Volcengine Ark Coding Plan Guide: Tiers, Agent Plan Differences, and Setup Notes

Volcengine Ark Coding Plan is ByteDance’s AI coding model subscription for individual developers. Based on the official exported document, Coding Plan and Agent Plan now have clearly different product boundaries. Coding Plan remains coding-focused; Agent Plan is the upgraded multimodal and Harness-oriented package.

That means pricing such as “Lite ¥9.9 / Pro ¥49.9” should be checked against the plan it belongs to. In this export, the explicit ¥9.9 / ¥49.9 campaign is for Agent Plan Small / Medium, not a fixed Coding Plan Lite/Pro price.

Quick Take

Coding Plan vs Agent Plan

Do not mix credentials across plan types. The official export repeatedly notes that Agent Plan’s dedicated Base URL/API key should not be mixed with Coding Plan keys, and the same principle applies in reverse.

Check Which Plan the ¥9.9 / ¥49.9 Promo Belongs To

The official campaign page states:

So, in this official export, ¥9.9 / ¥49.9 is Agent Plan campaign pricing. If you are buying Coding Plan, verify live price, stock, and benefits on the Coding Plan page or console.

Current Model Notes

The June 2026 campaign says Agent/Coding Plan personal users get temporary deduction discounts from 2026-06-10 18:00:00 to 2026-06-30 23:59:59:

Two caveats:

• glm-5.1 is marked as retiring; switch to glm-5.2
• After the campaign, model deduction coefficients return to normal rules; always check the console

Compatible Clients

The official export covers Claude Code, OpenCode, OpenClaw, Hermes Agent, TRAE, OpenViking, and “other tools” such as Cursor, Roo Code, Kilo Code, and Codex CLI through OpenAI-compatible configuration.

For Coding Plan users, the key checks are:

• Use the dedicated Base URL from the Coding Plan console
• Use the API key for the same plan type
• Pick a model currently enabled for your plan
• Confirm whether the client uses Anthropic-compatible or OpenAI-compatible protocol

Setup: Cline + Ark

Cline uses OpenAI Compatible configuration. Older Coding Plan setups commonly look like this, but after subscribing you should copy the console-provided dedicated URL first:

API Provider: OpenAI Compatible
Base URL: https://ark.cn-beijing.volces.com/api/coding/v3
API Key: your Ark API key
Model: ark-code-latest or a specific enabled model

If you bought Agent Plan instead, use the Agent Plan OpenAI-compatible endpoint:

Base URL: https://ark.cn-beijing.volces.com/api/plan/v3
API Key: Agent Plan dedicated API key
Model: ark-code-latest or a supported model for your tier

See our Cline + Ark plan.

Setup: Claude Code + Ark

Claude Code uses the Anthropic-compatible path. Older Coding Plan setups commonly use:

export ANTHROPIC_BASE_URL="https://ark.cn-beijing.volces.com/api/coding"
export ANTHROPIC_AUTH_TOKEN="your-ark-api-key"
export ANTHROPIC_MODEL="ark-code-latest"
claude

If you bought Agent Plan, the official export gives:

export ANTHROPIC_BASE_URL="https://ark.cn-beijing.volces.com/api/plan"
export ANTHROPIC_AUTH_TOKEN="your-agent-plan-dedicated-api-key"
export ANTHROPIC_MODEL="ark-code-latest"
claude

Rule of thumb: use the Base URL and API key from the console for the plan you actually bought.

Cost Tips

1. Confirm plan type first: pure coding usually points to Coding Plan; multimodal/Harness points to Agent Plan
2. Treat ¥9.9 as campaign pricing: in this export it is Agent Plan Small’s first-two-month campaign, not long-term Coding Plan pricing
3. Start with ark-code-latest: let Ark route based on current activation, then manually switch if needed
4. Review real usage before renewing: Coding Plan uses call estimates; Agent Plan uses AFP with 5-hour, weekly, and monthly limits
5. Do not mix keys and Base URLs: mixing may fail to deduct package quota or trigger extra billing

Who It’s For

• Developers in China who mainly need coding through Cline, Claude Code, OpenCode, or Codex CLI
• People who do not need multimodal generation or Harness tools
• Users comfortable configuring OpenAI-compatible or Anthropic-compatible endpoints
• Not for anyone assuming ¥9.9 is a permanent Coding Plan price
• Not for users who need image/video/audio/search/memory/Supabase; evaluate Agent Plan instead
