xAI vs Runware: key differences
Runware is a media company that also serves some text. Its API covers image, video, audio, 3D and text with one task shape, and its rate sheet lists 300+ priced models, from images at fractions of a cent to video like Seedance 2.5 at about $0.10 a second at 480p. xAI is a text lab first. Grok 4.6 handles everything outside audio, image and video, and xAI ships separate first-party APIs for those media types. Runware says LLM hosting is a side line, so text workloads fit better elsewhere.
Teams building consumer media apps can use both. Grok can write prompts, captions or scripts, drawing on trending posts through X Search, and Runware can generate the images or clips at volume, with many tasks batched in one call. Runware's output URLs expire after seven days by default, so apps need their own storage. xAI's own media APIs are the simpler choice when one vendor for text and media matters more than catalog size or per-generation price.
What xAI and Runware do
xAI
xAI sells the Grok models through its own API. Grok 4.6 is the current flagship and xAI tells developers to use it for everything outside audio, image and video, code included. It has a 500K context window and costs $2 in and $6 out per million tokens under 200K prompt tokens. Older Grok 4.20 and 4.3 models keep a 1M window at $1.25 in and $2.50 out, which is aggressive for that capability class.
Example models: Grok 4.6, Grok 4.20
Full xAI profileRunware
Runware sells what it calls the lowest-cost API for media generation, and it claims more than 1M developers. One endpoint covers image, video, audio, 3D and text. Every request is a task with the same shape, so switching from a Kling video to a Seedream image mostly means changing the model ID. The published rate sheet lists 300+ priced models, with images from fractions of a cent to a few cents each and video billed per second, like Seedance 2.5 at about $0.10 a second at 480p.
Example models: Seedance 2.5, Qwen-Image-3.0
