## 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

## Stablecog

Stablecog puts the power of open-source image models into a browser tab. Rather than installing Python environments and wrestling with GPU drivers, you open the site, type a prompt, and generate art. It supports both text-to-image and image-to-image workflows, so you can start from a description or use an existing picture as a base and let the model iterate on it. Thousands of styles are available, from photorealistic to painterly to psychedelic.

As an open-source project, Stablecog is transparent about how it works and gives developers an API plus a history and public gallery where generated images can be browsed and remixed. The platform is multilingual, so prompts and the interface work across many languages, and the free tier is genuinely usable for experimentation: 20 images per day.

The tradeoff for free access is slower generation, single-image batches, public images and personal-use-only licensing. Paid subscriptions remove those limits, enabling much higher monthly volumes, parallel generations, private images and commercial usage rights, with optional credit top-ups for heavier months.

**Pricing & Plans:** Freemium. The Free plan allows 20 images per day with slow generation, single-image batches and public images for personal use only. Starter is $10/month for 2,000 images with fast generation and commercial rights, Pro is $25/month for 6,000 images, and Ultimate is $50/month for 12,000 images. Paid plans include 4-image batches, parallel generations, private images and optional credit top-ups; credits reset monthly.

- **Open-source image models:** Generate with Stable Diffusion, FLUX and Kandinsky without managing local GPU setups or Python environments.
- **Text-to-image and image-to-image:** Start from a written prompt or upload an existing image and have the model generate new artwork based on it.
- **Thousands of styles:** Describe almost anything and explore a huge range of visual styles, from photorealistic to fantasy and abstract.
- **Multilingual interface:** A localized web interface and multilingual support make image generation accessible beyond English speakers.
- **API and public gallery:** Developers can tap an API for programmatic generation, while the gallery lets users browse and draw inspiration from public images.

**Strengths:** Free tier is usable for real experimentation at 20 images per day; Open-source foundation with API access for developers; Simple, transparent monthly pricing with commercial rights on paid plans; Multilingual interface and gallery for inspiration

**Limitations:** Free generations are slow and limited to one image at a time; Free-plan images are public and restricted to personal use; Credits do not roll over between billing cycles
