Frequently Asked Questions about ERNIE Lite
How much does the ERNIE Lite API cost per 1M tokens?+
ERNIE Lite by Baidu is priced at $0 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 0% discount.
Should I use a $20/month subscription or the ERNIE Lite pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in ERNIE Lite's context window?+
ERNIE Lite features a 128K tokens context window, which equals approximately 96,000 English words or ~256 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run ERNIE Lite locally on my own GPU (Open Weights)?+
Yes, ERNIE Lite (Confidential / 3B Scale) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.
Does Baidu train on data sent to the ERNIE Lite API, and is commercial use allowed?+
100% Isolated when self-hosted on private GPUs or VPC. License tier: Open-Weights Research & Commercial License. Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.
How does ERNIE Lite perform on coding and reasoning benchmarks?+
ERNIE Lite achieves a composite Intelligence Index of 65/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 61% on MMLU-Pro, and 1180 pts on Chatbot Arena Elo.
What is ERNIE Lite best used for?+
ERNIE Lite is best suited for: alto-frequency keyword etiquetado, basic intent enrutamiento, y embedded device NLP. Assessment: un ultra-rápido, zero-costo ligero motor para mass-escala rudimentary tareas.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to ERNIE Lite:
La unidad básica de texto que procesa un modelo de lenguaje, que normalmente equivale a 3 o 4 caracteres o aproximadamente 0,75 palabras. Por ejemplo, una frase típica se divide en varios tokens.
Un conjunto estandarizado de pruebas para evaluar y comparar objetivamente las capacidades de distintos modelos de IA en tareas como programación (SWE-bench) o matemáticas avanzadas (AIME).
La cantidad máxima de tokens que un modelo puede considerar a la vez, incluyendo tanto la entrada que lee como la salida que genera. Una ventana de 1.000.000 de tokens puede procesar unas 750.000 palabras en una sola petición.
La capacidad de un modelo de detectar la necesidad de una función externa y emitir argumentos JSON estructurados para ejecutar API, búsquedas web o consultas a bases de datos.
Un protocolo abierto desarrollado por Anthropic que permite a los agentes de IA conectarse de forma estandarizada a sistemas de archivos locales, entornos de desarrollo y servicios externos.
La arquitectura de red neuronal introducida en 2017 que impulsa los LLM modernos, empleando mecanismos de autoatención para procesar secuencias completas en paralelo.
Las puntuaciones de benchmarks, precios por token y límites de tasa evolucionan rápidamente. Verifique siempre las especificaciones actuales en la documentación oficial del proveedor.
