Frequently asked questions
Cerebras FAQs
How fast is Cerebras inference?
Cerebras delivers significantly higher throughput than conventional GPU-based providers on GPT OSS 120B and Qwen 3.8 27B, enabling real-time agentic workflows and interactive AI applications. Check cerebras.ai for current benchmark figures.
What is the Cerebras CS-4 chip?
The CS-4 is Cerebras's latest wafer-scale chip, 58× larger than a GPU. It provides 900,000+ AI cores and massive on-chip SRAM, eliminating the memory bandwidth bottleneck that limits GPU inference speed.
What models does Cerebras support?
Cerebras supports GPT OSS 120B and Qwen 3.8 27B on the Developer tier. Enterprise adds access to all models including production and preview models. Check cerebras.ai/pricing for current rates.
Volcano Engine Doubao FAQs
What is Doubao Seed 2.1?
Doubao Seed 2.1 is ByteDance's latest LLM series, available via Volcano Engine. Pro is the frontier reasoning tier and Turbo is the balanced tier. Both support Chinese and English.
How much does the Doubao API cost?
Doubao Seed 2.1 Pro is $6.00/$30.00 per 1M input/output tokens. Doubao Seed 2.1 Turbo is $3.00/$15.00 per 1M tokens. See the Volcano Engine pricing page for current rates.
Is Doubao available outside China?
Doubao is available via Volcano Engine's international API, but the platform and documentation are primarily Chinese. Western developers may find setup more involved than with OpenAI-compatible providers.
