Decision reading
Gemini 3.8 Flash Cyber is tracked, but not publicly ranked yet. The profile exposes 2 sourced benchmark rows and leaves unsupported fields blank until a published record exists.

Data as of September 2, 2026 · How the score is built

Strongest published evidence

Published rows are visible, but no category has enough eligible evidence for a comparative rank.

Validate before choosing

2 published rows leave some tracked benchmark slots empty. No comparable first-party API token rate is published.

Decision snapshot

Each value carries a field reference instead of floating alone. Markers compare this model with the current ranked and priced catalog; they are not absolute quality thresholds.

How 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.

Lineage

The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. 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 Gemini 3.8 Flash Cyber, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.

Gemini 3.8 Flash Cyber is a proprietary model. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

Available by application to trusted government authorities, critical-infrastructure operators, and software maintainers through Google's Fairwind Program. Google has not published a standalone API model ID, context-window specification, or token price for this variant.

Official September 2, 2026 launch snapshot from Google's Gemini 3.8 Flash and Gemini 3.8 Flash Cyber announcement. Google reports 86.2% pass@1 on CyberGym for autonomous vulnerability discovery in C/C++ and 47.2% pass@1 on the external CWE-Bench automated-patching benchmark. Both rows remain display-only cybersecurity evidence. The launch chart's 77.5% comparison row for Gemini 3.5 Flash Cyber uses a different evaluation setup from the earlier CodeMender result stored on that model, so we do not overwrite the historical 83.2% row. Google's internal 20-language vulnerability benchmark, Chrome patch comparison, Wiz penetration-testing results, and prompt-injection claims remain outside scored fields because they are private, relative, or do not expose a reproducible public protocol.

Gemini 3.8 Flash Cyber sits in the Gemini 3.8 Flash family with Gemini 3.8 Flash. Its explicit predecessor is Gemini 3.5 Flash Cyber. 2 of 416 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Frequently asked questions

How does Gemini 3.8 Flash Cyber perform overall in AI benchmarks?

Gemini 3.8 Flash 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 Gemini 3.8 Flash Cyber good for agentic tool use and computer tasks?

Gemini 3.8 Flash 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 Gemini 3.8 Flash Cyber?

Gemini 3.8 Flash Cyber belongs to the Gemini 3.8 Flash family. Related tracked variants include Gemini 3.8 Flash. 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 Gemini 3.8 Flash Cyber have full benchmark coverage on BenchLM?

No. Gemini 3.8 Flash Cyber currently has 2 source-displayable rows across 416 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 Gemini 3.8 Flash Cyber?

Gemini 3.8 Flash Cyber's provider has not published a context-window limit for this exact model. The profile leaves the value unavailable instead of borrowing a number from an earlier family member or a third-party route. Maximum output length is tracked separately when the provider documents it.
