Mostly credit or subscription-based rather than pure pay-per-image — Midjourney, Ideogram, Recraft-style tools bundle a monthly generation allowance. API-first tools (DALL-E, Stable Diffusion, Flux) charge per image, typically $0.02–$0.08 depending on resolution and model tier.
The most expensive modality — priced per second of output rather than per clip. Consumer subscriptions (Runway, Luma, Pika, Kling) convert a monthly credit allowance into seconds of video; API access (Google Veo) charges directly per second, which adds up fast for longer clips.
Voice cloning/TTS (ElevenLabs) bills by character count; music generation (Suno, Udio) bills by song credits. Cheapest modality to get started in — most have a usable free tier, unlike image and video.
