MATHCODE

MathCode is a frontier mathematical coding agent. It has a built-in math formalization engine that converts problems from plain language into Lean 4 theorems and attempts formal proofs. It features a persistent Lean REPL, reusable theorem and axiom libraries, agent proving, and an Obsidian knowledge graph. The math formalization and proving pipeline is based on the AUTOLEAN project.

NEEDLE

Cactus Compute has released Needle 2, an open 45-million-parameter model for tool calling, device use, and structured data extraction. The entire model is a single 14MB binary that runs a full session in about 28MB of RAM. On benchmarks, it trades wins with models 5x to 70x larger, including FunctionGemma 270M, LFM2.5 230M, and Apple FM, while running at 2-bit quantization against their 16-bit versions. It installs via pip and supports LoRA fine-tuning, with weights available on Hugging Face.

UNSLOTH

Unsloth is a local tool for running, training, and deploying AI models that supports a wide range of models including Qwen3, DeepSeek, Gemma 4, and image generation models like FLUX. It comes in three forms: a desktop app, a web UI called Unsloth Studio, and a code-based version called Unsloth Core. A feature called Unsloth Start connects external coding agents like Claude Code and Codex to local models with a single command.
