## 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

## OpnForm

OpnForm is a form-building platform aimed at teams that want modern form UX without the response caps and lock-in typical of commercial survey tools. The editor is drag-and-drop and supports both single-page and multi-step layouts, so a long intake questionnaire can be broken into a conversational flow. Fields can be governed by conditional logic, calculations and answer piping, and forms can be styled with custom themes, brand colours and fonts. AI assistance is available when you want it for drafting questions or fields, but it stays opt-in rather than being forced into the workflow.

What differentiates OpnForm most is its open-source posture. The full codebase is public and auditable, and organisations can choose between the vendor's hosted cloud, an EU-based cloud deployment, or running the software on their own infrastructure. That matters for companies with data-residency rules or internal security reviews. The product also ships team-oriented controls such as shared workspaces, roles and audit history for form and submission activity, along with SSO and SAML for enterprise accounts and 2FA support.

On the automation side, OpnForm connects to the tools teams already use. Submissions can flow to Slack, Discord or Telegram, sync to Google Sheets or Zapier, trigger notifications and routing rules, or be pulled through a documented REST API and webhooks. Payments are handled natively through Stripe, which makes it usable for registration fees and simple product orders. Forms can be distributed by link, embedded on a website or inside Notion, published on a custom domain, or exported as a QR code for offline collection.

**Pricing & Plans:** Freemium. A generous free tier includes unlimited form submissions with no per-response charges, and paid plans add more control, branding removal, team and enterprise features. EU hosting and self-hosting options are available; check the site's pricing page for current tiers.

- **Open-source, self-hostable form builder:** The full codebase is public and auditable, and you can run OpnForm on the vendor cloud, an EU-hosted instance, or your own infrastructure for complete data ownership.
- **AI assistance when you want it:** Optional AI help for building forms and fields, designed to stay out of the way when you would rather write everything yourself.
- **Smart logic and calculations:** Conditional logic, computed fields, answer piping, hidden fields and redirect-on-submit rules let one form adapt to many different respondents.
- **Unlimited submissions without per-response fees:** Collect as many responses as you need even on the free plan, with no hidden quotas or surprise overage charges.
- **Integrations, payments and API access:** Send data to Slack, Discord, Telegram, Google Sheets or Zapier, take payments via Stripe, and automate anything else with webhooks and a REST API.

**Strengths:** Genuinely open-source with a public codebase and self-hosting path; Unlimited submissions on the free tier with no per-response billing; Strong automation coverage through native integrations, webhooks and a REST API; Enterprise-ready controls including SSO, SAML, roles, audit history and EU hosting

**Limitations:** Self-hosting shifts update, backup and security responsibilities onto your own team; The deep feature set, especially logic and integrations, takes time to learn; Some enterprise compliance capabilities are still described as in progress rather than fully certified
