Description and use

**Brief Summary (2‑3 sentences)**
Krasis is a hybrid LLM runtime written in C++ that enables larger language models to run efficiently on consumer‑grade hardware with limited VRAM. By handling model partitioning, quantisation and off‑loading, it lets developers add AI capabilities without building a full model stack from scratch. The project is actively maintained (≈450 ★, recent commits) and targets rapid prototyping of RAG, agent workflows, and model‑tooling experiments.

**Value**

• **Cost‑effective scaling:** Lets teams experiment with state‑of‑the‑art models on inexpensive GPUs or even integrated graphics, avoiding pricey cloud inference.
• **Speed to market:** Provides a ready‑made runtime, so developers can focus on application logic (e.g., retrieval‑augmented generation, autonomous agents) rather than low‑level model deployment.
• **Flexibility:** Supports hybrid execution (CPU + GPU) and various quantisation strategies, making it adaptable to a wide range of hardware constraints.

**Practical Adoption Path**

1. **Proof‑of‑Concept:** Clone the repo, follow the README to build the C++ binaries on a test machine with the target GPU. Run the supplied example scripts to verify that a chosen model loads and generates.
2. **Integration Layer:** Wrap the runtime in a thin service (e.g., gRPC, FastAPI) that your application can call; this keeps the C++ core isolated while exposing a language‑agnostic API.
3. **Pilot Workflow:** Use the service in a limited internal project—such as a RAG pipeline or an AI‑assistant prototype—to evaluate latency, memory footprint, and compatibility with your existing data stores.
4. **Iterate & Optimize:** Tune quantisation, batch size, and off‑loading settings based on the pilot’s metrics; add monitoring for VRAM usage and error handling.

**Production Readiness**

• **Maturity:** Medium. The codebase is actively maintained and has a modest star count, indicating community interest, but documentation and integration guides are sparse.
• **Stability:** Suitable for internal tools, prototypes, and low‑to‑moderate traffic services after a thorough validation phase.
• **Risks:** The integration path isn’t fully documented; you’ll need to invest time in building wrappers, handling dependency management, and confirming that the runtime works with your specific model versions.
• **Next Steps for Production:** Conduct a dedicated performance benchmark, add automated tests around the wrapper service, and establish a version‑pinning strategy for the runtime and its third‑party libraries before deploying to production.

Problem

brontoguana/krasis helps add AI capability without starting from a blank model stack.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• prototype AI features
• build RAG or agent workflows
• evaluate model tooling
