OpenCode Go is a $10-per-month subscription that supplies hosted coding models inside OpenCode. It can be a substantially cheaper way to get a managed coding-agent provider than paying for a higher-priced, single-model service, but “half-priced Claude Code replacement” is not an established benchmark. OpenCode publishes pricing, model access and allowance rules; it does not publish a like-for-like Claude Code price comparison, task-success test or productivity trial.
For developers who want several open coding models, one API key and predictable monthly billing, Go is compelling. Developers who need a particular model’s behavior, very deep capacity or their own provider keys should compare actual workloads before switching.
What OpenCode Go actually is
OpenCode Go is an optional provider subscription for the OpenCode coding-agent application, not a separate editor or standalone agent. OpenCode describes it as access to popular open coding models through two monthly plans. You subscribe in the OpenCode Console, receive an API key and select Go as a provider inside OpenCode.

You subscribe to OpenCode Go and get your API key. It’s completely optional and you don’t need to use it to use OpenCode.” You can therefore continue using OpenCode with another provider or your own API keys if Go does not fit your workload.

Current price and what the subscription covers
| Plan | Monthly price | What is established |
|---|---|---|
| OpenCode Go | $10/month | Provider subscription with access to the Go model pool and model-dependent allowances. |
| OpenCode Go Plus | $40/month | Higher-priced plan listed in the current OpenCode documentation; exact per-model limits should be checked in the live table. |
The price is a recurring monthly subscription under the current documentation. Token rates are quoted per one million tokens and differ by model, so the practical value of a plan depends on which model you select and how much context your projects consume.
How the allowance system works
Go does not provide one universal number of prompts. OpenCode expresses usage as dollar-based, model-specific allowances across three windows:
- Five-hour window: 20% of that model’s monthly limit.
- Weekly window: 50% of that model’s monthly limit.
- Monthly window: 100% of that model’s monthly limit.
Those percentages are ceilings for each model, not a promise that every model lets you spend the same number of tokens. A cheaper model can support far more requests than an expensive reasoning model before reaching its allowance.

| Model | Input price per 1M tokens | Output price per 1M tokens | Monthly model limit |
|---|---|---|---|
| GLM-5.3-Flash | $0.15 | $0.50 | $60 |
| GLM-5.3 | $1.40 | $4.40 | $15 |
| Kimi K3 | $3.00 | $15.00 | $15 |
For example, the five-hour allowance associated with a model whose monthly limit is $60 is 20% of that limit, or $12; the weekly allowance is $30. A model with a $15 monthly limit has a $3 five-hour allowance and a $7.50 weekly allowance. These are dollar-equivalent limits, not fixed prompt counts. Long files, large context windows and lengthy outputs consume the allowance faster.
Which models are available?
The roster is broad and can change as OpenCode tests and adds models. Current documentation lists entries including GLM-5.3-Flash, GLM-5.3, GLM-5.2, Kimi K3, Kimi K2.7 Code, Kimi K2.6, LongCat-2.0, LongCat 2.5 Preview Free, MiMo variants, MiniMax M3 and M2.7, Muse Spark variants, Qwen3.8 Max, Qwen3.8 Flash, DeepSeek variants and Hy3, among others.
Do not treat that list as permanent. Check the model picker at the time you subscribe, especially if your workflow depends on one model or a preview/free entry. Model names, availability and limits can change independently of the headline subscription price.
Setup: get Go running in OpenCode
- Open the OpenCode Console and subscribe to OpenCode Go or Go Plus.
- Add the requested billing details and copy the issued API key.
- Start OpenCode’s terminal user interface.
- Run
/connect. - Choose OpenCode Go as the provider and enter the API key when prompted.
- Run
/modelsand select the model for your task.
Because Go is a provider, changing models is part of normal OpenCode usage. You can choose a lower-cost model for routine edits and reserve a higher-cost model for difficult debugging, while watching the allowance shown for each model.

Is it really a Claude Code replacement?
It is reasonable to call Go a lower-cost route to hosted coding models. It is not accurate to claim proven feature or quality equivalence with Claude Code from the published evidence. OpenCode’s pages do not provide a controlled task benchmark, latency study, productivity trial or like-for-like pricing analysis against Claude Code.
The decision is best made against your own work:
- Choose Go when you want one subscription, a wide and changing model menu, an OpenCode-native workflow and a $10 entry price.
- Be cautious when your team depends on a particular model’s coding style, needs very large sustained usage or requires a provider contract and performance evidence that Go does not publish.
- Use your own keys instead when direct control over provider billing, regional availability or model versions matters more than subscription simplicity.
“Half-priced” is therefore a useful price hook only in a narrow sense: Go costs $10 per month, while a direct Claude Code comparison requires a plan, region and usage basis that are not supplied here. Lower price alone does not establish equal coding quality, capacity or reliability.
Why older price pages may look different
An older official Console page advertised $5 for the first month and then $10 per month, alongside aggregate Go limits of $12 per five hours, $30 weekly and $60 monthly. The newer documentation presents Go and Go Plus with per-model monthly limits instead. Treat the older figures as historical or version-specific rather than combining them with the current table. If a cached page conflicts with your account screen, use the limits displayed in the current Console and documentation for your subscription.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How quickly will you hit the limits?
There is no single answer because model prices and request sizes differ. Short, low-cost edits on a model such as GLM-5.3-Flash can use the allowance much more slowly than repeated long-context requests on Kimi K3 or GLM-5.3. Large repositories, pasted logs and agent loops increase both input and output tokens.
To stretch a plan, keep prompts focused, avoid sending unchanged files repeatedly, use a less expensive model for exploration and check the five-hour, weekly and monthly counters before starting a large refactor. When a window is exhausted, wait for that window to reset or switch to another configured provider; do not assume changing models bypasses every account-level restriction.
Frequently Asked Questions
Can I use OpenCode Go with Claude Code?
Go is documented as a provider inside OpenCode. The supplied documentation does not establish a supported way to install the Go subscription as a provider inside Claude Code, so treat the products as separate unless their current documentation explicitly adds that integration.
Does OpenCode Go include every model in the roster permanently?
No. OpenCode says the list can change as it tests and adds models. Verify the live /models list and the allowance for the model you intend to use.
What happens when a model reaches its allowance?
The relevant five-hour, weekly or monthly window limits further use of that model until it resets. You can wait, choose another available model or use another provider configured in OpenCode, subject to that provider’s own limits.
