We engineer and tune foundation models are a form of generative artificial intelligence (generative AI). We generate output from one or more inputs (prompts) through human language instructions. Models are based on complex neural networks, including generative adversarial networks (GANs), transformers, and variational AI foundational models engineering is developing and maintaining large language models (LLMs) that can be used to power various AI applications. These models are typically trained on massive datasets of text and code, and they can be used for tasks such as natural language understanding, machine translation, and text generation.encoders.
