## 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

## PoseTracker API

PoseTracker solves a specific problem: most digital fitness products are blind coaches. They play a video, hand out a plan, and never look at the person actually moving. PoseTracker gives the product eyes by running pose estimation on the phone itself, so a camera feed becomes 17 COCO keypoints in real time without uploading video anywhere.

The stack is built for shipping fast. A React Native package (works in Expo Go) and a browser JavaScript build both use the same on-device MoveNet engine, so keypoints are free and require no API key. When an app needs semantics on top of raw coordinates — is that a valid squat rep, what is the knee angle, does this push-up meet form criteria — an optional API key unlocks a hosted engine that returns reps, angles and a form score. A classic WebView or iframe integration remains available for teams that already embed a web view.

Beyond reps, the platform offers built-in tools including a back flexibility test, a flexibility analysis tool with automatic angle detection, and a pose comparison system that scores a user against a reference position. Browser benchmarks published by the team put MoveNet Lightning around 51 FPS on an iPhone 12 and 34 FPS on a Pixel 5. On-device inference means the video stream never leaves the device, which simplifies privacy and cuts bandwidth for fitness and rehab use cases.

**Pricing & Plans:** Freemium with a paid developer tier. The free plan covers keypoints at no API key plus up to 200 tracking API calls per month and 100 AI assistant credits, restricted to non-commercial use. The Developer plan is €50 per month with 1,000 tracking API calls included and commercial use, and a tailor-made Business plan is available on request.

- **On-device MoveNet keypoints:** 17 COCO keypoints stream directly on the phone or in the browser with no API key and no video upload.
- **Rep, angle and form engine:** An optional API key returns repetition counts, joint angles and a movement form score for exercises like squats and push-ups.
- **React Native and web SDKs:** One engine with three integration paths: native React Native (Expo Go), browser JavaScript, and a WebView or iframe embed.
- **Built-in motion tools:** Ready-made back flexibility test, flexibility analysis with automatic angle detection, and pose comparison against a reference position.
- **Custom movement support:** Describe a movement, context and stack and the in-page assistant returns a React Native, Expo or web snippet on the same engine.

**Strengths:** Keypoints run on-device, so video never leaves the phone; Free tier with 200 API calls per month makes prototyping inexpensive; One engine covers React Native, iOS, Android, web and low-code embeds; Additional form scores, angles and flexibility tools go beyond raw keypoints

**Limitations:** The free tier is limited to non-commercial use and a strict monthly call cap; Semantic outputs such as reps and form scores require an API key and credit balance; On-device accuracy depends on phone hardware, lighting and camera framing
