"Why are these charges still accruing despite the deletion of the deployments?:"
It could be due to hosting costs, pending charges or still active resources
"Can someone explain what each of these specific charges means and how they relate to deleted resources?"
Based on their names:
gpt-4-0806-FT-Hstng-glbl ($75): Likely a global hosting fee
gpt-4-0806-FT-Hstng-regnl ($68.93): Regional hosting fee tied to the specific Azure region where the deployment was hosted.
"How to ensure all associated resources with the deleted models are completely terminated?"
Use Cost analysisto identify all resources linked to the deleted model.
