Choosing Your First AI Model
Learn how to pick the right AI model for your task. Understand the differences between Claude, GPT, Gemini and more.
Choosing Your First AI Model
With so many AI models available, picking the right one can feel overwhelming. This guide helps you understand the differences and make smart choices.
Why Model Choice Matters
Different AI models excel at different tasks. Choosing wisely means:
- Better results for your specific use case
- Lower costs by not overpaying for capabilities you don't need
- Faster outputs when speed matters
The Main Model Families
Claude (Anthropic)
Best for: Long-form writing, nuanced content, complex instructions
Claude Sonnet 4 is excellent for:
- Marketing copy that needs personality
- Content requiring careful tone control
- Multi-step tasks with complex requirements
When to use: Your content needs to feel human, not generic.
GPT (OpenAI)
Best for: Structured outputs, coding, general-purpose tasks
GPT-4o excels at:
- Technical content and documentation
- Data formatting and transformation
- Following precise instructions
GPT-4o Mini is great for:
- High-volume, simpler tasks
- Budget-conscious projects
- Quick drafts and iterations
Gemini (Google)
Best for: Speed, cost-efficiency, simple transformations
Gemini Flash shines at:
- Quick content generation
- Simple rewrites and summaries
- Cost-sensitive bulk operations
DeepSeek
Best for: Maximum value on straightforward tasks

Getting Started
- Start with your task type - What are you creating?
- Consider volume - One piece or hundreds?
- Evaluate stakes - How important is this content?
- Test and compare - Try the same prompt on different models
Common Beginner Mistakes
Using expensive models for everything
Not every task needs Claude or GPT-4o. Start with budget models and upgrade when needed.
Ignoring output quality differences
Cheaper isn't always worse, but it's often different. Test before committing to a model.
Not considering context length
Some models handle longer prompts better. Factor this into your choice.
