Dual GPU Sanity Check: Is This a Smart Buy?

A user asks whether adding a GTX 5060 Ti 16GB to their existing RTX 5090 setup is worth it for better VRAM to run larger LLMs and extend ComfyUI video generation. The upgrade would allow using Qwen 3.6 with 256K context and improve 1440p video generation, though performance gains in ComfyUI are limited due to current software constraints.

Concept-Constrained Prompt Learning for Few-Shot CLIP Adaptation

CCPL introduces a lightweight framework that anchors class prompts to frozen concept prototypes, improving few-shot CLIP adaptation. It achieves better base-to-new performance on DTD and EuroSAT compared to CoOp, with consistent gains from text-space concept regularization, while maintaining neutrality on OxfordPets. The method uses concept dropout and controllable ensemble fusion at inference, with results sensitive to dataset semantics and protocol.

Context-Aware Distillation and Ablation for Text2DSL

A new Text2DSL system uses context-aware distillation with a structured context of BNF grammar, API specification, and closed identifier vocabulary. Ablation studies show that the vocabulary has the largest impact on semantic quality, while API and BNF significantly improve structural validity, confirming structured context as a critical, load-bearing component.

CWE-Level Generalisation in Syscall-Based HIDS

A one-class anomaly detector trained on normal behavior of CVEs sharing a CWE class can generalise to unseen CVEs within the same class, but effectiveness varies by CWE family. The CWE-307 detector achieves F1 = 0.6976 at 5% false positive rate, while CWE-89 and CWE-434 perform poorly, with F1 ≤ 0.21. Cross-CVE transfer is direction-dependent and driven more by the breadth of the source normal profile than the CWE category.

Importance-Weighted On-Policy Distillation Addresses Position Bias

On-Policy Distillation (OPD) suffers from position bias where later tokens provide poor supervision. Importance-Weighted OPD (IW-OPD) assigns dynamic weights based on distribution discrepancy, prioritizing early tokens and suppressing late ones. IW-OPD converges faster and achieves up to 6.9 point performance gains on AIME-2025 compared to standard OPD.

Qwen3.6 27B more dumb in vLLM compared to llama.cpp

A user reports that Qwen3.6-27B runs significantly less intelligently in vLLM than in llama.cpp, exhibiting issues like ignoring messages, hallucinating tool calls, and failing to recognize prior conversation context. Despite proper configuration and prompt templates, the model appears to lose coherence and misinterprets its own tool usage, with errors occurring consistently rather than sporadically.
