Increasing the global float16 tolerance to 1e-2 is a significant relaxation that could mask numerical regressions across the entire test suite. float16 typically supports a precision around 1e-3. A better approach to handle CI failures is to override the tolerance in specific test cases that exhibit instability on the NPU, rather than globally reducing the sensitivity of all tests.
