## 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

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
