Quick pick: nothing on the market is truly limitless, but a handful of tools get close enough to matter for a high-volume faceless channel. HeyGen's Creator plan is the strongest pick for uncapped standard-quality avatar videos, and Faceless.so is the closest thing to a genuinely flat-rate, fully automated pipeline if you're willing to trade creative control for volume.

"No credit limits" gets searched a lot because credit systems are genuinely confusing — a plan can advertise "unlimited" while quietly capping the specific feature you actually need. We went through the current field to separate what's really flat-rate from what's unlimited in name only, so you're not caught off guard mid-month. If your budget is zero rather than just capped, our best free AI video generators for YouTube Shorts roundup covers the tools with a genuinely usable no-cost tier instead.

Why "unlimited" AI video is rare

Every AI-generated clip runs on GPU compute that costs the provider real money per second, whether that's a five-second B-roll clip or a full avatar video. That's the economic reality behind every "unlimited" claim in this category: a vendor can make one specific layer of the product flat-rate — exports, a lower-resolution tier, a "relaxed" generation queue that runs slower during off-peak hours — while still metering the expensive part with credits. The honest version of "no credit limits" is usually "no limit on the thing that's cheap for us to give you unlimited," not zero limits anywhere in the product.

That's worth knowing going in, because it changes what question to ask about each tool: not "is this unlimited," but "unlimited at what, and where's the real ceiling."

Comparison table

Every one of these terms — and which plan they apply to — shifts as these companies restructure pricing. Confirm the current plan details before assuming last month's terms still hold.

1. HeyGen — best for uncapped standard-quality avatar videos

HeyGen's Creator plan advertises unlimited videos, and for its standard Avatar III output, that holds up in practice — you can generate as many of those as you want without watching a credit meter. The catch is Avatar IV, HeyGen's higher-fidelity avatar mode: it draws from a separate Premium Credits pool that Creator's monthly allowance only covers for a limited number of minutes before you need more credits. For a faceless channel using a standard talking-avatar format at volume, that's still the closest thing to genuinely unlimited generation on this list.

Pros: Truly uncapped standard avatar videos on Creator, unlimited photo avatars, voice cloning included. Cons: "Unlimited" doesn't extend to the higher-fidelity Avatar IV mode, which still runs on a capped credit pool.

2. InVideo AI — best for unlimited exports, not unlimited generation

InVideo AI's paid plans all include unlimited, watermark-free exports — genuinely no cap there, and exporting itself doesn't consume credits. Where the limit actually lives is the AI generation step before export: every paid tier comes with a fixed monthly credit allowance for AI-assisted drafting, scene generation, and the assistant features. If your workflow is mostly editing and exporting rather than generating new AI footage from scratch every time, InVideo's real-world limits matter less than the "unlimited exports" headline suggests either way.

Pros: Genuinely unlimited exports on every paid plan, real timeline editor, no watermark on paid tiers. Cons: AI generation itself is still credit-metered, so "unlimited" only covers part of the workflow.

3. Faceless.so — best for fully automated, flat-rate volume

Faceless.so is built around a different promise than the tools above: unlimited generation of its specific short-form video formats, with research, scripting, voicing, and posting handled automatically. That flat-rate volume comes at the cost of creative control — you're working inside its templates and automated pipeline rather than directing individual shots the way you would with a generator like Kling or Runway. For a volume-first channel that's comfortable trading creative input for a hands-off, uncapped pipeline, it's the tool built specifically for that trade.

Pros: Genuinely unlimited output for its supported formats, handles scripting and posting automatically, no per-clip credit anxiety. Cons: Locked into its own templates and style, less creative control than a standalone generator.

4. Luma Dream Machine — best "relaxed" unlimited tier

Luma's Unlimited plan, priced around $95/mo, works differently from a flat cap: you get an initial allowance of fast-priority credits, and once those are spent, generations continue on a slower "relaxed" queue without a hard stop. That's a real form of unlimited — you won't hit a wall mid-month — but it isn't unlimited at full speed, and the price puts it well above the other options here. It fits a channel generating heavy volume that can tolerate slower turnaround once the fast allowance runs out.

Pros: No hard generation cap once fast credits are used, strong image-to-video fidelity, solid camera-control tools. Cons: Highest price on this list, "unlimited" generations run on a slower relaxed queue.

5. Runway — a cautionary tale, not a current pick

Runway used to sell a genuine Unlimited plan. It doesn't anymore: Runway stopped offering Unlimited to new subscribers on June 1, 2026, and migrated remaining subscribers onto a credit-based Max plan by September 1, 2026. Max carries a much larger monthly credit allowance than Runway's standard tiers, which softens the change for heavy users, but it's still a metered system with a real ceiling. Runway is worth including here specifically as a reminder: an "unlimited" label today isn't a permanent feature of a product, and a workflow built entirely around one vendor's current pricing is worth hedging against.

Pros: Still among the best output quality in the category, Max's credit pool is generous relative to standard tiers. Cons: No longer genuinely unlimited at any price, the change happened with real migration deadlines for existing users.

How to choose

Start with which part of your workflow actually needs to be uncapped. If your format is a standard talking-avatar video and you're publishing a high volume of them, HeyGen's Creator plan removes the credit anxiety for exactly that use case. If you're editing more than you're generating from scratch, InVideo's unlimited exports matter more than its credit-gated AI features. If you want the entire pipeline — script, voice, visuals, posting — handled without touching a credit balance at all, Faceless.so is built for that trade-off specifically. And if you're generating original B-roll or cinematic shots where creative control matters more than volume, none of the "unlimited" tools here are really the right fit — see our best AI video generators roundup, or our Kling vs. Runway comparison for the credit-based tools that actually lead on quality.

Whatever you land on, verify the current terms before building a production schedule around them — Runway's own Unlimited-to-Max transition in 2026 is proof that "unlimited" pricing changes, sometimes with only months of notice.

Bottom line

No AI video tool offers genuinely infinite generation — the economics don't support it. What exists instead is a short list of tools that make the specific thing you need uncapped: HeyGen for standard avatar volume, InVideo for exports, Faceless.so for a fully automated pipeline, and Luma for a slower-but-uncapped relaxed queue at a higher price. Match the tool to the part of your workflow that actually needs to scale without a credit ceiling, and confirm the current plan details before you commit a production schedule to any one of them.
