Failed to get a response from the model after multiple attem
Error message
Failed to get a response from the model after multiple attempts.
What it means
The retrying LLM-callable in utils.py wraps model invocation with exponential backoff. After exhausting all attempts (every attempt raised an exception), it logs 'critical' and raises a generic Exception: no response could be obtained from the model.

Solutions
- Check the underlying logs/errors printed for each attempt: they reveal the root cause (auth, quota, network, bad model name).
- Fix credentials/rate limits: verify the API key env var and provider quota, or reduce request frequency.
- Increase max_retries/backoff for transient outages, and add a circuit breaker or fallback model so the pipeline can continue.
Example fix
# before
result = llm_callable(prompt) # raises after retries
# after
try:
result = llm_callable(prompt)
except Exception:
result = fallback_llm_callable(prompt) # secondary provider/model Defensive patterns
Strategy: retry
Validate before calling
import os
assert os.environ.get('OPENAI_API_KEY'), 'missing OPENAI_API_KEY' # adjust per provider Try / catch
try:
result = llm_callable(prompt)
except Exception as e:
if 'Failed to get a response' in str(e):
logger.error('LLM unavailable, using fallback')
result = fallback_llm_callable(prompt)
else:
raise Prevention
- Surface per-attempt errors in logs so the root cause (auth/quota/network) is visible.
- Configure a fallback model/provider and a circuit breaker for long automation runs.
- Check API key env vars and quota before starting bulk jobs.
When it happens
Trigger: Persistent LLM API failures across all retries: invalid/missing API key, rate limiting that outlasts the backoff window, network outage, or the provider being down.
Common situations: Expired or wrong OPENAI_API_KEY / provider credentials, quota exhausted, flaky network in CI, or a model name that the API rejects on every call.
