How to Give an LLM Agent a Browser

Recent developments focus on enhancing LLM agents by integrating browsers using OpenAI Agents SDK and Playwright MCP. Simultaneously, the industry is adopting LLM Eval Pipelines to address silent semantic failures. Unlike standard unit tests, these evals manage non-determinism and temperature-driven randomness, ensuring output quality. This approach prevents quality drift and overcomes the limitations of string matching by programmatically assessing factual accuracy and tone, which is essential for scaling AI applications effectively in 2026.
