FrontierAgent FrontierAgent
FrontierAgent is Apodex AI's open-source agent runtime, terminal TUI, and evaluation suite for long-horizon research and file-based work. The `frontier-agent` TUI ships a ReAct single-agent workflow and an Agent Team workflow where a coordinator maintains a task board, delegates to parallel sub-agents, collects their reports, and synthesizes the result; the same engine powers the benchmark runner used to evaluate Apodex models.
Open-sourced 2026-08-22 alongside the Apodex-1.1 model release and tech report; ~4,300 stars and ~220 forks by 2026-09-21 with active daily commits. Recent work added the Agent Team task board, Diff sidebar tab, asynchronous intervention, and a limited-time free tier on the Apodex API platform.
As of
- ReAct mode: one stateful agent that researches, reads files, writes deliverables, and runs commands
- Agent Team mode: coordinator with a live task board dispatching bounded parallel sub-agents
- Task-scoped sandbox with read-only /inputs, working /workspace, and persistent /outputs; fail-closed authorization
- TUI sidebar with Plan, Activity, Files, and Diff tabs, file previews, and approvals
- Asynchronous intervention: type mid-run to queue new steering instructions
- One-command install on macOS/Linux with no hard Docker dependency; one-shot, line mode, and session resume
- Works with any OpenAI-compatible endpoint, including self-hosted SGLang
Developers and researchers who want an open, inspectable terminal agent harness for multi-step research and file-heavy tasks, or who want to run and evaluate open-weight Apodex models with a ready-made multi-agent workflow.
Teams looking for a purpose-built coding agent with deep repo tooling (LSP, git-aware edits) or an IDE integration; FrontierAgent is oriented toward research and deliverable-generation rather than software engineering specifically.
FrontierAgent is open source under Apache-2.0 and free to run. It talks to any OpenAI-compatible endpoint: Apodex's hosted Apodex-1.1 API (metered, with a limited-time free period at launch), a self-hosted SGLang deployment of the open-weight Apodex models from Hugging Face, or other compatible providers, so costs come from the model you connect.
FrontierAgent is a well-documented, permissively licensed agent harness from a model lab, with a genuinely useful multi-agent TUI and sandboxing model. It shines for research-style, long-horizon tasks tied to Apodex models; treat it as an agent runtime to build on rather than a drop-in replacement for coding-focused CLIs like Claude Code or Codex.
