## NOAN

NOAN describes itself as fact infrastructure for agentic companies. The problem it addresses is a familiar one for teams running AI agents: the price lives in fourteen system prompts, three of which are wrong; retrieval surfaces last year's deck next to this year's; memory recalls what someone said on a call rather than what was decided. NOAN's answer is to keep your company's verified facts in one place and have every agent, app, and site read them live from a single API.

Technically, NOAN exposes a plain REST API over api.getnoan.com/v1 and an MCP server at mcp.getnoan.com/mcp. You create a project, then issue a key for each agent, app, or site, scoped to the stacks it needs. A single GET returns the latest verified version of a fact block, along with who verified it and its sources. Agents can write back, posting new versions that supersede the previous ones while keeping the lineage — and if review-on-write is enabled, those writes wait for a person to approve them before anything can read them. Around that core, NOAN handles the surrounding mechanics: classification, permissions, partner sharing, and per-key activity auditing.

The platform also ships the workspace pieces agents need day to day — a shared task board for people and agents, contacts with history and open work, notes linked to facts, and reusable assets and templates. It integrates with Claude, ChatGPT, Cursor, and other MCP clients, and supports multiple model providers because the model is a configuration choice. Beyond the tooling, NOAN publishes a startup program and grant, plus material for agencies that want to run a separate fact base per client.

**Pricing & Plans:** Paid, with a free starting point: you can start free and scale when you ship, and pricing is presented as live/usage-based in the app. API access, MCP, versioned facts, review-on-write, and scoped keys are part of the platform, with higher tiers aimed at teams and agencies running the facts layer in production. A startup program and grant are also offered.

- **Verified, versioned facts:** Each fact keeps its date, sources, and the person who verified it, so nothing is silently overwritten and agents can show the receipt behind an answer.
- **Scoped keys and permissions:** Scope one key per agent, app, or site and limit it to the stacks it needs, so the right keys read the right facts and nothing else.
- **Review on write:** Turn review on for a project or a single key so any write an agent proposes waits for a human to verify it before it can be read.
- **Time Travel:** See your entire fact base as it stood on any past date, so you can answer what was true when a decision was made.
- **Activity on the record:** Every agent action lands on one timeline, marked by the key that made it, giving you auditability across agents, apps, and sites.

**Strengths:** Solves a real and specific agent problem — grounding — instead of adding another generic chatbot; Version history, sources, and named verification make outputs auditable and defensible; Model-agnostic and accessible over both REST and MCP, so it fits many stacks; Review-on-write lets agents propose updates without letting them silently change pricing or policy

**Limitations:** The product is a new category (fact infrastructure), so new users need to absorb unfamiliar concepts before they see value; Value depends on teams actually maintaining facts, so adoption requires some process discipline; Pricing is presented as dynamic and depends on the scale you ship at; It complements rather than replaces memory or RAG layers, so it is another integration to wire up

## 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
