The problem
Generic LLMs hallucinate product-specific answers, can't access your knowledge base, and require sending sensitive customer data to OpenAI or Anthropic. Every wrong answer costs you a customer.
How Langtrain helps
Purpose-built for Support & CX.
Domain-Specific Accuracy
Fine-tune on your actual product documentation, past resolved tickets, and internal knowledge base. Your model knows your product, not generic platitudes.
Data Privacy
Customer PII never leaves your infrastructure. Open weights you run in your own VPC mean no third-party AI provider sees the data.
Instant Escalation
Intelligent routing to human agents when confidence is low or sentiment signals frustration. No dead-end bot experiences.
Multilingual
Open models such as Qwen and Llama are trained on many languages. Fine-tune on conversations in the languages your customers use.
Checked Before It Ships
Score the fine-tuned model on held-out tickets before it answers a single customer.
Works With Your Stack
Serve it with vLLM behind an OpenAI-compatible API, so your helpdesk backend and existing tools can call it.
Applications
What teams actually build.
- 01
Tier-1 Ticket Deflection
Train on your top 500 most common issues. The model handles password resets, billing questions, and basic troubleshooting without any human involvement.
- 02
Internal Agent Assist
Deploy as a co-pilot for human agents. The model surfaces relevant KB articles, suggests responses, and flags policy violations in real time.
- 03
Proactive Support
Integrate with product telemetry — when a user hits an error, the agent proactively opens a chat with the relevant solution.
- 04
Returns & Refunds Automation
Automate the full returns flow: validate eligibility, initiate RMA, update CRM, and send confirmation — all in one agent conversation.
