I'm @vinhnx on the internet, nice to meet you all!

Here is my personal website https://vinhnx.github.io/

This month I continue working on to refine my coding agent harness https://github.com/vinhnx/VTCode. Recently, I've added back Anthropic Claude Fable 5 and OpenAI GPT 5.6 models family (Sol, Luna, Terra). Fortunately, I've had support from the open source community and VT Code has advanced. I hope you give it a try.

I build VT Code, a Rust coding agent, from it, you can easily switch LLM providers/models and various configs like effort and plan/build/auto mode. Fable 5 included.

I have been building my own coding agent, VT Code (https://github.com/vinhnx/vtcode). I have now made it stable and mature enough, and I use it for most of my works.

Ohh nice! Maybe I'll try it, in your opinion whats the best/defining feature?

Thank you! As creator of VT Code, I think it stands out with other coding harnesses; it is the vast realm of LLM providers and models that it can support. Also, I think the main reason I started VT Code in Rust is also a main `feature`, I believe. Let me know if you have any issues using it.

I have been building coding agent: VT Code and I'm very proud of it.

https://github.com/vinhnx/VTCode > It's an open-source coding agent with LLM-native code understanding and robust shell safety. Supports multiple LLM providers with automatic failover and efficient context management.

Recently it just got the 500th tagged release. The project has been started since August 2025, and the coding agent VT Code itself I believe to be stable and ready to use. Thankfully, I got help from the community; recently, we pushed quite a lot of releases, enhancements, and bug fixes.

The former has been refreshed and rebranded. The new form URL is https://openai.com/form/codex-for-oss/

and both of them generally don't work unless you have bought many github stars

Applied in March when it first launched for VT Code, a Rust-based terminal coding agent, but haven't heard back from OpenAI. The bar seems high, which makes sense given the fund's limited scope and requirements.

I have been building tools; VT Code is my latest, and I'm very proud of it.

My coding agent VT Code has recently become a Xiaomi Orbit partner. If you want to try out Xiaomi Mimo V2.5 and V2.5 Pro in a different harness, feel free to use my VT Code. VT Code supports Mimo V2.5/Pro via official Xiaomi endpoints and via OpenRouter. Thank you!
