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.

Description

Spanlens is an open-source observability platform licensed under MIT that enables developers to effectively track each interaction their applications have with services like OpenAI, Anthropic, Gemini, Mistral, OpenRouter, Azure OpenAI, or a local Ollama model. The integration process is incredibly simple, requiring just a single line of code to change the client's baseURL to the Spanlens proxy, or by executing "npx @spanlens/cli init," which prompts a wizard to automatically adjust your code. Once integrated, all requests are meticulously logged, capturing details such as the model used, token counts, latency, cost, and the complete prompt and response body, while also seamlessly reconstructing streaming responses. The accompanying dashboard transforms this raw log data into actionable operational insights. Cost tracking functionality allows users to break down expenditures by individual requests, models, and end users, while also distinguishing prompt-cache tokens to provide clarity on actual savings rather than simply the total costs. Additionally, agent tracing presents multi-step workflows visually, using Gantt waterfalls and node-and-edge graphs to emphasize the critical path, enabling developers to pinpoint the slowest dependencies in a fan-out scenario. This comprehensive approach not only enhances visibility but also empowers users to optimize their model interactions for better efficiency and cost management.
