In February 2025, DeepSeek Open Infra – a small but ambitious team pushing the boundaries of artificial general intelligence (AGI) – hosted a groundbreaking Open-Source Week. Over five consecutive days, they released five production-ready AI tools, each designed to democratise access to high-performance infrastructure and fuel collaborative progress in AI development. Here’s what you need to know about this milestone event.
DeepSeek’s initiative isn’t about grandstanding; it’s a sincere effort to share battle-tested, open-source AI infrastructure with the global community. By open-sourcing tools that power their own AGI research, DeepSeek aims to accelerate innovation through collective momentum, reduce barriers for developers and researchers, and promote transparency in AI development. As the team stated: “No ivory towers – just pure garage-energy and community-driven innovation.”
Here’s a breakdown of the tools unveiled during the week, each optimised for modern hardware like NVIDIA’s Hopper GPUs:
Day 1: FlashMLA
This high-speed decoding kernel for AI models achieves 580 TFLOPS on H800 GPUs, making it ideal for handling variable-length sequences in real-time applications like chatbots.
Day 2: DeepEP
As the first open-source library for efficient MoE (Mixture of Experts) model training, DeepEP slashes communication overhead in distributed AI systems with support for FP8 and RDMA networks.
Day 3: DeepGEMM
A lightweight FP8 matrix multiplication library hitting 1,350+ TFLOPS on Hopper GPUs, DeepGEMM simplifies complex computations for both dense and MoE models.
Day 4: Parallelism Strategies
Key tools include DualPipe (boosting training speed via bidirectional pipeline parallelism) and EPLB (balancing workloads in expert-parallel systems).
Day 5: 3FS (Fire-Flyer File System)
This lightning-fast parallel file system delivers 6.6 TiB/s read speeds in large clusters, streamlining data-heavy tasks like training dataset loading and checkpoint management.
DeepSeek’s Open Week wasn’t just about code – it was a statement. By sharing tools like their V3/R1 inference system (achieving 73,700 input tokens per second per GPU node), they’re proving that open collaboration can coexist with commercial success. Notably, their systems report a 545% cost profit margin, demonstrating that efficiency and transparency aren’t mutually exclusive.
Looking ahead, DeepSeek’s releases set a new standard for community-driven AI development. As more teams adopt these tools, we could see faster iteration cycles for AI models, reduced costs for training and inference, and stronger benchmarks for transparent AGI research.

DeepSeek Open Week 2025 isn’t just a win for developers – it’s a blueprint for how open-source AI infrastructure can bridge the gap between cutting-edge research and real-world impact. As the team says: “Let’s geek out in the open together.”
