OpenCode pricing (2026): free, Go, Go Plus or Zen pay-as-you-go?
updated · prices checked
quick answer: OpenCode itself is free and open source (MIT). you pay for the model, one of four ways: OpenCode's free models (200 requests a day), your own API key or an existing GitHub Copilot or ChatGPT Plus or Pro login, Go at $10/mo or Go Plus at $40/mo for a curated lineup with set limits, or pay as you go on Zen from a $20 balance at the model provider's price.
OpenCode is #3 of 13 on our coding agents board (8.5/10): a Claude Code-style agent for the terminal, desktop and IDE that isn't tied to one model. which makes the pricing question really "how do you want to pay for tokens?". here's each route.
the ways to pay
| route | price | what you get |
|---|---|---|
| OpenCode app | free | the agent, MIT licensed, for terminal, desktop and IDE |
| free models | $0 | Big Pickle plus whatever's on promotion, 200 requests a day |
| your own key | your provider's rates | any of 75+ providers, local models included |
| existing login | what you already pay | log in with GitHub Copilot or ChatGPT Plus or Pro |
| Go | $10/mo | a curated set of coding models with set limits, usable from any agent |
| Go Plus | $40/mo | the same lineup with higher limits |
| Zen | pay as you go | add a $20 balance (+$1.23 card fee); per request at the provider's price |
is OpenCode free?
yes, the agent is. no seat fee, no subscription, no catch on the software. what isn't free is the model behind it, unless you use OpenCode's free models.
is it free unlimited? no. the free models come with a quota of 200 requests a day, and most of them are free "for a limited time" while their makers collect feedback. read the small print on data, too: during the free period some of them (Big Pickle among them) may use what you send to improve the model. fine for a side project, not for a client's codebase.
Go and Go Plus: the subscription
Go is $10 a month and Go Plus is $40 a month. you get a curated lineup of coding models (Kimi, GLM, Qwen, MiniMax and DeepSeek models, plus Claude Haiku 5.5 and GPT-6 Luna, among others) with limits on a rolling basis: up to 20% of your monthly allowance in any 5 hours, 50% in a week and 100% in the month. how many requests that buys depends on the model. you can top up credit if you run out, and cancel any time.
two things worth knowing:
- it works from any agent, not just OpenCode.
- some Go models are "contributor" versions (Gemini 4 Argon and Muse Spark), where your prompts may be used to train the vendor's future models. the rest don't train on your data.
Zen: pay as you go
Zen is OpenCode's pay-as-you-go model gateway (its docs now call it the Console). add a $20 balance (plus a $1.23 processing fee), auto top-up adds $20 when you hit $5, and you can set monthly spend limits. OpenCode says it charges what the model provider charges with no markup, beyond the card fee. a few of its per-million-token prices that match the vendors' own pages:
- Claude Sonnet 5.5: $2 in / $10 out
- Claude Haiku 5.5: $0.10 / $0.50 (prompts up to 100K tokens)
- GPT-6 Luna: $0.10 / $0.50 (up to 272K tokens)
Zen's providers follow a zero-retention policy and don't train on your data, with a few listed exceptions (mostly the free models).
Zen vs Go: which?
- you code most days and want a fixed bill: Go, $10
- go keeps running dry: Go Plus, $40, or Go with a top-up
- you want frontier models (Claude Sonnet or Opus, GPT-6.1 Sol) and pay for what you use: Zen, or your own key
- you already pay for GitHub Copilot or ChatGPT Plus or Pro: log in with that and pay nothing extra
- just trying it: the free models
what it costs next to the rest
| rank | tool | best for | free tier | paid from | numptr score |
|---|---|---|---|---|---|
| #3 | OpenCode | devs who want a Claude Code-style agent without being tied to one model | free and open source (MIT); free models included, or bring your own key, or log in with GitHub Copilot or ChatGPT Plus/Pro | optional OpenCode Go $10/mo or Go Plus $40/mo | 8.5/10 |
| #1 | Claude Code | delegating multi-file features from terminal or IDE | no free access: Claude Code needs a paid Claude plan (Pro and up) | Pro $20/mo | 9.0/10 |
| #5 | Cline | BYO-key developers who want control | free open-source extension (VS Code + CLI) | no subscription | 8.0/10 |
| #4 | GitHub Copilot | teams already on GitHub; budget-conscious devs | limited chat and agent usage | Pro $10/mo | 8.0/10 |
| #2 | Cursor | developers who want ai inside a full editor | limited ai usage | Plus $8/mo, Grok models only | 8.5/10 |
OpenCode's floor is a genuinely usable $0. Claude Code, the one above it, starts at $20, and Cursor's free plan is a taster. the trade-off: it isn't tuned to one model the way Claude Code is, and with your own key the bill is only as cheap as the model you pick. head-to-head: OpenCode vs Claude Code. the whole $0 to $20 ladder: cheapest ai coding agent. every plan on one page: the ai coding agent price sheet.
