## Captions

Captions is an AI video editor built around a single promise: go from footage or a plain idea to a shareable video without learning a timeline. You upload a clip or start from scratch, pick a style, and its AI editor returns a finished cut with scene changes, zooms, B-roll overlays, music, transitions and stylized captions already in place.

The editing experience is conversational. Instead of dragging clips, you describe what you want changed in plain language and the chat-based editor applies it, which lowers the barrier for people who have never edited before. Alongside that, Captions ships a broad toolbox: automatic captions with animated fonts, subtitle translation into 100+ languages, AI avatars and digital twins for presenter-led content, royalty-free music and sound effects, and cleanup utilities that fix inconsistent eye contact, strip background noise and trim filler words.

Captions is used heavily for short-form social content, ads, podcast clips, tutorials and product demos, and it works on both vertical and horizontal footage. The product line was recently consolidated: Mirage Studio, its earlier avatar-focused app, was merged into Captions, so existing Mirage projects and actors now appear inside the Captions workspace. Pricing is freemium — registration is free and some tools are available without a subscription, while the full feature set requires a paid plan.

**Pricing & Plans:** Freemium. Creating a Captions account is free and a subset of features works without paying, but access to the full editing suite, higher-quality output and the broader AI tool set requires a paid subscription. Plan tiers are listed on the Captions pricing page, and the app is available free on iOS, Android and the web.

- **AI Edit with style presets:** Pick a visual style and Captions cuts scenes, adds zooms, overlays B-roll and music, and returns a fully edited video in one pass.
- **Automatic captions and subtitles:** Generate animated word-level captions with stylized fonts, or translate and subtitle content in more than 100 languages.
- **AI avatars and digital twins:** Create a digital twin or choose from a library of ready-made avatars, then reuse the same presenter across topics with prompt-based changes to outfits and backdrops.
- **Prompt-based chat editing:** Direct changes with simple text prompts, so beginners can make advanced edits without knowing a timeline editor.
- **Studio-grade cleanup tools:** Correct inconsistent eye contact, remove background noise, and trim pauses and filler words automatically.

**Strengths:** Turns raw footage into an edited video in minutes without timeline skills; Automatic captions, translation and avatars all live in one app; Chat-style prompt editing makes advanced changes approachable for beginners; Works on desktop and mobile with separate iOS and Android apps

**Limitations:** Most professional-grade output requires a subscription rather than the free tier; Style presets may look formulaic on niche or highly branded content; Auto-generated captions and edits still benefit from a human pass before publishing

## 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
