What changed

• OpenAI's GPT-6 Sol and GPT-6 Luna models are now available for selection within the AI Agent action and the GPT action in Workflows.
• These new models directly replace the older GPT-5.6 models.
• Pricing for GPT-6 Sol and GPT-6 Luna is 50 percent lower than for the GPT-5.6 models.
• GPT-6 Sol makes approximately half as many factual mistakes compared to GPT-5.6 Sol.
• GPT-6 Luna achieves factual accuracy on par with GPT-5.6 Sol when used at higher effort settings.
• GPT-6 Luna can deliver improved results at up to 58 percent lower cost per task.
• HighLevel has not confirmed any limits or specific plan gating for these new models. HighLevel has not confirmed the rollout status.

Where to find it

The new models can be selected within the Model dropdown menu. This dropdown is located inside the AI Agent action and the GPT action within your Workflows. The navigation path is: Workflows > AI Agent action or GPT action > Model dropdown.

How agencies will use this

An agency might use the new GPT-6 Sol model to improve lead qualification in a workflow. Imagine a workflow triggered by a new form submission from a potential client. An AI Agent action could receive the form data and, using GPT-6 Sol, analyze the submitted details to determine lead fit based on predefined criteria, reducing factual errors by half. This AI assessment then feeds into a conditional branch: if the lead is highly qualified, an internal notification is sent to the sales team for immediate follow-up. If the lead requires nurturing, the workflow proceeds to assign them to a specific email sequence. This allows the agency to process more leads efficiently and accurately, ensuring sales focuses on the best prospects while saving on AI processing costs.

Our take

This is a major update for agencies leveraging AI within HighLevel Workflows. The combination of significantly reduced pricing (50% lower than GPT-5.6 models) and improved factual accuracy (GPT-6 Sol makes half as many errors, and GPT-6 Luna matches GPT-5.6 Sol accuracy at lower cost) provides a clear advantage. Agencies running AI-powered lead qualification, content generation, or customer support automation within Workflows can expect better performance at a lower operational cost. This directly impacts profitability and the efficiency of client services. It's not a small change; evaluate your current AI workflows to take advantage of these new capabilities and cost savings.
