Free memory matters before model size
The first condition for running locally is the actual free memory, not the model name. Quantization level and context length also use memory, so it is safer to start with a small model and short requests and then scale up.
Separate the roles of Studio and the runtime
Unsloth provides tools for local inference and training, and Studio is an option for browsing, running, and configuring models from a UI. Specific DeepSeek releases and performance multipliers can change, so right before installing, check the official supported list and release notes again.
Decide the access scope before opening the local API
Even with a local model, opening an API port lets other processes reach it. Start personal-device testing within localhost, and add authentication and network policy only when an external connection is needed.
