BenchLM is tracking ZAYA1-8B, but this profile is currently excluded from the public leaderboard because it still lacks enough non-generated benchmark coverage to rank safely. Only non-generated public benchmark rows appear below.

ZAYA1-8B is a open weight model with a 131K token context window. It uses explicit chain-of-thought reasoning, which typically improves performance on math and complex reasoning tasks at the cost of higher latency and token usage.

ZAYA1-8B sits inside the ZAYA1 family alongside ZAYA1-74B-Preview. This profile currently has 11 of 225 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.

Its strongest category is Instruction Following (#85). This performance profile makes it a well-rounded choice across a range of tasks.
