About Excession Labs
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.

UncensoredLLM
UncensoredLLM is a hosted, OpenAI-compatible API gateway for uncensored, abliterated, derestricted, and roleplay-tuned language models. Developers can select models by ID and connect from code or compatible chat, writing, and coding clients using a base URL and API key. The catalog includes builds from model families such as DeepSeek, GLM, Qwen, Gemma, Kimi, and Llama, with separate input and output token rates. The same key also provides access to image- and video-generation endpoints, billed per image or video second. Usage is deducted from a prepaid balance, and a browser playground offers a limited number of free daily turns on selected models. Public model pages show catalog details and prices, and each model receives a daily fixed-prompt check that compares reported input-token counts.

OpenCheese AI
OpenCheese AI is a hosted AI gateway and API for developers who want to connect applications and coding tools to multiple AI models through a unified service. It provides OpenAI-compatible endpoints and an Anthropic Messages-compatible interface, with model selection, API-key management, usage and balance tracking, and access to models from providers including OpenAI, Anthropic, Google, and DeepSeek. Developers can configure supported coding clients and applications to send requests through OpenCheese rather than managing separate provider credentials for each connection. The service offers both credit-based usage and time-limited plans with included balances; available models, rates, and free-model options depend on the selected model and plan. It is intended for developers evaluating or building text, coding, and image-generation workflows with hosted AI models.

OpenRouter
OpenRouter is an AI model routing platform that gives developers access to hundreds of models through a single unified API. It connects users with models from providers such as OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Qwen, xAI, and many others. The platform supports text, image, video, and audio generation while allowing developers to use one API key and a consistent interface across providers. OpenRouter can route requests based on price, performance, and availability, with fallback options that help maintain service when a provider experiences downtime. It also offers configurable data policies so organizations can control which providers receive prompts and how requests are handled. Developers can purchase credits, choose from more than 500 active models across over 80 providers, and integrate OpenRouter using an OpenAI-compatible API.
