## 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

## Websim

Websim is a browser-based playground where anyone can create interactive games, simulators and web pages for free, then share them with a large public community. The homepage opens straight into a live feed of projects, with the most popular items reaching hundreds of thousands of plays. Creation is AI-assisted, so you describe what you want rather than starting from a blank HTML file, which lowers the barrier for people who want to make something playful without a full development setup.

A defining part of the platform is remixing. Nearly every project can be opened, modified and republished, and the community explicitly builds on each other's work — a top item often lists dozens of derivative versions. The feed sorts by today, week, month and all time, giving a clear sense of what the community finds fun right now. Projects range from game parodies and simulator homages to generators and quirky interactive experiments.

Websim operates under Websim, Inc. and pairs the product with Discord and Reddit communities and an official blog. It is not positioned as a professional dev tool for production websites; it is a social, free-to-use space that aims to 'make the internet fun again' by making creation casual and multiplayer-friendly. If you want a quick, no-cost way to build or play interactive content with other creators, it is a very accessible starting point.

**Pricing & Plans:** Free to use. Websim presents creation and sharing of games, apps and web pages at no cost, and the site has no pricing or paid plan page.

- **AI-assisted game and page builder:** Describe or prompt what you want and build playable games and interactive web pages directly in the browser.
- **Remixing and community forks:** Open any project, change it and republish your own take — community remixing is built into the culture.
- **Trending project feed:** A popular community feed ranks projects by engagement across today, week, month and all-time views.
- **Shareable interactive content:** Games, simulators, generators and playful web apps all live in one browsable, shareable feed.
- **Active community channels:** Discord and Reddit communities plus an official blog keep creators connected and informed.

**Strengths:** Free to use with no pricing page or paywall; Creation needs no local development environment; Strong remix culture makes it easy to learn by adapting existing projects; Large, active community feed provides instant examples and inspiration

**Limitations:** Content quality varies widely since everything is community-generated; Publishing to the public feed means your projects are visible to everyone; Discovering the best projects is harder than on curated platforms; Not aimed at production-grade or commercial web development
