Frequently Asked Questions about ERNIE 5.0
How much does the ERNIE 5.0 API cost per 1M tokens?+
ERNIE 5.0 by Baidu is priced at $1.5 per 1M input tokens and $6 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.15 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the ERNIE 5.0 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 5.0's context window?+
ERNIE 5.0 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 16,384 tokens.
Can I run ERNIE 5.0 locally on my own GPU (Open Weights)?+
No, ERNIE 5.0 is a proprietary closed-weights model hosted by Baidu. It cannot be downloaded for local GPU execution and must be accessed via Baidu's official API or cloud platform.
Does Baidu train on data sent to the ERNIE 5.0 API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Baidu Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Baidu Cloud API & Enterprise Endpoints.
How does ERNIE 5.0 perform on coding and reasoning benchmarks?+
ERNIE 5.0 achieves a composite Intelligence Index of 90/100, scoring 60% on SWE-bench Verified, 74.5% on GPQA Diamond, 86% on MMLU-Pro, and 1430 pts on Chatbot Arena Elo.
What is ERNIE 5.0 best used for?+
ERNIE 5.0 is best suited for: Ideale per il ragionamento aziendale di frontiera, la programmazione avanzata e i carichi di produzione, sistemi RAG aziendali e integrazioni API scalabili.. Assessment: Con un indice di intelligenza di 90/100, contesto da 128K e 70 tok/s, ERNIE 5.0 rappresenta una soluzione solida e ad alto valore nel catalogo Baidu.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to ERNIE 5.0:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
