Body

In managing model, I select Open-AI, then put in a project key, after that I can only see O4-mini. However, in Open-AI end, I allowed for both O4-mini and O3 for this project. I'm on Tier-3 in Open-AI. When O3 was initially launched only Tier-5 can use it in API but I believe now it is not the case any more. I would like to know how to enable O3 in BYOK mode. I'm on Copilot Pro tier, which don't have O3 to select by default in Copilot.

This is a nuanced question, so here’s a breakdown tailored to your situation across OpenAI, Copilot, and VS Code:

🔍 Your Setup Summary
Copilot Feature Area: VS Code

Provider: OpenAI (Bring Your Own Key - BYOK)

Tier: Tier-3 on OpenAI API

Copilot Tier: Copilot Pro

Goal: Use gpt-4o and gpt-3.5 (aka O4-mini and O3) via OpenAI API in BYOK for VS Code Copilot

Problem: You only see O4-mini, even though O3 access is allowed on the OpenAI end

generally correct, expect that I'm not interested in non-reasoning models here. I specifically need to use O3 via OpenAI API.
