Open SourceLong context

K2 Think V2 has model metadata, but missing tracked provider pricing keeps it from being a default production pick.

Decision context: Long context task fit, 0 tracked provider routes, and research from 2026-05-19.

Use it for

  • Teams evaluating long context
  • Workloads that can use a 512k context window

Do not use it for

  • Cost-sensitive launches that need sourced token pricing
  • Vision or document-understanding workloads
  • Strict JSON or tool-calling flows

About

K2 Think V2 is a 70B parameter open-source reasoning model from MBZUAI (Mohamed bin Zayed University of Artificial Intelligence), developed in collaboration with G42 and Cerebras Systems. Built on the K2-V2 base model, it is optimized for deep multi-step reasoning across math, science, coding, logic, and long-context tasks with a 512K token context window. Released under a '360-open' approach including weights, training code, data, and evaluation tools.

K2 Think V2 is an open-source model in the K2 Think family. The structured metadata tracks a 512k-token context window. Headline tracked benchmarks include Google-Proof Q&A 71.3.

Benchmark Scores(1)

Scores are benchmark-specific and are direction-aware: the same numeric gap can mean very different outcomes across suites. Use the leaderboard context and this model's provider route to decide whether the winning margin is meaningful for your workload.
