edit(content): review batch-1 editorial pass across 24 posts (EN + ZH)

- voice: first-person throughout (we/our -> I/my), matching the post guideline
- privacy: internal LAN IPs replaced with placeholder hostnames
  (n8n.internal, gpu-node.internal); one compose volume path generalised
- ZH twins: Traditional -> Simplified characters (site serves zh-Hans),
  whole-file renormalisation where the twin was still Traditional
- dynamicCta: true on 12 posts so the contextual dual-track CTA renders
- long configs wrapped in <details class="tech-deep-dive"> with a summary
  naming the artefact and line count
- self-hosted-tts: token refresh now writes .tmp + atomic mv, with a note on
  the 401 race the old truncating redirect created

Which AI video generator should you actually use in 2026 — and how much of it can you really get for free?
AI video has changed faster than almost any other creative tool I've used. A year ago, decent video generation meant a paid subscription and hoping for the best. Today you can generate synchronized video *and* audio with an open-weight model on your own GPU, or get genuinely useful free credits from half a dozen platforms.
But there's a catch hiding in the word "free". It means at least four different things in this market, and most articles don't tell you which one they're talking about. This guide compares the options that are actually usable in 2026, separates marketing from reality, and ends with a hands-on test: I generated a short video with the open-weight model **LTX-2.3** through PinkCherry, and I'll show you the result.

1. **Free daily or monthly credits** — you get a set number of credits that refresh. Pika (80/month), PixVerse (daily), and Kling (66/day) work this way.
2. **A one-time free trial** — you get an allocation once, and it never comes back. Runway's 125 credits are the classic example.
3. **Open weights** — the model itself is free to download and run. But "free model" doesn't mean free *compute*: you still need a GPU, electricity, and setup time.

Same word, wildly different economics. A platform advertising "free AI video" is usually meaning #1 or #2. A model card advertising "free" is meaning #3 — and it quietly shifts the cost to your hardware.

- **Different cost structure.** No subscription, no per-clip API bill. The cost moves to GPU hardware, electricity, and setup time — which is a *capital* cost you can amortize, not a recurring one.
- **More control.** You can run it in ComfyUI, swap checkpoints, quantize to fit your VRAM, and fine-tune under the community license.
- **It's the model's job to evolve fast.** I tested 2.3; 2.5 shipped a month later with multishot and 4K HDR. Open weights mean you don't wait for a company to upgrade you.

The honest caveats: your results depend heavily on hardware, workflow, model version, and quantization. A hosted playground (like a Hugging Face Space or ComfyUI.cloud) is meaning #4 of "free" — great for a first taste, but queues and quotas can change, and serious local use means learning ComfyUI.

- **Separate video and audio VAEs.** LTX-2.3 generates synchronized audio in the same pass, and it needs its own audio VAE alongside the video VAE — that's the piece that makes the sound *part of* the generation instead of an afterthought.

- **Distilled checkpoint + LoRA.** The fast distilled variant with the distilled LoRA at 0.6 strength, at **24 fps and 5–7 second clips** — the practical sweet spot for LTX.

> A cinematic futuristic night scene in a dense neon-lit city alley during a heavy rainstorm. A young Asian female courier in a dark waterproof jacket, black cargo pants and a compact glowing backpack runs quickly toward the camera, water splashing from her boots with every step, loose strands of wet hair moving naturally in the wind. The shot begins behind and slightly above her as she runs through the narrow alley, then the camera smoothly tracks alongside her and arcs around to the front, revealing her focused face as she looks briefly toward the camera while continuing to run. A small sleek hovering surveillance drone follows several meters behind her, its white searchlight sweeping through the rain. Neon signs reflect vividly across the wet pavement, puddles ripple from raindrops, mist drifts through the alley, and colored light flickers across her face and clothing. The camera movement remains smooth and cinematic with realistic handheld micro-motion, shallow depth of field, natural motion blur and strong foreground-to-background parallax. The final moment shows her rushing past the camera while the drone flies overhead, leaving the camera facing the glowing rainy alley. Realistic cinematic lighting, physically believable rain and water interaction, detailed skin, fabric and wet surfaces, high environmental detail, dramatic science-fiction atmosphere. Audio: heavy rainfall, footsteps splashing through puddles, distant city traffic, subtle electrical ambience and the quiet mechanical hum of the hovering drone.
