We start with the first of three lines on language model safety.</p> <h2 id="the-question">The question <a class="hanchor" href="#the-question" aria-label="Enlace a esta sección">#</a></h2> <p>Fine-tuning a language model so that it refuses harmful requests has a cost: if it is taught too thoroughly to say no, it starts refusing harmless things too, and loses usefulness. The line studies that balance: <strong>what proportion of safety data has to be mixed with the utility data, and whether the model itself can generate its own refusal examples and regulate the dose on its own.</strong></p>https://ants.inf.um.es/gaialab/blog/en/posts/que-corre-de-verdad-en-nuestro-cluster/Tue, 22 Sep 2026 10:00:00 +0200https://ants.inf.um.es/gaialab/blog/en/posts/que-corre-de-verdad-en-nuestro-cluster/<p>A cluster&rsquo;s job history is usually a wall of six-digit identifiers and cryptic names —<code>mcpfw_cc</code>, <code>eval_dynamic_pid</code>, <code>boltz2</code>— that say everything to whoever launched them and nothing to anyone else. But if you keep the <em>scripts</em>, the wall turns into a document: people write down <strong>why</strong> they do things, especially when a batch costs money and a night of waiting.</p>
