Will Hybrig run on your rig? 30-second answer.
Hybrig is local-first. That means it runs on your GPU — and your GPU has to be able to do the work. If your card isn’t big enough, Hybrig won’t run. We’re telling you up front instead of letting you install a 4GB app and find out at render time.
The short version
If you have a 3060 12GB or smaller, the full pipeline won’t run. Don’t download it. If you have a 3090, 4080, 4090, or 5090, you’re good for everything.
The floor — what you actually need
These are absolute floors, not suggestions. If you fall under them, the relevant feature won’t run — not "with a quality dip," not "slowly." It won’t run.
GPU
NVIDIA RTX 3090 / 4080 / 4090 / 5090
24GB VRAM minimum for the full pipeline (LoRA training, EchoMimicV2 lipsync, Flux + identity). 12–16GB cards run a partial pipeline (image gen + Wan 2.x video) but skip lipsync. AMD, Intel Arc, and pre-RTX cards are not supported.
System RAM
32GB minimum · 64GB if rendering while editing
ComfyUI keeps multiple model weights resident. Below 32GB the OS will start swapping mid-render and a 5-minute clip turns into a 45-minute one.
Disk
100GB free · SSD strongly preferred
Models alone eat ~60GB (Flux, Wan 2.2, Hunyuan, lipsync weights, LoRAs). Outputs are big mp4s and stack up fast. HDD works in a pinch but model load times double.
OS
Windows 11 · Linux · macOS Apple Silicon
Mac runs F5-TTS (voice) and the local LLM brain only. Video generation is Windows or Linux + NVIDIA today — the video-gen models don’t have working Metal builds yet.
Per-model breakdown — what each layer needs
Hybrig is a chain of models. Each one has its own floor. If you have a 12GB card, you can still run image gen and Wan 2.x video drafts — you just can’t train LoRAs locally and EchoMimicV2 won’t load. Here’s the full breakdown.
VRAM numbers are floors observed in production, not vendor specs. The chain auto-detects what your card can run and disables stages that won’t fit — loud about it, never silent.
You’re underpowered. Now what?
Three honest paths, in order of how much we’d actually recommend them:
Path 1 — Wait until you upgrade
GPU prices on the used market move fast. A used 3090 24GB lands around $600–$900 today. A new 4090 is $1,800–$2,400. If you’re going to ship spokesperson video monthly, the GPU pays for itself in 6–12 months versus a HeyGen Team seat. We’d rather you wait and run the real product than install Hybrig on a 3060 and have a bad time.
Path 2 — Read the upgrade guide
The /hardware page lays out which cards earn their keep on which jobs, the used market prices, and what you give up by going one tier down. Read that before you spend anything.
Path 3 — Cloud fallback (not yet shipping)
We’re building a pooled cloud-render option for users who can’t justify the GPU yet. It is not yet ready. When it ships, it will be billed per render, not per month, and it will be a clearly second-class path — the local pipeline is the product. We’ll update this section when it’s live.
Plain-words version
If you have a 3060, this won’t work. Don’t download it. If you have a 3070 or 3080 10GB, the lipsync stage won’t run — you’ll get image and basic video, no mouth-synced spokesperson clips. If you have a 3090, 4080, 4090, or 5090, you’re good for everything in the catalog.
We’re telling you this because frustrated users are worse than no users. The alternative is you install Hybrig, watch it fail at render time, and conclude the product is broken. It isn’t — your GPU just isn’t big enough for what you asked it to do. Better to know now.
Your rig clears the bar?
Then you’re good to go. Head back to the download page and install Hybrig.
