1. **[Intention Analysis Makes LLMs A Good Jailbreak Defender](https://md.research.elamur.ai/free/en/papers/zhang-2025-intention-analysis-makes-llms-good/)** *(2025 · 21 citations)* Safety-aligned LLMs can still be broken by jailbreaks, which hide a harmful request inside elaborate role-play or fictional framings.
2. **[SpindleKV: A Novel KV Cache Reduction Method Balancing Both Shallow and Deep Layers](https://md.research.elamur.ai/free/en/papers/tang-2025-spindlekv-novel-kv-cache-reduction/)** *(2025 · 9 citations)* Long-context inference with LLMs is limited by the GPU memory consumed by the KV cache. Earlier token eviction, merging and quantization methods compress deep layers well, but shallow layers resist them. In a preliminary analysis of LLaMA2-7B-chat on 2WikiMQA, the authors found two patterns. Deep layers concentrate…
3. **[KV-Latent: Dimensional-level KV Cache Reduction with Frequency-aware Rotary Positional Embedding](https://md.research.elamur.ai/free/en/papers/luohe-2025-kv-latent-dimensional-level-kv/)** *(2025 · 6 citations)* Decoder-only LLMs store keys and values for every generated token. This KV Cache grows with sequence length and becomes a major limit on memory and bandwidth during inference. KV-Latent tackles this at the level of individual head dimensions, a direction earlier head-, layer- and token-level methods have left largely…
4. **[RACER: Retrieval-Augmented Contextual Rapid Speculative Decoding](https://md.research.elamur.ai/free/en/papers/zhang-2026-racer-retrieval-augmented-contextual-rapid/)** *(2026 · 1 citation)* Large language models decode one token at a time, which makes inference slow. Speculative decoding speeds this up by drafting several tokens and checking them in parallel with the target model. Training-free variants have two weaknesses. Retrieval-based drafters fail when the context contains no exact match.…
5. **[From AR to Diffusion: Efficiently Adapting Large Language Models with Strictly Causal and Elastic Horizons](https://md.research.elamur.ai/free/en/papers/ma-2026-ar-diffusion-efficiently-adapting-large/)** *(2026)* Diffusion language models can produce several tokens at once. However, they usually depend on bidirectional attention, which conflicts with how pre-trained autoregressive (AR) models such as GPT-style LLMs are built. Because of this, they are often trained from scratch at great cost. Existing block diffusion methods…
