VSCodium features and specs

Open Source
VSCodium is completely open-source, removing the need to rely on proprietary software, which aligns with the values of many developers who prioritize software freedom and transparency.
No Telemetry
VSCodium has telemetry disabled by default, ensuring that users' usage data is not sent to Microsoft, which helps maintain user privacy and data security.
Full VSCode Extension Compatibility
VSCodium is fully compatible with VSCode extensions, including those on the Visual Studio Code marketplace, providing users with access to a wide range of tools and features.
Regular Updates
The project is regularly updated in sync with Microsoft’s Visual Studio Code releases, ensuring that users receive the latest features and bug fixes in a timely manner.
Cross-Platform
Like VSCode, VSCodium is available on multiple operating systems including Windows, macOS, and various Linux distributions, making it versatile for development across different environments.

Possible disadvantages of VSCodium

Lack of Official Support
VSCodium is not officially supported by Microsoft, so users have to rely on community support for troubleshooting and issues. This can be a disadvantage for those who prefer or need official customer service.
More Complex Setup for Some Features
Some features that require Microsoft services, such as certain authentication processes, can be more complex or unavailable in VSCodium compared to the standard VSCode.
Delayed Extension Updates
While VSCodium itself is updated regularly, extensions can sometimes lag behind due to additional steps required to maintain compatibility with the open-source version.
Brand Recognition
Microsoft's Visual Studio Code has stronger brand recognition, which can lead to better trust and adoption in enterprise environments compared to a relatively lesser-known project like VSCodium.
Potential Missing Features
Some proprietary features that Microsoft may add to Visual Studio Code could be absent in VSCodium, as it focuses on open-source components and may exclude any feature tied to Microsoft’s proprietary ecosystem.

OpenAI Codex CLI features and specs

Possible disadvantages of OpenAI Codex CLI

Accuracy Limitations
The generated code may not always be perfectly accurate or optimized, requiring manual review and adjustments by experienced developers.
Dependency on Internet
Since Codex CLI relies on online resources to function, its usability can be affected by internet connectivity issues.
Learning Curve
While designed for simplicity, there is still a learning curve associated with understanding the limitations and best use cases for Codex CLI.
Ethical Concerns
Relying on AI for code generation could raise concerns about the originality of code, intellectual property rights, and potential biases in the training data.
Cost
Depending on OpenAI's pricing model, using Codex CLI might involve costs that can accumulate, especially for large-scale or long-term projects.

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).
