Free mode with NVIDIA credits

Bring a free NVIDIA API key and VidFarm's AI reasoning — clip hunting, chat, and tool calls — runs on their credits. Render locally with the devcli and the whole loop costs $0. The one catch: nvidia can't generate images or video.

Adding a free NVIDIA key in Settings, AI-clipping a long video for free, editing a template by chat, and rendering locally at zero cost.

Key takeaways

  • Free mode = a BYOK NVIDIA key + local rendering. No VidFarm paid plan, no wallet.
  • The NVIDIA key is a lite, clipping-only key — pick the minimaxai/minimax-m3 model — that powers AI clip hunting, chat, and tool calls.
  • It cannot generate images or video — those requests hard-fail. Add a full key (OpenAI / Gemini / OpenRouter) for media.
  • Render locally for free with the devcli (in-process HyperFrames) — cloud renders always bill the wallet.
  • On the free tier you decompose reference videos yourself — there's no pre-computed grounding.

How free mode actually works

NVIDIA gives away free API credits on their build platform. VidFarm treats Nvidia (clipping only) as a real provider key, so you can point VidFarm's AI at those free credits: it'll hunt and cut clips, run the editor chat, and make tool calls — all on NVIDIA's dime. Pair that with the devcli's local rendering , which runs in-process on your machine for free, and the entire create-a-video loop costs $0 in VidFarm credits.

The trade-off is honest and worth stating up front: the NVIDIA key runs a smaller model (it's "less smart"), and — critically — it can't generate images or video. It's built for clipping and reasoning, not media synthesis.

Manual walkthroughSet up your free NVIDIA key

  1. Get a free NVIDIA API key

    Grab a key from NVIDIA's build / integrate platform, which comes with free API credits. That key is what powers VidFarm's clipping and chat for free. On NVIDIA's model catalog we specifically recommend minimaxai/minimax-m3 — it's the exact lite model VidFarm's clipping-only mode runs on, so it's the best-matched (and reliably free) choice.

  2. Add it in VidFarm

    Open Settings → Developer → Bring your own AI Keys → Add AI Key, choose Nvidia (clipping only) from the provider dropdown, and paste the key.

    Open Settings → Developer

  3. Use it for clipping and chat

    Now use NVIDIA for AI clip hunting and for the editor chat / tool calls. From the devcli you can select it explicitly on clip commands:

    Clip on the NVIDIA key
    vidfarm add-provider-key nvidia <secret>
vidfarm raws scan clip.mp4 --clip --provider nvidia

  4. Render locally for free

    Boot the editor with the devcli and render in-process — no wallet, no cloud. --no-cloud guarantees a fully offline, zero-charge run.

    Free local render
    vidfarm serve <template_id>     # then click "Render Local (Free)"
# or:
vidfarm render <forkId> --dir ./work --wait
The Settings → Developer 'Add AI Key' dialog with the provider dropdown open, highlighting 'Nvidia (clipping only)' among OpenAI, Gemini, OpenRouter, and ElevenLabs (audio only).
Add the NVIDIA key under Bring your own AI Keys — it's labeled 'Nvidia (clipping only)' because that's exactly what it does.

What nvidia can't doThe one hard limit

The NVIDIA key is deliberately scoped. It's in VidFarm's list of lite, text-only providers, so any image or video generation request fails fast with a clear error instead of silently doing nothing:

Heads up "Your Nvidia key is a lite, clipping-only AI key and can't generate images or video. Add a full AI key (OpenAI, Gemini, or OpenRouter) in Settings → AI keys to generate media." If you need generated media, add one of those full keys — nvidia handles the reasoning and clipping, the full key handles the pixels.
Terminal — the lite-key media guard
$ vidfarm images generate "a neon skyline"  # with only an NVIDIA key

Error: LITE_TEXT_ONLY_MEDIA_ERROR
The NVIDIA lite key (minimax-m3) can hunt clips, chat, and call tools,
but it can NOT generate images or video. Add an OpenAI/Gemini/OpenRouter
key in Settings → Developer to unlock media generation.
What it costs Free mode's real saver is local, in-process rendering — it never touches your wallet. A cloud render always bills at 1.2× real compute (see the wallet chapter ). Use --no-cloud to guarantee $0.
Note One free-tier honesty note: paid accounts get a pre-decomposed viral library and proven prompt-harness. On the free tier there's no pre-computed grounding — you and your agent decompose the reference video yourselves (the skill coaches the 3-paintbrush method). More in The three paintbrushes .

Where to go next

Make a video for $0

A free NVIDIA key does the clipping and reasoning; the devcli renders locally in-process. The whole loop costs nothing — just add a full AI key when you want generated media.
