Lucidic AI

Lucidic AI builds custom language models and agent harnesses trained on a customer's own data. Its approach is to train the model and the surrounding harness together, covering elements such as system prompts, tool descriptions, guardrails, policies, context and memory, rather than tuning model weights alone or optimizing the harness alone. The service is aimed at engineering teams building production AI agents who want performance beyond what an off the shelf frontier model delivers. The company describes its techniques as adaptive simulations, reflective evolution and inference time optimization, and says the combined approach outperforms weight only post training and harness only optimization at lower cost and with less data. The process begins by defining the training surface, meaning which parts of an agent are trainable, and the site lists models from several providers as targets, including GPT, Claude, Gemini and Llama. The site also offers case studies, a research section with published articles, documentation and a careers page. Access is through a sales conversation, with contact and book a demo options on the home page. Pricing is not published. The site lists no plans or prices, and engagements are arranged directly with the company.
