Cognitora features
- KV-Aware Routing. BLAKE3 sequence digests route requests to nodes with cached prefixes, reducing redundant prefill work.
- Energy-Aware Scheduling. Power telemetry (Redfish, NVML) influences routing scores and enforces soft watt caps.
- Multi-Tier KV Cache. RAM (DashMap) and SSD (RocksDB) tiers with cross-node QUIC fetch accelerate token reuse.
- Engine-Agnostic Agent. Supervises vLLM, SGLang, llama.cpp, MLX, TRT-LLM and OpenAI-compatible servers via a single OpenAI gateway.
- Bare-Metal First Deploy. One curl install, six static binaries and systemd units run without Kubernetes.
- Cross-Cluster Federation. Routers forward requests to the lowest-latency peer cluster when local nodes lack the model.
- Native Inference Engine. First-party GGUF engine on Candle runs models directly behind the same OpenAI HTTP surface.
- Observability Dashboard. Zero-dependency web UI shows live request, token, latency, KV utilization and power metrics.
LangChain features
- Build agents fast. Start with proven patterns, customize harness, context, memory and model choice.
- Trace-based testing. Debug runs with step-by-step tracing and query complex traces instantly.
- Managed deployments. Deploy long-running agents with serverless or dedicated sandboxes and 30+ endpoints.
- Production monitoring. Online evals, dashboards and alerts track quality, cost, latency and errors.
- Feedback loop engine. Automatically detect issues, diagnose root causes and feed fixes back into evals.
- Governance controls. Enforce cost limits, data redaction and human approval via LLM Gateway.
