## ComfyOnline

ComfyOnline hosts ComfyUI — the popular node-based interface for diffusion models — in the browser. You build or import node graphs using the same custom-node ecosystem people run locally, but the heavy compute happens on cloud GPUs such as the RTX 4090, A6000, L40S, A100 and H100. Editing a workflow is free; you are only charged for the seconds a workflow actually runs, which matches the serverless model the team advertises.

The distinguishing piece is deployment. Instead of leaving a graph as a one-off experiment, ComfyOnline can automatically generate an API endpoint for it, so a workflow becomes a callable service you can wire into your own product. The platform also brokers third-party model providers inside the same canvas: video generation through Kling, Runway, Luma, Pika and Wan; image generation through Flux Pro Ultra, Ideogram and Recraft; speech through ElevenLabs; and chat/LLM calls to Claude, Gemini, GPT and DeepSeek. That makes it a single control panel for mixing open-source diffusion pipelines with commercial model APIs.

Pricing is credit-based rather than flat. Top-ups start around $10 and scale up, and monthly membership tiers (Personal, Startups, Business) add larger credit bundles, relax-mode queueing and customization including private LoRAs and models. Because generation cost depends on the GPU class and runtime, teams should treat the per-second credit rates as the main planning input.

**Pricing & Plans:** Freemium-style: editing workflows is free and you pay only for runtime. Pay-as-you-go credit packs start around $10 (with bonus credits), and monthly membership tiers such as Personal, Startups and Business unlock larger credit bundles, unlimited relax-mode queues and custom deployment options.

- **Cloud ComfyUI workspace:** Build and run node graphs in the browser on 4090, A6000, L40S, A100 or H100 GPUs, with the common custom-node packs preinstalled.
- **One-click API deployment:** Turn any workflow into an auto-generated API endpoint so it can be called from your own apps and services without writing the serving layer yourself.
- **Built-in model brokers:** Access Kling, Runway, Luma, Pika and Wan for video, Flux Pro Ultra, Ideogram and Recraft for images, ElevenLabs for voice, and Claude, Gemini, GPT and DeepSeek for text inside the same canvas.
- **Pay-per-second billing:** Editing costs nothing; you are billed only for the seconds a workflow executes, with idle GPUs never charged.
- **Private models and scaling:** Upload private checkpoints and LoRAs, and let deployments scale automatically when traffic grows.

**Strengths:** No local GPU needed; runs on high-end cloud cards; Workflow-to-API generation removes a big chunk of backend work; Wide list of third-party video, image, audio and LLM integrations; Transparent per-second credit pricing with no idle charges

**Limitations:** Credit-per-second math takes some effort to forecast real spend; Some advanced GPU tiers require specific plan upgrades; Documentation and enterprise terms are thinner than larger cloud vendors

## 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
