Frequently Asked Questions about SeedRealtime
How much does the SeedRealtime API cost per 1M tokens?+
SeedRealtime by ByteDance is priced at $0.5 per 1M input tokens and $2 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.05 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the SeedRealtime 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 SeedRealtime's context window?+
SeedRealtime 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 8,192 tokens.
Can I run SeedRealtime locally on my own GPU (Open Weights)?+
No, SeedRealtime 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 SeedRealtime 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 SeedRealtime perform on coding and reasoning benchmarks?+
SeedRealtime achieves a composite Intelligence Index of 83/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 78.5% on MMLU-Pro, and 1335 pts on Chatbot Arena Elo.
What is SeedRealtime best used for?+
SeedRealtime is best suited for: en tiempo real conversacional avatars, virtual cliente service hotlines, y interactivo smart glasses. Assessment: de ByteDance ultra-bajo latencia multimodal champion, setting un benchmark para natural voz y visión interaction.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to SeedRealtime:
La unidad básica de texto que procesa un modelo de lenguaje, que normalmente equivale a 3 o 4 caracteres o aproximadamente 0,75 palabras. Por ejemplo, una frase típica se divide en varios tokens.
Un conjunto estandarizado de pruebas para evaluar y comparar objetivamente las capacidades de distintos modelos de IA en tareas como programación (SWE-bench) o matemáticas avanzadas (AIME).
La cantidad máxima de tokens que un modelo puede considerar a la vez, incluyendo tanto la entrada que lee como la salida que genera. Una ventana de 1.000.000 de tokens puede procesar unas 750.000 palabras en una sola petición.
Un modelo de IA entrenado para invertir cómputo adicional en pensar y validar hipótesis lógicas antes de responder, diseñado para problemas complejos de ingeniería y matemáticas.
Una técnica de razonamiento paso a paso donde el modelo genera pensamientos intermedios antes de formular la respuesta final, mejorando radicalmente la resolución de problemas matemáticos y lógicos.
La capacidad de un modelo de detectar la necesidad de una función externa y emitir argumentos JSON estructurados para ejecutar API, búsquedas web o consultas a bases de datos.
Las puntuaciones de benchmarks, precios por token y límites de tasa evolucionan rápidamente. Verifique siempre las especificaciones actuales en la documentación oficial del proveedor.
