Baidu ERNIE
ERNIE 5 — Baidu's frontier Chinese-English bilingual LLM API
Baidu ERNIE is the LLM API from Baidu, China's largest search company. The ERNIE 5 series includes ERNIE-5.1 (balanced) and ERNIE-5.0 (frontier), both optimised for Chinese-English bilingual tasks, knowledge retrieval, and enterprise applications. Pricing is in USD via the international API.
Cloudflare Workers AI
Serverless AI inference at the edge — run LLMs in 300+ Cloudflare data centers globally
Cloudflare Workers AI runs AI inference directly on Cloudflare's global edge network across 300+ data centers, delivering ultra-low latency by processing requests close to end users. It supports a curated catalog of open-weight models including Llama 4, Mistral, Qwen3, Phi-4, and Stable Diffusion, all accessible via the Workers runtime with no cold starts. Pricing is usage-based with a generous free tier (10,000 neurons/day), making it ideal for latency-sensitive applications and edge AI use cases.

Frequently asked questions
Baidu ERNIE FAQs
What is ERNIE?
ERNIE (Enhanced Representation through Knowledge Integration) is Baidu's LLM series. ERNIE 5 is the current generation, with ERNIE-5.1 (balanced) and ERNIE-5.0 (frontier) available via the Wenxin Qianfan API.
How much does the ERNIE API cost?
ERNIE-5.1 is $0.56/$2.53 per 1M input/output tokens. ERNIE-5.0 is $1.40/$5.60 per 1M tokens. See the Baidu Cloud pricing page for current rates.
Is ERNIE good for English tasks?
ERNIE 5 handles English competently but is primarily optimised for Chinese. For English-only workloads, frontier Western models typically outperform ERNIE. For Chinese or bilingual Chinese-English tasks, ERNIE is among the strongest options available.
Cloudflare Workers AI FAQs
What is Cloudflare Workers AI?
Cloudflare Workers AI is a serverless AI inference platform that runs open-weight models on Cloudflare's global edge network across 300+ data centers. It delivers ultra-low latency by processing AI requests close to end users.
What models does Cloudflare Workers AI support?
Workers AI supports a curated catalog of open-weight models including Llama 4, Mistral 7B, Qwen3, Phi-4, and image generation models like Stable Diffusion. The catalog is smaller than Together AI but covers the most popular open-weight models.
How does Cloudflare Workers AI pricing work?
Workers AI uses a "neurons" pricing model. The free tier includes 10,000 neurons/day. Paid usage is billed per neuron, with cost varying by model size. Check developers.cloudflare.com/workers-ai/platform/pricing for current rates.

Key strengths compared
Baidu ERNIE
- Strong Chinese-English bilingual performance — best-in-class for Chinese language tasks
- Deep integration with Baidu Search knowledge graph
- ERNIE-5.1 at $0.56/$2.53 per 1M tokens is competitive for a frontier-tier bilingual model
- Primarily optimised for Chinese — English performance trails frontier Western models
- Limited ecosystem outside China; fewer third-party integrations
Cloudflare Workers AI
- Edge inference across 300+ global data centers — lowest latency for geographically distributed users
- No cold starts — inference runs on persistent GPU capacity at the edge
- Free tier: 10,000 neurons/day (roughly 10M tokens/day on small models)
- Limited model catalog vs. Together AI or OpenRouter — curated selection only
- No support for frontier proprietary models (GPT-6, Claude 5)
Key weaknesses compared
Baidu ERNIE
- Primarily optimised for Chinese — English performance trails frontier Western models
- Limited ecosystem outside China; fewer third-party integrations
- Documentation and support primarily in Chinese
Cloudflare Workers AI
- Limited model catalog vs. Together AI or OpenRouter — curated selection only
- No support for frontier proprietary models (GPT-6, Claude 5)
- Neurons-based pricing is opaque — hard to predict costs for large workloads
Provider category context
Baidu ERNIE is a frontier lab, founded in 2000. Cloudflare Workers AI is a inference api, founded in 2023. Baidu ERNIE as a frontier lab trains and serves its own proprietary models. Cloudflare Workers AI as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers but without access to proprietary frontier models.
How to choose between them
Choose Baidu ERNIE if you need Chinese NLP. Choose Cloudflare Workers AI if you need edge inference across 300+ global data centers — lowest latency for geographically distributed users. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
