Fine-tune Llama 3 on your private data. Keep the weights, eliminate per-token costs, and deploy secure intelligence to your own infrastructure.
Engineered for the world's most powerful open models
"We cut our AI costs by 80% and our support model actually knows our product now. It's the infrastructure we were waiting for."
"Langtrain was the only path for our healthcare data — fully private, SOC2-ready weights in a week."
"I trained a model on 4 years of proprietary research. It's now the backbone of our internal knowledge hub."
Whether you're a lean startup or an enterprise giant, Langtrain provides the infrastructure to own your intelligence.
80% cheaper than cloud APIs. Just as capable.
Private AI, fully on your infrastructure.
Your technical second brain — instantly cited.
Your voice, at scale — trained on your archive.
Langtrain automates the entire lifecycle of private model ownership, ensuring your intelligence remains secure and proprietary.
Upload PDFs, connect Postgres, or point to any URL. Our engine extracts a high-fidelity knowledge graph securely on your private infrastructure.
Supervised fine-tuning on Llama 3 or Mistral. Domain accuracy climbs from 67% to 98%+ by training on your proprietary data.
One command ships your model to WhatsApp, Slack, or a private REST API. No rate limits, no token costs, full weights ownership.
Deploy specialized agents that are fine-tuned on your actual data. They don't guess — they know.
Connect your proprietary knowledge and deploy agents to any channel in minutes. No complex glue code required.
Stop sending your proprietary data to cloud APIs. Langtrain lets you train and deploy models on infrastructure you already own.
Cloud AI providers use your prompts and data to improve their general models. With Langtrain, every optimization stays proprietary.
Every token you spend on a cloud API builds someone else's model. Langtrain turns your AI spend into a permanent asset you own forever.
You pay for every token, data leaves your servers, and you own zero residual value.
Transform AI from a cost center into a sovereign asset that you control and own.
