One API for fast, cost-predictable inference on LLMs and multimodal models
Access a large catalog of LLMs and multimodal models through a single endpoint, so most existing SDK code works after swapping the base URL and key.
Start with pay-per-use serverless calls, then move to dedicated endpoints, reserved H100/H200/MI300 GPUs or elastic GPU (FaaS) deployment as throughput and cost requirements grow.
Customize supported models on your own data and push the tuned variant to a hosted endpoint without building a training pipeline from scratch.
Transparent rate tables list input, cached-input and output prices per million tokens, plus per-image rates for generation models, making budget planning concrete.
AI content detection and a full writing toolkit in one place
Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
