dev      -> claude : Runs "claude --model gpt-oss:20b"
claude   -> fs     : Scans repository context
fs      --> claude : File contents / Git history

claude   -> ollama : POST /v1/messages (Anthropic API)
note right: Payload includes system prompt \nand local code context

ollama   -> model  : Load weights into GPU VRAM
model   --> ollama : Inference processing...

ollama -->> claude : Streamed Response (Tokens)
claude   -> dev    : Displays suggested code changes

Optimization

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
