After an expert analysis conducted by AIChief, we concluded that LastMile is a versatile AI-powered platform that helps organizations and enterprises enable fine-tuning of evaluation models, which allows them to test LLM applications. It provides built-in evaluation metrics for RAG and multi-agent AI applications while allowing custom fine-tuning for specialized needs. The platform also includes real-time AI guardrails that allow businesses to detect hallucinations, toxicity, and safety issues in real time.However, we observe that the platform specializes in evaluation and fine-tuning only, which means that the companies need external LLMs for AI generation. Plus, the accuracy of evaluations depends on high-quality and well-structured input data for meaningful insights.
