Any improvement to the ChatGPT free plan is really nice. It's easy to forget that most people have never used a SOTA model, and only think of their experience with GPT-4o or Google Search's AI Overviews when asked about AI.

It's also pretty cheap if you're paying for it (for coding). But I don't quite trust it for anything complicated, so I often use Terra.

Terra is awful and not cheap enough to make up for it. I'd suggest using luna or sol.

Terra is far from awful. I've not used Luna enough to judge whether it's significantly better than Luna, but at least via GitHub Copilot, Terra is leaps ahead of Sonnet 5.

It's not awful, but if you are doing research or anything complex and don't want to spend hours fighting it, Sol is not an option.

Luna is not bad, but... you feel is a small model. It have less knowledge. It's ok for purely agentic stuff (web searching etc).

So Luna is more awful but it's OK because it's cheaper?

I've had great success with using Luna and having DeepSeek 4 Flash check Luna's output. Oh My Pi has a mode built-in that does this automatically ("advisor" mode). Deepseek only interrupts when it spots an issue so it doesn't slow Luna down.

Both models are cheap enough that I can run 4 sessions at the same time without running out of the 20 USD codex and 10 USD Opencode plan. I've burned through almost a billion tokens this week and I've done some pretty big refactors as well.

I have a Claude Max subscription but I've barely been using it because of the many issues they've had this week.

Yes, in the same way a basic, dry hotdog at $5 is bad, but I could love it in $0.50.

Pricing absolutely matters.

Indeed.

I buy 2 hot dogs for $1 at Sheetz sometimes. For that price, I get them with mustard, onions, and sauerkraut already on them.

They are not excellent in any way. I will probably never love them. :)

But they're available 24/7/365 and they don't take long for the staff to throw together.

And most importantly: They sure are cheap.

(Costco's $1.50 dog+Coke is much higher quality and presents a better value, but it requires visiting a Costco and that has its own cost.)

Yes. You're better off running Luna Max or Sol Medium and never touching Terra.

I guess I should give it another shot because I had pretty bad experience with Luna when it first came out. Stuff Sonnet knew better.

Luna correlates with Claude Haiku, not sonnet. I think Terra would be the equivalent to Sonnet.

Were free users subject to some limits? I've never run into any limits.

It used to be 10 messages every 5 hours using GPT-5, then unlimited 4o-mini. More recently, it went down to ~5 messages per day on 5.5 Instant, then unlimited on 5.5 mini.
