## Overview

Cognitora is an open-source orchestration layer for distributed large language model inference, written in Rust. Rather than shipping a single inference engine, it joins the engines you already operate — vLLM, SGLang, llama.cpp, Apple MLX, a TRT-LLM spawn driver and its own preview cgn-infer engine — into one cluster behind a single OpenAI-compatible gateway. You can deploy it instead of an orchestrator such as NVIDIA Dynamo, and the project positions itself as supporting more engines, running on bare metal without Kubernetes, factoring power consumption into scheduling and avoiding a Python control plane.

Its core innovation is KV-aware routing. The router scores nodes by the longest-prefix overlap of sequence-chained BLAKE3 digests, using cache claims that agents report in heartbeats. In real llama.cpp runs the router reportedly added 0.9–2.0 ms at p50. Beyond routing, the platform splits prefill from decode across separate pools (handing KV cache off through NixlConnector), maintains a multi-tier RAM/SSD KV cache with cross-node QUIC fetch, and offers pluggable offload backends including nixl, lmcache, hicache and kvbm.

The stack is modular: cgn-router for routing, cgn-agent to supervise engines on each node, cgn-kvcached for tiered caching, cgn-metrics for Prometheus plus Redfish/NVML power telemetry, cgn-ctl as an admin CLI, an optional Kubernetes operator, and a preview native engine. Energy-aware scheduling drains hot nodes, a closed-loop autoscaler reacts to power readings, and gossip-based discovery removes the need for etcd. Security options include optional mTLS, SHA-256 checksummed releases and OIDC or scoped API-key auth. The project ships six static binaries for systemd installs, Helm charts for Kubernetes, and a single-file HTML cluster dashboard that visualises throughput, latency percentiles, KV utilisation and joules per token without Grafana.

## Pricing & Plans

Cognitora is open source and installs from its repository; there is no published per-seat or per-token price. Deployment cost is your own hardware, so total spend depends on the GPUs and nodes you run.

## Key Features & Capabilities

- **KV-aware request routing:** Routes each request to the node whose cache holds the longest matching prompt prefix, using longest-prefix overlap of BLAKE3 sequence digests to avoid repeated prefill work.
- **Engine-agnostic gateway:** One OpenAI-compatible API in front of vLLM, SGLang, llama.cpp, Apple MLX and a TRT-LLM spawn driver, so you can mix engines inside a single cluster.
- **Prefill/decode disaggregation:** Runs prefill and decode on separate replica pools with KV handoff through NixlConnector, letting each phase use hardware suited to it.
- **Energy-aware scheduling:** Folds Redfish and NVML power readings into routing scores, applies soft per-node watt caps, and drains hot nodes automatically to cut energy per token.
- **Bare metal to Kubernetes:** Deploys as six static binaries under systemd without Kubernetes, or with an optional kube-rs operator exposing InferenceCluster, ModelPool and RoutingPolicy CRDs.

## Primary Use Cases

- **Unify a mixed-engine GPU fleet (ML platform engineers):** Put a single OpenAI-compatible endpoint in front of vLLM, llama.cpp and MLX nodes so applications stop caring which engine serves a model.
- **Reduce wasted prefill compute (Infrastructure cost owners):** Use KV-aware routing and multi-tier caching to stop re-prefilling the same prompts across nodes, improving throughput on existing hardware.
- **Run inference on workstations (Edge and Apple Silicon builders):** Start on a few DGX Sparks, AMD boxes or Mac Studios with systemd and static binaries, then add QUIC federation when you outgrow one rack.
- **Cut energy per token (SRE and platform teams):** Apply power-aware admission and autoscaling so busy nodes shed traffic and the fleet runs closer to its efficiency sweet spot.

## Strengths

- Open source and self-hostable, with no per-token or per-seat licensing cost
- KV-aware routing meaningfully reduces duplicated prefill work across a fleet
- Works with many engines, so it does not lock you into one vendor's runtime
- Runs on bare metal without Kubernetes, keeping the operational surface small

## Limitations

- Requires substantial LLM infrastructure knowledge and hands-on GPU hardware to evaluate
- Several headline capabilities are on the main branch but not yet in a tagged release
- TRT-LLM support is a spawn driver only, without a default recipe or CI GPU test

## Frequently Asked Questions

### Is Cognitora a model hosting service?
No. It is an orchestration layer you deploy on your own hardware or Kubernetes cluster. It supervises and routes to inference engines rather than selling hosted API access.

### Which inference engines does it support?
It works with any engine exposing an OpenAI HTTP API, and ships drivers for vLLM, SGLang, llama.cpp, Apple MLX and trtllm-serve, plus a preview first-party engine called cgn-infer.

### Do I need Kubernetes to run it?
No. Bare-metal installs use six static binaries under systemd. A Kubernetes operator with CRDs is optional and only needed for declarative rollouts.

### What makes the routing different?
The router picks nodes by longest-prefix overlap of prompt caches, so repeated prompts hit nodes that already hold their context instead of forcing a fresh prefill.

### What is Cognitora's monthly traffic and growth trend?
Cognitora currently receives 0 monthly visits, with a month-over-month traffic change of +0 (0.0% growth rate). Its primary source market is Global (— share), including 0 direct visits/mo and — organic search visits/mo.

### Is Cognitora free? What is its pricing model?
Cognitora operates on a Open Source pricing model. Cognitora is open source and installs from its repository; there is no published per-seat or per-token price. Deployment cost is your own hardware, so total spend depends on the GPUs and nodes you run. Supported billing and checkout platforms include: not listed.
