GLM-5.3-Flash EXL3 (320B MoE) on 2x NVIDIA DGX Spark — production serving kit, 1M context, 97%+ multi-session prefix caching, DFlash2 spec decode
Validated GLM-5.3 Flash recipe for 2x NVIDIA RTX PRO 6000 Blackwell 96GB: 262K context, EXL3/TR3, adaptive MTP, tools, and vision.
A tiered-memory system design for workloads that don't fit in RAM: measure the working set, pin the hot tier, stream the cold tier from flash. Ships the residency calculator, measurement harnesses, and the build recipes behind it. Predictions validated against public benchmarks.
Serve EXL3 (ExLlamaV3 trellis) quantized models on vLLM fork runtimes — any architecture, mixed per-layer bitrates, composable with source-format non-routed weights
High-performance runtime extensions for vLLM.
Production-tuned deployment recipe: GLM-5.3-Flash 320B (EXL3 4-bit) on 2x NVIDIA DGX Spark - 850K context, DFlash2 + adaptive-k speculative decoding, full .env tuning and pitfalls
DeepSeek-V4-Flash-Vision-Exp (EXL3 MixedK, 256 experts, uncensored) on one NVIDIA DGX Spark with vLLM + sparkinfer: 245,760 context, vision + DSpark speculative decoding, CUDA graphs. Recipe, overlay patches, benchmarks, receipts.
LLM inference server for ExLlamaV3 / EXL3, with OpenAI- and Anthropic-compatible APIs optimized for Agent workloads.
LLM / AI inference server for Windows + NVIDIA (EXL3/ExLlamaV3). OpenAI-compatible API, multi-GPU, Blazor admin. Ollama-like, no Docker.
Containerized private AI lab: TabbyAPI EXL3 + SillyTavern + Open WebUI + Ollama + SearXNG
