About
BashSenpai is a terminal assistant powered by ChatGPT that transforms instructions into ready-to-use commands. By bringing ChatGPT to your terminal we give you two main benefits, the convenience of getting answers without leaving the terminal and better answers by providing context with your questions. Research has shown that self-reflection can significantly improve the quality of the answers. We implemented a multi-step process where the model can look at its own answers and improve them, before presenting them to you. Give your assistant some personality, just for fun. At its core, BashSenpai uses metadata from your system to provide more relevant and personalized command assistance. BashSenpai assumes the most commonly used settings. System metadata can be an invaluable asset, helping BashSenpai provide tailored, system-specific command suggestions that increase your productivity.

About
Leanstral 1.5 is an Apache-2.0 licensed model for practical proof engineering in Lean 4, built to make formal verification more powerful and accessible. With 119B total parameters and only 6B active parameters, it delivers a major performance upgrade for theorem proving, agentic proof engineering, and real-world code verification. Leanstral 1.5 was trained through a three-stage process: mid-training, supervised fine-tuning, and reinforcement learning with CISPO. In the multiturn environment, the model receives a theorem statement, submits a proof, gets Lean compiler feedback, and refines its approach until the proof compiles or the budget is exhausted. In the code agent environment, Leanstral works like a developer in a raw filesystem: it edits files, runs bash commands, and uses the Lean language server to inspect goals, errors, and type information in real time.
