Details

Ling-2.6-1T was released as a flagship model in the 1T parameter class, targeting code generation and everyday agentic workflows.

  • A hybrid of MLA + Linear Attention lowers latency and VRAM usage for long-context.
  • Contextual Process Redundancy Suppression in post-training reduces verbose CoT and applies 'fast thinking'.
  • It presented open-source SOTA-level results on AIME26, SWE-bench Verified, BFCL-V4, TAU2-Bench, IFBench, and emphasized long-context consistency with MRCR 16K-256K.
  • It presented an Artificial Analysis Intelligence Index of 34 and about 16 million output tokens.
  • SGLang and vLLM deployment examples and a 262,144-token context configuration were provided, and for MTP inference a patched branch was recommended due to an official SGLang bug.
  • It emphasized integration with Claude Code, OpenClaw, OpenCode, and CodeBuddy, targeting multi-tool agentic work.
