Hugging Face Inference Providers vs Relace: key differences
Relace sells utility models that sit beside a frontier model in a coding agent. Its relace-apply-3 merges lazy edit snippets into the original file at about 10,000 tokens per second with 128K tokens of input and output, and Relace says this is over 3x faster and cheaper than a full rewrite. Its agentic search explores large codebases in parallel, and a compaction model runs at 50,000 tokens per second. It offers REST and OpenAI-compatible endpoints, is listed on OpenRouter, and can be self-hosted. Hugging Face Inference Providers serves 132 general chat models across 17 partner hosts, routed by throughput or price, with no markup.
The overlap is small. Relace has no general-purpose model serving, and Hugging Face has nothing tuned for merging edits or compacting agent context. On deployment, Relace offers self-hosting with guided onboarding for enterprises that keep code in-house, while the router depends on partner clouds and adds a network hop plus Hugging Face rate limits. Context limits matter too: Relace returns an error past 128K tokens, so very large files need a fallback, and a router model with up to 1M context, depending on provider, can fill that role. Hugging Face also offers dedicated Inference Endpoints for teams that want their own instances.
What Hugging Face Inference Providers and Relace do
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.
Example models: GLM 5.3, Kimi K3, gpt-oss-120b
Full Hugging Face Inference Providers profileRelace
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.
Example models: relace-apply-3, Relace agentic search
