v3 repetitive function call ?

[smallufo]

This is my function call (simulate weather service)

request

{
    "messages": [
        {
            "role": "user",
            "content": "What's the weather like today in New York?"
        }
    ],
    "model": "deepseek-chat",
    "stream": false,
    "temperature": 1.0,
    "top_p": 1.0,
    "tools": [
        {
            "type": "function",
            "function": {

                            "description": "The city and state, e.g. San Francisco, CA"
                        },
                        "format": {
                            "type": "string",
                            "description": "The temperature unit to use. C for Celsius, F for Fahrenheit"
                        }
                    },
                    "required": [
                        "location",
                        "format"
                    ]
                }
            }
        }
    ]
}

deepseek reply (with funCall request)

                  }

And I reply :

        {
            "role": "user",

                    "type": "function",
                    "function": {
                        "name": "get_current_weather",

                    }
                }
            ]
        },
        {

    ],
    "model": "deepseek-chat",
    "stream": false,
    "temperature": 1.0,
    "top_p": 1.0,
    "tools": [
        {
            "type": "function",
            "function": {

                        "location": {

                            "description": "The city and state, e.g. San Francisco, CA"
                        },
                        "format": {
                            "type": "string",
                            "description": "The temperature unit to use. C for Celsius, F for Fahrenheit"
                        }
                    },
                    "required": [
                        "location",
                        "format"
                    ]
                }
            }
        }
    ]
}

BUT deepseek asks again !!! Instead of summarize the weather data.

{
   "id":"8040b2c7-0936-43d6-a290-a6e2d23932eb",
   "object":"chat.completion",
   "created":1735311016,
   "model":"deepseek-chat",
   "choices":[
      {
         "index":0,
         "message":{
            "role":"assistant",
            "content":"",
            "tool_calls":[
               {
                  "index":0,
                  "id":"call_0_6b19ba9e-cabb-4a69-bf35-9170f1143abb",
                  "type":"function",
                  "function":{
                     "name":"get_current_weather",
                     "arguments":"{\"location\":\"New York\",\"format\":\"F\"}"
                  }
               }
            ]
         },
         "logprobs":null,
         "finish_reason":"tool_calls"
      }
   ],
   "usage":{
      "prompt_tokens":175,
      "completion_tokens":25,
      "total_tokens":200,
      "prompt_cache_hit_tokens":128,
      "prompt_cache_miss_tokens":47
   },
   "system_fingerprint":"fp_f1afce2943"
}

This situation won't occur on OpenAI's function calling.
Is there anything wrong ?

Thanks.

I also encountered this issue when calling it in lobechat, where the function kept being called repeatedly

Please improve support for tool calls, preferably openai's beta.chat.completions.parse, which is critical for agent-related uses.
