## 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

## Scribble Diffusion AI

Scribble Diffusion AI targets the gap between a napkin sketch and a presentable image. Instead of describing a picture entirely in words, you supply the composition itself — drawn in the browser or uploaded from paper — and add a prompt to control style, colour and material. The result is a refined image that preserves the structure of your sketch while filling in the rendering detail that is hard to draw by hand.

The workflow is a short loop: draw or upload, type a prompt, generate, then adjust the prompt and generate again. Because the sketch stays fixed between runs, it is easy to explore variations on one idea rather than starting over each time. A public Explore section collects outputs from other users, which is useful both for inspiration and for judging whether the model's style matches what you want before spending credits.

It is a browser-based paid service built around a credit system. A free plan provides a handful of credits, a one-off Starter pack suits occasional use, and Premium and Advanced subscriptions supply larger monthly allowances. The site states that payments run through Stripe and that refunds are not available, so it is worth testing with the free credits first. Note that this is an independent tool rather than an official release from any particular AI research lab.

**Pricing & Plans:** Freemium with paid credit packs and subscriptions. A free plan includes a small number of credits. The Starter plan is a one-off purchase of 100 credits. The Premium plan is a monthly subscription (300 credits) and the Advanced plan is an annual subscription (5,000 credits), both bundling high-quality output and faster generation. Seasonal discounts have appeared on the site, so check the pricing page for current figures.

- **Sketch or upload, then generate:** Use the built-in canvas to draw your idea, or upload an existing sketch, then submit it with a text prompt. The service renders a refined image that follows both the shapes you drew and the description you typed.
- **Prompt-driven variation:** Iterate by changing the prompt while keeping the same drawing, so a single sketch can branch into several visual directions — different colours, styles, materials or lighting on the same composition.
- **High-quality output and faster generation:** Images are returned in a high-quality format and paid plans prioritise generation speed, so you are not waiting on long queues when you are working through a set of ideas.
- **Explore gallery for reference:** A public Explore gallery shows what other users have produced, which is a quick way to understand the range of styles the model handles before you commit to a credit purchase.
- **Multi-language interface:** The interface and copy are available in several languages — including Simplified Chinese, Japanese, Spanish, German and French — making the workflow accessible to non-English speakers.

**Strengths:** Keeps the composition of your own sketch rather than inventing a scene from text alone; Free credits let you evaluate output quality before paying; One-off credit pack available for people who do not want a subscription; Prompt re-runs on the same sketch make iterating on a single idea quick

**Limitations:** Credit packs are consumed per image, so heavy experimentation adds up quickly; No refunds are offered once credits are spent on image processing; Results depend heavily on prompt quality, so a rough sketch alone will not guarantee a good render; Server-side generation means queue times can vary when the service is busy
