<li><strong>Unsupervised Learning</strong>: By ramping up unsupervised learning, the model has gotten better at learning from huge amounts of data without anyone telling it what to do.</li>
</ul>



<p><strong>Applications</strong></p>



<p>ChatGPT-4.5 has many uses, which makes it a good fit for lots of different jobs such as creative writing and problem solving.
