NLP Cloud
NLP Cloud serves pre-trained and fine-tuned NLP/LLM models over a single REST API for tasks like named-entity recognition, sentiment analysis, summarization, translation, and text or code generation, with an option to deploy your own custom model on dedicated infrastructure. The company's site has moved from nlpcloud.io to nlpcloud.com, but the underlying api.nlpcloud.io hosts remain live and respond with permissive CORS headers. Plans range from a free CPU tier for testing up to metered, GPU-backed production tiers.
