Core Viewpoint - The introduction of the UE8M0 FP8 format and the next-generation domestic chips signifies a major advancement in the Chinese AI industry, indicating a shift towards hardware-software synergy and reduced reliance on foreign computing power [1][36]. Group 1: Market Reaction - Domestic chip companies' stock prices surged, with Cambrian Technology rising nearly 14% and hitting the daily limit, becoming the top company on the STAR Market [2][35]. - The semiconductor ETF also experienced a significant increase of 5.89% within half a day [5]. Group 2: Technical Explanation of UE8M0 FP8 - UE8M0 FP8 is based on the MXFP8 format, which was defined in the Open Compute Project's 2023 specification, allowing for an 8-bit micro-scaling block format [10][11]. - The MXFP8 format allows for block-level scaling, which retains the 8-bit width while expanding the dynamic range significantly [14][22]. - The UE8M0 format specifically uses an all-exponent representation for scaling factors, which simplifies processing and reduces computational overhead [22][23]. Group 3: Implications for Domestic Chips - Most existing domestic AI accelerators still use FP16/BF16 + INT8 pathways, but new chips like MUSA 3.1 GPU and VIP9000 NPU are beginning to support native FP8 [26]. - The UE8M0 format can save 75% of bandwidth compared to traditional FP32 scaling, making it a crucial optimization for next-generation architectures [27]. - The support for UE8M0 FP8 by various domestic chip manufacturers indicates a significant competitive advantage and potential for improved performance in AI applications [36][37]. Group 4: Industry Collaboration - DeepSeek has collaborated with 15 manufacturers to validate the UE8M0 format, with several companies already adapting their products to support this new standard [26][29]. - The collaboration between DeepSeek and domestic chip manufacturers is likened to the historical Wintel alliance, suggesting a strong ecosystem is being built around these technologies [37].
