BenchLM is tracking Fugu Cyber, 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.
Fugu Cyber is a proprietary model with a 1M 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.
Available through Sakana AI's OpenAI-compatible API as fugu-cyber-v1.0. Access is limited to the Token Plan and requires an approved use-case application.
Fugu Cyber sits inside the Sakana Fugu family alongside Sakana Fugu, Sakana Fugu-Ultra. This profile currently has 2 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.
