When building AI-powered workflows, choosing the right model for the job is key to balancing performance, cost, and speed. You can think of each of these models as a separate brain; just like you and your team, each model has something different it excels at!
At Copy.ai, we support the latest models from Anthropic, OpenAI, and Perplexity—each optimized for different use cases. The best part? We make it easy to get the benefits of all of them in one place. Here's how to choose smartly:
🧠 For High Reasoning & Complex Tasks
Best for lead scoring, research, technical content from long documents, and logic-heavy workflows that require complex and nuanced output and highest accuracy:
Claude 3.7 Sonnet – Anthropic’s most powerful model for highly knowledgeable content generation, also considered a great resource for tasks like coding and narrative structure
GPT-o1 – OpenAI’s most powerful model with deep reasoning capabilities for the highest degree of nuance and intelligence
Claude 3 Opus – Anthropic’s previous best-in-class which still absolutely meets the mark for difficult tasks
Perplexity Sonar – Perplexity specializes in helping you research by getting you the best results from the web and distilling them into the things most relevant to you. This model is not so chatty, so the best way to try it out is by using the Research Agent action!
⚙️ For Everyday Power & Versatility
Balanced, tried-and-true models for content generation, campaign building, and intelligent automation:
Claude 3.5 Sonnet – A creative, fast, and bright model for daily work
GPT-4o – A reliable general-purpose model with enhanced logical reasoning
OpenAI O3-mini – One of OpenAI’s newest additions: lightweight, intelligent, and great for scalable use in accomplishing simple tasks rapidly with nuance.
⚡ For Speed, Scale, and Simplicity
Perfect for real-time tasks, high-volume flows, and cost-efficient automations, these models are best for simple, repeatable tasks with well-understood return requirements. They may not be as “smart” as their bigger siblings, but don’t be fooled: these little models can pack a big punch! For the most part, you’ll be just fine using general purpose models, but if you really care about speed, try these out:
Claude 3.5 Haiku – Fast, low-cost model for simpler workflows
Claude 3.5 Haiku-mini – Super lightweight and speedy for basic tagging and summaries
GPT-4o-mini – Optimized for quick responses and high-efficiency needs
🧩 Build Smart: Use the Right Model for Each Step
Here’s a winning combo you can always count on:
Use GPT-o1 to analyze complex input and create a strong messaging plan
Use Perplexity via the Research Agent to supplement that analysis with extra research
Use GPT o3-mini to extract or summarize small pieces to be called out: key names, dates, locations, etc. You can do this even faster by using the Extract Data from Text action and selecting Reasoning Models in the advanced option. It uses o3-mini under the hood!
Use Claude 3.7 Sonnet to generate marketing content based on your findings while adhering to your brand guidelines
Copy.ai’s platform makes multi-model orchestration seamless, so you can optimize for quality and cost across your entire workflow. Best of all: changing models is as simple as clicking a button!
