## 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

## TextSight

Most AI-detector sites stop at a percentage. TextSight is built as a workflow instead: you detect, you fix the flagged sentences with the built-in humanizer, and you re-run the check in the same tab to see whether the score actually improved. That loop is the core of the product, and it is why detection and rewriting live under one roof rather than in two separate subscriptions.

Under the hood there is a multi-model detector trained on output from ChatGPT, Claude, Gemini, Llama and Mistral, a 0–100 Humanization Score, and a rewrite engine that only touches the passages you flag. Around that core sit roughly twenty smaller writing utilities — grammar, readability, paraphrasing, summarisation, translation — plus a Chrome extension and add-ons for Word and Google Docs.

TextSight is unusually forthcoming about the limits of detection. It published a benchmark of 1,180 human-written academic papers from 2018, before GPT-3 existed, and reports a 5.85% false-positive rate on that corpus, with the dataset, analysis script and methodology downloadable. The company explicitly labels this its own testing rather than independent third-party validation, and tells educators to treat any score as one signal rather than proof.

**Pricing & Plans:** Freemium. The free tier gives 3 actions a day (around 1,000 words per scan without an account, ~1,500 with one; 260 words per humanization) using the same detector as paid plans. Starter is $9.99/mo, Pro $19.99/mo, Business $39.99/mo and Enterprise $79.99/mo, with annual billing discounting roughly 63%. Lower tiers include 20 daily actions and 40,000 humanizer words a month; Pro adds file upload and 5,000 API calls; higher tiers add team seats, bulk scanning, SSO and more API volume. No card is required to start, and plans can be changed or cancelled from settings.

- **Sentence-level AI detection:** Every sentence gets its own AI confidence score and colour code inside your text, so you can see which lines to fix instead of reacting to one blunt overall verdict. Sentence-level detail starts on the Starter plan.
- **Humanization Score:** A 0–100 score that rises as your writing becomes more natural, recomputed on every scan so you can watch the number move as you edit.
- **Targeted AI humanizer:** The humanizer rewrites only the passages that read as AI-written, keeping your meaning and tone. Free accounts get around 260 words per rewrite; paid plans add thousands of words a month plus Advanced, Business and Casual modes.
- **Detect, humanize, recheck in one place:** Detection, rewriting and re-scoring happen in one window. After a humanize pass you recheck the same text and compare the before-and-after AI percentage side by side.
- **Writing toolset and integrations:** About 20 supporting tools cover grammar, readability, paraphrasing, summarisation and translation, with a Chrome extension for right-click scanning of any text in your browser and add-ons for Word and Google Docs.

**Strengths:** Detection, humanizing and rechecking all happen in one window with no copy-paste between tabs; The free tier runs the same detector as the paid plans, so accuracy is not paywalled; Sentence-level flags point at specific lines rather than giving a single opaque score; The company publishes its own false-positive benchmark, dataset and methodology

**Limitations:** \"Humanization Score\" and AI probability are its own detector's numbers, so they are not an independent verdict; Heavy users (bulk files, folder libraries, team seats) must move to mid or top tiers; Detector accuracy is calibrated mainly on English text; other languages are weaker; False-positive testing is self-run and the vendor explicitly says it is not third-party validation
