Comparación de modelos de IA muy pequeños con pesos abiertos (≤4B)

Name: Openness
Creator: Artificial Analysis
License: https://artificialanalysis.ai/docs/legal/Terms-of-Use.pdf

Modelos de IA con pesos abiertos que tienen 4B parámetros o menos. Suelen ser los modelos más pequeños en demanda de recursos.

Consideramos que un modelo tiene pesos abiertos (también denominado comúnmente «open source») cuando sus pesos están disponibles para descargar. Esto permite alojarlo en infraestructura propia y personalizarlo, por ejemplo, mediante ajuste fino.

Para más detalles sobre nuestra metodología, consulta nuestras FAQs.

K2 Horizon 3.7B y

MiniCPM5-2B son los modelos muy pequeños con pesos abiertos, definidos como aquellos con ≤4B parámetros de mayor inteligencia, seguidos por

G9v3-3B y

Granite 4.2 3B.

While model intelligence generally translates across use cases, specific evaluations may be more relevant for certain use cases.

Tamaño

Tamaño del modelo: parámetros totales y activos

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.

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.

Ventana de contexto

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).
