Modelos de IA con pesos abiertos
Modelos que publican sus pesos entrenados bajo licencia — self-hosting, fine-tuning y entornos regulados.
¿Qué es esto?
- Los modelos de pesos abiertos publican sus pesos (a menudo bajo Apache 2.0, MIT o una licencia de investigación abierta).
- Nota: pesos abiertos ≠ código abierto — los datos de entrenamiento y el código no suelen publicarse.
Por qué importa
- Self-hosting en tus propias GPUs, fine-tuning con datos privados, operación offline, despliegue en entornos regulados.
- La tabla muestra el host API más barato — con hardware propio el mismo modelo puede funcionar sin coste de API.

Frequently asked questions
How many AI models support pesos abiertos?
931 canonical models in our database currently support pesos abiertos. The list is regenerated on every data refresh, so it always reflects the latest releases tracked in our catalogue.
What is the cheapest model with pesos abiertos?
Qwen3.8 27B from Alibaba (Qwen) is currently the lowest-priced option, at $0.001 per 1M input tokens and $0.001 per 1M output tokens. The full table above is sorted price-ascending.
Which model with pesos abiertos has the largest context window?
Llama 4 Scout 17B Instruct (US) (Meta) leads on context at 10M tokens. This may matter if you also need long-document understanding alongside pesos abiertos.
Which models are available on the most providers?
Production-readiness usually correlates with how many independent providers host the same weights. The top three by provider count are: GLM-5.3-Flash (92), GLM-5.3 (92), GLM-5.2 (90).
How is pesos abiertos different from a regular LLM?
Open-weight models publish their trained weights publicly. You can self-host on your own GPUs, fine-tune on private data or run offline. Note: open weights ≠ open source — training data and code are usually not released.
How often is this list updated?
Daily. Our data pipeline syncs once a day, regenerates the canonical model list, and rebuilds these pages so newly released models appear within 24 hours.
