General Purpose	Llama 4, DeepSeek V3	Everyday coding, chat, explanation
Code Specialized	DeepSeek Coder, CodeLlama	Code generation, debugging, refactoring
Lightweight	Mistral 7B, Qwen 2.5	Quick edits, completions, low-latency tasks
Large Context	YaRN-based models	Long-file analysis, full-project context

Run /models in opencode to see the current list.

note

Model availability changes over time — the Go lineup rotates as new open-weight models are released.

Model Quality

All models on OpenCode Go are tested against opencode's internal coding benchmark suite. The results are published transparently — each model listing includes:

• Pass rate on coding tasks.
• Latency — average time to first token.
• Context window — maximum supported context length.
• Strengths — types of tasks where the model excels.

Billing

Subscription Management

1. Visit https://opencode.ai/account/subscription.
2. View your current plan details.
3. Upgrade, downgrade, or cancel.

Pricing

OpenCode Go is priced lower than premium plans. Specific pricing is available at https://opencode.ai/pricing. The plan includes a monthly token allowance with the option to purchase additional tokens.

Why Use OpenCode Go?

Compared to Self-Hosting

Aspect	OpenCode Go	Self-Hosted Open Model
Cost	Low subscription	Hardware + electricity costs
Setup	5 minutes	Hours to days
Maintenance	None	Ongoing model updates, infrastructure
Reliability	99.9% uptime SLAs	Dependent on your hardware
Model selection	Curated, tested	Any model you can run

Compared to Premium APIs

OpenCode Go fills the gap between free limited-tier APIs and expensive premium subscriptions. It is ideal for:

• Hobbyists and independent developers.
• Teams with budget constraints.
• Prototyping and experimentation.
• Projects where open-weight models are preferred for licensing or transparency reasons.

Troubleshooting

Connection Issues

• Verify your internet connection.
• Ensure https://opencode.ai is accessible.
• Check that your API key is correctly entered.

Rate Limiting

If you encounter rate limits:

• Check your usage dashboard at https://opencode.ai/account/usage.
• Wait for the rate limit window to reset (typically 1 minute).
• Consider upgrading to a higher tier for increased limits.

Model Quality Concerns

If a model's output quality is below expectations:

• Try a different model from the Go lineup — different models excel at different tasks.
• Ensure the model's context window is appropriate for your input size.
• Report quality issues through the opencode feedback channel.

Billing Problems

• Visit the subscription management page at https://opencode.ai/account/subscription.
• Verify your payment method is up to date.
• Contact opencode support for billing disputes or questions.
