RimMind-Extension-ModelService 🌐

Extended Model Gateways, OpenCode Go Subscription & Anthropic Prompt Caching for RimWorld 1.6

English | 简体中文

Enterprise multi-provider connectivity: OpenCode Go subscription, Anthropic ephemeral KV caching, and failover load balancing.

---

📖 Overview

RimMind-Extension-ModelService extends RimMind-Core with advanced cloud subscription gateways, cutting-edge caching protocols, and zero-downtime failover load balancing.

Key Highlights

• OpenCode Go Subscription Direct Access: One-click subscription preset (https://opencode.ai/zen/go/v1) with automatic session isolation headers (x-opencode-session).
• Anthropic Protocol Adapter: Implements native Anthropic messages protocol with cache_control: {"type": "ephemeral"} markings on static L0/L1 prefix layers, maximizing hardware-level KV cache reuse.
• Multi-Endpoint Latency Ping & Failover: Monitors endpoint health with millisecond ping checks and transparently shifts requests to backup providers if a primary endpoint returns HTTP 429 / 5xx errors.
