## 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

## Seko

Seko is an AI video creation platform developed by SenseTime. Rather than treating video generation as a single text-to-clip step, it is built as a full studio: you describe an idea in natural language, and an agentic Creator workflow helps you turn that idea into a structured production with script, storyboards, character images, and generated video. The result is aimed at creators who want finished short-form narrative video, not isolated clips.

The core workspace is an infinite canvas, where characters, reference images, and scenes can be arranged, reused, and refined across a project. Seko emphasizes serialized content such as short dramas, comic-style episodes, knowledge-sharing videos, and music videos, and it includes inspiration-driven modes that plan content automatically from a short prompt. Batch prompt upload and reusable character assets make it practical to produce multi-episode series with consistent visuals.

The platform also functions as a community. A public gallery lets creators publish and browse AI video works, follow serialized series, and learn from tutorial-style canvases. Seko is a paid, credit-based platform, and it periodically offers limited-time free access to select models and features, so current pricing and promotions are best confirmed on the official site.

**Pricing & Plans:** Seko uses a paid, credit-based model with trial access to some models and features, and it periodically runs limited-time free offers. Because prices and promotions change often, check the official Seko site for current tiers and credits.

- **AI Creator Agent:** Start from a plain-language idea and let the Creator Agent draft content, plan scenes, and generate a video for you.
- **Infinite Canvas Workspace:** Organize characters, shots, and scenes freely on an unlimited board, with batch prompt upload to scale storyboard production.
- **Multi-Episode and Short-Drama Workflows:** Built for episodic content, so you can maintain characters, style, and continuity across multiple episodes and comic-style series.
- **Unified Script-to-Video Pipeline:** Combine scriptwriting, image generation, and video generation in one place instead of stitching together separate tools.
- **Community Gallery and Creative Modes:** Explore, publish, and remix community works, and use built-in modes for overseas short dramas, comic dramas, knowledge clips, and music videos.

**Strengths:** Covers the whole pipeline from idea and script to storyboard and finished video; Infinite canvas gives fine control over scenes and reusable character assets; Strong fit for serialized short dramas, comic episodes, and themed content; Active community gallery with real examples and tutorials

**Limitations:** Interface and community content are heavily Chinese-first, which can be less convenient for English-only users; Paid credit-based model, and heavy video generation can get costly; Advanced results still depend on careful prompt and shot planning
