Sep 23, 2025A: Hi there,
In Tier 3 you’ll have access to GPT-4o directly in PenPilot. You can also use GPT-o1, GPT-o3, and GPT-5, but those require BYOK (bring your own OpenAI API key). GPT-o1 and GPT-o3 are great for reasoning tasks, while GPT-5 is the most advanced model currently and best for high-quality long-form content.
KimchiDeePLUSHi Ahmad — quick ask:
Can GPT‑o1, GPT‑o3 and GPT‑5 be included directly in Tier‑3 instead of BYOK? We need them in‑product for research, legal/complex writing, big docs, and deep analyses.
If not possible, can you briefly say:
- Why not?
- What would be required to include them?
- Any timeline?
Thanks.

Hi KimchiDee,
Great question.
We only include the models we can maintain with unlimited usage, but since a lot of users have asked for the higher-end ones, we decided to make them available through BYOK. You can set this up by creating an OpenAI API key here: https://platform.openai.com/api-keys. You’ll only pay OpenAI directly for what you use, and there are no extra charges from us.
We’ll also be adding more models from Gemini and Claude in the future. The higher-end ones will likely be BYOK as well, since it’s not realistic for us to maintain them under unlimited usage.
I hope that clears things up. I’d be happy to walk you through adding your API key to your account if you’d like.
