⚚️ Transport Architecture

Format conversion and HTTP transport extracted from run_agent.py into a pluggable agent/transports/ layer:

  • AnthropicTransport — Native Messages API
  • ChatCompletionsTransport — OpenAI-compatible
  • ResponsesApiTransport — OpenAI Responses API
  • BedrockTransport — AWS Bedrock Converse API

Each transport owns its own format conversion and API shape.

🔗 Five New Inference Paths

  • NVIDIA NIM — Optimized inference containers
  • Arcee AI — Domain-adapted models
  • Step Plan — Planning-focused inference
  • Google Gemini CLI OAuth — Native Google auth flow
  • Vercel AI Gateway — Pricing + dynamic discovery

Plus Gemini routed through native AI Studio API for better performance.

💻 Platform Expansion

QQBot — 17th Supported Platform

  • Native QQ Official API v2 adapter
  • QR scan-to-configure setup wizard
  • Streaming cursor support
  • Emoji reactions
  • DM/group policy gating (WeCom/Weixin parity)

🔧 Expanded Plugin Surface

  • Register slash commands (register_command)
  • Dispatch tools directly (dispatch_tool)
  • Veto tool execution from hooks (pre_tool_call)
  • Rewrite tool results (transform_tool_result)
  • Transform terminal output (transform_terminal_output)
  • Ship image_gen backends
  • Add custom dashboard tabs

Bundled disk-cleanup plugin included as opt-in reference.

🚀 GPT-5.5 on Day One

OpenAI's GPT-5.5 is available through ChatGPT Codex OAuth immediately, with live model discovery wired into the model picker so new OpenAI releases show up without catalog updates.

Hermes Agent shipped GPT-5.5 support within hours of OpenAI's announcement — demonstrating extremely tight integration between Nous Research projects and frontier model releases.
