Description
DeepSeek-V4.1-Flash-1017 is an open-weight multimodal AI model designed for complex reasoning, autonomous agents, software development, and visual analysis. The model is an updated version of DeepSeek-V4.1-Flash, with improvements in benchmark performance, execution speed, and output efficiency. It supports text and image processing, enabling applications that combine natural language understanding with visual interpretation and reasoning. Its one-million-token context window allows developers to analyze large documents, extensive software repositories, and lengthy interactions while maintaining contextual information. Coding capabilities include generating software, debugging existing applications, modifying codebases, and completing multistep engineering assignments. The model also supports end-to-end project generation, including interactive games, 3D scenes, and other software applications. Agentic functionality includes external tool calling, configurable reasoning effort, multi-turn conversations, and workflows involving automated research and task execution. DeepSeek provides prompt encoding libraries, inference examples, and compatibility with deployment frameworks such as Hugging Face Transformers, vLLM, and SGLang. DeepSeek-V4.1-Flash-1017 is distributed under the MIT License and can be accessed through DeepSeek's website, mobile application, and API or deployed using its publicly available model weights.
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.
