Function calling resets the conversational state in Responses API

API Bugs

Hi openai team,
i have noticed that the function calling resets the conversational state using the responses api. Is there anyway to maintain the conversational context?
I tried using the previous_response_id param but it gave a Bad request error.
Sample data can be found below
This image shows a spreadsheet with columns for response ID, previous response ID, timestamp, indent level, message input, and message output, containing sample chat log data. (Captioned by AI)

Thanks and regards,
Shreyas

Could you share an example of your code?

I just tried and it seems to work fine:

import requests
from openai import OpenAI
import json

client = OpenAI()
select_model="gpt-4.1-mini"

def get_weather(latitude, longitude):
    response = requests.get(f"https://api.open-meteo.com/v1/forecast?latitude={latitude}&longitude={longitude}&current=temperature_2m,wind_speed_10m&hourly=temperature_2m,relative_humidity_2m,wind_speed_10m")
    data = response.json()
    return data['current']['temperature_2m']

tools = [{
    "type": "function",
    "name": "get_weather",
    "description": "Get current temperature for provided coordinates in celsius.",
    "parameters": {
        "type": "object",
        "properties": {
            "latitude": {"type": "number"},
            "longitude": {"type": "number"}
        },
        "required": ["latitude", "longitude"],
        "additionalProperties": False
    },
    "strict": True
}]

input_messages = [{"role": "user", "content": "What's the weather like in Paris today?"}]

response = client.responses.create(
    model=select_model,
    input=input_messages,
    tools=tools,
)

print("id: ",response.id, "output:", response.output)


tool_call = response.output[0]
args = json.loads(tool_call.arguments)

result = get_weather(args["latitude"], args["longitude"])
print("get_weather returned: ", result)

input_messages = [{
    "type": "function_call_output",
    "call_id": tool_call.call_id,
    "output": str(result)
}]
response_2 = client.responses.create(
    model=select_model,
    previous_response_id=response.id,
    input=input_messages,
    #tools=tools,
)
print(response_2.output_text)

Thanks! Was able to get it to work after some troubleshooting.
