Is OpenCode free?
Open-source coding agent with selected temporary free models; other provider connections may cost money.
Current free offer summary
Free open-source client. The official FAQ says included free models need no account; the current list includes temporary GLM-5.3-Flash Free, DeepSeek V4.1 Flash Free and MiMo-V2.6-Flash Free offers. Exact universal quota, reset and offer end dates are unknown. One installed-client test returned HTTP 403; working inference was not confirmed.
What OpenCode does
OpenCode is an open-source coding client for terminal, desktop and editor workflows. Its official FAQ documents included free models without an account, while connected subscriptions and API providers have separate costs. Current free offers are temporary and have model-specific data rules. Our installed 1.18.21 client listed zero-price models, but one isolated GLM-5.3-Flash Free request was rejected with HTTP 403. Successful inference and a universal quota were not verified.

Best for
- ✓ Trying included free coding models
- ✓ Learning to ask bounded coding questions
- ✓ Using a coding client with your own provider
- ✓ Reviewing small proposed code changes
Important limits
- • Temporary free models may change or end without a published date
- • Universal request quota and reset are unknown
- • Our installed-client request failed with HTTP 403; inference remains unverified
- • Connected providers may require payment or subscriptions
- • Free-model data retention and training policies differ
- • Hosted terms and model rules restrict uses beyond the software license
- • A free coding route does not prove unrestricted free API access
FreeAIList verdict
A useful coding-client option to investigate for its included free models. Start with a public toy problem and confirm an actual response before relying on it. Our request failed, so this is a source-verified listing with an explicit access limitation, not a successful quality test.
Paid plans: Optional Console, Go subscriptions and connected providers are separate paid routes. Check their current pricing and billing settings; the free app does not include every model.
About this practical guide
Sources checked Oct 17, 2026
We checked OpenCode’s official site, current model documentation, configuration guide, hosted terms and repository license on October 17, 2026. In an isolated workspace, installed OpenCode 1.18.21 listed ten anonymous zero-price model entries after its metadata refreshed. One short GLM-5.3-Flash Free question failed with HTTP 403 and a message that free access must be used within OpenCode. No successful inference, code change, quality comparison or quota measurement is claimed. No login, payment, owner credentials or repository files were used; file and command tools were denied. We did not upgrade the installation. The site now points to OpenCode 2, so the tested client and current onboarding differ.
Compare Cline, OpenCode and FreebuffWhat is free, and what needs a paid provider?
OpenCode is a free open-source coding client. Its official FAQ says selected included models can be used without creating an account. Connecting a subscription or API provider is a separate route whose costs depend on that provider. Free client software does not make every connected model free.
The current model page lists temporary free offers, including GLM-5.3-Flash Free, DeepSeek V4.1 Flash Free and MiMo-V2.6-Flash Free. Availability can change. We found no fixed universal request allowance, reset schedule or end date for these offers; do not plan a deadline around unlimited access.
OpenCode’s current free-model list and pricing ↗Try a small coding question before opening a project
Use the official download and documentation for your installed version. The website now promotes OpenCode 2; our existing client was version 1.18.21. Check the version before following commands from an older tutorial, and avoid replacing an installation you still need without checking migration guidance.
Start in a disposable folder with a public, synthetic example. Open the model selector, confirm the exact model is labelled free, then ask one bounded question. Keep file edits and command execution under approval while you learn the workflow. Inspect any proposed change and run your own checks before applying it to a real project.
A small first question — our submission did not return an answer
Explain why JavaScript arrays should be copied before calling sort when the original order is needed. Give one two-line example and keep the whole response under 100 words. Do not read files, run commands or edit anything.
If a listed free model does not answer
A zero-price model entry proves advertised pricing, not a working request in every client. Our test was rejected despite running the installed OpenCode CLI. The response did not establish whether the cause was its version, request mode or another access check. We stopped there rather than changing identity headers or connecting billing to force a result.
If your request fails, record the client version, selected model and error. Check the official documentation for that version and current availability. Stop if the route asks for billing you do not want; choosing another listed tool is a reasonable fallback. Do not create extra accounts or retry repeatedly to evade limits.
OpenCode’s CLI documentation ↗Check the model’s data rules before sharing code
Free models have different data rules. The current documentation describes no-training policies for GLM-5.3-Flash Free and DeepSeek V4.1 Flash Free, while some other free offers may use submitted data for improvement. NVIDIA’s listed free endpoints are for trials and exclude personal or confidential data. Read the exact model’s current entry before sharing private work.
For a first attempt, use invented data and a small example that contains no secrets. Keep session sharing off unless you deliberately want to publish the conversation. OpenCode’s configuration guide documents sharing and permission controls; our isolated test disabled sharing and denied tools.
OpenCode configuration, sharing and permission settings ↗The app license and model terms are separate
The repository’s MIT license permits commercial use of the client software subject to its notice requirements. Hosted services and model outputs have separate terms. OpenCode’s hosted terms assign output rights subject to their conditions and include an internal-use restriction; individual model restrictions still matter. This is not blanket permission to use every free model for client work.
OpenCode also documents inference API endpoints. That does not establish an unrestricted free API for other applications: our rejected request specifically referenced use within OpenCode. This listing therefore stays in AI Coding rather than presenting the temporary offers as a verified free API allowance.
OpenCode’s hosted terms and output conditions ↗When to choose Cline instead
Consider Cline when you want another open-source coding agent connected to a provider account or local model.
A free agent client is not a free inference allowance. Check the selected provider’s costs and hardware requirements separately.

- OpenCode official site and expanded FAQ ↗
The official FAQ says included free models can be used without creating an account; external providers and subscriptions are separate. The page declares the favicon used for this listing.
- OpenCode current models, pricing and privacy ↗
Selected models are temporarily free; per-model privacy exceptions, NVIDIA trial-only restrictions, paid inference endpoints and separate billing are documented. No universal free quota or reset is established.
- OpenCode 1 setup and version guidance ↗
Official OpenCode 1 documentation covers setup and distinguishes the client from OpenCode 2, which uses the same command name.
- OpenCode CLI commands ↗
The CLI documentation covers model selection and commands. A listed model is not proof that our installed client can complete a request.
- OpenCode configuration ↗
Configuration documents layered files, inline settings, sharing controls and permissions, useful for a bounded first task.
- OpenCode hosted service terms ↗
Hosted services are separate from open-source software; terms cover internal use, output assignment, unpaid data use and third-party model conditions.
- OpenCode repository license ↗
The MIT software license permits use, modification and commercial distribution subject to retaining its notice; it is not a universal hosted-model or output license.
