## 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

## VO4

VO4 is a browser-based AI video studio built around the promise of turning a written idea into a finished, shareable clip. The workflow is deliberately simple: describe the video you want (the site's own example is a giraffe riding a motorcycle in New York City), or upload an image to animate, then choose aspect ratio, quality, duration and the model you want to run. Processing runs server-side and takes a short wait rather than being instant.

Beyond the core generator, VO4 bundles a set of satellite tools — image upscaling, background removal for images and video, photo cleanup, watermark removal and an image extender — so creators can assemble a full short-form pipeline without leaving the platform. Output can be exported in HD and, notably, without a watermark even on free usage. The marketing angle is squarely on social content: rapid, low-cost marketing and promotional videos aimed at brands, freelancers and social media creators.

One important distinction: vo4ai.org is an independent third-party site. It markets generation using Google's VEO 4 model branding, but it is not a Google product and has no official connection to Google. Pricing is credit-based with a free starting allotment and paid plans; during our visit the Pro plan was advertised at $19.9 per month with annual billing discounted, but rates change, so check the live pricing page.

**Pricing & Plans:** Freemium, credit-based. The site advertises a free starting credit allotment and paid plans on top; during our visit the Pro plan was shown at $19.9 per month with annual billing offering roughly a 50% discount. Payments are processed by Stripe. Watermark-free downloads are available even without paying. Confirm current rates on the pricing page.

- **Text to video:** Generate clips by describing a scene, character and action in a text prompt, then pick aspect ratio, resolution and duration.
- **Image and photo to video:** Animate a still image or reference photo by combining it with a short prompt to bring the scene to life.
- **Quality and format controls:** Choose output resolution up to 4K, aspect ratios from 16:9 to 1:1, and clip lengths of 5 or 10 seconds.
- **Watermark-free export:** Download finished videos without a watermark, even on free usage, and export in HD.
- **Extra AI image tools:** A companion toolkit including image upscaling, background removal, video background removal and watermark removal.

**Strengths:** Multiple input modes: text, image or photo to video; Download export without a watermark, even on free usage; Resolution options up to 4K with flexible aspect ratios from 16:9 to 1:1; Bundled extra tools for upscaling, background and watermark removal

**Limitations:** It is a third-party site using the VEO 4 name — not a Google product, so official guarantees don't apply; Video generation takes a processing window rather than being instant; Credits are consumed per generation, so heavy use requires paid top-ups; Output quality and audio depend on the underlying model and will vary by prompt
