Description

DeepSeek-V4-Flash is an optimized Mixture-of-Experts language model built for efficient large-scale AI workloads and fast inference. With 284 billion total parameters and 13 billion activated parameters, it delivers strong performance while maintaining lower computational demands compared to larger models. The model supports a massive context length of up to one million tokens, making it suitable for handling long-form content and multi-step workflows. Its hybrid attention mechanism improves efficiency by minimizing resource consumption while preserving accuracy. Trained on a dataset exceeding 32 trillion tokens, DeepSeek-V4-Flash performs well across reasoning, coding, and knowledge benchmarks. It offers flexible reasoning modes, enabling users to switch between quick responses and more detailed analytical outputs. The architecture is designed to support agentic workflows and scalable deployment environments. As an open-source model, it provides flexibility for customization and integration. Overall, DeepSeek-V4-Flash is a cost-effective and high-performance solution for modern AI applications.

Description

The Excession API grants hosted access to DeepSeek V4.1 Flash and its variant, DeepSeek V4.1 Flash Abliterated, utilizing endpoints that are compatible with OpenAI's Chat Completions, OpenAI Responses, and Anthropic Messages. Developers are empowered to incorporate these models into their applications by leveraging streaming capabilities and tool calls, and they can easily select models based on their API identifiers while monitoring usage and costs. Furthermore, the API features endpoints for model catalogs, API keys, account management, and balance inquiries, all subject to request rate limits and billing based on usage. This functionality is designed to assist developers in creating AI applications and agents, including those that require authorized security workflows with the abliterated model. Users have the flexibility to either add a pay-as-you-go balance or opt for a monthly subscription that includes API credits. Notably, both models come with a context limit of 1,048,576 tokens, and while token rates differ depending on the model, any unused credits from the monthly plan will expire upon renewal. Ultimately, the Excession API serves as a comprehensive resource for developers looking to enhance their projects with advanced AI capabilities.
