## Cognitora

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.

- **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.

**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

## FlexAI

FlexAI sits one layer above both model APIs and raw GPU clouds. Instead of stopping at a single inference call or a bare compute rental, it offers a managed path from the first API key to fully private AI infrastructure. Token Factory serves 30+ open models — text, code, vision, embeddings, image, speech and video — behind one OpenAI-compatible endpoint, so most applications migrate simply by changing a base URL. AgentOS adds an agent runtime connected to company context and tools, with scoped memory, approvals and an audit trail.

For teams that outgrow shared endpoints, FlexAI offers Dedicated GPUs for VMs, fine-tuning and production inference on FlexAI-operated NVIDIA, AMD and Tenstorrent fleets, plus AI Factory for VPC, on-premises and air-gapped deployments. The platform emphasises zero data retention: prompts and outputs are not stored and never train any model, alongside SOC 2 Type II and GDPR alignment and an EU data option.

Pricing is transparent and usage-based on the serverless lane — per token for text, and per image, per million characters of speech, per minute of audio or per minute of generated video for media models — while dedicated capacity and private deployments are quoted per engagement. A startup program offers credits and discounts on dedicated capacity.

**Pricing & Plans:** Pay-as-you-go serverless pricing (per token for text; per image, audio or video minute for media) with a free playground, plus dedicated GPU and private-cloud plans quoted on request. Startup credits and discounts available.

- **OpenAI-compatible model API:** One API key and a drop-in OpenAI SDK replacement unlock 30+ open models across text, reasoning, coding, vision, embeddings, speech-to-text, text-to-speech, image and video.
- **AgentOS agent runtime:** Run agents connected to company context and tools with scoped memory, tool permissions, human approvals and an auditable decision trail.
- **Dedicated GPUs and fine-tuning:** Reserve NVIDIA, AMD or Tenstorrent capacity for VMs, fine-tuning and production inference when shared serverless endpoints are not enough.
- **Private and sovereign deployment:** AI Factory supports VPC, on-premises and air-gapped installs, with zero data retention, an EU option, SOC 2 Type II and GDPR alignment.
- **No-signup playground:** Try image generation and chat completions directly in the browser before creating an account, on the same API you would use in production.

**Strengths:** Single OpenAI-compatible endpoint across text, vision, code, embeddings, speech, image and video models; Clear path from serverless inference to dedicated GPUs to private or air-gapped clouds; Zero data retention by default with SOC 2 Type II, GDPR alignment and an EU option; Governed agent runtime with approvals, audit trails and scoped memory

**Limitations:** Serverless rates are repriced against the market, so budgets need periodic review; Dedicated and private deployment pricing is quote-based rather than published; The broad catalogue means teams still need to benchmark model quality for their own tasks
