Artificial Analysis

Comparison of Open Source Models

Comparison and analysis of open source AI models across key performance metrics including quality, performance, inference speed, context window, parameter count & licensing details.

Models are considered open source (also commonly referred to as open weights) where their weights are accessible to download. This allows self-hosting on your own infrastructure and enables customizing the model such as through fine-tuning.

For more details relating to our methodology, see our FAQs.

Kimi logoKimi K3.1 Pro and DeepSeek logoDeepSeek V4.1 Flash 1017 (max) are the highest intelligence open source models, followed by Z AI logoGLM-5.3 (max) & Xiaomi logoMiMo-V2.6-Pro.

Open Weights vs. Proprietary: Artificial Analysis Progress Index, Over Time

Artificial Analysis Progress Index v1 is an item response theory estimate of general capability across Artificial Analysis evaluations · Highest-scoring effort variant shown
Nov 2022Nov 2026

We calculate the Artificial Analysis Progress Index v1 using item response theory, which estimates model capability and task difficulty together from our benchmark results. This lets us compare models tested on different benchmarks over time.

We estimate task difficulty from which models succeed or fail, while estimating each model's capability from its results across tasks.

For example, an older model might have been tested on easier benchmarks and a newer model on harder ones. Models tested on both sets help us estimate the difference in difficulty and compare the older and newer models on the same scale.

Each line shows the highest-scoring model available at that point in time within its license category, using each model’s highest-scoring effort variant. Read the Progress Index v1 methodology.

Indicates whether the model weights are available. Models are labelled as 'Commercial Use Restricted' if commercial use is limited by conditions, and as 'Non-commercial' if the license prohibits commercial use.

  • Tiny: Less than or equal to 4B parameters. These are usually the smallest models in terms of resource demand.
  • Small: Less than 40B parameters.
  • Medium: Between 40B-150B parameters.
  • Large: Over 150B parameters.

Model Size: Total and Active Parameters

Comparison between total model parameters and parameters active during inference (billions)

The total number of trainable weights and biases in the model, expressed in billions. These parameters are learned during training and determine the model's ability to process and generate responses.

The number of parameters actually executed during each inference forward pass, expressed in billions. For Mixture of Experts (MoE) models, a routing mechanism selects a subset of experts per token, resulting in fewer active than total parameters. Dense models use all parameters, so active equals total.

Context Window

Context Window

Context window: tokens limit · Higher is better

Larger context windows are relevant to RAG (Retrieval Augmented Generation) LLM workflows which typically involve reasoning and information retrieval of large amounts of data.

Maximum number of combined input & output tokens. Output tokens commonly have a significantly lower limit (varied by model).
