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 and a $20-per-member Go Teams 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/inference/go/... (the docs’ current bases, since the Console rename moved paths off zen/, with the older zen/go/v1 URLs still accepted by third-party integrations).
The lineup is 32 docs-listed models as of 2026-11-08 (Grok 4.7, the GLM-5.3 and 5.2 lines, Kimi K3.1 Pro/K3/K2.7, Claude Haiku 5.5, Gemini 4 Argon at a 50% launch discount through November 30, the GPT 6 and 5.6 Luna pair, Qwen3.8 Max/Flash and Qwen3.7 Plus, the DeepSeek V4 family, MiniMax M3 and M3.1, the MiMo-V2.5 and V2.6 lines, Muse Spark Contributor pairs, LongCat-2.0, Hy3, Hy4 and Hy4 preview, and Step 5 Preview paid) against the product page’s “View all 31 models”, with Crouton Alpha Free, Beam Free, and Iceman Contributor Free the current limited-time free models and only one member per workspace holding a personal subscription.
Status #
Active and changing fast. The OpenCode repo shows about 208K GitHub stars on the product page footer as of 2026-10-11, and the plan has grown from a three-model Beta in March 2026 to 32 docs-listed models across three plans: Go $10, Go Plus $40, and Go Teams at $20 per member (added by the 2026-10-29 docs read, each member getting their own limits plus $5 more per model, and starting with Extra Usage on). Churn is constant: GPT 6 Luna arrived 2026-09-22, Kimi K3.1 Pro and Gemini 4 Argon joined by 2026-10-29, Hy4 joined as its own paid row and Crouton Alpha Free as a third stealth free model by 2026-11-08, Space Bunny Free and Cat Jam Free have left, and the docs-versus-product-page model-count mismatch that closed at 30 on 30 on 2026-10-29 reopened at 32 versus 31. 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 2026-11-08. Go Plus: $40/month, same models with 2x to 4x the per-model monthly dollar limits (Kimi K3 and K3.1 Pro and GPT 6 Luna $15 to $60, GLM-5.3-Flash and Kimi K2.7 Code $60 to $180, DeepSeek V4.1 Flash $100 to $200). Go Teams: $20 per member per month, every member carrying Go’s 5-hour and weekly windows with a monthly limit $5 higher per model (Kimi K3 $20 versus Go’s $15), and Extra Usage (overflow into the Zen balance) on by default. The catalog moved again between the 2026-10-29 and 2026-11-08 reads: Hy4 joined as its own paid row at $0.834/$2.501 per 1M tokens under a $60 monthly limit on Go ($240 Plus, $65 Teams), launched with a product-page banner, beside the retained Hy4 preview at the same rates under $30, and Crouton Alpha Free joined as a limited-time, region-limited stealth free model, taking the docs list from 30 to 32 entries while the product page reads 31. Each model carries a monthly dollar limit on Go ($15 to $100, mostly $60, $15 for flagships, DeepSeek V4.1 Flash the ceiling at $100), with windows at 20% per rolling 5 hours (so $12 on a $60 model), 50% weekly ($30), and 100% monthly. The docs also state DeepSeek’s zero-retention agreement renews monthly and currently runs through November 30, 2026. 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.

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.
