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 33 curated coding models on the docs page as of 2026-10-14 (Grok 4.7/4.6, the GLM-5.3 and 5.2 lines, Kimi K3/K2.7/K2.6, Claude Haiku 5.5, the GPT 6 and 5.6 Luna pair, Qwen3.8, the DeepSeek V4 family, MiniMax M3, MiMo, LongCat, Hy3, Hy4 preview, Space Bunny, and Cat Jam Free), while the product page says “View all 32 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 2026-10-11, the Go docs were last updated 2026-10-10, and the plan has grown from a three-model Beta in March 2026 to 33 docs-listed models plus a $40 Go Plus tier. Churn is constant: GPT 6 Luna arrived 2026-09-22, Space Bunny Free appeared as a limited-time unlimited model, and Cat Jam Free joined as a third limited-time free model by 2026-10-14. 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, Hermes, Pi, jcode, ZCode, 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 genuine 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 actual request counts will not match.
- Muse Spark Contributor models train on your prompts and are region-limited.
Pricing #
Go: $10/month, cancel any time, re-verified 2026-10-14. Claude Haiku 5.5 joined the catalog at $0.10/$0.50 per 1M tokens under 100K context ($0.50/$2.50 above) with the standard $15 monthly limit, the first Anthropic model on Go, and Step 5 Preview Free joined LongCat 2.5 Preview Free as a limited-time free model (both per the docs fetched 2026-10-11, last updated 2026-10-10). By the 2026-10-14 docs fetch Cat Jam Free, a stealth model, had joined as a third limited-time free model (training on its free-period data per the privacy table), taking the docs list to 33 entries while the product page says 32. The docs also state DeepSeek’s zero-retention agreement renews monthly and currently runs through October 31, 2026. 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).

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.
