LLM Calling Skill

List available models and send chat requests to any of them without extra configuration.

Core Capabilities

• List currently available models
• Use the current Agent text model for requests
• Send chat completion requests in OpenAI format, non-streaming
• Attach images to vision-capable model requests

Usage Guide

When you need to call an LLM in code, use the SDK functions from sdk.llm. There are two supported execution paths:

• Use run_python_snippet to execute a short or medium code snippet directly.
• Write the code to a .py file, then execute it with shell_exec.

create_openai_sync_client is a Python SDK function, not a tool name. Import it inside your Python code.

By default, call create_openai_sync_client() with no arguments. This uses the current Super Magic OpenAI-compatible endpoint and credentials automatically.

To use a custom OpenAI-compatible provider, pass api_key and base_url explicitly. You can also pass OpenAI client options such as timeout, max_retries, default_headers, and any additional keyword arguments supported by the OpenAI SDK.

To use the current Agent text model, read the SUPER_MAGIC_CURRENT_MODEL_ID environment variable in the script. This variable is injected by run_python_snippet. If it is missing, list models first and choose an explicit model ID.

# Option 1: run_python_snippet
run_python_snippet(
    purpose="Run model code",
    python_code="""
import os
from sdk.llm import create_openai_sync_client

client = create_openai_sync_client()
model_id = os.environ.get("SUPER_MAGIC_CURRENT_MODEL_ID") or "<model-id>"
...
""",
    timeout=300,
)

# Option 2: write a .py file, then run it with shell_exec
# First write the script with write_file, then execute:
shell_exec("python scripts/my_llm_script.py")

LLM calls can take a while. Increase the timeout based on task complexity, for example timeout=120 for a single call and timeout=300 or more for multi-model comparisons or batch inference.

Client Configuration

Default Super Magic Provider

Use the no-argument form when you want the current Super Magic provider:

run_python_snippet(
    purpose="Send test prompt",
    python_code="""
import os
from sdk.llm import create_openai_sync_client

client = create_openai_sync_client()
model_id = os.environ.get("SUPER_MAGIC_CURRENT_MODEL_ID") or "<model-id>"

response = client.chat.completions.create(
    model=model_id,
    messages=[{"role": "user", "content": "Hello"}],
    extra_body={"thinking": {"type": "disabled"}},
)
print(response.choices[0].message.content)
""",
    timeout=120,
)

Custom OpenAI-Compatible Provider

Use explicit client arguments when the user provides their own OpenAI-compatible service:

run_python_snippet(
    purpose="Use custom model",
    python_code="""
import os
from sdk.llm import create_openai_sync_client

client = create_openai_sync_client(
    api_key=os.environ["CUSTOM_OPENAI_API_KEY"],
    base_url="https://api.example.com/v1",
    timeout=120,
    max_retries=1,
)

response = client.chat.completions.create(
    model="custom-model-id",
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)
""",
    timeout=180,
)

Quick Start

Step 1: List Available Models

When unsure of the model ID, query available models first:

run_python_snippet(
    purpose="List models",
    python_code="""
import json
from sdk.llm import create_openai_sync_client

client = create_openai_sync_client()
models = client.models.list()
print(json.dumps([{"id": m.id} for m in models.data], ensure_ascii=False, indent=2))
""",
)

Example output:

[
  {"id": "claude-3-5-sonnet-20241022"},
  {"id": "gpt-4o"},
  {"id": "deepseek-v3"}
]

Step 2: Send a Chat Request

Use a real model ID to send a chat request. When executed through run_python_snippet, you can read SUPER_MAGIC_CURRENT_MODEL_ID to use the current model:

run_python_snippet(
    purpose="Send chat",
    python_code="""
import os
from sdk.llm import create_openai_sync_client

client = create_openai_sync_client()
model_id = os.environ.get("SUPER_MAGIC_CURRENT_MODEL_ID") or "<model-id>"

response = client.chat.completions.create(
    model=model_id,
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Hello"},
    ],
    extra_body={"thinking": {"type": "disabled"}},
)

print(response.choices[0].message.content)
""",
    timeout=120,
)

Vision: Attach Images in Messages

When using a vision-capable model, images can be included in messages. The SDK provides two ways to convert a workspace file to a URL:

Both functions accept http and https URLs as input and return them unchanged.

Important: image_to_base64 already returns a complete data URL string, such as data:image/jpeg;base64,/9j/4AAQ.... Use the return value directly as the url field. Do not prepend data:image/jpeg;base64, again.

run_python_snippet(
    purpose="Analyze image",
    python_code="""
import os
from sdk.llm import create_openai_sync_client, file_to_url, image_to_base64

client = create_openai_sync_client()
model_id = os.environ.get("SUPER_MAGIC_CURRENT_MODEL_ID") or "<vision-model-id>"

# Use file_to_url first. Paths are relative to the .workspace directory.
image_url = file_to_url("test/screenshot.png")

# Fallback if file_to_url fails:
# image_url = image_to_base64("test/screenshot.png")
# image_to_base64 returns a complete data URL. Use it directly.

response = client.chat.completions.create(
    model=model_id,
    messages=[{
        "role": "user",
        "content": [
            {"type": "image_url", "image_url": {"url": image_url}},
            {"type": "text", "text": "Describe this image."},
        ],
    }],
    extra_body={"thinking": {"type": "disabled"}},
)

print(response.choices[0].message.content)
""",
    timeout=120,
)

Parameter Reference

Common Parameters for client.chat.completions.create()

thinking Parameter

Pass thinking via extra_body to control whether the model emits reasoning content. The recommended default is disabled to avoid unnecessary token usage and latency.

Note: The thinking parameter only applies to models that support it. Passing it to unsupported models may cause errors, so check the target model before using it.

# Disable thinking. Recommended default.
extra_body={"thinking": {"type": "disabled"}}

# Enable thinking.
extra_body={"thinking": {"type": "enabled"}}

# Let the model decide.
extra_body={"thinking": {"type": "auto"}}

Return Value

client.chat.completions.create() returns a ChatCompletion object:

response.choices[0].message.content
response.choices[0].message.tool_calls
response.choices[0].finish_reason
response.usage.total_tokens

# Only present when thinking.type is "enabled" or "auto" and the model emits reasoning content.
response.choices[0].message.reasoning_content
response.usage.completion_tokens_details

reasoning_content is a non-standard field and may not be parsed by the OpenAI SDK as a normal attribute. Access it as follows:

reasoning = response.choices[0].message.model_extra.get("reasoning_content")

import json
msg_dict = json.loads(response.choices[0].message.model_dump_json())
reasoning = msg_dict.get("reasoning_content")
