Do not retry: fix it firstRECITATION
What it meansThe request succeeded but the answer was stopped because it resembled existing text (for example song lyrics or book passages).
How to fix it
- Make the prompt or context more specific to your own content, and try a higher temperature.
Handle it in code
import random, time
from google import genai
from google.genai import errors
client = genai.Client()
def generate(prompt, tries=6):
for i in range(tries):
try:
return client.models.generate_content(model="gemini-flash-latest", contents=prompt)
except errors.APIError as e:
# 429 RESOURCE_EXHAUSTED, 503 UNAVAILABLE, 500, 504: transient. 400/402/403: fix, do not retry.
if e.code not in (429, 500, 503, 504) or i == tries - 1:
raise
time.sleep(min(60, 2 ** i) + random.random()) # exponential backoff + jitterGoogle lists 429 RESOURCE_EXHAUSTED, 503 UNAVAILABLE, 408 and 5xx as transient: retry with exponential backoff and jitter. 400, 402 and 403 are not.
