## Summary

OpenCode is an open‑source, terminal‑native AI coding agent written in Go that can read, edit, and run code while understanding project structure via LSP diagnostics. The tool connects to more than 75 large language model providers, including Amazon Bedrock, allowing developers to run a coding assistant that stays inside their AWS account and incurs only pay‑per‑use charges.

The post shows how to configure OpenCode with Bedrock’s open‑weight models such as Moonshot AI’s Kimi K3, OpenAI’s GPT‑OSS 120B, and NVIDIA’s Nemotron 3 Super 120B. It highlights benefits like data residency, compliance with HIPAA, SOC 2, ISO 27001, FedRAMP and GDPR, and flexible pricing tiers (Priority, Standard, Flex) that can cut costs by up to 50 %. The article cites McKinsey’s 2025 report that 76 % of organizations plan to increase open‑source AI usage, and CrowdStrike’s claim that a fine‑tuned Nemotron achieved 96 % valid query accuracy, outperforming GPT‑4o (61 %) and Claude Sonnet 4.5 (94 %).

Ethara.AI’s production deployment is described, where OpenCode and an orchestration layer route tasks to the most suitable model, demonstrating how enterprises can build scalable, secure AI‑assisted development pipelines on Bedrock.

## Key points

- OpenCode links to 75+ LLM providers and runs on Amazon Bedrock’s managed, serverless endpoints.
- Developers can switch between Kimi K3, GPT‑OSS 120B, and Nemotron 3 Super 120B per task via a single API parameter.
- Bedrock’s Flex tier offers 50 % lower per‑token cost; data stays in‑account and complies with major security standards.

## Why it matters

Running open‑weight models on Bedrock lets developers keep code and prompts inside AWS, avoid per‑seat fees, and select the most efficient model per task, reducing costs while meeting compliance requirements.
