## How they compare

There is almost no overlap here. Relace trains small models that act as tools for coding agents, such as relace-apply-3, which merges lazy edits at about 10,000 tokens per second, plus agentic codebase search and a 50,000 tokens per second compaction model. Runware sells media generation across 300+ priced models behind one request schema, with images from fractions of a cent and video billed per second, like Seedance 2.5 at about $0.10 a second at 480p. Runware lists text as a modality but calls LLM hosting a side line.

The only realistic shared product is an app builder that generates both code and media. Relace would apply AI edits to the user's codebase, and Runware would generate images or clips for the app itself, batching many tasks in one call. Each has its own gotcha: Relace returns an error past 128K tokens, and Runware's output URLs expire after seven days by default. Pick by the job, since neither can stand in for the other.

## What each one does

### Relace

Relace trains small, fast models that act as tools for coding agents. Its best-known product is Instant Apply: a frontier model writes a lazy edit snippet, and relace-apply-3 merges it into the original file at about 10,000 tokens per second with 128K tokens of input and output. Relace says this runs over 3x faster and cheaper than having the big model rewrite the file. It exposes both a REST endpoint and an OpenAI-compatible one, and the model is also listed on OpenRouter.

### Runware

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.
