## 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

## Read Aloud Reader

Read Aloud Reader is a browser tool that reads text out loud using neural AI voices. You open the studio, paste anything with words in it — an article, an email, a chapter, study notes — or upload a PDF, DOCX or EPUB, then choose a voice and press play. There is no install step, no signup wall and no mandatory account: the whole workflow lives in a single web page.

The experience is built around following along. As the voice reads, the current sentence is highlighted in the reading pane, which is the feature that makes it genuinely useful for proofreading a draft by ear, following study material hands-free, or listening to an article on a commute while tracking where you are. Playback speed is adjustable across a wide range from half speed to double speed, so slow readers and fast listeners can both dial it in.

Practical details matter here. You can paste up to 40,000 characters in a session, import a PDF, DOCX or EPUB, or hand it an article URL and let it pull the text out for you. Anything you generate can be downloaded as an MP3, which means commutes, workouts and offline trips do not need a live connection. It runs identically on Mac, Windows, a Chromebook, an iPhone or an Android phone because it is a website, not an app. Accessibility is a core use case: people with dyslexia, ADHD, visual impairment or simply tired eyes use it to make reading easier, and the tool says text is used only to generate audio and is not stored or logged.

**Pricing & Plans:** Freemium. The free tier includes the neural AI voices and sentence highlighting with a 5,000-character daily allowance (20,000 per month) and no card or account required. MP3 download and heavier daily use sit in paid plans aimed at people who read long documents regularly.

- **Eight studio-grade neural voices:** Pick from neural AI voices with five reading styles so the output sounds like a person rather than a satnav, and set speed from 0.5x up to 2x.
- **Sentence highlighting as it plays:** Each sentence is highlighted while it is read, so you can follow along on screen, which is what makes it work for studying and proofreading by ear.
- **PDF, DOCX, EPUB and article URL import:** Paste plain text or upload a document, or drop in a link and the article text is extracted for you before playback.
- **MP3 export for offline listening:** Download the generated audio as an MP3 and keep it for commuting, the gym or any podcast app—no repeated regeneration needed.
- **Nothing to install, works in any browser:** It runs in a browser tab on Mac, Windows, ChromeOS, iPhone and Android with no signup, no extension and no desktop software.

**Strengths:** Genuinely free core tier with neural voices and no signup; Sentence-by-sentence highlighting makes it easy to follow along; Accepts pasted text, PDF, DOCX, EPUB and article URLs; Runs in any browser and exports MP3 for offline listening
