Image engines
Used for the cover image. Good defaults, and a few special-purpose picks:
- ChatGPT Image (GPT-4o) — default. Versatile, great for people and scenes.
- Nano Banana (Gemini 2.5 Flash) — best for consistent characters across scenes.
- Seedream 4.5 — also excellent for character consistency and realism.
- Flux Pro Ultra — highest quality cinematic/artistic images.
- Ideogram V3 — best at text/typography in the image.
- Recraft V3 — great for illustration and brand assets.
Video engines
Used for the film. Most give cinematic motion — the main differences are speed, realism, and style:
- Sora 2 (OpenAI) — default. Strong, expressive motion.
- Veo 3 (Google) — premium, cinematic realism.
- Seedance 2.5 / 2.0 — advanced, controllable motion.
- Kling 1.6 — great motion and realism.
- Wan, MiniMax, LTX, Hunyuan, Runway, Pika — more styles and speeds.
Language models
Used for the writing. Pick by quality or speed:
- GPT-4.1 — default, best prose.
- Claude Sonnet 4 / Opus 4 — strong reasoning and writing.
- Gemini 2.0 Flash — fast and reliable.
- o3-mini / GPT-4o mini — fastest and cheapest.
