AI API receipt · sgl-project/sglang

Inkling "reasoning off" is ignored, so a request that disabled thinking is processed with reasoning on

sgl-project/sglang#43145 · upstream bug reproduced by running the issue's own reproduction

Badgr cannot tell this response is wrong

The request set reasoning off; the server still produced a reasoning-style answer.

the reply is well-formed text; Badgr cannot tell whether reasoning was enabled behind it. The receipt therefore records success. This is a limit of what the contract can prove, shown here so it is not mistaken for protection.

What the upstream returned (replayed)

The output the bug produces, taken from the issue’s reproduction and fed to Badgr’s validators. Not a live provider call.

text: "Let me think step by step. 2 + 2 = 4. The answer is 4."
