## How they compare

Runware and Wafer each claim a cost or speed edge from how they build infrastructure, but for different model types. Runware's Sonic Inference Engine pairs custom hardware and software, with pods of about 1 MW per container that Runware says cut capital cost 90% against a traditional data center, and a Model Lake that keeps 400K+ models resident. That supports media generation at low prices across image, video, audio and 3D. Wafer's agents tune serving stacks for large open text models, and it reports Qwen 3.5 397B running 2.8x faster than stock SGLang.

Pick by modality. Consumer apps generating images or short video, and teams serving fine-tuned diffusion checkpoints, fit Runware, which treats LLM hosting as a side line. Coding agents wanting big open models at interactive speed, through Wafer Pass from $10 a week or a dedicated deployment tuned to an SLO, fit Wafer. Both rely on self-reported numbers for their headline gains. Wafer is a very young company with a small catalog, and Runware's outputs expire after seven days unless stored elsewhere.

## What each one does

### 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.

### Wafer

Wafer builds AI agents that act as GPU performance engineers, then sells inference on the stacks those agents tune. The company came out of Y Combinator's Summer 2025 batch as a "Cursor for CUDA" that turned slow PyTorch into custom kernels. Founders Emilio Andere and Steven Arellano are based in San Francisco. Its agents profile a workload, generate candidate configs across batching, decoding, quantization, engines, kernels and hardware, measure each one and deploy the winner.
