Models to update
| Model ID |
Current status |
Shutdown date |
Replacement |
gpt-5.2-chat-latest |
No deprecation flag |
2026-08-10 |
gpt-5.5 |
gpt-5.3-chat-latest |
No deprecation flag |

gpt-5.5 |
Suggested change
Add deprecation_date and parent (replacement) fields to each entry. The codebase already has markModelsPastDeprecationDate() in packages/proxy/schema/models.ts which automatically sets deprecated: true when the current date exceeds deprecation_date.
For gpt-5.3-chat-latest (line ~216):
"deprecation_date": "2026-08-10",
"parent": "gpt-5.5"
For gpt-5.2-chat-latest (line ~297, already has parent: "gpt-5.2"):
"deprecation_date": "2026-08-10",
"parent": "gpt-5.5"
