Hyper-Connections (HC) try to push this idea further by widening the residual stream into multiple parallel “streams” and learning how to mix them, so the model can exchange information across depth without increasing the core layer FLOPs much. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="dd" align="left" style="padding:0px 28px;text-align:left;word-break:break-word;"&gt;&lt;p style="mso-line-height-alt:150.0%;"&gt; The problem is that the more freedom HC gives those cross-stream mixing matrices, the less it behaves like an identity path. When you stack many layers, the product of these unconstrained residual mixing matrices can amplify or shrink signals unpredictably, which shows up as training instability in large runs. In their 27B setup, the paper reports a loss surge for HC around 12k steps and extremely large composite “gain magnitudes” that can peak around 3000, a sign of exploding residual dynamics. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="dd" align="left" style="padding:0px 28px;text-align:left;word-break:break-word;"&gt;&lt;p style="mso-line-height-alt:150.0%;"&gt; Their fix is &lt;b&gt;Manifold-Constrained Hyper-Connections (mHC)&lt;/b&gt;. Instead of letting the residual mixing matrix be anything, they project it onto the manifold of doubly stochastic matrices, meaning all entries are non-negative and every row and column sums to 1. That keeps the residual pathway closer to a stable identity-like behavior while still allowing streams to mix, since each stream becomes a convex combination of the others rather than an arbitrary linear remapping. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="padding-bottom:20px;padding-left:15px;padding-right:15px;padding-top:20px; " class="dd"&gt;&lt;table role="none" border="0" cellspacing="0" cellpadding="0" style="margin:0 auto 0 auto;"&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="width:626px;"&gt;&lt;img src="https://media.beehiiv.com/cdn-cgi/image/fit=scale-down,format=auto,onerror=redirect,quality=80/uploads/asset/file/68e2e976-8c5b-41ea-be3a-eb1fdde71892/CleanShot_2026-01-06_at_18.59.11_2x.png?t=1767706172" alt="" height="auto" width="626" style="display:block;width:100%;" border="0"/&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" class="t" style="width:626px; padding: 4px 0px 4px 0px;"&gt;&lt;p&gt;Illustrations of Residual Connection Paradigms.&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="dd" align="left" style="padding:0px 28px;text-align:left;word-break:break-word;"&gt;&lt;p style="mso-line-height-alt:150.0%;"&gt; Practically, they build this projection with the Sinkhorn-Knopp algorithm, running a limited number of iterations (they use 20) to turn an unconstrained matrix into an approximately doubly stochastic one.

However, is this tool that everyone uses actually the best one for this specific type of learning, or are we leaving performance on the table by ignoring better alternatives? &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="padding-bottom:20px;padding-left:15px;padding-right:15px;padding-top:20px; " class="dd"&gt;&lt;table role="none" border="0" cellspacing="0" cellpadding="0" style="margin:0 auto 0 auto;"&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="width:626px;"&gt;&lt;img src="https://media.beehiiv.com/cdn-cgi/image/fit=scale-down,format=auto,onerror=redirect,quality=80/uploads/asset/file/64fac71e-fa13-4e03-91e6-eeb2a226f193/CleanShot_2026-01-06_at_19.22.43_2x.png?t=1767707583" alt="" height="auto" width="626" style="display:block;width:100%;" border="0"/&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="dd" align="left" style="padding:0px 28px;text-align:left;word-break:break-word;"&gt;&lt;p style="mso-line-height-alt:150.0%;"&gt; The team discovered that the industry standard is suboptimal for reinforcement learning. By testing over a dozen different efficiency methods, they found that newer &quot;structural&quot; variants (approaches that change how weight updates are structured rather than just adding a simple adapter) consistently outperformed the default method. In some cases, these structural variants even surpassed the performance of full-parameter training, which is typically considered the gold standard. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="padding-bottom:20px;padding-left:15px;padding-right:15px;padding-top:20px; " class="dd"&gt;&lt;table role="none" border="0" cellspacing="0" cellpadding="0" style="margin:0 auto 0 auto;"&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="width:626px;"&gt;&lt;img src="https://media.beehiiv.com/cdn-cgi/image/fit=scale-down,format=auto,onerror=redirect,quality=80/uploads/asset/file/0384ea49-6284-4356-bda5-0902d01b2b1e/CleanShot_2026-01-06_at_19.23.12_2x.png?t=1767707604" alt="" height="auto" width="626" style="display:block;width:100%;" border="0"/&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" class="t" style="width:626px; padding: 4px 0px 4px 0px;"&gt;&lt;p&gt;A variety of PEFT methods are listed, each with its specific update formulation and initialization strategy.

Some advanced methods try to initialize training by focusing on the model&#39;s &quot;loudest&quot; or most significant existing features. The researchers found this causes the training to collapse because reinforcement learning actually thrives by tweaking the quieter, less dominant parts of the network. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="dd" align="left" style="padding:0px 28px;text-align:left;word-break:break-word;"&gt;&lt;p style="mso-line-height-alt:150.0%;"&gt; Additionally, the team identified a strict limit to efficiency. While it is possible to freeze large portions of a model, attempting extreme compression bottlenecks the system. To learn complex reasoning, the model retains a need for a minimum amount of &quot;plasticity,&quot; or trainable parameters, without which its ability to evolve stalls completely. &lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td align="center" valign="top" style="padding-bottom:20px;padding-left:15px;padding-right:15px;padding-top:20px;
