Production-ready infrastructure, enterprise security, and developer-friendly tools.
Sub-50ms responses powered by Hardware-Direct Compilation, bypassing heavy libraries and delays.
Bank-level encryption, secure API keys, and private offline runs on local processors.
Native SDKs, interactive playgrounds, and academic partnerships (Kisii University) to build local engineering talent.
2-bit and 4-bit quantization paired with Smart Path Skipping (Sparsity) for zero-loss accuracy.
Redundant servers guarantee uptime across regional nodes and secure edge endpoints.
AWS nodes (North America, Europe, Asia) paired with a local African server node in Nakuru, Kenya.
Rax AI powers critical systems requiring sub-50ms latency, native developer SDKs, and absolute reliability.
Deploy autonomous agents that perform multi-step planning, handle complex workflows, and execute tasks reliably using Rax 4.5’s large 262K context window.
Build fast developer utilities, syntax review extensions, and automated shell command suggestions that load in milliseconds.
Create responsive, context-aware chatbot experiences that maintain chat history and answer queries with high conversational flow.
Automate repetitive workflows, parse high-volume business logs, and generate reports from databases without performance drops.
Rax AI SDK provides a simple, intuitive interface for integrating advanced AI. Start building in seconds with just a few lines of code.

Our compressed and optimized open-source model on Hugging Face. Lightning-fast and perfect for real-time applications.
Our compressed and optimized 2B parameter language model, open-sourced on Hugging Face alongside Rax 4.0. Process text with up to 262K context.
Hear from teams building production-ready products on Rax AI.
"Deploying Rax 4.0 directly to our edge clusters was incredibly simple. The latency is sub-50ms, meaning our automation pipelines run faster than ever. It's the most efficient text model we've benchmarked."
"We collect vast agricultural field reports from remote areas. Rax AI's API generates high-quality text digests instantly. Being Apache 2.0 open-source is a massive win for our global collective."
"Our user-matching system has to query high-volume databases in real-time. Rax 4.5 cut our inference response times in half, and integrating the client using the OpenAI SDK took under five lines of code."
"Rax 4.0 streaming is flawless. Chatbots on our website feel completely natural and instantaneous. Highly recommended for customer support pipelines."
"The 262K context window with optimized KV caching has completely changed how we handle server log debugging. We dump entire daily server traces in a single query, and Rax 4.5 extracts security anomalies with absolute precision."
