OpenCode Go vs GLM Coding Plan
Both publish their limits — one in dollars, one in credits. That single difference decides which is cheaper for you.
Updated August 28, 2026 · Independent comparison — OpenCode Go, GLM Coding Plan are separate products.
OpenCode Go
OpenCode's $10 open-model subscription
OpenCode Go is a $10/month subscription provider for OpenCode, the open-source terminal-first coding agent. Unlike most passes it publishes its caps in dollars: $12 of usage per 5 hours, $30 per week and $60 per month, alongside per-model request estimates. It covers 24 open and semi-open models and issues an API key that also works outside OpenCode. When you exhaust the cap you are not cut off — you drop to the free models, or spill into a prepaid OpenCode Zen balance if you enable 'Use balance' in the console.
GLM Coding Plan
Z.ai's GLM-5.3 subscription for coding tools
The GLM Coding Plan is Z.ai's subscription for driving coding agents with GLM-5.3 and GLM-5.3-Flash. It sells in three tiers (Lite, Pro, Max) that differ only in credit allowance, not in model access, and it is explicitly restricted to coding tools — the key is not a general-purpose API key. Credits refresh on a 5-hour rolling window and a weekly window, and off-peak usage (outside Mon-Fri 14:00-18:00 UTC+8) burns credits at half rate. Z.ai relaunched the tier pricing on 2026-07-31, so list prices differ noticeably between its CNY and USD storefronts.
Bottom line
Both publish their limits — one in dollars, one in credits. That single difference decides which is cheaper for you. Choose OpenCode Go if you want 24 models from many labs, including Grok 4.6 and GPT-5.6 Luna; choose GLM Coding Plan if gLM-5.3 is the model you actually want, at full allowance rather than a slice of a shared pool.

Stop renting one agent's model pool
Every pass on this page locks a model pool to a particular agent or gateway, and each one meters you differently. 1DevTool runs Cline, OpenCode, Claude Code, Codex CLI and Gemini CLI side by side in persistent terminals — point each at whichever pass is cheapest this month, keep your own keys, and get an HTTP client, a 13-engine database client and an embedded browser in the same window. One-time $29, no subscription.
