**Typed relationship:** llama.cpp _(alternative)_ optimate

OptiMate and llama.cpp both focus on optimizing LLMs, but they use different programming languages (Python vs C/C++).

## Decision facts: llama.cpp

- **Requirements:** - No external dependencies required for C/C++ implementation.; - Custom CUDA kernels support running LLM on NVIDIA GPUs.
- **Adopt for:** A C/C++ library for performing large language model (LLM) inference with minimal setup, enabling state-of-the-art performance across various hardware architectures.

## Decision facts: optimate

- **Adopt for:** OptiMate is a collection of open-source libraries in Python designed to optimize the performance and resource utilization of AI models, though it now operates in a legacy phase meaning no further updates or official code

## Choose when

### Choose llama.cpp if…

- llama.cpp is primarily C++; optimate is Python.
- License: llama.cpp is MIT, optimate is Apache-2.0.
- Requirements: - No external dependencies required for C/C++ implementation.; - Custom CUDA kernels support running LLM on NVIDIA GPUs..
- OptiMate and llama.cpp both focus on optimizing LLMs, but they use different programming languages (Python vs C/C++).
- Tags unique to llama.cpp: rest api, hugging-face, c++, llm-inference.
- When you require a lightweight and dependency-free solution for LLM inference that supports multiple hardware architectures including x86, ARM, and RISC-V.

### Choose optimate if…

- optimate is primarily Python; llama.cpp is C++.
- License: optimate is Apache-2.0, llama.cpp is MIT.
- OptiMate and llama.cpp both focus on optimizing LLMs, but they use different programming languages (Python vs C/C++).
- Tags unique to optimate: llm, ai, artificial-intelligence, large-language-models.
- Also covers Evaluation & Observability, Model Training.
- When you need optimization techniques for enhancing inference costs by leveraging state-of-the-art approaches that couple your AI models with hardware like GPUs and CPUs through tools such as Speedスター

## When NOT to use llama.cpp

- If you are working in an ecosystem requiring heavy use of high-level languages such as Python or Java, given `llama.cpp`'s focus on C/C++ and low-level optimizations.
- When developing applications that need frequent API changes, as the updates in `libllama` and `llama-server` REST API might not align with your application’s release cycle.

## When NOT to use optimate

- Do not use OptiMate if you need ongoing support or active development. The project has moved into a legacy phase and receives no further updates
- Avoid using OptiMate for future AI deployment if you are aiming to integrate state-of-the-art real-time observability features as it's no longer actively maintained nor receiving new improvements
