Ant Group's Ling team open-sources 560B Ling-3.1-flash
On October 15, Ant Group's Ling team released Ling-3.1-flash as open weights, publishing an FP8 checkpoint under the MIT license on Hugging Face and ModelScope. The model has about 560B total parameters and activates about 25B per token; Ant says it supports up to 1M context, though 36Kr notes the repository's max_position_embeddings is 262,144 and 1M is listed as a target, while Artificial Analysis measured an intelligence index of 41 and about 210 tokens per second. Ant says a mixed MXFP4/block-FP8 scheme cuts weights from about 534GB to 292GB and its Hopper test configuration from eight GPUs to four; 36Kr also notes vendor benchmark scores were run on the unreleased LingCode harness, and independent testing found flaws in long-chain agent tasks.
According to the vendor, the open-weight release lets teams with server-class GPUs run a roughly 560B-parameter model on fewer cards, while 36Kr cautions that the four-GPU figure comes from a specific test configuration and is not a procurement checklist.
