OpenCode Go launches at $10/month — half the price of Claude Code’s entry tier, with metered access to 24 coding models, including Gemini 4 Argon and Claude Haiku 5.5. It’s not a drop-in replacement for Anthropic’s offering, but it’s already used by 300,000 active developers globally as a low-cost second subscription or primary tool for routine tasks, students, and side projects. The plan costs $5 for the first month, then $10 monthly, and includes up to $60 of model usage per month. Split into $12 every five hours and $30 per week. Premium models like Gemini 4 Argon are capped at $15 per month each. When limits hit, requests fall back to free models or draw from an optional Zen pay-as-you-go balance. Unlike Claude Code, which ties users to Anthropic’s models and interface, OpenCode Go delivers a single API key that works across compatible agents, including OpenCode’s terminal client and third-party tools. That portability, plus model-switching via /models, lets developers match cheap, fast models (e.g., Qwen3.6 Plus) to edits and reserve heavier ones (e.g., DeepSeek V4 Pro) for complex logic. The catalog mixes open-weight models. GLM-5.1, MiMo-V2.5-Pro, Kimi K2.6, and closed ones licensed through provider deals. OpenCode says its economics rely on bulk GPU reservations and negotiated per-token rates, not unlimited access. Reviewers consistently note it doesn’t match Claude Code’s raw capability on frontier tasks, but call it ‘a very good one at a price that never stings’ for everyday use. It’s not built for teams betting on a single proprietary stack. Accenture, for example, recently capped employee Claude spend at $29/month, but for individuals who want flexibility without $20–$50 monthly subscriptions. The $5 trial and free cancellation lower the barrier further. Availability is global. No regional pricing is cited. Launch date: October 17, 2026.
