## 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

## Seedance 2.5 API

Seedance 2.5 API positions itself as a practical working site for engineers and product teams building video generation features. Rather than a simple landing page, it mixes a prompt-and-example gallery, step-by-step workflow guidance, an API quickstart with Python and JavaScript snippets, and a detailed pricing reference arranged by resolution and clip length. The latest generation, Seedance 2.5, is documented as a pending release — the site openly states that pricing and model access are not yet open and advises teams not to hard-code a model ID in production until routing is confirmed.

The currently usable baseline is Seedance 2.0, which the site routes through EvoLink and prices per generated video (for example $0.46 for a 480p 5-second clip up to $15.18 for a 4K 15-second clip). The workflow is deliberately simple: register and top up, send a RESTful generation request, then poll a task ID or receive a webhook when the video is ready. Commercial usage rights are included and no subscription is required.

The comparison tables contrast Seedance 2.5 against Seedance 2.0, Kling 3.0 and Veo 3.1 on resolution, duration, audio support and input modalities, giving teams a starting point for cost modelling before they commit engineering time. Because the site aggregates speculation and announced information about an unreleased model, its forward-looking specs should be treated as reference only, not a guarantee.

**Pricing & Plans:** Pay-as-you-go with no subscription required; Seedance 2.0 is billed per generated video (e.g. $0.46 for 480p/5s up to $15.18 for 4K/15s), while Seedance 2.5 pricing is listed as coming soon. Enterprise SLA and volume pricing are available on request.

- **RESTful video generation API:** Three-step flow — POST a prompt, poll the returned task ID, then download the finished video URL — with ready-to-copy Python and JavaScript snippets for text-to-video, image-to-video and reference-to-video.
- **Transparent cost reference:** Per-video and per-second pricing broken down by resolution and duration for Seedance 2.0, alongside public reference prices for Kling 3.0 and Veo 3.1 so teams can budget before building.
- **Seedance 2.5 vs 2.0 comparison:** A capability-by-capability breakdown covering resolution, clip length, reference assets, local editing, multilingual speech and physics simulation, with clear flags on what is announced versus confirmed.
- **Prompt and example gallery:** Real outputs generated through the API with the prompts that produced them, covering documentary, martial-arts restyle, VFX edit and fashion-film briefs.
- **Production onboarding guidance:** Documentation on API access status, model IDs, webhook callbacks and the evaluation criteria teams should test before making a new model their default route.

**Strengths:** Clear, per-video pricing math for Seedance 2.0 that makes production budgeting straightforward; Honest status reporting — the site explicitly labels Seedance 2.5 specs as announced/pending rather than confirmed; Ready-to-run Python and JavaScript API snippets lower integration time; Comparison tables put Seedance, Kling and Veo cost and capability side by side in one place

**Limitations:** Seedance 2.5 pricing and model access are not yet available, so the headline promise is still forward-looking; It is an independent third-party hub, not an official ByteDance product page, so specs should be verified against primary sources; Some competitor pricing on the comparison page is public reference data that can drift out of date
