OpenCode plans and models
OpenCode is open source and free. Its built-in free models, Big Pickle first, cost nothing for a limited time. Go at $10 a month and Go Plus at $40 add 32 curated paid models with a monthly dollar allowance per model, counted over five-hour, weekly and monthly windows. OpenCode publishes those dollar figures and no request count for the free models ProPR lists.
| Plan | Price (USD) | Models | Published limits |
|---|---|---|---|
| Free | $0 | Big Pickle, Beam Free, DeepSeek V4.1 Flash Free, Flint 40B Free, GLM 5.3 Flash Free, MiMo V2.6 Flash Free, Nemotron 3.5 Lightning and Super VL Free. | Daily request limit on free models. No number published for these models. |
| OpenCode Go | $10 / month | 32 curated models: GLM-5.3-Flash, DeepSeek V4.1 Flash, Kimi K3, MiMo-V2.6-Flash, GPT-6 Luna, Claude Haiku 5.5 and more. | Monthly allowance per model: $60 GLM-5.3-Flash, $100 DeepSeek V4.1 Flash, $15 Kimi K3 and GPT-6 Luna. Extra Usage draws on credit. |
| OpenCode Go Plus | $40 / month | Same 32 models. | Higher allowances: $180 GLM-5.3-Flash, $200 DeepSeek V4.1 Flash, $60 Kimi K3 and GPT-6 Luna. |
| Console credits or your own key | Pay-as-you-go per token | Every Console model, plus any provider key you authenticate. | Metered billing with spend budgets; no plan cap. |
Every option runs headless: opencode run runs one task and exits, which is how ProPR drives it.

That plan runs in ProPR on GitHub issues and pull requests. Label an issue llm-opencode-big-pickle or llm-opencode-glm53-flash-free and ProPR plans the task, runs OpenCode in an isolated workspace, and opens the PR. You pay OpenCode or your provider directly; ProPR adds no token markup. Read how an agent subscription becomes pull requests from GitHub issues, OpenCode included.
Access
Built-in free models, an OpenCode plan, or any provider key you already have.
Role in ProPR
OpenCode runs implementation, review and follow-up passes on whichever backend you authenticate.
Free models first.
ProPR's OpenCode lineup starts with free models. Use them for low-stakes passes and zero-cost baselines in multi-model comparison runs, and add OpenCode's paid models (DeepSeek, MiMo, MiniMax, GLM, Kimi, Qwen) when you want them.
| Model | Issue label | Context | Notes |
|---|---|---|---|
| Big Pickle (default) | llm-opencode-big-pickle | 200K | OpenCode's own model and ProPR's default for everyday tasks. |
| Beam Free | llm-opencode-beam-free | 1M | Free passes over a large codebase. |
| DeepSeek V4.1 Flash Free | llm-opencode-deepseek-v41-flash-free | 200K | Fast coding passes and quick follow-ups. |
| Flint 40B Free | llm-opencode-flint-40b-free | 262K | A small open-weight model for low-stakes passes. |
| GLM 5.3 Flash Free | llm-opencode-glm53-flash-free | 200K | A free baseline for comparison runs. |
| MiMo V2.6 Flash Free | llm-opencode-mimo-v26-flash-free | 200K | Another free baseline for comparison runs. |
| Nemotron 3.5 Lightning Free | llm-opencode-nemotron35-lightning-free | 262K | Quick, low-stakes passes at zero token cost. |
| Nemotron 3.5 Super VL Free | llm-opencode-nemotron35-super-vl-free | 1M | Free passes that need a large context window. |
