Adaptive and budgeted thinking

Adaptive controls and adjustable thinking budgets allow you to balance performance and cost.

Calibrated
The model explores diverse thinking strategies, leading to more accurate and relevant outputs.
Controllable
Developers have fine-grained control over the model's thinking process, allowing them to manage resource usage.
Adaptive
When no thinking budget is set, the model assesses the complexity of a task and calibrates the amount of thinking accordingly.

Gemini 2.5 Deep Think

An enhanced reasoning mode that uses cutting edge research techniques in parallel thinking and reinforcement learning to significantly improve Gemini’s ability to solve complex problems.

Deep Think can better help tackle problems that require creativity, strategic planning, and making improvements step-by-step.

Iterative development and design
We’ve seen impressive results on tasks that require building something by making small changes over time.
Aiding scientific and mathematical discovery
By reasoning through complex problems, Deep Think can act as a powerful tool for researchers.
Algorithmic development and code
Deep Think excels at tough coding problems where problem formulation and careful consideration of tradeoffs and time complexity is paramount.

Methodology

Gemini results: All Gemini scores are pass @1."Single attempt" settings allow no majority voting or parallel test-time compute; "multiple attempts" settings allow test-time selection of the candidate answer. They are all run with the AI Studio API with default sampling settings. To reduce variance, we average over multiple trials for smaller benchmarks. Aider Polyglot score is the pass rate average of 3 trials. Vibe-Eval results are reported using Gemini as a judge. Google's scaffolding for "multiple attempts" for SWE-Bench includes drawing multiple trajectories and re-scoring them using model's own judgement. For Aider results differ from the official leaderboard due to a difference in the settings used for evaluation (non-default).

Result sources: Where provider numbers are not available we report numbers from leaderboards reporting results on these benchmarks: Humanity's Last Exam results are sourced from https://agi.safe.ai/ and https://scale.com/leaderboard/humanitys_last_exam, LiveCodeBench results are from https://livecodebench.github.io/leaderboard.html (1/1/2025 - 5/1/2025 in the UI), Aider Polyglot numbers come from https://aider.chat/docs/leaderboards/. FACTS come from https://www.kaggle.com/benchmarks/google/facts-grounding. For MRCR v2 which is not publically available yet we include 128k results as a cumulative score to ensure they can be comparable with other models and a pointwise value for 1M context window to show the capability of the model at full length. The methodology has changed in this table vs previously published results for MRCR v2 as we have decided to focus on a harder, 8-needle version of the benchmark going forward.
