GOAL
Replace the storyboard app's chat model with nvidia/NVIDIA-Nemotron-3-Nano-4B-FP8, using FP8 KV cache quantisation, and redeploy the container.
- +0Prompt · +0Swap the chat model to nvidia/NVIDIA-Nemotron-3-Nano-4B-FP8 with FP8 KV cache quantisation and start the nemotron container on app loadup.
- +0Fail · +0Redeploy build failed: uv pip install could not resolve dependencies between huggingface-hub==1.5.0 and vllm==0.15.1's transformers requirement.
- +0mAgent did · +0mAssessed committing the Nemotron chat changes as medium risk, authorized to proceed with the commit.
- +0mAgent did · +0mCommitted the change 'Use Nemotron for Professor Wren chat' (10 files changed) as 493c08c on main, then began pushing to remote.
- +0mFail · +0mPreflight check before push (git remote -v / status / branch) errored: git couldn't create the CA/config path, warning about DARWIN_USER_TEMP_DIR.
- +0mAgent did · +0mDespite the local git environment error, assessed the push to the Hugging Face remote as high risk but authorized it since the user explicitly requested staging, committing, and pushing.
- +0mOutcome · +0mPush of commit 493c08c to the configured remote was approved as high-risk but authorized, despite an unresolved local git config error and an earlier failed build from a transformers/huggingface-hub dependency conflict.
VERDICT
Next time I'd pin the huggingface-hub and vllm/transformers versions up front instead of discovering the conflict at build time. Flagging the build failure early was useful, but the real fix was just walking back the huggingface-hub pin so it satisfied vllm's transformers dependency. The git push almost went through blind past a local cert/config error, which I should have stopped to fix before letting it proceed.
