DeepSeek-V4.1-Flash: Speed, VRAM & Benchmarks (Tested)
Real DeepSeek-V4.1-Flash benchmarks: tokens/sec speed, KV cache limits, 552B MoE architecture, VRAM usage on RTX 4090, and why V4 Pro was retired.
vLLM vs SGLang: PagedAttention vs RadixAttention Benchmarks
We benchmarked vLLM vs SGLang on multi-turn agent workloads. RadixAttention prefix caching cut TTFT by 82% over PagedAttention. Here are the benchmarks.
Fix Dual GPU Tensor Parallelism: vLLM & llama.cpp Guide
Running dual GPUs for local LLMs? Why Tensor Parallelism fails without NVLink, how to fix NCCL P2P crashes in vLLM, and how to split 70B models with llama.cpp.
Why 32k Context Crashes Local LLMs: KV Cache VRAM Fix
Why does 32k context trigger CUDA out-of-memory errors on 12GB and 16GB GPUs? Learn the exact KV cache VRAM math, Ollama config, and FP8 fixes.
Ollama vs vLLM vs LM Studio: 2026 Speed & VRAM Benchmark
Ollama, vLLM, or LM Studio? We benchmarked VRAM, TTFT latency, tokens/s, and concurrency on Windows 11 & WSL2 with RTX 4090/3080. See the empirical winner.
Cursor vs Windsurf vs Copilot: 50k-Line Codebase Benchmark
We benchmarked Cursor, Windsurf, and GitHub Copilot on a 50,000-line monorepo: multi-file refactors, autocomplete latency, RAM usage, and context retention.
Fix DeepSeek-R1 Tool Calling in Ollama & vLLM
Fix 'model deepseek-r1 does not support tools' and thinking budget desync in Ollama and vLLM. Verified Modelfile templates, API payloads, and parser fixes.
