Which AI Model Should You Use? GPT-4 vs Claude vs Gemini

Not all AI models are created equal. We break down the strengths and weaknesses of each to help you choose.

Share:

The Big Three

GPT-4 (OpenAI)

Best for: General purpose, coding, reasoning

  • Pros: Best coding, strong reasoning, huge ecosystem
  • Cons: Expensive, slower
  • Cost: ~$15-75/1M tokens

    • Claude (Anthropic)

    Best for: Long context, nuanced tasks

  • Pros: 200K token context, excellent writing, careful reasoning
  • Cons: Smaller ecosystem
  • Cost: ~$15-75/1M tokens

    • Gemini (Google)

    Best for: Multimodal, integration with Google

  • Pros: Native multimodal, Google integration, fast
  • Cons: Still maturing
  • Cost: ~$0.50-1.50/1M tokens

    • How to Choose

    For Customer Support

    Start with Claude — long context helps with complex conversations.

    For Code Generation

    GPT-4 leads here, but Claude is catching up fast.

    For Multimodal (images, video)

    Gemini or GPT-4 Vision.

    For Cost-Sensitive Workloads

    Gemini Flash or GPT-4o-mini.

    Our Recommendation

    Start with GPT-4 for most use cases. Switch to Claude for long documents. Use Gemini when cost matters most.
