What you get on the free tier

Most free AI assistant tiers include unlimited use of a smaller model (Claude Haiku, GPT-4o-mini, Gemini Flash) plus a daily quota of the flagship model. Real-world this is enough for 30-50 typical chat sessions per day, which covers most professional use.

When it is worth upgrading

Upgrade when you hit the daily flagship-model quota multiple times per week, when you need extended thinking modes for hard reasoning tasks, or when you need data-not-trained-on guarantees for confidential work.
