Hi everyone, where can I get the free gpt4.1api? I want to do some research, but I found that the price is very expensive. Is there any special plan discount or related research that can be provided for free?
For short time here:
EDIT:
All info about 4.1:

Thanks, but I think what I need is the API, so I’m still looking for it. Thank you very much for your reply.
There is no “the free API” - but the pricing can certainly go lower, lower than gpt-3.5-turbo with “nano”, and especially with a growing chat of turns being cached, now a 75% discount on cache-matching inputs.
| Model | Input ($/1 M tokens) | Cached Input ($/1 M tokens) | Output ($/1 M tokens) |
|---|---|---|---|
| gpt-4.1 | $2.00 | $0.50 | $8.00 |
| gpt-4.1-mini | $0.40 | $0.10 | $1.60 |
| gpt-4.1-nano | $0.10 | $0.025 | $0.40 |
What are you going to do with your 10 million tokens of input for $1.00 today?

I’m testing some calculations, and to be honest, only 4.1 is OK, and one process costs about $0.3
