## Momen

Momen positions itself as the missing backend layer for no-code and AI-assisted app building. Instead of stitching together a database service, an automation engine and a design tool, Momen bundles them: a visual agent builder for LLM-powered logic, a structured database with typed schemas, Actionflows for trigger- and schedule-driven automation, and a built-in user system with authentication. The company describes the combination as roughly n8n plus Supabase plus Framer in one workspace.

On the AI side, agents can be wired to pre-integrated models or your own model, spanning OpenAI, Gemini, Claude, Grok, Qwen, Cohere and others. Agents ground their answers in live business data pulled from your database or connected APIs, take action through toolkits that call APIs or run Actionflows, collaborate with other agents, and return typed JSON so results can write straight back into your data layer. Momen also publishes a generator that turns a prompt into a working UI in tools such as Lovable or Cursor, which you then connect to the Momen backend.

Momen is a venture-backed company with backing from Sequoia, MiraclePlus and Linear Capital, and it hosts and operates from the United States. Pricing starts free for building and exploring, with paid tiers billed per project per month that raise resource limits, unlock custom domains, white labelling, payments, SSO and larger collaboration teams.

**Pricing & Plans:** Free tier for building and exploring, with preview-only publishing, 1 API, 1 Actionflow, 1 AI agent and capped resources. Basic is about $33 per project per month billed annually (unlimited APIs, Actionflows and agents, custom domain, white labelling, 1 collaborator). Pro is about $85 per project per month billed annually, adding Stripe payments, SSO, multiple clients, 10 collaborators and 30-day logs. Computing resources — database storage, object storage, outbound transfer, Actionflow runs and AI points — can be topped up as add-ons, and annual billing saves up to roughly 15%.

- **Visual AI agent builder:** Assemble agents visually from LLMs, data sources, tools and outputs, with support for pre-integrated models or bringing your own model from providers such as OpenAI, Gemini, Claude, Grok, Qwen and Cohere.
- **Full-stack backend included:** A structured database, REST APIs, Actionflow automation and a production-grade user system ship together, so the front end you build is backed by real infrastructure rather than a mock.
- **Business-aware context and tool calls:** Agents ground responses in your live database or connected APIs and can act — calling APIs, running Actionflows, querying data or delegating to other agents.
- **Typed structured output:** Agents return results in typed JSON formats so they can update database records or trigger workflows programmatically without fragile parsing.
- **Bring any front end:** Generate a UI in Lovable or Cursor via a prompt-based blueprint, or use Momen's own builder, and connect it to the same backend for a consistent full-stack iteration loop.

**Strengths:** Combines AI agent building with a genuine backend, reducing tool sprawl for non-technical teams; Model-agnostic, with pre-integrated LLMs plus bring-your-own-model support; Free tier is usable for building; paid plans are billed per project and scale with resources; Backed by established investors and hosted in the United States

**Limitations:** Publishing, custom domains and payments require a paid plan, so the free tier is really for exploration; Several capabilities — payments, SSO, connected-drive-style features — are gated to the highest tier; Resource limits are metered (RPS, storage, AI points, Actionflow runs), which requires cost monitoring as an app scales

## 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
