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

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

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

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

The o1 model series is trained with large-scale reinforcement learning to reason using chain-of-thought. OpenAI o1 is the next model in this series (previously OpenAI o1-preview), with advanced reasoning capabilities that provide new avenues for improving safety and robustness. The model can reason about safety policies in context when responding to potentially unsafe prompts, through deliberative alignment.

Anthropic's most intelligent model to date and the first hybrid reasoning model on the market. Claude 3.7 Sonnet can produce near-instant responses or extended, step-by-step thinking that is made visible to the user. API users have fine-grained control over how long the model can think for (up to 128K tokens). Priced at $3 per million input tokens and $15 per million output tokens at launch, including thinking tokens.

Claude 3.7 Sonnet

DeepSeek-R1 is a first-generation reasoning model trained via large-scale reinforcement learning. Built on DeepSeek-V3-Base, it incorporates cold-start data before RL to address challenges like endless repetition and poor readability found in DeepSeek-R1-Zero. Achieves performance comparable to OpenAI-o1 across math, code, and reasoning tasks through advanced chain-of-thought reasoning capabilities.

DeepSeek-R1

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

Flagship GPT model for complex tasks. It is well suited for problem solving across domains. Features major improvements in coding, instruction following, and long context comprehension.

GPT-4.1

A powerful Mixture-of-Experts (MoE) language model with 671B total parameters and 37B activated for each token. Features Multi-head Latent Attention (MLA) and DeepSeekMoE architectures with innovative auxiliary-loss-free load balancing and multi-token prediction training. Pre-trained on 14.8T high-quality tokens with only 2.788M H800 GPU hours.
