Should You Switch from GPT-4?
If you're using GPT-4 for legacy applications requiring gpt-4 specifically, there are likely better-value options available. The cheapest alternative saves up to 90% on your API costs while maintaining comparable quality.
For tasks requiring more reasoning depth, consider the models in the "More Capable" section above. The premium you pay buys significantly improved accuracy and problem-solving capability.
Frequently Asked Questions
Why is GPT-4 so expensive?
GPT-4 is one of the oldest models still in the pricing database at $30/M input. It's been superseded by GPT-4o, GPT-4.1, and o-series models that are all cheaper and better.
Should I still use GPT-4 in 2026?
No. GPT-4.1 is newer, more accurate, and costs 93% less. There is no reason to use GPT-4 in 2026.
What's the best replacement for GPT-4?
GPT-4.1 is the direct replacement — same lineage, improved accuracy, and $2.00/M vs $30.00/M.
