## 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

## SKI

SKI is a voice-first coding harness that runs on your Mac. Its premise is that coding agents are now fast enough that the real constraint is human attention: five agents working in parallel still have one pair of eyes reviewing them, and output has outpaced anyone's ability to read it. SKI's answer is to make the interface conversational, so you find out what your agents did by listening rather than reading, and acknowledge them in about the time a spoken reply takes.

The harness sits above agents rather than replacing them. It runs Claude Code, Codex, Cursor, OpenCode, Antigravity and others side by side, each on its own task, using the accounts you already pay for. Because it isn't tied to any model vendor, you can send hard reasoning to an expensive engine and bulk work to a cheap open-weight one. An orchestration layer keeps the context of every project, branch and chat, so you can ask where things stand and get one spoken answer — and chain agents together, such as having one plan a feature and another build it.

Git integration is built in: every chat gets its own branch and isolated worktree, live diffs are visible as agents work, and you can open a pull request by voice. Safety is treated as a design requirement rather than an add-on — SKI reconstructs the instruction it believes you meant from project context, shows it for review before the agent sees it, and asks for confirmation on anything irreversible. Your projects, code and chats stay on your Mac and run on your own agent accounts, while voice audio passes through the cloud for understanding but isn't stored. Pricing keeps text usage free forever, with credits spent only on real-time voice.

**Pricing & Plans:** SKI is free forever for text: unlimited typed chats with every supported agent and project on the Free plan. Voice is credit-based — Free includes 300 voice credits/month and 2 concurrent voice sessions, Pro is $20/month with 2,000 credits and 12 sessions, and Enterprise offers custom team rates. Top-up credits last 12 months.

- **Hands-free voice loop:** Talk to your agents and hear spoken replies in real time, so you can ask for a change, hear the result and answer the follow-up without returning to the keyboard.
- **Cross-project orchestration:** SKI keeps project, branch and chat context across every project, and hands each job to the right agent when you ask where things stand.
- **Git built in:** Each chat gets its own branch and worktree so parallel agents never collide; watch live diffs and open a pull request by voice.
- **Multiple agents, one hub:** Run Claude Code, Codex, Antigravity, OpenCode and others simultaneously, each on its own task, with a notification the moment one needs you.
- **Multilingual commands:** Speak in your own language or mix two; SKI interprets the intent and converts it into a precise instruction for the agent.

**Strengths:** Neutral harness that works with the agent subscriptions you already pay for; Unlimited text usage free forever, with credits only spent on voice; Real-time spoken talkback instead of reading logs; Git branches, worktrees and PRs handled by voice
