Model weight loading for the Flash-MoE inference engine.

Ensuring correct file path resolution and loading of model weights (`model_weights.bin`) for the Flash-MoE engine, particularly when models are sourced from Hugging Face caches.
The Flash-MoE inference engine fails to load `model_weights.bin` due to a 'No such file or directory' error, despite correctly identifying the Hugging Face cache path for the model. This indicates a common deployment and packaging issue: the inference engine expects the weight file in a specific ...

TurboQuant (turbo3/turbo4 cache types) for LLM inference, specifically its compatibility with new NVIDIA Blackwell GPUs.

Achieving reliable, performant LLM inference on cutting-edge GPU architectures (NVIDIA Blackwell, compute capability 12.0) using optimized quantization schemes.
This issue exposes a critical compatibility gap for TurboQuant's CUDA kernels on NVIDIA's new Blackwell architecture (sm_120). The failure to produce coherent output with `turbo3`/`turbo4` cache types, while `q8_0` functions correctly, indicates a fundamental problem with dequantization kernels o...

TurboQuant (turbo3 and turbo4) performance optimization for LLM inference, specifically on Apple M1 hardware.

Achieving superior LLM inference speed (tokens/sec) through TurboQuant optimizations on Apple Silicon (M1).
This issue reports a critical failure in TurboQuant's core value proposition: performance improvement. On Apple M1 hardware, `turbo3` and `turbo4` not only fail to increase `tokens/sec` but actually degrade performance compared to the baseline `llama-cpp`. This directly undermines the market viab...

TurboQuant (`-ctk turbo3 -ctv turbo3`) integration with Vulkan devices for LLM inference.

Achieving broad hardware compatibility for TurboQuant, specifically extending to Vulkan-enabled AMD GPUs.
This issue reports a critical failure of TurboQuant on Vulkan-enabled AMD GPUs, specifically with `turbo3` cache types. The execution halts during model loading, indicating a fundamental incompatibility or bug within the `ggml-backend.cpp` Vulkan implementation. For B2B SaaS, limited hardware com...

`AttnRes` (Attention-Residuals) framework, specifically its limitations in handling 'attention saturation' and 'phase transitions' during 'long-horizon human–AI interactions.'

Enhancing `AttnRes` to manage complex, extended human-AI interactions by introducing dynamic attention modulation and supervisory interventions.
This detailed proposal identifies critical limitations in `AttnRes` for 'long-horizon human–AI interactions,' specifically 'attention saturation' and 'phase transitions.' Empirical evidence from a 180-day trace reveals 'non-linear phase dynamics' not captured by current fixed inference mechanisms...

`Flash-MoE` for running large MoE models (Qwen3.5-397B-A17B) locally on Apple Silicon Macs.

Enabling local, cloud-independent execution of massive MoE models on consumer-grade high-end hardware (Apple Silicon), achieving interactive performance.
This issue provides a critical 'gotcha' guide for `Flash-MoE`, highlighting the significant setup complexity for running massive MoE models locally on Apple Silicon. The primary pain point is the exorbitant temporary disk space requirement (~450GB) and the need for high-end unified memory (48GB+)...

TurboQuant's quantization strategy, specifically regarding K/V norm disparity, attention quantization methods (MSE vs. Prod), and outlier detection (dynamic vs. fixed).

Advancing TurboQuant's quantization efficacy to achieve lower perplexity (PPL) and higher compression (lower average bit rates) through refined techniques.
This issue presents critical engineering findings for TurboQuant, revealing significant opportunities for optimization. The 'K/V norm disparity' necessitates mixed precision, as uniform quantization catastrophically fails for models like Qwen with high K/V ratios. Furthermore, MSE is empirically ...

`turbo3` decode performance for LLM inference on Apple Silicon (M1, M2 Pro, M5 Max), specifically addressing the 'decode cliff' at increasing context depths.

Achieving flat, high-performance `turbo3` decode ratios (0.90x+ of `q8_0`) across all context depths on Apple Silicon, minimizing performance degradation from memory access patterns.
This extensive analysis identifies a critical performance bottleneck for `turbo3` decode on Apple Silicon: a 'decode cliff' at increasing context depths, particularly severe on M1/M2, initially attributed to centroid LUT constant memory accesses. Profiling reveals the constant memory LUT is indee...
