## 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

## Thinking Line

Thinking Line is a browser-based creative studio for turning written ideas into visual stories. You enter a topic, pick a style, voice and number of scenes, and the platform generates a hand-drawn whiteboard explainer video with narration. Alongside video, it produces editable SVG graphics so teachers and designers can restyle or extend the artwork. Recent engine updates focus on smoother pen strokes and cleaner labels for a more natural doodle look.

The platform is built around practical use cases: classroom lessons on science, mathematics and biology; corporate training such as warehouse safety and cybersecurity awareness; and creative storytelling. A published showcase library lets you explore generated lessons for inspiration, and a voice library lets you assign different narration voices per request. Native animated scenes — bar charts, pie charts, graphs and cycles — can draw themselves inside lessons.

For developers and teams, Thinking Line exposes an API including a WebSocket generation endpoint, so video production can be embedded into other products or automated pipelines. Pricing starts with a free tier for experimentation and scales through a Pro plan to Enterprise agreements with custom branding, SSO and dedicated support.

**Pricing & Plans:** Free tier available ($0): 4 videos/month, standard voices, 720p export, watermarked. Pro is $29/month: 30 videos/month, premium AI voices including cloning, 4K export, no watermark, commercial usage rights. Enterprise pricing is custom and adds API access, dedicated support, custom branding, SSO and security.

- **Prompt-to-video generation:** Describe a topic and receive a multi-scene, narrated, hand-drawn explainer video rendered in a doodle style.
- **Editable SVG output:** Generate vector graphics you can open in design tools and restyle or extend for your own materials.
- **Native animated scenes:** Built-in bar charts, pie charts, graphs and cycle diagrams that draw themselves within your lesson.
- **Voice library and cloning:** Choose from multiple narration voices, with premium voice cloning available on the Pro plan.
- **Developer API:** Integrate video generation via REST and WebSocket endpoints for automated or embedded workflows.

**Strengths:** Free tier lets you test the full prompt-to-video flow before paying; Editable SVG output is useful beyond videos; Native chart and diagram animations suit teaching content; API and WebSocket access enable automation and integration

**Limitations:** Free plan caps output at 4 videos per month with watermarks; Voice cloning and 4K export require the paid Pro subscription; Enterprise features such as SSO require contacting sales
