I tracked my real usage for 3 months. The $20/mo Pro plan covers about 200-300 messages per day with Sonnet 4.5. Heavy coding days I hit the cap. If you use it casually, the $20 is enough. If you use it 8 hours daily, expect to pay for the higher tier or ration usage.
By default, free and Pro tier conversations are used for training. You can opt out in settings (Data Controls → Help improve ). I have it disabled on all my accounts. Enterprise tier has training disabled by default.
has a 200K token context window (about 500K words). My medium-sized saas.pet codebase fits in 3 contexts. For larger codebases, use the Projects feature to upload specific files. For megarepos (1M+ lines), you will hit limits and need Claude Code instead.
For long-form reasoning and code review, yes — Claude is better. For quick edits, multimodal input (image+text), and ecosystem, ChatGPT is better. I use both: ChatGPT for vision and quick tasks, for deep coding work. The $40/mo combined is worth it for me.
I've been testing and reviewing AI tools for 2+ years. I run saas.pet as a side project while working as a software engineer. I buy every subscription I review. No vendor pitches, no free accounts. If a tool is in my rotation, I pay for it.
