Merge uses GPT-6 Astra, ChatGPT and Codex

What happened?

In an OpenAI customer story published November 5, Merge describes how it uses GPT-6 Astra, ChatGPT and Codex across product development and business operations. Merge Unified, Agent Handler, Gateway and Merge for Workforce help companies sync data, give AI agents tool access, and control which models and systems employees can reach.

How the models are used

• Codex: CEO Shensi Ding used it to review code for a new provisioning tab in Merge for Workforce; the team made product decisions, and engineers validated and shipped the changes.
• GPT-6 Astra: for product testing and marketing; Ding says it is faster and stronger at code review, and better at carrying multi-step tasks without dropping earlier instructions.
• Tool choice: Merge lets employees pick their own AI tools, and which one to use is an active internal debate.

Dinner bot and sales

For a Dallas executive dinner, the bot started from the city and guest profile, pulled candidates from CRM and Apollo, checked prior invitations, and helped with outreach and seating. Ding reviews copy and relationship context; hosting and networking stay human.

In October, Merge said guest lists, outreach and the attendee tracker dropped from dozens of hours across the company to about 30 minutes per event versus the same tasks over the prior three months. It ran 16 executive dinners in Q3 (8 in Q2) and plans more than 30 in Q4. On sales, Charlie Lynch built reusable AI workflows for deal approvals, forecast updates and next steps after renewal calls.

Why it matters

This is not a new model launch, but a concrete, measurable internal AI rollout: Merge cites 99.9% tool-call success on its connectors versus about 60% for public MCP servers in the piece, and the dinner bot cuts hours from BD prep. For developers, Codex and GPT-6 Astra show up together in product review; on the business side it shows models wired to Salesforce, Gong, Sheets and Gmail through Merge connectors.
