Model is speaking differently in the web ui compared to the API

[gdet]

Hello everyone,
I have loaded a local model and it is working very well in the chat tab but when I am using the API it is not speaking so good.
I tried to pass as many arguments that I found but still there are issues.

 payload = {
    "messages": history,  # The user's input with the history
    "mode": "chat-instruct", 
    "character": "Assistant",
    "greeting": "Hello. I would like to ask you some questions",
    "max_new_tokens": 512,  # Adjust as necessary     # Adjust as necessary
    "stop": ["\n"],         # Define the stop tokens as needed
    "do_sample": True,      # Set to False for deterministic outpu       
    "temperature": 0.85,
    'top_p': 1,
    "top_k":0,
    'typical_p': 1,
    'min_p':0.05,
    'repetition_penalty': 1.01,
    'encoder_repetition_penalty': 1,
    'presence_penalty':0,
    'frequency_penalty':0,
    'repetition_penalty_range':1024,
    'top_k': 50,
    'min_length': 0,
    'no_repeat_ngram_size': 0,
    'num_beams': 1,
    'penalty_alpha': 0,
    'length_penalty': 1,
    'early_stopping': False,
    'seed': -1,
    'add_bos_token': True,
    'truncation_length': 2048,
    'ban_eos_token': False,
    'attn_implementation':'eager',
    'torch_dtype':'bf16',
     "seed": 42
}

I also added the same chat_instruct_command but it does not improve.Also greeting is not working. Sometimes it is ok and sometimes it is not ok at all.
What else can I do? Am I missing something?
In model tab there is eager_attention enabled and bf16 but I do not know how to pass them as parameters.
Thank you

Set the WebUI to verbose mode, and look at the parameters it outputs in the console, see if there's anything there different from what you're using in your API call.
