IBM watsonx.ai

What is IBM watsonx.ai?

IBM watsonx.ai is a studio for building AI applications end to end. Developers work with foundation models in a playground and in Prompt Lab, build agents in Agent Lab, use retrieval-augmented generation, generate synthetic data, fine-tune with LoRA and QLoRA, and deploy custom or on-demand models. The model catalog includes IBM Granite models plus third-party models from Meta, Mistral, DeepSeek and others, priced per million tokens or per hour for hosting. The Studio side adds Jupyter notebooks, SPSS Modeler, AutoAI, Data Refinery and Spark environments for classic machine learning. A Free plan includes up to 300,000 foundation-model tokens per month, 20 compute usage hours for machine learning tools and 100 documents of text extraction. Enterprise production starts at USD 1110 per month, embedding models are USD 0.10 per million tokens, and advanced support with SLAs starts at USD 200 per month.
