Access to AI models at no extra cost? Sunra MCP's calculation

Connected to Claude, ChatGPT, or Cursor, Sunra MCP charges for models at their manufacturer's API price, or less depending on the plan and commitment duration.

A creative platform that already combines a web app, an agent and an API for image, video, audio and 3D, Sunra now makes these models available to AI assistants through an MCP server. In Claude and ChatGPT, it is added as a connector at mcp.sunra.ai, with a browser sign-in and no API key, while Claude Code, Codex, Cursor, Antigravity and Grok use a setup prompt that installs Sunra's command-line tool and links the account. The catalog runs from Seedance 2.5 to Veo 3.1, with Kling 3.0, Nano Banana Pro and Meshy 6 for 3D along the way. Credits come from the same account as the web app, and the assistant can check the balance and estimate a generation's cost before running it, with nothing charged until the user confirms unless auto-confirm is on. The maker's price, then less depending on the plan

The pricing rule fits in one sentence in the announcement post: when a model's maker publishes an API price, Sunra charges that price with no added fees, and adjusts it when the maker changes its own. A credit is worth $0.01 on that basis, so one second of Seedance 2.5 at 720p with audio, sold by ByteDance at $0.2311, costs just over 23 credits. That price applies as is only to the Basic plan billed monthly, at $12 for 1,200 credits. The Pro and Creator plans lower the cost of a credit, and annual billing cuts it further: $0.0049 on Pro and $0.0037 on Creator, or 63% below the maker's price for the same number of credits. Unused credits do not roll over from one month to the next, according to the pricing page.

The headline prices posted on 𝕏, starting at $0.039 per second for Seedance 2.5, $0.004 per image for GPT Image 2.5 and $0.015 for Nano Banana 2.1, with a claimed gap of up to 81% below other platforms' API prices, do not specify the setting or the plan behind them. Neither the post nor the pricing page explains how they were calculated. A comparison that also shows where it loses

The post comes with a comparison of 41 model settings against Runway, Higgsfield, Krea, Pika, fal, Replicate, Magnific, OpenArt and Pollo, with each price linked to the public page where Sunra recorded it in mid-October. At the maker's price, the platform often ties and sometimes trails: Replicate charges 39% less for GPT Image 2, Pika offers Wan 3.0 to its members at 35% less, and Magnific lists Kling 3.0 Pro 46% below Sunra's rate, without stating whether audio is included.

On the Creator plan billed yearly, Sunra comes out ahead on 37 of the 41 settings, measured against competitors' highest individual annual plans or their API price when lower. The calculation assumes every included credit gets used and excludes temporary offers as well as unlimited plans. Four models stay out of the tables, Midjourney V8.1 and three versions of Suno, which are in the catalog but have no verifiable API price: Midjourney sells only subscriptions and Suno has no public API. Prompts passed on to each model maker

On its trust and security page, the company says it does not use prompts, uploads or generated content to train its own models, whether through the app or through MCP. That data still goes to the provider of the chosen model, such as OpenAI, Google, ByteDance or Kuaishou, and Sunra says it is securing written no-training and no-retention commitments from those providers. A sub-processor list details the data each one receives and the region where it is processed, which may be the United States or elsewhere.
