## 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

## Struct2AI

Struct2AI addresses a routine frustration in AI-assisted development: assistants give vague or wrong answers when they cannot see how your project is actually organised. The tool works as a context bridge. You point it at a local project folder or connect a GitHub repository — private repositories included — and it captures the directory structure together with the contents of whichever files you choose. The result is an AI-friendly representation you can paste straight into ChatGPT, Claude or another assistant so its suggestions reflect your real file layout, naming conventions and module boundaries.

The interface is deliberately minimal and built around three steps shown on the site: scan your project, select and copy what matters, then paste into your AI tool. Smart file selection lets you combine several files into one copyable block rather than exporting an entire tree, which keeps prompts focused and within context limits. The makers promote speed, highlighting analysis of large project structures in seconds, and there is a demo video on the homepage that walks through the workflow.

Struct2AI is a small, focused developer utility rather than a full IDE or code-generation platform — it prepares context and hands it to the AI you already use. The public page does not publish specific pricing numbers; it refers users to in-app pricing and an FAQ that also covers refunds, project-size limits and data security. Note that the product runs its own site at www.structai.in, which is separate from the unrelated other business now hosted on the bare structai.in domain.

**Pricing & Plans:** The public site points to in-app pricing and an FAQ covering cost and refunds rather than listing specific figures, so treat pricing as free-to-try with paid tiers whose exact amounts should be confirmed on the site or in the app.

- **Local and GitHub structure capture:** Scan a local folder or fetch a repository structure from GitHub in seconds, including private repositories, and view it as a clear tree before exporting.
- **Selective file copying:** Pick specific files and merge their contents into one block, or copy the whole folder tree in a single click.
- **AI-ready output format:** Output is formatted so it drops cleanly into ChatGPT, Claude and similar assistants, giving them an accurate picture of your codebase layout.
- **Fast scanning of big projects:** The site markets fast analysis of large project structures so the context-gathering step does not slow your workflow.
- **Simple three-step workflow:** A web dashboard plus a short demo walkthrough take you from scan to paste in three steps: scan, select and copy, paste into your AI tool.

**Strengths:** Works with local folders and GitHub repositories, including private repos; One-click copy of folder structure or merged selected file contents; Output formatted to paste cleanly into ChatGPT, Claude and similar tools; Marketed as fast even on large project structures

**Limitations:** Root URL intermittently returns HTTP 500 headers, which looks alarming even though content still renders; No public pricing page is reachable, so costs must be confirmed inside the app; Assumes you work with ChatGPT, Claude or another large-context AI that accepts pasted text; Best suited to modest projects — extremely large repos can still strain an AI context window
