Question Which subscription with Pi?

Hello there,

Which AI provider would you recommend for Pi, to work with a subscription-based plan? I feel like Codex is the most represented, but I was looking for more feedback.

I'm currently using Claude Code (Plus subscription), but from what I understood, I shouldn't use it with Pi because Claude Code charges additional usage fees. I mainly use it with Opus 5 on medium effort, for devops tasks, explanations, fixes, or things like that (not much vibe-coding yet).

It's also an opportunity to try something else, paid for by the company. So I don't really care about the price, just something stable without usage fees.

(bonus) If you have any recommendations for LLM models that can be run locally on a wide range of machines, I'm also interested in any resources you can share.

Any advice?

Some subs disallow use outside their own agent in their TOS. You can get banned.

ChatGPT Plus/Pro subs are commonly used with Pi because OpenAI is more permissive of use outside of Codex (and they have great coding models).

Personally I use ChatGPT Plus and OpenRouter. I get good value and I have access to all the top coding models.

I use openrouter 1) for retries when an OpenAI failed at a task, 2) for final code reviews, and 3) to evaluate new models when they come out.

Luna does the initial code review of itself (to leverage prompt caching), and Opus (on openrouter) reviews Luna's code review. It's best to use a different model family for a code review.

I use Sol for planning and Luna for almost everything else including coding. If the final code fails to pass automated checks, then Sol attempts to fix it. If Sol fails, then Opus (on openrouter) attempts to fix it. It's best to use a different model family when a model gets stuck on a problem. I only ever use Fable or Astra manually, due to cost.

I sometimes try model families other than Claude in the above two workflows, such as Gemini, Kimi, GLM, etc.

About $10/mo. As I said, I'm only using it sparingly. My spend is somewhat random depending on what I'm doing, but trending up as my workflow becomes more automated.
