Frequently Asked Questions about Doubao Pro
How much does the Doubao Pro API cost per 1M tokens?+
Doubao Pro by ByteDance is priced at $0.8 per 1M input tokens and $3.2 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.08 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Doubao Pro 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 Doubao Pro's context window?+
Doubao Pro features a 256K tokens context window, which equals approximately 192,000 English words or ~512 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.
Can I run Doubao Pro locally on my own GPU (Open Weights)?+
No, Doubao Pro is a proprietary closed-weights model hosted by ByteDance. It cannot be downloaded for local GPU execution and must be accessed via ByteDance's official API or cloud platform.
Does ByteDance train on data sent to the Doubao Pro API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (ByteDance Terms). Full commercial ownership of generated outputs. Supported deployment channels include: ByteDance Cloud API & Enterprise Endpoints.
How does Doubao Pro perform on coding and reasoning benchmarks?+
Doubao Pro achieves a composite Intelligence Index of 88/100, scoring 58% on SWE-bench Verified, 71.5% on GPQA Diamond, 84.5% on MMLU-Pro, and 1410 pts on Chatbot Arena Elo.
What is Doubao Pro best used for?+
Doubao Pro is best suited for: 面向复杂企业级推理、软件开发与全场景生产工作流的旗舰前沿任务、企业级 RAG 检索增强生成、自动化智能体工作流与高可靠 API 集成。. Assessment: Doubao Pro 凭借 88/100 的智能得分、256K 上下文容量与 85 Token/秒的响应速度，在 ByteDance 模型矩阵中提供了极佳的性能与成本平衡。

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Doubao Pro:
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.
