A command-line tool for benchmarking OpenAI-compatible inference APIs, helping developers evaluate the performance and response quality of different endpoints.
Section 01
Abacus is a command-line tool designed to benchmark OpenAI-compatible inference APIs. It helps developers evaluate and compare the performance (latency, throughput, etc.) and response quality of different API endpoints, supporting service selection, performance monitoring, and capacity planning. Key features include multi-dimensional testing, multi-endpoint comparison, and a developer-friendly CLI interface.
Section 02
With the popularity of LLM services, developers face diverse API choices (OpenAI official, Together AI, Groq, self-hosted vLLM/TGI). However, actual performance varies by factors like latency (TTFT, full response time), throughput (TPS/RPS), availability, cost, and output quality. A systematic benchmarking tool is essential for informed decisions—this is where Abacus comes in.
Section 03
Abacus supports multiple test dimensions:
Section 04
Abacus has three key technical features:
/v1/chat/completions), supports any compatible endpoint (OpenAI, Azure OpenAI, open-source托管 services) with custom base URL and API key.abacus benchmark --endpoint ...), supports config files, concurrency settings, and structured output (JSON).Section 05
Abacus applies to several scenarios:

Nornir MCP Server is an enterprise-level server based on the Model Context Protocol (MCP). It seamlessly integrates large language models (such as Claude) with the Nornir network automation framework, supporting natural language orchestration for multi-vendor network devices (Cisco, Arista, Juniper, etc.), and providing production-grade features like a dual-engine architecture (NAPALM + Netmiko), intelligent filtering, and a secure sandbox.
Bibliothèque Française LLM is a structured indexing and annotation project for French public domain literature designed specifically for large language models (LLMs). It integrates multiple authoritative sources such as DraCor, Common Corpus, and Wikisource, providing metadata indexing categorized by genre, author, and era, as well as in-depth annotations for dramatic texts (including characters, lines, stage directions, etc.). Its aim is to enable LLMs to efficiently read and understand classic French literary works.
Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
