Ollama 0.34.1 drops LoRA adapter support
Since version 0.34.1 (September 2026), Ollama rejects any Modelfile with an ADAPTER line and no longer converts safetensors to GGUF or quantizes GGUF files. Users must now either merge the adapter into the base model and import a single GGUF, or serve it with llama.cpp's llama-server --lora.
- Version 0.40.7 from October 18, 2026 still rejects ADAPTER
- GGUF conversion and quantization moved to llama.cpp tooling
- The merged GGUF generated about 13% faster on CPU
- Older models with an adapter layer still run with a deprecation warning
