My role & implementation
Fine-tuned the vision-language model with LoRA and optimized inference using FP8 quantization and Flash Attention 2. Deployed model serving through vLLM on one NVIDIA L40S GPU.
Reported scale
30,000 daily active users and 1–2K peak requests per second are platform-wide figures. They describe platform traffic, not GPU inference throughput.
