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)“`
