ChatGPT for quick research
Integrated native web search, real-time data access, and the ability to browse the internet directly. Ideal for Research and fact-checking on current topics.
Claude for long documents
1M tokens of context without surcharge de precio. Puedes subir contratos completos, bases de código enteras o manuscritos de libros y analizarlos en una sola conversación sin perder información.
ChatGPT for automations
GPT Store with thousands of custom GPTs, native integrations with Microsoft Office, Zapier and Slack. If your workflow depends on enterprise tools, ChatGPT connects better.
Claude for sensitive data
Certifications SOC 2 Type II and ISO 42001. Both platforms use data for training by default (opt-out available), but at the enterprise level, both guarantee that data is not used for training.

How to choose between Claude and ChatGPT in 5 steps
- Define your main task — Do you need to generate images or use voice mode? Go with ChatGPT. Do you need to analyse code or extensive documents? Go with Claude. If you do both, you need both.
- Review your budget — Both cost $20 per month on their basic plan. If you can only afford one, choose the one that best suits your main use case. The free versions of both are sufficient for testing.
- Consider your ecosystem — Do you use Microsoft Office and Slack? ChatGPT integrates better. Do you work from the terminal or with APIs? Claude Code and MCP are superior.
- Think about privacy — If you handle customer data, medical or legal information, both offer an opt-out from training. At an enterprise level, neither uses your data for training. Review each of their policies.
Detailed API pricing (for developers)
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Context |
|---|---|---|---|
| GPT-5.4 Standard | $2,50 | $15,00 | 1.05M tokens |
| GPT-5.4 Mini | $0,75 | $4,50 | 400K tokens |
| GPT-5.4 Nano | $0,20 | $1,25 | 400K tokens |
| Claude Opus 4.6 | $5,00 | $25,00 | 1 million tokens |
| Claude Sonnet 4.6 | $3,00 | $15,00 | 1 million tokens |
| Claude Haiku 4.5 | $1,00 | $5,00 | 200k tokens |
Cost note: GPT-5.4 is cheaper per token in its standard model ($2.50 vs $5 input). However, GPT-5.4 prompts exceeding 272K tokens incur a 2x surcharge on input and a 1.5x surcharge on output. Claude charges a flat rate regardless of prompt size, making it more predictable for tasks involving extensive context.
The smart strategy: use both
Practical tip: Most professionals who work with AI on a daily basis use the two platforms. ChatGPT for creating images, finding up-to-date information and automating tasks through integrations. Claude for writing high-quality text, programming, analysing documents and tasks requiring in-depth reasoning. For $40/month ($20 each), you get access to the best of both worlds. If your budget is limited, start with the one that meets your main need and add the other when you need it.

Common mistakes when choosing between Claude and ChatGPT
- Choosing solely by benchmarks: Benchmarks measure specific tasks, not your actual workflow. Two models with similar scores can feel very different in practice. Always test with your own tasks.
- Assuming the most expensive is best: The $200/month plan (Pro on both) isn’t 10 times better than the $20 plan. For most users, the standard plan is more than enough.
- Ignore the free versions Both ChatGPT and Claude offer free access. Before paying, try both for at least a week with your actual tasks.
- Do not review the privacy policy If you're working with customer data or sensitive information, the difference in how each platform uses your data matters a great deal. Read the policies before uploading confidential information.
- To be left with outdated information: These models are updated every few weeks. What was true in January 2026 may not be true in March. Always verify the current version before deciding.
