## 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

## Suno API (TTAPI)

Suno Music API on TTAPI gives developers programmatic access to Suno's music models without managing their own Suno accounts or browser automation. You authenticate with a TT-API key, POST a prompt, custom lyrics, or a public audio URL, then poll a fetch endpoint or receive the task result by URL once the generation finishes. The catalogue covers 30+ documented operations, from plain text-to-music and lyric writing to stems, remastering, mashups and MIDI export.

Billing runs on a single prepaid balance metered in "quota", where 1 quota is worth about one US cent. Most generation and editing operations cost 6 quota per task, stem separation costs 12, full multi-track stem splitting costs 30, and light operations such as cropping, fade in/out or lyric generation cost 1 quota. New accounts start with a free quota allowance so you can test an endpoint before topping up, and the same balance covers TTAPI's image, video and language models if you later need them.

Because the service resells Suno on shared infrastructure, it is important to treat it as an independent platform: it is not officially affiliated with Suno, output may be subject to the upstream provider's limits, and the request schema mirrors Suno's task model with TTAPI-specific model names such as chirp-v6 variants. Media files are returned as temporary URLs, so the documentation advises caching downloads rather than re-requesting them, which would incur the download charge again.

**Pricing & Plans:** Pay-as-you-go from a shared prepaid balance metered in quota (1 quota ≈ $0.01), with a free starter allowance. Generation and editing tasks are typically 6 quota each, stem separation 12, all-stems 30, cropping/fades/lyrics 1, speed adjustment 3, sound effects 1.2, audio upload 0.5 and custom model training 60. max_mode doubles the base generation cost. Enterprise volume rates are available on request.

- **Text-to-music and lyrics:** Generate full songs in inspiration or custom-lyrics mode, or produce standalone lyrics and upsampled style tags from a short brief.
- **Covers, extends and uploads:** Continue an existing track from a chosen point, create cover versions, or upload a public audio URL and extend or cover it in a single request.
- **Stem separation and editing:** Extract vocals, instrumental or a complete multi-track stem set, then remaster, mash up, replace or remove sections, crop, fade and adjust speed.
- **Custom models, voices and personas:** Train a private Suno model from 6-24 reference tracks and create reusable voices or personas for consistent output.
- **Async REST with webhooks:** Every heavy operation returns a task that you poll via the fetch endpoint or receive by callback, with CDN-hosted mp3, m4a, wav and MIDI delivery.

**Strengths:** Very broad Suno operation coverage, from simple prompts to stems, MIDI and music videos; Transparent per-action quota pricing with a free starter allowance and no subscription; One API key and one balance across music, image, video and LLM endpoints; Comprehensive public API reference with request fields for every endpoint

**Limitations:** Third-party reseller, not an official Suno product, so upstream changes can affect availability; Results are asynchronous tasks, so polling or callback handling is required; Returned media URLs expire and repeat downloads are billed again; Costs are quoted in internal quota units that you must convert to real money yourself
