## 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

## Supavoice

Supavoice is a macOS utility for people who would rather speak than type. It captures audio from your microphone, sends it to OpenAI, and returns a highly accurate transcript that you can drop into any application on your Mac via a global shortcut. Because it works system-wide rather than inside one editor, it fits into existing habits in Mail, Slack, notes apps, or a code editor without changing your workflow.

What separates it from many dictation tools is the formatting layer. Instead of raw stream-of-consciousness text, Supavoice can shape the result: an Email mode produces structured messages with greetings, Note mode organizes ideas into bullet points, and Message mode keeps a casual conversational flow. A custom mode lets you define your own rules, and a personal dictionary handles technical terms, acronyms, and proper nouns so names come out correctly capitalized.

The commercial model is deliberately simple. It is a one-time purchase paired with your own OpenAI API key, which means there is no subscription and your audio goes directly from your machine to OpenAI rather than through the vendor's servers. The trade-offs are that this is macOS-only, you need to manage your own API key and usage costs, and refunds are not offered on the instant digital delivery.

**Pricing & Plans:** Paid, one-time purchase (sold as a digital download via Gumroad). There is no subscription; you also pay OpenAI directly for API usage based on your own key and volume.

- **System-wide dictation shortcut:** Trigger transcription from anywhere on your Mac with Command+Option+V and paste the result into whatever app has focus.
- **Multiple formatting modes:** Simple, Email, Note, Message, and custom modes shape the output into punctuation-correct prose, structured emails, bullets, or casual chat text.
- **Custom vocabulary:** Add industry jargon, acronyms, and names so specialist terms are spelled and capitalized the way you expect.
- **One-time purchase model:** Buy once and bring your own OpenAI key instead of paying a recurring subscription fee.
- **Lightweight menu bar app:** Runs quietly in the menu bar with minimal use of system resources.

**Strengths:** Global shortcut works across every application on macOS; Context-aware formatting modes save editing time after dictation; No subscription — a single purchase plus your own API costs; Audio is not routed through or stored on the developer's servers

**Limitations:** macOS only, with no Windows or Linux version; Requires your own OpenAI API key, which is an extra setup step; All sales are final, so there is no refund if it does not fit your workflow
