Does PIES provide a private, customer-trainable LLM? 

Yes. The three-tier AI engine gives enterprises genuine optionality: 

• Anthropic Claude – frontier reasoning, up to 1M context window, for the hardest tasks.
• OpenAI / Azure OpenAI – cost and speed-optimised for high-volume generation workloads.
• PIES Private LLM – Llama-based, running on the customer’s own hardware, with LoRA fine-tuning capability. No per-token billing, no data leaving the building, and a model that gets progressively better at your specific work.

The LoRA fine-tuning point is significant: an enterprise can continuously train the private model on their accepted code outputs, domain terminology, and workflow patterns -building a proprietary AI asset over time.
