Pick the model that fits the job — Free-1 for quick drafts, GPT-5.4 for flagship reasoning, Kimi/Grok in between. Token-based credits, no per-token surprises, switch plans anytime with prorated upgrades.
Free-1, Free-2, Kimi K2.5/K2.6, Grok 4.1/4.20, GPT-5.1 → 5.4 — picked per task, never via vendor lock-in.
Every long-running task runs in an E2B sandbox with files, terminal, and live preview.
Drop in a SKILL.md (research, design, PPT, coding) — agent picks it up automatically when the task tags match.
Plug in any MCP server (Context7, internal tools) — managed per user with strict SSRF guards.
Heavy work is fanned out via run_agent into parallel sub-agents that share a blackboard.
Cancel mid-flight, switch sessions, come back later — the agent picks up where you left off.
