Ling 3.1 Flash

by InclusionAI

Released 20 days after Ling-3.0-flash-Fin · All InclusionAI releases

Ling 3.1 Flash is inclusionAI's upgrade of Ling 3.0 Flash, a native hybrid reasoning model with 560B total parameters and 25B active per token. Its hybrid-linear architecture stacks 63 KDA layers and 9 gated MLA layers (a 7:1 ratio) over 512 routed experts, of which 8 fire per token beside one shared expert. inclusionAI aims it at real-world work: general-purpose agents, search, office productivity and software engineering, with results reported on Terminal-Bench 4.0, SWE-bench Pro, FrontierSWE and GDPVal-AA V2.1 and gains in finance and materials science. Thinking is switched on or off per request, and the model card describes a 1M-token context window. The weights are released in FP8 under the MIT license.
