<p dir="auto">it looks like <span class="glossary-wrapper" title="artificial intelligence" data-bs-toggle="tooltip" data-bs-placement="top"><span class="glossary-word">AI</span></span> world is moving quite fast…</p>
<p dir="auto">And recently I read that Claude Mythos , which is only available to a bunch of tech giants, finds bugs/security vulnerabilities of the applications very efficiently, and since Anthropic thinks it is very advanced and can be mis-used, first they wanted to make this available to big companies, so they can fix all possible vulnerabilities of their applications.</p>
<p dir="auto">I just updated Firefox to version 150, and Mozilla says they fixed 271 bugs thanks to Claude Mythos in this version.</p>

<p dir="auto">I cannot really tell if these were real serious bugs or just small fixes, but it looks like it is helping companies, although I am not very comfortable that these companies are selected (based on what?) and given advantage. I like Mozilla and Firefox and support them forever <img src="https://sudonix.org/assets/plugins/nodebb-plugin-emoji/emoji/android/1f604.png?v=d3ec1f462c0" class="not-responsive emoji emoji-android emoji--smile" style="height:23px;width:auto;vertical-align:middle" title=":D" alt="😄" /></p>

<p dir="auto">Since it is also close to what you professionally do (at least to my perspective <img src="https://sudonix.org/assets/plugins/nodebb-plugin-emoji/emoji/android/1f604.png?v=d3ec1f462c0" class="not-responsive emoji emoji-android emoji--smile" style="height:23px;width:auto;vertical-align:middle" title=":D" alt="😄" /> since I am working in biomedical field), I was curious if you have tried any of these <span class="glossary-wrapper" title="artificial intelligence" data-bs-toggle="tooltip" data-bs-placement="top"><span class="glossary-word">AI</span></span> tools in your work. And if it is easy for small teams such as NodeBB to try these and find vulnerabilities in the NodeBB infrastructure.</p>
