## Melius

Melius is an AI-native operating system for creative work. Instead of juggling separate image, video and audio tools, you describe what you want and Melius routes the request to the right model, runs the workflow, and keeps every prompt visible so you can steer the output until it lands exactly as you imagined. The company has raised $25M in funding and is used by creative teams across advertising, e-commerce, filmmaking, fashion and branding.

The workspace is built around a node-based canvas. Rather than accepting a single one-shot generation, you assemble tunable, multimodal nodes that each handle a specific part of the job. Scenarios include product mockups, pack shots, PDP and lifestyle imagery, on-model fashion visuals, storyboards, animated statics, lookbooks, treatment decks, website mockups, OOH billboards and localized marketing content, all with prompt visibility and consistency across frames.

Melius also adds collaboration and channel reach: shared workspaces, agents you can connect to Slack, custom AI voices including ElevenLabs voices, AI search and prompt enhancement. Pricing moves from individual Creator and Growth tiers through Professional and pooled Team seats, with credit allowances scaled so heavier video work can be increased as needed.

**Pricing & Plans:** Freemium with a free start, then monthly or annual individual tiers (roughly $17 Creator, $43 Growth, $248 Professional at annual pricing, each with a monthly credit allowance) plus pooled Team seats and custom Enterprise pricing. Credits are shared across available models, with image and video generation consuming them at different rates.

- **Intelligent model routing:** Melius selects the appropriate image, video or audio model for each step, so you are not locked to a single vendor's capabilities.
- **Node-based creative canvas:** Work happens on a node-based canvas where prompts stay visible and each generation is a tunable step you can re-run or adjust.
- **Multimodal generation:** Go from product mockups and pack shots to ad variants, storyboards, lookbooks and animated statics without leaving the workspace.
- **AI agents and collaboration:** Built-in agents plus Slack access, custom voices, prompt enhancement and AI search support both solo creators and shared team workspaces.
- **Campaign-scale workflows:** Agencies and in-house teams can run concept boards and full campaign-volume variants on the same canvas.

**Strengths:** Model routing means access to the best model per task instead of one fixed engine; Prompt visibility and node-based tuning give real creative control; Covers image, video and audio in one workspace rather than separate subscriptions; Shared workspaces, Slack agent and custom voices suit team workflows

**Limitations:** Credit consumption varies a lot by model, so heavier video work burns credits quickly; Best value comes from learning the node-based canvas, which has a learning curve; Individual tiers have monthly credit ceilings that larger teams outgrow

## 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
