LM Studio mentions (29)

  • Qwen3-VL: Sharper Vision, Deeper Thought, Broader Action
    LM Studio[0] is the best "i'm new here and what is this!?" tool for dipping your toes in the water. If the model supports "vision" or "sound", that tool makes it relatively painless to take your input file + text and feed it to the model.

  • Llama-Server is All You Need (Plus a Management Layer)
    If you're running LLMs locally, you've probably used Ollama or LM Studio. They're both excellent tools, but I hit some limitations. LM Studio is primarily a desktop app that can't run truly headless, while Ollama requires SSH-ing into your server every time you want to switch models or adjust parameters. - Source: dev.to / 30 days ago
  • Running Docker MCP Toolkit with LM Studio
    LM Studio 0.3.17 introduced Model Context Protocol (MCP) support, revolutionizing how we can extend local AI models with external capabilities. This guide walks through setting up the Docker MCP Toolkit with LM Studio, enabling your local models to access 176+ tools including web search, GitHub operations, database management, and web scraping. - Source: dev.to / about 1 month ago
  • Codex CLI: Running GPT-OSS and Local Coding Models with Ollama, LM Studio, and MLX
    The real breakthrough is that Codex also supports open-source, self-hosted models. With the --oss flag or a configured profile, you can run inference locally through providers like Ollama, LM Studio, or MLX. - Source: dev.to / about 1 month ago

  • Building a Rust API with Claude Sonnet 4.5
    Sonnet has proven itself to be very powerful and capable of handling complex tasks, but lately the community were claiming that Claude is slowly getting worse and it's not as good as it first was. This is especially after OpenAI released their leading coding model Codex model for their open source Codex CLI. - Source: dev.to / 3 days ago
  • No “resume” in Codex CLI, so I built one: quickly “continue” with `codex-history-list`
    Codex CLI is an AI coding agent that runs in your terminal, but there’s still no official “resume” feature. - Source: dev.to / about 1 month ago
  • Codex CLI: Running GPT-OSS and Local Coding Models with Ollama, LM Studio, and MLX
    This file allows you to configure providers and create profiles for different models. Some options aren’t fully documented yet, but you can explore the Codex source code for details. You can also configure MCP servers here. - Source: dev.to / about 1 month ago

  • OpenAI Open Models
    Inference in Python uses harmony [1] (for request and response format) which is written in Rust with Python bindings. Another OpenAI's Rust libraries is tiktoken [2], used for all tokenization and detokenization. OpenAI Codex [3] is also written in Rust. It looks like OpenAI is increasingly adopting Rust (at least for inference).
