AI Workflow Models Get a Major Upgrade in GoHighLevel

GoHighLevel has improved the AI options available inside Workflows by replacing the previous GPT-5.6 models with the new GPT-6 Sol and GPT-6 Luna models. The AI Agent action and GPT action now include both models in the Model dropdown, giving users more flexibility when building automations.

Before this update, GHL users had fewer options when choosing the AI model behind their workflow actions. Now, you can match the model to the task instead of using the same option for every automation. GPT-6 Sol is designed for more complex workflows that require deeper reasoning, while GPT-6 Luna focuses on speed and efficiency for high-volume tasks.

The biggest changes you’ll notice are improved accuracy, cleaner AI responses, and lower costs. GPT-6 Sol is built to handle multi-step business workflows with fewer factual mistakes, while GPT-6 Luna can handle tasks like classification, summaries, tagging, and quick replies at a lower cost. This gives GHL users a better way to build AI automations that fit their actual business needs.

Not every task in GoHighLevel needs the same type of AI power. Some workflows need careful thinking and better decision-making, while others need quick and simple results. The new AI Workflow Models give you more control so you can choose the right option for each automation.

GPT-6 Sol is built for more complex tasks where accuracy matters. It works well for multi-step workflows, detailed lead reviews, and processes that need the AI to understand more information before taking action. GPT-6 Luna is made for speed and volume, making it a good fit for tasks like summaries, tagging, sorting, and quick replies.

The key is not using one model for everything. Match the model to the task. Use GPT-6 Sol when the workflow needs deeper reasoning, and use GPT-6 Luna when you need fast, repeatable results. This helps you build cleaner GoHighLevel automations that work better for your business.

AI is only useful when it helps you save time and get better results. The new AI Workflow Models give GHL users more reliable options for building automations that handle real business tasks. Instead of spending time fixing poor outputs, you can choose a model that fits the job from the start.

With GPT-6 Sol and GPT-6 Luna, your workflows can become more accurate, easier to manage, and more cost-friendly. Better AI responses can help reduce problems like incorrect contact tags, missed details, or replies that need extra editing before they are ready. For agencies, this means more confidence when using AI across client accounts.

These improvements are especially helpful for agency owners, marketers, and teams managing a large number of tasks inside GoHighLevel. Whether you are sorting leads, creating follow-up messages, or handling customer communication, choosing the right AI Workflow Model can help your team work faster while keeping your automations running smoothly.

Choosing the right AI Workflow Model is only part of the process. You also want to make sure each model is being used for the right type of task. Start with GPT-6 Luna for simple, repeatable work such as tagging, summaries, classification, and quick replies. These tasks often run at higher volume, so a fast and lower-cost model can make sense.

Use GPT-6 Sol when the workflow has several steps or needs more careful reasoning. For example, if an AI action needs to review detailed information before deciding what to do next, GPT-6 Sol is designed for that type of work. You can also use different models in the same workflow when each step has a different job.

One more tip: test your workflow before turning it on for a large number of contacts. Review the AI output and check how it moves into the next workflow step. A quick test can help you catch an issue before it affects a larger number of contacts.

The real value of these AI Workflow Models comes from how you use them in your daily workflows. Instead of using the same model for every task, you can match the model to the work. That gives you a simple way to balance speed, accuracy, and cost across your automations.

For example, an agency could use GPT-6 Luna to classify new leads, add tags, or create quick summaries. A later step could use GPT-6 Sol to review more detailed lead information and create a response that needs more careful reasoning. This lets each model handle the type of work it was built for.

The same approach can work across sales, marketing, support, and client workflows. As you add more AI actions to your GHL account, choosing the right AI Workflow Models can help you run more tasks without adding the same amount of manual work. The goal is simple: let AI handle the repetitive work, while your team focuses on the tasks that need a human touch.

The new AI Workflow Models give GoHighLevel users more flexibility when building AI-powered automations. GPT-6 Sol is built for complex tasks that need more careful reasoning, while GPT-6 Luna is designed for fast, high-volume work.

Both models replace the previous GPT-5.6 options and bring improvements in accuracy, response quality, and cost. The key is to match the model to the task instead of using the same option for every workflow.

If you’re already using AI inside GHL, now is a good time to review your existing workflows and see where the new models fit. Start with one workflow, test the results, and adjust from there.
