Mid-May 2026 was supposed to be a calm interval after wrapping up our 2nd fine-tuning (fine_tuning_2). Instead, May 17th hit our team with a relentless double challenge: condensing hundreds of raw inference metrics into an automated technical report, while simultaneously battling a cryptic HTTP 401 Unauthorized cascading error across our newly integrated FastAPI and PostgreSQL backend.

Here is the complete post-mortem of how we automated our reporting and systematically neutralized the backend authentication breakdown.

On May 3, having gained enough experience with the 8B models, our team finally challenged the ultimate kings of performance: fine-tuning massive 70B (70 billion parameters) models. We attempted to train both Llama 3.3 70B and DeepSeek-R1 70B, but as expected, we hit a massive hardware resource wall.

On April 9, using the Colab notebook we ambitiously completed yesterday, we finally attempted the first training (fine-tuning) of our artificial intelligence model (Llama 3.1). However, reality was not that easy, and we had to face numerous errors. It was also a tough day as we had to simultaneously create the presentation materials for the 6th week of the Capstone Design project.
