## Codex Pet

Codex Pet serves the fast-growing niche of OpenAI Codex desktop companions. Instead of juggling scattered spritesheets, manifest files, previews and download links across different tools, the site puts discovery, editing, remixing, validation and sharing in one browser workflow. Visitors can browse a public gallery sorted by hot, new, top or most-downloaded, then open any listed pet directly in the editor.

The editor is the core of the product. Creators can begin from a clean blank animation grid, inspect an existing public pet to learn its layout, or remix a pack into a variant. In-app visual checks flag transparency issues, animation rows and overall package readiness so packs remain installable after sharing. Packs typically bundle a manifest such as pet.json with a transparent spritesheet, and the site documents the format so other local Codex tools can read them.

Codex Pet is an independent community project and is not an official OpenAI product; OpenAI Codex is referenced only to describe compatibility. The site includes installation, creation and troubleshooting guides, a format specification for developers, and a dedicated CLI 'hatch-pet' tool for scaffolding packs. Access is free and packs are contributed by community members, with attribution, license and reporting flows built into listings.

**Pricing & Plans:** Codex Pet is free to browse and use, with downloadable community packs and in-browser editing tools offered at no charge. There is no paid tier advertised on the site; tips on attribution and licensing are shown per listing.

- **Browser sprite editor:** Start from a blank animation grid, inspect any public pet, or remix an existing pack and preview motion and transparency as you work.
- **Community pet library:** Browse and search community submissions sorted by hot, new, top and most downloaded, with previews, credits and descriptions for each pack.
- **Visual validation checks:** Built-in checks review transparency, animation rows and package readiness so your pet installs cleanly for other users.
- **Pack format documentation:** Developer docs cover the manifest, spritesheet layout and animation states so packs stay compatible across local Codex tools.
- **hatch-pet CLI:** A command-line helper and step-by-step guides walk you through installing and creating your first Codex pet pack.

**Strengths:** Free browser-based workflow with no local install required for editing; Clear pack format documentation and a dedicated hatch-pet CLI; Active community library with attribution, licenses and reporting built in; Supports the newer Codex Pet V2 format

**Limitations:** Independent community project, not an official OpenAI tool; Quality and licensing vary between community-submitted packs; No built-in hosting or marketplace guarantees for published pets

## 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
