OpenCode is an open-source terminal coding agent built by the SST team that works with over 75 AI providers — Anthropic, OpenAI, Gemini, local Ollama models, and more — from a single interface. If you're tired of being locked into one AI company's tool and pricing, this episode explains why OpenCode grew to 7.5 million monthly active developers in under a year.

- OpenCode was quietly released in June 2025 by Anomaly Innovations (the SST team) and reached 160,000+ GitHub stars and 7.5 million monthly active developers within roughly a year

- The core design philosophy: the model is interchangeable; the agent loop, file editing, and context management are the product

- Supports 75+ AI providers — swap between free-tier Gemini, Groq, Claude, GPT, or fully local Ollama models with a config change, not a workflow change

- OpenCode stripped out Claude-specific OAuth code to signal vendor independence, while simultaneously partnering with OpenAI — positioning itself as infrastructure, not a workaround

- Multi-session support lets developers run parallel agent tasks from the same terminal with shared context

- A headless API mode enables CI/CD pipeline integration — automated code review and reporting without manual developer input
