What it does
The shape of llama.cpp & Open Models, in plain English.
llama.cpp is a high-performance C/C++ inference engine for running quantized LLMs on consumer hardware, paired with models like LLaMA 3, Mistral, and Phi.
Why we like it
The parts that make us reach for it.
- Maximum performance local inference
- Edge and embedded AI
- Custom model deployment
- Research and experimentation
- Cost-free AI at any scale
When to use it
Match the tool to the job.
Each block below is a different day in the life of llama.cpp & Open Models.
coding
Ship features, refactor code, and review diffs without leaving your editor.
research
Synthesise across long PDFs, papers, and transcripts — cite as you go.
agents
Keep a loop of reasoning + tool-use that doesn't spin forever.
automation
Wire up repeatable flows without glue-code bespoke per task.
