# ZeroGPU > ZeroGPU is the compute efficiency layer for AI inference. It runs repeatable, high-volume tasks - classification, extraction, PII redaction, moderation, summarization, routing - on specialized small and nano language models across an edge-powered network, faster and cheaper than centralized GPUs, through one OpenAI-compatible API. ## Docs - [Introduction](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/index.md): Run high-volume AI tasks on specialized small and nano language models across an edge-powered network - faster and cheaper, through one OpenAI-compatible API. - [How ZeroGPU works](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/how-zerogpu-works.md): ZeroGPU turns idle compute into one programmable inference layer - specialized small models, an edge-powered network, and routing handled for you. - [Quickstart](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/quickstart.md): First API call in minutes. - [Model Catalog](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/model-catalog.md): Browse ZeroGPU models, compare pricing, and pick the model ID to call. - [Ad Tech](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/ad-tech.md): Edge IAB classifiers that map content to taxonomy, audience, and intent signals for programmatic advertising. - [Text Classification](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/text-classification.md): Edge models that map text to labels, IAB taxonomy, and audience signals. - [Text Generation](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/text-generation.md): Edge generative models for conversation and reasoning. - [PII](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/pii.md): Multilingual PII detection, redaction, and schema-driven extraction models. - [Summarization](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/summarization.md): Models tuned to condense long content into concise summaries. - [Overview](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/batch/index.md): Run large workloads of AI inference asynchronously, wire-compatible with `/v1/batches` and `/v1/files`. - [Quickstart](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/batch/getting-started.md): First batch in under 10 minutes, auth, upload, create, poll, download. - [Objects & lifecycle](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/batch/objects.md): The File and Batch objects, the batch status lifecycle, and how the two APIs fit together. - [JSONL Format](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/batch/jsonl-format.md): Mandatory line schemas for input, output, and error JSONL files. - [Supported Endpoints](https://zerogpu-docs-langchain-video-walkthroughs.mintlify.site/docs/batch/supported-endpoints.md): The only endpoint a batch line can target.
