# Hugging Face Inference Providers vs Wafer

> Wafer tunes its own inference stacks to run open models faster on the same weights. Hugging Face routes each model to whichever partner is fastest.

## How they compare

Both promise speed, by different means. Hugging Face Inference Providers picks the highest-throughput partner for a model by default across 17 hosts and 132 chat models, billing at provider rates. Wafer uses AI agents as GPU performance engineers: they profile a workload, try configs across batching, decoding, quantization, engines, kernels and hardware, and deploy the winner. Wafer reports its tuned Qwen 3.5 397B at 2.8x stock SGLang, with GLM 5.1 and DeepSeek V4 Pro each 2x faster than a vLLM baseline. Those are self-reported numbers against stock baselines, and tuned hosts like Fireworks, one of Hugging Face's partners, make a fairer comparison.

Pricing models differ sharply. Wafer Pass is a flat-rate subscription from $10 a week that covers every hosted model and plugs into Claude Code, Cline and OpenHands, which suits heavy agentic coding. Dedicated deployments get re-tuned as load, models or hardware change, on NVIDIA or AMD. Hugging Face bills per token at each provider's rate with no subscription, which favors light or bursty use, and offers far more models plus failover. Wafer is a very young company with a small hosted catalog. The router has no fine-tuning or tuning service, and its extra network hop may offset some of the gain from picking the fastest host.

## What each one does

### Hugging Face Inference Providers

Inference Providers is a router run by Hugging Face that sits in front of partner inference clouds. The current partner list covers Baseten, Cerebras, Cohere, DeepInfra, fal, Featherless AI, Fireworks, Groq, Novita, Nscale, OVHcloud, Public AI, Replicate, Scaleway, Together, WaveSpeedAI and Z.ai, plus Hugging Face's own HF Inference, which now mostly serves CPU workloads like embeddings and classification. Chat traffic goes through an OpenAI-compatible endpoint at router.huggingface.co/v1, and the Python and JavaScript clients add text-to-image, video, speech and embeddings. The router lists 132 chat models today, from GLM 5.3 and Kimi K3 to gpt-oss-120b on eleven providers.

### 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.
