fal vs Wafer: key differences
Wafer builds AI agents that act as GPU performance engineers, then sells inference on the stacks they tune. It reports its Qwen 3.5 397B running 2.8x faster than stock SGLang, and bills serverless use per token for coding tools like Claude Code and Cline. fal serves generative media: 1,000+ image, video and audio models priced per output, with an async queue built for long renders. Wafer is about making big language models fast. fal is about making media generation easy to call.
Each sells dedicated or custom compute as a step up. fal offers serverless GPUs at $4.50 an hour for H100s when teams outgrow hosted models. Wafer builds dedicated deployments around a customer's model, traffic shape and SLO, and keeps re-tuning them on NVIDIA or AMD. Wafer is very young with a small hosted catalog, and its speedups are self-reported. The choice follows the modality: text agents to Wafer, media to fal.
What fal and Wafer do
fal
fal is the go-to inference platform for generative media. It hosts 1,000+ image, video and audio models behind one API, including FLUX, Kling, Seedream and other video models, and new releases often land there before competitors have them. Every model page exposes its schema, a playground and example code. Pricing follows the output: per image or megapixel for images, per second or per clip for video, and GPU time for custom work.
Example models: FLUX, Kling
Full fal 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

Running long-horizon agents?
If your agents run past 200K tokens, compare both against Subconscious. Our inference stack treats a long-horizon trace as the primary workload, so speed, cost, and accuracy hold up deep into the trace.
