Question 1

How do I run Claude Code in the cloud on AgentSky without installing it locally on my machine?

Accepted Answer

Sign up for AgentSky and start a Claude Code agent via the API or web UI. No local install is needed: AgentSky provisions a persistent cloud computer with Claude Code and your chosen Claude model. Pass your task and model in the same API call. New accounts receive $3 free credit with no card required.

Question 2

Which Claude models can I use with Claude Code on AgentSky, and why are GPT or DeepSeek models not supported?

Accepted Answer

Claude Code on AgentSky supports Claude Opus 5, Claude Fable 5, and Claude Sonnet 4.6. GPT, DeepSeek, Gemini, and Kimi models are not compatible — Anthropic's model pool only admits Claude Code clients. Claude Opus 4.8 is still executable for persisted specs but is no longer listed in the model picker for new agents.

Question 3

What does running Claude Code on AgentSky cost, and is there a way to use my existing Claude subscription to reduce costs?

Accepted Answer

New accounts receive $3 free credit with no card required. Connect a Claude Pro or Max plan via `sky auth connect` and model usage is $0 on eligible runs. Without a connected subscription, Claude Code with Claude Fable 5 ran 4,240 Arena tasks at a median cost of $4.86 per task and a 90th-percentile cost of $16.54. Current rates are on the pricing page.

Question 4

My Claude Code agent on AgentSky times out or loses context when working on a large codebase — how do I fix this?

Accepted Answer

Context overflow is the most common cause. Claude Code accumulates file content and conversation history per turn; large codebases with many open files push runs past the model's context window. Scope each task to a bounded directory or module, and use Claude Fable 5, which has the highest context capacity of the three available models. Check the task log for the exact message where truncation occurred.

Question 5

If my Claude Code agent is actively editing files and the AgentSky cloud machine restarts, will it lose the code changes it made?

Accepted Answer

The workspace and files persist across ordinary restarts. If the underlying machine is replaced, AgentSky restores the latest durable recovery point, which typically includes the working directory and recent file edits. Work in progress at the exact moment of a hard replacement may replay from the last checkpoint. Committing intermediate results with git adds a durable recovery layer on top of AgentSky's managed checkpoints.

Question 6

How do I connect my existing Claude Pro or Max subscription to AgentSky so I do not pay per-token for Claude Code model usage?

Accepted Answer

Run `sky auth connect` and complete the Anthropic OAuth flow to link your Claude account. Once connected, Claude Code uses your subscription as the model provider and eligible model usage costs $0 instead of per-token billing. The BYO connection covers Claude Code with Claude models; Codex with ChatGPT uses the same `sky auth connect` flow with an OpenAI account. Compute, tools, and connector costs remain separate from model usage.
