OpenCode Go is a subscription from the OpenCode (Anomaly) team that bundles access to a curated set of open coding models at $10/month, with a $40/month Go Plus tier above it, usable from OpenCode or any compatible coding agent.
What it is #
Go sells model access, not an editor or a harness.
You subscribe, copy an API key, and point any agent at OpenAI-compatible, Anthropic-compatible, or Responses endpoints under opencode.ai/zen/go/v1.
The lineup is 30 open-weight coding models on the docs page as of 2026-10-07 (Grok 4.7/4.6, GLM-5.3 family, Kimi K3, Qwen3.8, DeepSeek V4, MiniMax M3, MiMo, GPT 6 Luna, LongCat, Hy3, Hy4 preview, Space Bunny), while the product page still says “View all 29 models”, and only one member per workspace can hold a subscription.
Status #
Active and changing fast. The OpenCode repo shows about 208K GitHub stars on the product page footer as of 2026-10-07, the Go docs were republished 2026-10-06, and the plan has grown from a three-model Beta in March 2026 to 30 docs-listed models plus a $40 Go Plus tier. Churn is constant: GPT 6 Luna arrived 2026-09-22 and Space Bunny Free appeared as a limited-time unlimited model. Go converts $10 into up to $60 of metered usage per month, Go Plus converts $40 into up to $180, and that ratio is the entire value proposition.
Strengths #
- The $60 monthly usage value costs $10, up to 6x leverage if you max it.
- Models are benchmarked for agentic coding before inclusion, per the team.
- Works with any agent; Claude Code, Codex, Pi, jcode, and Kilo Code CLI are validated clients.
- Dollar-denominated windows make the bill predictable, free models stay available after limits, and “Use balance” falls back to your Zen balance instead of hard-stopping requests.
- Most models run with zero retention and no training on your data.
Cautions #
- This is no longer general API access.
- Since September 2026, clients must send coding-agent traffic, a real user agent, and an
x-opencode-sessionheader, which the community reads as whitelisting non-agent use. - Limits are dollar-value, so flagship tiers (Grok, Kimi K3, GLM-5.3, GPT 6 Luna) include only $15/month, with a $3 5-hour window.
- The catalog and limits change monthly, the $5 first-month promo is gone, and usage estimates assume heavy prompt caching, so your real request counts will not match.
- Muse Spark Contributor models train on your prompts and are region-limited.
Pricing #
Go: $10/month, cancel any time, as of 2026-10-06. Go Plus: $40/month, same models with 2x to 4x the per-model monthly dollar limits (Kimi K3 and GPT 6 Luna $15 to $60, GLM-5.3-Flash and Kimi K2.7 Code $60 to $180, DeepSeek V4.1 Flash $60 to $120). The DeepSeek V4-family models now bill at peak and off-peak token rates, off-peak half price, with peak at 01:00-04:00 and 06:00-10:00 UTC Monday to Friday and the dollar limits unchanged. Each model carries a monthly dollar limit on Go (mostly $60, some $30, $15 for flagships), with windows at 20% per rolling 5 hours (so $12 on a $60 model) and 50% weekly ($30). Exceeded limits fall back to free models, or to your Zen balance if you enable it. Top-ups draw on the shared Zen balance, where card fees are passed at cost (4.4% + $0.30).
Price history #
| Date | Plan | Change | Source |
|---|---|---|---|
| 2026-03-12 | Go (Beta) | Baseline: $10/month, three models (GLM-5, Kimi K2.5, MiniMax M2.5), $60 usage value | |
| 2026-08-24 | Go | First-month $5 promo removed, flat $10/month | |
| 2026-09-02 | Go | $15 monthly limit became the standard for several flagship models (community-reported) | |
| 2026-09-24 | GLM-5.3-Flash | Monthly limit doubled to $60 (docs confirm $60 by 2026-09-25) | |
| 2026-09-29 | Go Plus | New $40/month plan added above the $10 Go plan, with 2x to 4x the per-model monthly dollar limits; docs republished 2026-09-28 | |
| 2026-10-07 | Catalog | Space Bunny added as a priced model at $0.15/$0.60 per 1M tokens with a $30 monthly limit on Go, taking the docs list to 30 entries while the product page still says “View all 29 models” |
Compared to #
OpenCode Zen is the sibling pay-per-use gateway: no subscription, huge catalog including Claude and GPT, but per-token prices that can exceed OpenRouter’s. Choose Go when you want a capped, predictable bill for open models. OpenRouter has hundreds of models with routing and fallback at passthrough prices plus a 5.5% credit fee; choose it when you need frontier or long-tail models Go does not carry. Direct DeepSeek API beats Go unless you fully use the $60 cap, per a community breakdown that pegs Go at 33% cheaper only at full usage.
Bottom line #
Recommended for heavy users of open coding models who will actually burn the $60 monthly value. Not for anyone needing general-purpose API access, closed frontier models, or light usage. My disagreeable claim: at roughly 50% usage Go is about break-even with direct API pricing, so most subscribers are partly paying for slack they never consume.
Changes #
- 2026-09-26 - Created.
- 2026-09-29 - Go Plus added at $40/month with 2x to 4x the per-model monthly dollar limits, the catalog moved from 32 to 29 models (LongCat, Hy3, Hy4 preview, Qwen3.8, and GPT 5.6 Luna joined the roster), and the docs republished 2026-09-28; price history row appended.
- 2026-10-03 - Corrected the model-count claim from 30 to 29, matching the product page’s own count and the 2026-09-29 catalog bullet, with the $10/$40 tiers re-verified unchanged.
- 2026-10-06 - Converted the Compared-to cross-references from plain-text paths into working links.
- 2026-10-06 - Docs check (republished 2026-10-06): the DeepSeek V4 family gained peak and off-peak token pricing (off-peak half price, peak 01:00-04:00 and 06:00-10:00 UTC Mon-Fri), while the $10/$40 tiers, the 29-model product-page count, and the per-model dollar limits re-verified unchanged.
- 2026-10-07 - Catalog check: the docs model list moved to 30 entries with Space Bunny newly priced ($0.15/$0.60 per 1M tokens, $30 monthly limit on Go), while the product page still says “View all 29 models”; the $10/$40 tiers and the per-model dollar windows re-verified unchanged, and the repo star figure moved to about 208K on the product page footer.
