Optimization

Variable Value Impact OLLAMA_FLASH_ATTENTION 1 Reduces memory usage and speeds up processing for long code files. Highly recommended for coding. OLLAMA_KV_CACHE_TYPE q8_0 or q4_0 Compresses the short-term memory cache. q8_0 saves space with almost no quality loss; q4_0 saves even more space. OLLAMA_NUM_PARALLEL 1 Crucial for 32GB RAM. Limits Ollama to one task at a time to prevent Out of Memory crashes when using a 20B model. OLLAMA_KEEP_ALIVE 30m Keeps the 20B model in your RAM for 30 minutes after use so you don't have to wait 20 seconds for it to reload every time. OLLAMA_NUM_CTX 6384 to 32768 The most important. Controls the brain capacity. 32k is standard for Claude Code but uses ~3GB more RAM than the default 4k. OLLAMA_NUM_GPU 999 Forces Ollama to offload as many layers as possible to your Intel Arc iGPU instead of the slower CPU. OLLAMA_NUM_GPU 0 Forces Ollama CPU-only for all models CUDA_VISIBLE_DEVICES -1 Hides any GPU from the Ollama process ROCR_VISIBLE_DEVICES -1 Hides any GPU from the Ollama process OLLAMA_INTEL_GPU 1 Forces Ollama to use Intel Arc GPU
