Full attention scales quadratically with sequence length, while state space models (SSMs) are linear but recall specific details poorly. The authors propose Samba, a hybrid that stacks Mamba layers, SwiGLU MLPs and Sliding Window Attention (SWA, window 2048) in… 2. **[AgentInstruct: Toward Generative Teaching with Agentic Flows](https://md.research.elamur.ai/free/en/papers/mitra-2024-agentinstruct-toward-generative-teaching-agentic/)** *(2024 · 42 citations)* Post-training language models on synthetic data is appealing, but such data often lacks quality and variety. 3. **[Efficient RLHF: Reducing the Memory Usage of PPO](https://md.research.elamur.ai/free/en/papers/santacroce-2023-efficient-rlhf-reducing-memory-usage/)** *(2023 · 20 citations)* RLHF with PPO is costly. The PPO stage keeps an actor, a critic, a frozen reference policy and a frozen reward model in memory at once, so it needs more than three times the memory of supervised fine-tuning. That puts it out of reach for many teams. The Microsoft authors measure how several memory-saving variants… ## All works 4 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1.
