Hermes Agent v0.11.0 Adds React TUI, Bedrock Support and New Transport Layer

Hermes Agent v0.11.0 Adds React TUI, Bedrock Support and New Transport Layer

Hermes Agent v0.11.0 is a substantial platform update centered on interface modernization and model connectivity. The release replaces the previous interactive CLI with a new React/Ink-based terminal UI, restructures provider communication around a pluggable transport layer, and adds native AWS Bedrock support. It also broadens inference and plugin pathways, making this version less about minor polish and more about reshaping how the agent stack is extended and operated.

What Changed

The headline change in v0.11.0 is the new Ink-based TUI, available through hermes --tui. This is a full React/Ink rewrite backed by a Python JSON-RPC service called tui_gateway. The updated interface adds a sticky composer, live streaming improvements, OSC-52 clipboard support, stable picker keys, a richer status bar with per-turn timing and git branch context, confirmation for /clear, a light theme preset, and better visibility into subagent spawning.

Under the hood, Hermes Agent also introduces a new transport abstraction. Format conversion and HTTP transport logic were pulled out of run_agent.py and reorganized into a dedicated agent/transports/ layer. In practice, that means transports such as AnthropicTransport, ChatCompletionsTransport, ResponsesApiTransport, and BedrockTransport now manage their own request and response formatting. This is a meaningful architectural change because it makes provider support more modular and easier to extend.

Native AWS Bedrock support is another major addition in this release. By integrating Bedrock through the Converse API, Hermes Agent opens a direct path to enterprise AWS-hosted model access without relying on workaround layers. The release notes also highlight five new inference paths, GPT-5.5 access through Codex OAuth, a 17th messaging platform with QQBot support, and a significantly expanded plugin surface.

Importantly, v0.11.0 also bundles in notable work that had been deferred from v0.10.0, which previously shipped only the Nous Tool Gateway. That makes this release function as a broader catch-up delivery across the stack, rather than a narrow point update.

Why It Matters

For teams building or operating agent workflows, the interface rewrite should make Hermes easier to use day to day. A better terminal UI matters because developer-facing agent systems increasingly live inside long-running interactive sessions, and usability improvements can directly affect operator speed and error rates.

The transport refactor is arguably even more important strategically. By separating model and provider communication into dedicated transport classes, Hermes Agent moves toward a cleaner multi-provider architecture. That reduces coupling, simplifies maintenance, and makes it easier to support new APIs and deployment targets over time.

Native Bedrock support strengthens Hermes Agent’s enterprise positioning, especially for organizations standardizing around AWS infrastructure, governance, and procurement. Combined with new inference paths, broader plugin extensibility, and additional messaging integrations, v0.11.0 expands Hermes from an agent runner into a more adaptable operations layer for multi-provider AI workflows.
