Host: Scott Abel

Drawing from real-world implementation experience at scale, this presentation explores how LLM-infused translation is revolutionizing technical documentation localization across multiple languages. The presenters will  share comprehensive insights from production pilots, comparing performance metrics of various LLM approaches in both direct translation and post-editing scenarios. Through detailed analysis of BLEU, COMET, and human evaluation metrics, we’ll examine cost-effectiveness, quality improvements, and practical implementation strategies. Attendees will gain actionable insights into selecting evaluation methodologies, optimizing workflows, and implementing LLM solutions while addressing critical considerations like information security, testing requirements, and deployment timelines for enterprise-scale technical documentation.

Key Takeaways:

LLM post-editing demonstrates 15% cost reduction in production, with additional savings potential through integrated LLM workflows including direct translation and automated quality estimation; balanced evaluation approach combining BLEU/COMET metrics with human assessment provides most reliable performance indicators for LLM implementation; enterprise LLM deployment requires systematic security protocols including data handling procedures, output validation, and continuous risk assessment.
