## Onepage

Onepage positions itself as a single platform where a business can launch and grow its website with AI rather than stitching a builder, a CMS, a form tool, and an SEO plugin together. The core of the product is an AI agent that takes natural-language requests, plans the steps, and executes them across your account. Ask it to create pages for six locations in one layout, move old projects into the CMS with redirects, translate the whole site into Spanish and French, or add a booking form that feeds your CRM, and it carries the work through in one place.

The platform deliberately keeps a human in the loop. Nothing changes until you approve the agent's plan, every task has its own tab and history, and version history lets you restore any earlier version of a page. Built-in CMS, forms, CRM, tracking, analytics, cookie banners, EU hosting, and multilingual support mean the essentials arrive without plugins. Because every section is custom React code, the agent can build unusual layouts and animations, while you can still adjust each section by hand.

For teams that already use external AI tools, Onepage offers an MCP integration so Claude, Cursor, or Codex can operate directly inside your live project on every paid plan. The company reports it is trusted by more than 20,000 businesses and agencies, and holds a 4.8 rating on G2.

**Pricing & Plans:** Onepage is freemium. You can start for free without a credit card, and paid plans add agent credits, seats, collaboration features, and MCP access. Exact tier pricing is listed on the pricing page.

- **Onepage agent:** Describe a task in plain language and the agent plans the steps and completes them across your projects, from single pages to whole-site changes.
- **AI plus manual editing:** Create with AI and then fine-tune any section by hand in its settings, so you keep full control over the final result.
- **Built-in CMS:** Run a blog and any custom content, edit with AI, and manage versions, redirects, scheduling, and multilingual pages in one place.
- **Lead generation and marketing:** Capture leads, send auto-replies, run multi-step forms, and push data to your CRM with tracking and A/B tests built in.
- **SEO, GEO, and compliance:** Every page gets SEO and GEO settings, EU hosting, cookie banners, SSL, and llms.txt support out of the box.
- **MCP for external AI:** Connect Claude, Cursor, or Codex over MCP so external AI can work across your entire Onepage account.

**Strengths:** One platform replaces separate builder, CMS, forms, CRM, and SEO tools; Chat-based agent handles complex, multi-step website work; Approval step and version history keep changes under control; MCP support lets Claude, Cursor, or Codex work inside live projects

**Limitations:** Newer agent and CMS features are rolling out, with some still marked as coming soon; Custom-coded sections may feel less familiar to designers used to pure visual editors; Pricing scales with agent credits for heavy usage

## 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
