What changed with Gemini 3
Gemini 3 arrived with expanded availability across Google’s AI platforms and new developer-facing agentic tools. You will find the model in Google’s AI Studio, the Gemini app, and Vertex AI. There are also tiered access rules: different Google AI plans unlock progressively deeper features, while a specialized DeepThink variant is being staged for safety testers and premium subscribers.
Under the hood, the changes are both architectural and practical. Gemini 3 raises the bar on persistent planning and long-horizon tasks. It also dramatically increases the token context to around one million tokens for input and provides up to 64k-token outputs. That combination lets the model reason across very long documents and ongoing tasks in a single session without losing track of the thread.
“This isn’t a tiny incremental update. It really does deserve the three at the end of it.”
Agentic tools: anti-gravity and beyond
Beyond raw model improvements, Google introduced an agentic development platform codenamed anti-gravity. This is a set of tools and integrations meant to let models execute tasks, call APIs, maintain state over time, and orchestrate services like Firebase and browser automation libraries. In practice, anti-gravity can help developers turn Gemini 3 from a super-smart assistant into a working autonomous component of a business workflow.
That means you can expect developers to build systems that monitor inventory, respond to customers, execute trades, or run support bots with minimal human supervision. The combination of improved long-term memory, reliable planning, and accessible agent tools is what makes this release noteworthy.
Benchmarks that matter
Benchmarks are imperfect, but they give a structured way to compare capabilities. Gemini 3 shows up at the top of a wide variety of demanding tests — especially those measuring agentic behavior, long-horizon planning, multimodal reasoning, and high‑stakes math and science problems.
Vending Bench 2: agentic simulation done right
Vending Bench 2 simulates an autonomous small business. Models start with seed capital and run a vending machine: order stock, respond to customer requests, manage prices, and keep the business profitable over hundreds of simulated days. It is a test of persistence, planning, negotiation with suppliers, and adapting to competition.
Gemini 3 Pro dramatically outperformed prior leaders. Where Gemini 2.5 Pro barely made a return on the initial capital, Gemini 3 Pro multiplied net worth more than tenfold in the same simulated period. The model consistently negotiated favorable wholesale terms, found trustworthy suppliers, and adjusted strategy over long time horizons. That kind of performance is a practical indicator for real-world agentic applications.
Arena and competition
When agents are placed in a shared location and must compete — the Arena variant — strategic behavior matters more. Gemini 3 Pro proved ruthless in competitive situations, maintaining positive ROI where many competitors fell into negative territory. In short, the model not only plans well but anticipates and outmaneuvers other agents.
Alpha Arena and financial trading
Early autonomous trading contests show promise for models that can react quickly, adapt to market conditions, and generalize across noisy data. Previous seasons showed only a few models outperforming the market. The next season will be an important test for Gemini 3’s live trading and market interaction capabilities.
Expert tests: math, science, and scholastic exams
Gemini 3 is not just an agentic champ. It also excels on some of the toughest human exams designed by domain experts.
- Humanity’s Last Exam — a difficult multimodal test covering advanced math and science — saw Gemini 3 at the top with a significant margin over the nearest rivals.
- GPQ-A Diamond — graduate-level multiple choice in physics, chemistry, and biology written by PhD-level experts — returned excellent scores for Gemini 3 Pro.
- AIME and Math Arena Apex — hardest contest-level math problems — showed Gemini 3 making far greater headway than other models. It achieved near-perfect results on certain math benchmarks when paired with code execution tools.
These outcomes matter because they measure domain reasoning, symbolic manipulation, and the ability to apply formal methods. That makes Gemini 3 attractive for scientific assistants, tutoring, code generation, and research workflows.
Multimodal and GUI understanding
Gemini 3 also stretches multimodal capabilities. On tests requiring visual comprehension, chart interpretation, GUI navigation, and lecture-video understanding, the model consistently outperformed the previous generation.
- Car-Cyve reasoning for chart comprehension showed large gains, making Gemini 3 strong at reading visual data and answering precise questions about it.
- ScreenSpot Pro assessed GUI target-finding in dense interfaces; Gemini 3’s leaps mean it can identify precise UI targets and act in automated GUI workflows more reliably.
- MMU Pro and video-based question sets demonstrated better lecture comprehension and multimodal synthesis.
Code, competitive programming, and terminal tasks
Developers will care about two things: how well the model writes code, and how well it performs in terminal-like, programmatic evaluations.
On competitive programming benchmarks like Lifecode Bench, Gemini 3 made notable improvements over recent top models, earning higher ratings and solving problems with better correctness. In terminal-emulation tasks and multi-step coding workflows, Gemini 3 performed strongly, showing more reliable code execution planning and debugging assistance. Early tests suggest a step change for coding assistant workflows.
Text, creative writing, and instruction following
Across text-based categories — from creative writing to long multi-turn instructions — Gemini 3 Pro offered strong performance without obvious weak spots. It topped leaderboards for instruction following and handled long dialogues and complex prompts better than previous models that struggled with long-horizon coherence.
Accuracy versus cost: intelligence per dollar
Benchmarks that compare accuracy to cost show Gemini 3 reshaping the curve. Gemini 3 Pro often sits in the sweet spot: high accuracy at a cost per task lower than some competitors. For teams balancing budget and capability, that makes it compelling.
For those who need peak accuracy regardless of cost, there is a DeepThink variant that yields even higher correctness on certain problems, at a significantly higher price. That tiered approach gives teams options: efficient, high-performing models for general workloads and specialist high-accuracy instances for critical tasks.
Practical takeaways for businesses
Canadian Technology Magazine readers running or advising businesses should consider the following practical implications:
- Agentic automation is closer to production: Benchmarks like Vending Bench 2 demonstrate models can manage inventory, supplier relationships, pricing, and customer interactions with sustained coherence.
- Long-context workflows become feasible: The million-token context window enables end-to-end processing of massive documents, long chat histories, or multi-day agent state without losing critical detail.
- Multimodal support reduces integration overhead: Stronger image, video, and GUI understanding means fewer external services are needed to interpret visual data.
- Coding assistants genuinely improve productivity: Better code generation, debugging, and terminal-like behavior can streamline development and maintenance work.
- Tiered models fit different budgets: Use Pro for cost-effective general workloads and upgrade to DeepThink for mission-critical high-accuracy needs.
Limitations and safety considerations
Dominant benchmark results do not mean perfection. There are real limitations to consider:
- Access tiers and gated features mean not all capabilities are immediately available to every user.
- Agentic systems require careful guardrails, monitoring, and clear error-handling to prevent unintended consequences.
- High-cost variants are expensive for continuous use; teams must analyze cost versus value.
- Benchmarks do not capture every real-world nuance. Production deployments bring messy data, adversarial inputs, and compliance requirements that must be tested separately.
How to prepare your organization
Start small and iterate. Pilot agentic workflows in clearly bounded domains such as inventory management, customer triage, or internal knowledge retrieval. Use logging, human-in-the-loop checkpoints, and rollback capability. Pair the model with identity and access controls so actions that cause downstream effects require approvals.
Leverage platforms and tooling that accelerate safe development. Integrations like Firebase, structured logging, and observability systems will make it easier to verify behavior and measure ROI.
For managed services and IT teams, this is a moment to review architecture: ensure APIs, data stores, and audit trails are ready to handle models that can act on behalf of users, make decisions, and maintain state for long periods.
Examples of near-term applications
- Autonomous micro-businesses for campus or office environments that monitor stock, replenish supplies, and handle payments.
- Interactive tutoring systems that combine video lectures, code execution, and problem solving with long-term student models.
- Customer support agents that navigate complex GUIs, pull structured data from long documents, and execute safe actions through approved APIs.
- R&D assistants that parse massive technical documents, extract relevant experiments, and draft reproducible protocols.
