BenchLM tracks Exaone 4.0 1.2B as a regional Korea model. Its benchmark rows are published for direct inspection, but it is intentionally excluded from the public global leaderboard so local-market scores do not skew worldwide rankings.

Exaone 4.0 1.2B is a open weight model with a 128K token context window. It processes queries without explicit chain-of-thought reasoning, offering faster response times and lower token usage.

Exaone 4.0 1.2B sits inside the Exaone 4.0 family alongside Exaone 4.0 32B. This profile currently has 11 of 323 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.

Peer position

Exact provisional scores and ranks for the closest listed peers. A score can appear before a model clears the evidence threshold for a rank, so equal scores can have different rank states.
