Turn plain English into ready-to-run Linux commands at the prompt
Describe what you want to accomplish in ordinary English and receive a Linux command that matches the intent.
The helper works from the command line itself, so you avoid context switching to a browser or documentation site.
A simple keyword prefix lets you call the assistant only when you need it, keeping normal shell usage unchanged.
Setup instructions are distributed through the project's GitHub repository, and the site collects email addresses for release news.

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.

The AI coding agent that turns ideas into shipped software

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.

The coding agent that learns your coding taste

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.
Learn Linux, DevOps, and cybersecurity by doing — inside real online labs.

SpecialistFocuses heavily on running and fine-tuning open-source vision and language models via simple APIs, unlike OpenAI's hosted closed models.
One OpenAI-compatible API for 500+ image, video, audio, and LLM models
