## Use Kimi K3.1 Pro in your assistant

Paste this prompt into Claude Code, Codex, Cursor or any agent. It reads the guide and helps you connect.

```
Read https://flymy.ai/skill.md and https://flymy.ai/mcp/models/kimi-k3-1-pro.md. Help me connect the FlyMy.AI MCP to this assistant, then run Kimi K3.1 Pro (flymyai/kimi-k3_1-pro) for this task: Ask Kimi K3.1 Pro: write unit tests for this Python module.

## What Kimi K3.1 Pro does

Send a prompt or messages (images as image_url parts). It thinks before it answers: reasoning_effort is none, low, medium (the default) or high. Through the OpenAI-compatible endpoint it calls your function tools; force a call with tool_choice 'required'. service_tier priority buys Moonshot's faster serving and private_mode keeps the exchange out of FlyMy.AI storage.

## Kimi K3.1 Pro inputs

Every input of `flymyai/kimi-k3_1-pro` as its live schema lists them. Returns `output` (string), `finish_reason` (string), `service_tier` (string), `reasoning` (string), `stream_details` (string).

| Input | Type, values and default |
|---|---|
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-prompt) `prompt` | string required What to ask Kimi |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-messages) `messages` | string optional Chat history as a JSON array of {role, content}; used instead of the prompt |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-system_prompt) `system_prompt` | string optional Instructions for the whole chat |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-reasoning_effort) `reasoning_effort` | string optional Allowed: none, low, medium, high Default: `medium` How hard it thinks before answering; none answers at once |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-service_tier) `service_tier` | string optional Allowed: default, priority Default: `default` priority: Moonshot's faster Highspeed serving, at the priority price |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-max_tokens) `max_tokens` | integer optional Allowed: 1 to 943718 Most tokens to generate, reasoning included |
| [#](https://flymy.ai/mcp/models/kimi-k3-1-pro/#input-private_mode) `private_mode` | boolean optional Default: `false` Keep the prompt and the answer out of FlyMyAI storage and logs (synchronous requests only) |

## Call Kimi K3.1 Pro from code

The same model, from an agent or from your own code. Keys stay in your FlyMy.AI account.

### From an agent, through the MCP

The agent calls `get_model_schema`, then `run_model` with:

```
{
  "endpoint_id": "flymyai/kimi-k3_1-pro",
  "input": {
    "prompt": "Explain in two sentences what an MCP server is."
  }
}
```

### From your code, over HTTP

Form fields, not JSON; files go as uploads or public URLs. Text models answer on the streaming route.

```
curl -X POST https://api.flymy.ai/api/v1/flymyai/kimi-k3_1-pro/predict/stream/ \
  -H "X-API-KEY: $FLYMYAI_API_KEY" \
  -F 'prompt=Explain in two sentences what an MCP server is.'
```

### With the OpenAI SDK

Kimi K3.1 Pro also answers the OpenAI Chat Completions protocol.

```
from openai import OpenAI

client = OpenAI(base_url="https://api.flymy.ai/api/v1/flymyai/kimi-k3_1-pro/openai/v1", api_key="YOUR_FLYMYAI_KEY")
reply = client.chat.completions.create(
    model="flymyai/kimi-k3_1-pro",
    messages=[{"role": "user", "content": "Explain in two sentences what an MCP server is."}],
)
print(reply.choices[0].message.content)
```
