@AI Advantage Team Thanks Laure. As you have realised, I am trying to keep my subscription costs down, and not knowing which one is best for what is a real dilemma. Also, ChatGPT has begun to lag, especially with long chats, and causing other chats to load more slowly. I have noticed that Claude compresses long chats. I am leaning towards subscribing to Monica, so I can test the other AIs and see how ChatGPT and Claude perform with Monica. Thanks for the advice. Stirling.

@Phebe J Hi Phebe, I mainly use the AIs (ChatGPT, Claude, and sometimes Google's Gemini AI) inside a browser. You have made a great point on the underlying models Monica uses and the full features. I've just had a quick look at the underlying models Monica uses with subscription. For ChatGPT and Claude, it seems they are not using the latest modes. At this moment, writing and research. I am interested in AI automation and agents. At the moment, I don't know where I can use AI automation. As I am still learning about AI. [Notes (updated): ChatGPT is currently 5.3 or 5.4-Thinking (paid plan). I am not sure if 5.4-Thinking is available with the free plan, but if I remember correctly, there's limited usage with the higher model on the free plan. With Claude's free plan, you can use Sonnet 4.6 and Haiku 4.5 (with limited usage). Upgrading the plan on Claude unlocks Opus 4.6, 4.5, and 3 - Thinking models (and gives more usage). Claude Haiku 4.5 is also available in Monica for free. Monica paid plans use Claude 4.5 Sonnet. Monica's free plan includes GPT-4o mini, GPT-4.1 mini, GPT-4.1 nano, and Claude Haiku 4.5 (as well as other basic models). Paid plans provide more advanced models with limited usage (depending on plans). These include GPT5.4 (Pro and normal), 5.3 (codex and normal), 5.2, 5.1, and 5. Claude's 4.6 Sonnet & Opus, 4.5 Opus, 4 Sonnet & Opus, 4.1 & 4 Opus-Thinking, and 4 & 3.7 Sonnet-Thinking. As well as more advanced models. ]

@Igor Pogany Thank you. I haven't tried Claude, yet. I have been a little concerned about how to migrate (or clone memories) to other LLMs. Perhaps, other LLMs will introduce this feature as well.
