's audio input, with preserve_speech on.
- Finish. Join the clip and Mirelo's audio output in a Create Video node and save it. Skip the upscaler if you rendered at 1080p.
Our 10-second example, PixVerse V6 at 720p with sound, plus Mirelo effects, plus a 150-word HeyGen Turbo narration, comes to about $0.72 before October 31. The same chain on Kling 4.0 is about $2.38.
Which node to pick
For drafts and social clips, start with PixVerse V6. At $0.58 for 10 seconds with sound it is the cheapest video node in the release, and it is now a third of its v0.42 price. Step up to V6 Max when you need better prompt following and texture, and test it before November 3.
Try FLUX 3 Max this week while it costs $0.61 a clip, but keep it in your workflow after November 7 only if it clearly beats the others, because it will then cost more than Kling at 720p. Use Kling 4.0 for the shots that matter: long takes, keyframed moves between specific frames, and edits to existing footage.
If you already pay Kling, fal or HeyGen directly and render a lot, their own sites are about 30% cheaper, and HeyGen's Turbo price is 37% of the node's. If you render a few dozen clips a month, the convenience of one canvas and one balance is worth the difference.
Frequently asked questions
What is new in ComfyUI v0.43.0?
Partner Nodes for Kling 4.0, FLUX 3 Max video, PixVerse V6 Max, Mirelo sound effects, HeyGen voice cloning and speech, Clarity Crystal video upscaling, VEED Fabric, Lipsync and Clean Audio, Ideogram Vector, Meshy Smart Topology, Bria FIBO 2.0 and a Krea 3 ultra mode. Locally, it adds a Branch node, a Pad Image node with mirror padding and MOSS-Image edit support.
How much does a 10-second Kling 4.0 clip cost in ComfyUI?
$2.25 at 720p and $3.36 at 1080p. The same clip costs $1.57 and $2.35 through fal's list price.
Why did PixVerse V6 get cheaper in ComfyUI?
The pull request that added PixVerse V6 Max also repriced V6 and updated Comfy's billing rate cards. Every V6 rate fell by the same 66%, so a 10-second 720p clip with sound went from $1.72 to $0.58. Comfy's notes do not give a reason.
When does the FLUX 3 Max discount end?
November 7, 2026. After that, the ComfyUI node costs $0.2431 a second at 720p and $0.4147 at 1080p, which is $2.43 and $4.15 for a 10-second clip.
Do I need to install anything from the command line to use these nodes?
No. Partner Nodes run on the provider's servers. You need ComfyUI Desktop or Comfy Cloud and a Comfy account with credits; your graphics card does not matter for them.
Is the HeyGen voice in ComfyUI the same price as on HeyGen?
No. In ComfyUI, Turbo speech costs $10.73 per million characters from November 1. HeyGen lists $4 per million and makes Turbo free on its own platform until November 30. For a single narration the difference is under a cent.
