Coverage detailsHow much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

Benchmark ledger
Agentic opens by default. The marker compares each value with the best source-verified result in the catalog; provisional leaders do not set the reference. Expand the remaining categories for every published row.

All 2 rowsLineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Fugu Cyber, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Fugu Cyber is a proprietary model with a 1M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
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.
Official exact-value snapshot from Sakana AI's July 21, 2026 Fugu Cyber launch page. We store CyberGym and CTI-REALM as display-only cybersecurity results because neither benchmark is part of the weighted schema.
Fugu Cyber sits in the Sakana Fugu family with Sakana Fugu, Sakana Fugu-Ultra, Sakana Fugu-Ultra v1.1. 2 of 495 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated September 30, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does Fugu Cyber perform overall in AI benchmarks?
Fugu Cyber has 2 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is Fugu Cyber good for agentic tool use and computer tasks?
Fugu Cyber has source-displayable benchmark coverage for agentic tool use and computer tasks, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Which sibling models are related to Fugu Cyber?
Fugu Cyber belongs to the Sakana Fugu family. Related tracked variants include Sakana Fugu, Sakana Fugu-Ultra, Sakana Fugu-Ultra v1.1. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Fugu Cyber have full benchmark coverage on BenchLM?
No. Fugu Cyber currently has 2 source-displayable rows across 495 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Fugu Cyber?
Fugu Cyber has a reported context window of 1M in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
