About

Excession API provides hosted access to DeepSeek V4.1 Flash and DeepSeek V4.1 Flash Abliterated through endpoints compatible with OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages. Developers can use the models in their applications with streaming and tool calls, select models by API identifier, and review usage and costs. The API also provides model catalog, API key, account, and balance endpoints, with request rate limits and usage-based billing. It supports developers building AI applications and agents, including authorized security workflows using the abliterated model. Customers can add pay-as-you-go balance or choose a monthly plan with API credit. Both available models have a 1,048,576-token context limit; token rates vary by model, and monthly plan credit expires at renewal.
