No Model Requests • AI Agent SDK

</div>

This function is defined in the guard module.

Block real model requests for the duration of the `with` block.

Composes with a suite-wide :func:allow_model_requests call and with other `no_model_requests` blocks. Rather than saving and restoring the global flag — which lets an inner or cross-thread scope exiting first re-enable requests while an outer scope is still open — this increments a block counter, so requests stay blocked until every open scope has exited::

with no_model_requests(): agent.start(“hello”) # raises ModelRequestBlocked
