Claude 3 Opus has an issue – Repeats same response over and over

I am using the API version of Claude 3 Opus to simulate patient profiles. I've been trying since the model got released and I keep getting the same patient description even with different combinations temperature, top_k, etc. I assumed it was a launch issue and it would eventually get fixed, but that did not happen. Is anyone else seeing the same issue ?

```import anthropic

client = anthropic.Anthropic( # defaults to os.environ.get("ANTHROPIC_API_KEY") api_key=os.environ["ANTHROPIC_API_KEY"] # Save ANTHROPIC_API_KEY in .env )

def create_anthropic_message(system_prompt, user_prompt, anthropic_model = "claude-3-opus-20240229", max_tokens = 200, temperature = 0.999, *kwargs): message = client.messages.create( model=anthropic_model, max_tokens=max_tokens, temperature=temperature, system=system_prompt, # Also include any other arguments in the def function kwargs *kwargs, messages=[{"role": "user","content": [{"type": "text","text": user_prompt}]}]) return (message)

# Run

for i in range(20): try: r = create_anthropic_message("You are an oncology expert","Compose a brief 1-sentence presentation of a US-based patient presenting with Skin Cancer.") print(r.content[0]) except Exception as error: # handle the exception print("An exception occurred:", error)```
