What Is Google Gemini 3.5 — And Why It Matters
Let’s start here.
Google just released Gemini 3 Pro and Gemini 3 Flash — but behind the scenes, they’re already testing the next version: Google Gemini 3.5.
This isn’t hype. It’s happening right now on Google’s internal testing platform, LM Marina.
Leaked reports show that two models — code-named Fierce Falcon and Ghost Falcon — are part of the Gemini 3.5 family.
And the results are wild.
These models can write full games from scratch, generate complex applications in a single prompt, and solve reasoning problems that other AIs completely miss.
Gemini 3.5 isn’t just faster. It’s smarter, more efficient, and designed to think rather than just respond.
A Quick Recap: Gemini 3’s Foundation
Before diving into the 3.5 leaks, it helps to understand how far Gemini 3 has already come.
Google released Gemini 3 Pro on November 18, 2025, and followed it with Gemini 3 Flash on December 19.
Those two releases changed the entire landscape of AI development.
Here’s why:
-
Gemini 3 Flash scored 90.4% on GPQA Diamond — a PhD-level reasoning benchmark.
-
It also achieved 33.7% on Humanity’s Last Exam — without tools or plugins.
-
It runs 3x faster and uses 30% fewer tokens than the older Gemini 2.5 Pro model.
That means higher performance, lower cost, and faster results.
For developers, Gemini 3 Flash scored 78% on S-Bench verified — the gold standard for AI coding models.
It even beat Gemini 3 Pro in coding performance, which is why so many companies — from JetBrains to Bridgewater Associates — are already deploying it in production.
Gemini 3 Flash: What You Can Use Today
Gemini 3 Flash isn’t some experimental beta.
It’s live and ready inside Google AI Studio and the Gemini app.
You can use it right now — free — without a waiting list.
For developers, it’s like having a co-pilot that actually understands structure, syntax, and optimization.
For businesses, it’s an instant productivity tool.
It can summarize 1,000-page reports, analyze massive knowledge bases, or debug complex codebases — all with near-perfect accuracy.
And for creators? It’s fast enough to build full interactive experiences — websites, videos, scripts — in minutes.
But here’s the wild part.
While everyone’s still catching up to Gemini 3 Flash, Google has already moved on to something even more advanced.
Introducing Google Gemini 3.5 (Leaked Code Name: Snow Bunny)
According to leaked data from late December and early January, Google is already deep into testing Gemini 3.5.
The internal code name? Snow Bunny.
And it’s running under two test models:
-
Fierce Falcon — built for precision, logic, and coding.
-
Ghost Falcon — built for creativity, visuals, and design.
These models appeared on LM Marina, Google’s internal benchmark and ranking platform.
Developers and testers who spotted them noticed major jumps in reasoning, speed, and complexity handling.
Fierce Falcon produces clean, functional code with almost zero bugs.
Ghost Falcon can design entire UI systems, generate SVG graphics, and even compose original music.
This isn’t small progress — this is a complete leap forward.
How Google Is Testing Gemini 3.5
Google uses LM Marina to test AI models in the wild — with real user feedback.
That means the ranking data isn’t just from benchmarks; it’s from people actually interacting with the models.
When a model like Snow Bunny performs well there, it’s a strong indicator that it’s almost ready for public release.
Leaks suggest Google is planning to roll out Gemini 3.5 publicly by February 2026 — possibly sooner if testing continues at the current pace.
If you’re paying attention, this means one thing:
We’re just weeks away from the most capable AI model Google has ever built.
Fierce Falcon: The Developer’s Dream
Fierce Falcon is the technical powerhouse in the Gemini 3.5 lineup.
It’s optimized for speed, precision, and large-scale code generation.
Early tests show it can produce 3,000 lines of functional code from a single prompt — clean, organized, and ready to deploy.
No hallucinated functions. No broken logic.
It builds complete systems.
Imagine saying: “Build me a CRM app with user authentication, analytics dashboard, and export tools.”
And within minutes, you have a working prototype — with documentation.
That’s what Fierce Falcon does.
This is why developers are calling it “the coding model that feels human.”
Ghost Falcon: The Creative Engine
If Fierce Falcon is all logic, Ghost Falcon is all imagination.
It’s designed for creative work — UI/UX, generative art, design layouts, music, and motion.
In testing, Ghost Falcon generated SVG-based cyberpunk artwork with perfect layering and geometry.
It also produced music compositions that rivaled specialized audio models — dynamic, structured, and emotionally consistent.
However, testers noted that Ghost Falcon sometimes struggles with coherence in long sequences — which is likely why it’s still in testing.
Once stable, it could redefine how creators work with visual and audio AI tools.
Gemini 3.5 Performance Benchmarks
Leaked benchmark results show Gemini 3.5 performing beyond what anyone expected.
-
Hieroglyphic Benchmark (Reasoning): 80% — higher than GPT-5 and Claude 4 Opus.
-
S-Bench Verified (Coding): Expected 82–85%.
-
Response Efficiency: 30–40% faster than Gemini 3 Flash.
-
Context Window: Expected expansion beyond 1 million tokens.
That last one is huge.
A larger context window means Gemini 3.5 can handle massive projects — entire documentation sets, product roadmaps, or 100-page conversations — without losing track.
It can literally read and reason across thousands of connected documents at once.
Gemini 3.5’s New Features
Two new features are rumored to define Gemini 3.5:
-
DeepThink Mode — for long-form reasoning, planning, and analysis. Perfect for research, logic puzzles, and architecture.
-
Flash Mode — near-instant response generation for fast iteration and creative exploration.
This dual-mode system balances deep intelligence with speed — giving users the best of both worlds.
DeepThink solves complex problems like a strategist.
Flash executes like a creative machine.
Together, they form the backbone of a model that can think, create, and deliver — all in one session.

Pricing and Accessibility
One of the reasons Gemini 3 Flash exploded in popularity is cost.
It runs at just $0.50 per million input tokens and $3 per million output tokens — dirt cheap for enterprise-level performance.
If Gemini 3.5 keeps similar pricing, it’s going to undercut almost every major competitor in the AI space.
Expect Gemini 3.5 to appear first inside Google AI Studio and Gemini Advanced, then expand through the API and workspace integrations.
How This Impacts the AI Race
Make no mistake — Google Gemini 3.5 isn’t being developed in isolation.
This is part of the bigger AI race.
Google is moving aggressively to compete with OpenAI’s GPT-5.2 and Anthropic’s Claude 4 Opus.
But while others focus on cloud-based systems, Google’s leaning into hybrid intelligence — part local, part cloud.
That’s what makes Gemini unique.
It’s built to run lightweight enough for local devices but powerful enough for enterprise-scale AI.
That combination could make it the most balanced and practical AI ecosystem on the market.
What’s Next for Google Gemini 3.5
Based on testing intensity and rollout timelines, Gemini 3.5 is likely to be announced by early February 2026.
Expect:
-
Faster reasoning and planning.
-
Extended context windows.
-
More integration with Google Workspace.
-
Cross-model collaboration (where different Falcons handle different parts of a single task).
Imagine asking Gemini to design a marketing funnel — and it instantly assigns parts of the task to different internal agents that handle design, copywriting, analytics, and automation.
That’s where this is heading.
And once Gemini 4 arrives later this year, these capabilities will only multiply.
