Best LLMs for Agency Automation: GPT-4o vs Claude vs HighLevel

Agencies don’t just need "smart" AI; they need AI that can *do* things. Generating text is easy. Executing workflows, sending emails, and updating CRMs is where the real value lies.

HighLevel (Workflow AI)
Automate Agency Tasks

HighLevel doesn’t just give you a text box; it gives you an "Action" engine. Its internal AI is fine-tuned to execute agency tasks: "Read this email, detect sentiment, if positive, book appointment." It uses the best models (like GPT-4) under the hood but wraps them in *action*.

Pros

  • Executes Actions (booking/tagging)
  • Fine-tuned for Sales & Support
  • No "Prompt Engineering" required
  • Integrated with SMS/Email

Cons

  • Less "creative writing" freedom than raw ChatGPT

OpenAI GPT-4o

The smartest "raw" model. Incredible for reasoning and complex writing, but you need to copy-paste or build API connections to make it do work.

3
Claude 3.5 Sonnet

The best for coding and human-like writing. If you need to write long blogs, Claude is superior, but it can’t see your CRM data.

4
Google Gemini 1.5 Pro

Great for massive context windows (reading huge documents). Useful for analyzing client contracts but not for day-to-day automation.

5
Llama 3 (Meta)

The best open-source model. Great if you want to host your own privacy-focused AI, but requires technical infrastructure.

6
Perplexity

Not an LLM but an answer engine. Amazing for research, but it cannot execute agency workflows.

7
Jasper

Built on top of upgrades, Jasper is great for writing marketing copy, but HighLevel’s Content AI now matches most of its features for free/cheaper.
