GPT‑6 Astra helps Hex’s data agents turn answers into interactive visualizations that employees are proud to share.

“A really important part of data work is not just doing the analysis, but also communicating it,” says Caitlin Colgrove, co-founder and CTO of Hex, an agentic data platform. But according to Caitlin, “Models have struggled with data visualization for a really long time.” GPT‑6 Astra changes that.

Producing a useful data visualization requires both technical work and choices about how to present the result. Caitlin remarks on how well GPT‑6 Astra works with the underlying libraries and performs the data transformations required, helping analysts create functional, visually appealing outputs.

For example, a Hex user can ask how sales channels are performing over time, which are doing best, and which should be discontinued. Hex presents written findings alongside trend lines and comparisons, as well as interactive dashboards that let users explore key measures, rankings, and geographic breakdowns.

Even technically correct code can produce an answer that misses the point, so Hex uses GPT‑6 Astra to interrogate the answer: Does the number make sense? Does the analysis answer the user’s question? Does it reflect the business objective?

Caitlin says GPT‑6 Astra investigates more thoroughly, uncovers more of the data’s pitfalls and nuances, and delivers a more comprehensive analysis than earlier models.

A clear visualization gives colleagues a way to engage with the analysis: comparing results, following changes over time, and exploring the details that relate to their work.

With GPT‑6 Astra, Hex users can access, understand, and communicate data more easily, bringing Hex closer to its mission of making everyone a data person.
