Prerequisites

Before diving into the integration of Qwen2-7B Cognitive Actions, make sure you have the following:

• API Key: You will need an API key to authenticate your requests to the Cognitive Actions platform.
• Basic Setup: Familiarity with making HTTP requests in your programming language of choice, specifically for sending JSON payloads.

Authentication typically involves passing your API key in the headers of your HTTP requests, which allows for secure access to the actions.

Cognitive Actions Overview

Generate Chat Completion with Qwen2-7B

Description: This action generates chat completions using the Qwen2-7B-Instruct language model. It excels in creating contextually relevant and coherent text based on the input prompt provided.

Category: Text Generation

Input

Here’s a breakdown of the required and optional fields based on the input schema:

• prompt (string, required): An input text prompt guiding the model's generation.
  Example: "Tell me a joke about only having 7 billion parameters"
• modelType (string, required): Select the model variant to be used.
  Example: "Qwen2-7B-Instruct"
• topK (integer, optional): Samples from the top K most likely tokens when generating text.
  Default: 1
• topP (number, optional): Samples tokens from the top P percentage of the probability distribution.
  Default: 1
• temperature (number, optional): Controls the randomness of outputs. Higher values yield more randomness.
  Default: 1
• maxNewTokens (integer, optional): Maximum number of tokens allowed for generation.
  Default: 512
• systemPrompt (string, optional): A system-level prompt that sets the response style.
  Default: "You are a helpful assistant."
• repetitionPenalty (number, optional): Applies a penalty to repeated words to minimize redundancy.
  Default: 1

Example Input:

{
  "topK": 1,
  "topP": 1,
  "prompt": "Tell me a joke about only having 7 billion parameters",
  "modelType": "Qwen2-7B-Instruct",
  "temperature": 1,
  "maxNewTokens": 512,
  "systemPrompt": "You are a funny and helpful assistant.",
  "repetitionPenalty": 1
}

Output

The action returns a list of tokens that make up the generated text. Here’s a glimpse of a potential output:

Example Output:

[
  "",
  "Why ",
  "did ",
  "the ",
  "AI ",
  "only ",
  "have ",
  "",
  "7 ",
  "billion ",
  "parameters?\n\n",
  "",
  "Because ",
  "it ",

  "to ",
  "compress ",
  "itself ",
  "below ",
  "the ",
  "world ",
  "",
  "",
  "population!"
]

Conceptual Usage Example (Python)

The following Python snippet illustrates how to call the Cognitive Actions execution endpoint to generate a chat completion:

import requests
import json

# Replace with your Cognitive Actions API key and endpoint
COGNITIVE_ACTIONS_API_KEY = "YOUR_COGNITIVE_ACTIONS_API_KEY"
COGNITIVE_ACTIONS_EXECUTE_URL = "https://api.cognitiveactions.com/actions/execute" # Hypothetical endpoint

action_id = "588c2914-e9ff-4c2e-a649-66e3d615ccce" # Action ID for Generate Chat Completion with Qwen2-7B

# Construct the input payload based on the action's requirements
payload = {
    "topK": 1,
    "topP": 1,
    "prompt": "Tell me a joke about only having 7 billion parameters",
    "modelType": "Qwen2-7B-Instruct",
    "temperature": 1,
    "maxNewTokens": 512,
    "systemPrompt": "You are a funny and helpful assistant.",
    "repetitionPenalty": 1
}

headers = {
    "Authorization": f"Bearer {COGNITIVE_ACTIONS_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(
        COGNITIVE_ACTIONS_EXECUTE_URL,
        headers=headers,
        json={"action_id": action_id, "inputs": payload} # Hypothetical structure
    )
    response.raise_for_status() # Raise an exception for bad status codes (4xx or 5xx)

    result = response.json()
    print("Action executed successfully:")
    print(json.dumps(result, indent=2))

except requests.exceptions.RequestException as e:
    print(f"Error executing action {action_id}: {e}")
    if e.response is not None:
        print(f"Response status: {e.response.status_code}")
        try:
            print(f"Response body: {e.response.json()}")
        except json.JSONDecodeError:
            print(f"Response body: {e.response.text}")

In this code snippet:

• Replace YOUR_COGNITIVE_ACTIONS_API_KEY with your actual API key.
• The action_id corresponds to "Generate Chat Completion with Qwen2-7B".
• The payload is structured to match the expected input schema.
