Runware vs Wafer: key differences
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 its per-token API 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 Runware and Wafer do
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.
Example models: Seedance 2.5, Qwen-Image-3.0
Full Runware profileWafer
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. Wafer raised a $4M seed led by Fifty Years in April 2026 and a $40M Series A co-led by Marathon and Chemistry in September 2026 at a $220M post-money valuation, with AMD Ventures and Wing joining. Its agents profile a workload, generate candidate configs across batching, decoding, quantization, engines, kernels and hardware, measure each one and deploy the winner.
Example models: GLM-5.3, DeepSeek V4.1 Flash
