No content response from any provider.

Error message

No content response from any provider. 

What it means

RetryNoProviderError raised by raise_exceptions when the exceptions dict is empty after a retry run: providers were tried, none raised, but no content chunk was ever yielded (started stayed False). It distinguishes 'failed with errors' from 'succeeded silently with nothing' — e.g. providers returned only empty deltas or none at all.

Solutions

1. Update g4f — empty-stream behavior often follows upstream markup changes that later releases fix.
2. Try a different model on the same chain to see whether the model specifically returns empty.
3. Enable debug logging to inspect which providers ran and what raw chunks (if any) arrived.
4. Retry once — transient empty responses occur; if persistent, pin the chain to a provider known to return content.

Example fix

// before
result = await g4f.ChatCompletion.create_async(model=model, messages=messages)

// after
from g4f.errors import RetryNoProviderError
try:
    result = await g4f.ChatCompletion.create_async(model=model, messages=messages)
except RetryNoProviderError:
    result = await g4f.ChatCompletion.create_async(model='gpt-4o-mini', messages=messages)

def is_empty_response_error(e: BaseException) -> bool:
    from g4f.errors import RetryNoProviderError
    return isinstance(e, RetryNoProviderError) and 'No content response' in str(e)

from g4f.errors import RetryNoProviderError
try:
    result = await g4f.ChatCompletion.create_async(model, messages)
except RetryNoProviderError as e:
    if 'No content response' in str(e):
        result = await g4f.ChatCompletion.create_async(model, messages)  # one retry: often transient
    else:
        raise

When it happens

Trigger: A RetryProvider completes its loop where each provider's generator finishes without yielding any is_content chunk — empty responses, whitespace-only deltas, or providers that return instantly without streaming content.

Common situations: Upstream A/B changes returning empty bodies; providers whose anti-bot layer returns an empty stream instead of an error; models that emit only empty reasoning chunks; version mismatches where chunk parsing yields nothing.
