September Product Update

Evaluate workflow changes with datasets and experiments, read clearer node summaries, and connect new tools for meetings, operations, and more.

Highlights

Evaluate workflows with repeatable test cases

Build a dataset, attach evaluators, and run an experiment against a workflow version. Review scores alongside each input, expected answer, and actual output to see where changes improve quality and where they introduce regressions.

Understand your workflow at a glance

Redesigned LLM nodes put the model up front and group tools, knowledge, and MCP servers in one row. Code, Files, Audio, Search Tables, and Text-to-SQL nodes also summarize their configuration directly on the canvas.

Improvements

Inline images in Microsoft Teams

Bot replies render images as rich cards and preserve the order of text and pictures.

More steps for browser tasks

Browser agents support up to 120 steps per task, with a default of 30.

Split files into a set number of parts

Choose the number of parts in the Split Files node to divide a batch evenly across downstream work.

Citations across sub-workflows

Citations pass through the Project node (beta) and the Read Knowledge Base File action, preserving sources in downstream answers.
