American Invitational Mathematics Examination (AIME) 2025 problems.

AIME-2025

Nemotron 3 Nano is a 31.6B parameter hybrid large language model developed by NVIDIA, released on December 15, 2025. It employs a novel Hybrid Mamba-Transformer Mixture-of-Experts (MoE) architecture, activating only ~3.2B parameters per token for efficient inference. Optimized for agentic AI, reasoning, and coding, it supports a 1 million token context window and features a 'Reasoning ON/OFF' toggle with a configurable thinking budget. NVIDIA has released the model with open weights, training data, and training recipes under the NVIDIA Open Model License.

Nemotron 3 Nano

GPT-OSS-20B is a medium-sized open-weight language model that delivers similar results to OpenAI o3‑mini on common benchmarks and can run on edge devices with just 16 GB of memory. This makes it ideal for on-device use cases, local inference, or rapid iteration without costly infrastructure. Despite its smaller size, it demonstrates strong performance on reasoning tasks, tool use, and competition mathematics.

GPT-OSS-20B

GPT-OSS-120B is a state-of-the-art open-weight language model that delivers strong real-world performance at low cost. This 120 billion parameter mixture-of-experts model achieves near-parity with OpenAI o4-mini on core reasoning benchmarks while running efficiently on a single 80 GB GPU. It was trained using reinforcement learning and techniques informed by OpenAI's most advanced internal models, including o3 and other frontier systems.

GPT-OSS-120B

Advanced coding-focused language model with significant improvements in multilingual agentic coding, terminal-based tasks, UI generation, tool using, and complex reasoning. Features Interleaved Thinking, Preserved Thinking, and Turn-level Thinking capabilities for enhanced stability in complex multi-turn tasks. Achieves substantial gains over GLM-4.6 across coding benchmarks, web browsing, and mathematical reasoning.

GLM-4.7

xAI's most advanced model yet, blending superior reasoning with extensive pretraining knowledge. Trained on the Colossus supercluster with 10x the compute of previous state-of-the-art models. Features test-time compute and reasoning capabilities through reinforcement learning, allowing it to think for seconds to minutes while correcting errors and exploring alternatives. Achieved an Elo score of 1402 in the Chatbot Arena.

Grok 3

A smaller model optimized for fast, cost-efficient reasoning. Achieves remarkable performance for its size and cost, particularly in math, coding, and visual tasks. It is the best-performing benchmarked model on AIME 2024 and 2025, with significantly higher usage limits than o3.

o4-mini

xAI's latest generation model with enhanced mathematical reasoning capabilities, showing significant improvements in competition-level mathematics benchmarks. Features 2x faster end-to-end latency, supports 5 different voices, and achieves 10x daily user seconds compared to previous models.

Grok 4

A smaller, more efficient version of Grok 3 from xAI. Represents a new frontier in cost-efficient reasoning, particularly strong on STEM tasks that don't require as much world knowledge. Also features test-time compute and reasoning capabilities through the Grok 3 mini (Think) variant, achieving impressive performance on mathematical and coding benchmarks while being more resource-efficient than the full Grok 3 model.

Grok 3 Mini

Gemini 2.5 Pro is capable of reasoning through its thoughts before responding, resulting in enhanced performance and improved accuracy. Features Deep Think, an enhanced reasoning mode, and native audio outputs that capture subtle nuances of speech.

Gemini 2.5 Pro

Improved across key benchmarks for reasoning, multimodality, code and long context while getting even more efficient. Best for fast performance on complex tasks.
