About Moonshot AI and Kimi Models

Moonshot AI develops Kimi, a series of open-weight multimodal language models for coding, reasoning, knowledge work, tool use, and visual understanding. This MoonshotAI models collection brings together the Kimi APIs currently supported on GPTProto, allowing developers to compare live Model IDs, context limits, capabilities, and token pricing in one place. The catalog is updated as new AI models by MoonshotAI become available, while the same GPTProto account and shared balance can also be used across other supported providers.

Why Use MoonshotAI with GPTProto?

Use Kimi models through one shared API setup without deploying and maintaining the model weights yourself.

Live, Comparable Pricing

Compare GPTProto and reference token rates directly on each live model card before deployment.

One Key, Shared Balance

Use one GPTProto key and balance across Kimi and other supported text, image, video, and audio models.

Easier Model Switching

Switch compatible Kimi models by changing the Model ID, then review the model-specific reasoning controls.

Hosted API Access

Run Kimi through a metered API without deploying or maintaining large open-weight models yourself.

How to Access MoonshotAI Models

2
Generate an API Key
Create a key in your dashboard and store it securely in your application or server environment.
3
Call a Kimi Model
Point an OpenAI-compatible client to GPTProto, then select any live Kimi Model ID from the catalog above.

MoonshotAI API Models FAQ

Which MoonshotAI models are available on GPTProto?

The live MoonshotAI model list on this page is the current source of truth. GPTProto updates the catalog when new supported Kimi models are added or availability changes.

Do I need a separate Moonshot AI API key?

No. You can access supported Kimi models with a GPTProto API key and use the same GPTProto balance across other supported providers.

Does GPTProto store API prompts, images, videos, or outputs?

GPTProto does not retain prompts, images, videos, or outputs submitted through API requests. Content created through GPTProto’s online generation tools is retained so users can access it later. No fixed online-generation retention period is stated on this provider page.

Are failed, timed-out, or blocked requests charged?

No. Requests that fail, time out, or are blocked are not billed.

Are MoonshotAI model versions fixed on GPTProto?

The catalog is not fixed. GPTProto adds newer supported MoonshotAI models and updates model availability as the catalog changes. Verify the live Model ID before production deployment instead of relying on an older page snapshot.

What happens if an upstream service becomes unavailable?

GPTProto automatically falls back to another available route when the current upstream route is unavailable.

Does GPTProto expose MoonshotAI’s native model parameters?

Yes. GPTProto exposes the native MoonshotAI parameters supported by each listed model. Parameter names and valid values may differ between K3 and K2-series models, so review the selected model page before switching.
