Overview

AISummary of 3 articles

vLLM and SGLang both announce Day-0 support for Ling-3.1-flash, an open-source model from Ant Ling with about 560B total parameters, about 25B active per token, and up to 1M context. vLLM says users can serve the model on their own infrastructure.

SGLang says MXFP4 and block-FP8 quantization cut the weights from about 534GB to about 292GB, which it says fits on 4 Hopper GPUs.

SGLang also cites results on GDPVal-AA, FrontierSWE, and Terminal-Bench 4.0 for agent, office, and coding tasks. These results are not independently verified in the reports. Ant Ling thanks both projects and says their work gives developers more ways to deploy and tune Ling models.

    SGLang adds Day-0 support for Ling-3.1-flash, a 560B MoE model

    AISGLang announces Day-0 support for Ling-3.1-flash from AntLingAGI, a 560B-parameter MoE hybrid reasoning model with 25B active parameters and 1M context. MXFP4 and block-FP8 quantization reduce the weights from about 534GB to about 292GB, which the post says fits on 4 Hopper GPUs. The post also cites strong results on GDPVal-AA, FrontierSWE, and Terminal-Bench 4.0 for agent, office, and coding tasks.

    vLLM adds Day-0 support for Ling-3.1-flash, a 560B open-source model

    AIvLLM announces Day-0 support for Ling-3.1-flash, which has about 560B total parameters, about 25B active per token, and up to 1M context. The model turns a rough brief into web pages, mobile UIs, and interactive prototypes, and users can serve it on their own infrastructure with vLLM. Ant Ling (@AntLingAGI) released the model as open source.
