Frequently Asked Questions about Hunyuan TurboS
How much does the Hunyuan TurboS API cost per 1M tokens?+
Hunyuan TurboS by Tencent is priced at $0.06 per 1M input tokens and $0.24 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.006 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Hunyuan TurboS 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 Hunyuan TurboS's context window?+
Hunyuan TurboS features a 33K tokens context window, which equals approximately 24,576 English words or ~66 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run Hunyuan TurboS locally on my own GPU (Open Weights)?+
No, Hunyuan TurboS is a proprietary closed-weights model hosted by Tencent. It cannot be downloaded for local GPU execution and must be accessed via Tencent's official API or cloud platform.
Does Tencent train on data sent to the Hunyuan TurboS API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Tencent Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Tencent Cloud API & Enterprise Endpoints.
How does Hunyuan TurboS perform on coding and reasoning benchmarks?+
Hunyuan TurboS achieves a composite Intelligence Index of 70/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 67% on MMLU-Pro, and 1225 pts on Chatbot Arena Elo.
What is Hunyuan TurboS best used for?+
Hunyuan TurboS is best suited for: Real-time customer service bots, live interactive streaming chat, and rapid intent classification. Assessment: A nimble, responsive cloud worker providing high-throughput chat at low operational cost.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Hunyuan TurboS:
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.
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.
An open standard created by Anthropic that allows AI applications and agents to connect seamlessly to local filesystems, development environments, and third-party APIs via standardized server interfaces.
A cost and latency optimization where inference providers store pre-computed attention states for repeated prompt prefixes. Reusing cached tokens typically slashes API input costs by 50% to 90% and cuts TTFT substantially.
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.
