Hello @Juan Pablo Olguin
Thanks for reaching out to us, I just checked with product team about the availability of fine tuning, unfortunately at this moment fine tuning is disabled for all new customers in all regions, unless previously approved using fine tuning (as in actually deployed and had a fine tuning job running).
Currently there is no exact time for when fine tuning opens again, I will let you know once there is any update.
Sorry for all the inconveniences.
Regards,
Yutong
