Question 1

Can AgentSky use OpenRouter as its model backend?

Accepted Answer

AgentSky provisions the model alongside the harness through its own infrastructure — it does not currently route through OpenRouter. If you need access to a specific model that AgentSky does not yet support, OpenRouter is a natural complement: your application can call OpenRouter for that model while calling AgentSky for agent sessions that use supported harness-model pairings. The two APIs can coexist at the application layer.

Question 2

OpenRouter has 100+ models — does AgentSky support fewer?

Accepted Answer

AgentSky offers a curated set of models matched to each supported harness, covering the leading families: Claude, GPT, DeepSeek, Gemini, Kimi, and GLM. Breadth is OpenRouter's strength; AgentSky's value is that the model ships already wired into a maintained, crash-resistant agent harness. Selecting a model on AgentSky means selecting a tested pairing, not a raw completion endpoint.

Question 3

I already use OpenRouter for model routing — why would I switch to AgentSky for agents?

Accepted Answer

You probably would not switch entirely — the two solve different problems. OpenRouter gives your application model flexibility at the completion layer. AgentSky gives you the agent runtime above it: the harness, the cloud computer, persistent workspace, crash recovery, and event streaming. A common pattern is using OpenRouter for non-agent LLM calls while using AgentSky for the sessions that need a full running agent.

Question 4

Does OpenRouter support Claude Code, Codex, or Hermes as agents?

Accepted Answer

OpenRouter provides access to the models those harnesses use — Claude, GPT, DeepSeek — but not to the harnesses themselves. An OpenRouter call returns token completions; a harness like Claude Code, Codex, or Hermes is a maintained execution environment that interprets those tokens and takes file-system and tool actions inside an isolated cloud computer. AgentSky ships the harnesses; OpenRouter ships model access.

Question 5

If I have a Claude Pro or ChatGPT Plus subscription, can I use it with OpenRouter?

Accepted Answer

OpenRouter does not mediate subscriptions — it bills per token at API rates separate from your subscription. AgentSky supports BYO Claude and ChatGPT subscriptions, which can reduce model cost to $0 for those harnesses on AgentSky. BYO subscription support is an AgentSky-specific feature.

	Cloud agent platformAgentSky	Model aggregation APIOpenRouter
What you get	A running cloud agent — harness, model, persistent state, channels, and event stream — behind one API call	LLM token responses routed from any of 100+ supported models behind one OpenAI-compatible endpoint
Primary layer	Agent runtime: provisions compute, boots harness, manages workspace, streams events	Model API: routes prompts to providers, returns completions
Agent harness	8 maintained harnesses (Claude Code, Codex, Hermes, OpenClaw, pi, and more) behind one call	Not included — you build the agent loop on top of the model responses
Persistent compute	Isolated cloud computer per session; survives crashes, network drops, and closed laptops	Not included — stateless model responses; compute and state are your application's responsibility
Model breadth	Models matched to each supported harness; BYO Claude or ChatGPT subscription reduces model cost to $0	100+ models from Anthropic, OpenAI, Google, Meta, Mistral, Qwen, DeepSeek and others at near-direct pricing
Pricing model	Pay per task at list pricing; BYO subscription cuts model cost to $0; no card required to sign up	Per-token pricing at or near provider list rates; pay-as-you-go with no base fee; free models available
Best for	Running agentic coding tasks immediately without building agent infrastructure	Accessing many LLMs through one API key for chat, completions, and embedding use cases
