- Subject: Bedrock / Nova
- Open weights: yes
- Models affected: Moonshot AI Kimi K3, OpenAI GPT-OSS 120B, NVIDIA Nemotron 3 Super 120B
- Pricing: Flexible pricing: Priority for latency-sensitive production, Standard for on-demand inference (pay per token), and Flex at 50 percent lower cost for variable-latency workloads. Global cross-Region inference costs approximately 10% less than a geographic profile.

Amazon Bedrock now enables developers to run AI coding agents using open weight models privately within their AWS account. The post demonstrates how to configure OpenCode, an open source terminal-native coding agent, with open weight models on Bedrock to support multi-model workflows for coding tasks, and describes how Ethara.AI deploys this architecture in production.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/use-open-weight-models-as-your-ai-coding-agent-with-amazon-bedrock/:

> When you pair OpenCode with open weight models on Bedrock, you get a coding assistant that runs locally while inference happens securely within your AWS account. There's no infrastructure to manage and no per-seat fees.
