MiniToolAI Reviews 

Hi team, thank you for building minitoolAI. I've been enjoying the platform, especially the unlimited access to GPT-6 Astra, which has been very helpful for my daily work.

I wanted to share a small suggestion. In my workflow I often switch between models depending on the task:

Claude Fable 5.1 for long-context codebase reviews (1M context, efficient cache)
Gemini 4 Argon for research and multimodal tasks
Kimi K3 for very long documents and repository-level analysis
Currently Fable 5.1 is only available as a paid option, so I need to use another platform when I need those specific strengths. If you ever consider expanding the free tier to include Fable 5.1 alongside Astra, and perhaps Argon and K3 in the future, I think many users like me would be able to stay entirely within minitoolAI.

Thanks again for the great work you are doing. Keep it up!

It's a massive red flag when freemium web utilities like MiniToolAI offer flagship AI models like Opus 4.8 and GPT 5.6 Terra completely for free and without usage caps. These models are extraordinarily expensive to run, no legit business model can afford to give millions of users "unlimited, free" access.

What MiniToolAI probably does is use a bait-and-switch tactic. When you click on "Opus 4.8" or another flagship AI, their backend routes your prompt to a cheap, tiny open-source model backend. It's just a cheap substitute under a luxury label.

Think: If high-end frontier models like Opus, GPT-5.6, and Grok were cheap enough to hand out for free and without limits, tech giants backed by billions of dollars would gladly do it to wipe out competitors. Even on OpenAI's budget-tier Luna (which is cheap at $0.20/$1.20), heavy continuous usage across thousands of users adds up to massive server bills. Multiply that by flagship models like Opus 4.8 where generating output tokens costs up to $30.00 per million, and it becomes completely impossible for an unverified, ad-supported web tool to hand out unlimited access for $0 without losing thousands of dollars a day.

It's just too good to be true.

Please provide the option to play from a custom position with ChessGPT. I am requesting this option because the page sometimes crashes and I have to start a new game. Thanks!
