## 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

## Sonilo

Sonilo approaches AI audio from the video side rather than the prompt side. Instead of starting with a text description and dropping the result onto a timeline, you upload your edited video and the system analyzes its timing, pacing, and emotional arc. It then generates a soundtrack whose length matches the video exactly, and places sound effects on the specific frames where actions happen. The output is a single finished audio track rather than a set of clips you have to cut and align yourself.

The same engine powers other workflows, including text-to-music, text-to-sound-effects, video translation with lip sync across 24 languages, audio ducking, and subtitle import so translations follow an existing .srt or .vtt file. Sonilo runs on the web and through a documented API at platform.sonilo.com, and it ships plugins for Adobe Premiere Pro, Unity, Godot, Epic Games Fab, the Roblox Asset Store, and the Defold Asset Store so creators can generate licensed audio without leaving their editor or engine.

Licensing is a central selling point. Tracks carry a commercial license from the Pro tier upward, covering ads, branded content, client deliverables, monetized channels, and indie games with no attribution; Premium adds film, TV, broadcast, and studio games. The company states its model is trained only on a licensed catalog rather than scraped material and provides a license certificate. Pricing is credit-based: one shared balance covers every model, billed by output length, with a free tier that gives 2,000 credits every two weeks but limits exports to preview quality for non-commercial use.

**Pricing & Plans:** Free tier at $0 with 2,000 credits every two weeks and preview-quality non-commercial exports. Pro is about $11.99 per month billed yearly at $143.88 and unlocks commercial licensing, 40,000 credits per month, longer uploads, and video translation. Premium is about $23.99 per month billed yearly at $287.88 and adds film, TV, and broadcast rights. Enterprise adds custom terms, volume credit rates, and dedicated support. Credits are consumed by output length: 18 per output second for video-to-music and video-to-sound-effects, 5 for text-to-music, and 4 for text-to-sound-effects.
