- [Eliminate Hardcoded Models, Dynamic Official Struct Discovery & Eradicate Phantom Model 429 Errors] (Fixes #3623):
- Dynamic Official Model Catalog Export & Zero Hardcoding: Added
all_model_ids()inOfficialModelCatalogand completely removed the staticvec![...]of 40+ models inget_supported_models(), delegating entirely to the authoritative official model catalog for zero-hardcoding maintenance. (Fixes #3623) - Global Data-Driven Tiered Suffix Self-Derivation: Promoted tier suffix stripping (
-high,-medium,-low,-tiered,-extra-low) to the global model pool, automatically self-deriving bare native models (such asgemini-3.8-flash,claude-sonnet-5-5, etc.) from any tiered model. (Fixes #3623) - Eradicate Phantom Model & Backward-Compatible Redirection: Completely eradicated the non-existent upstream model
claude-sonnet-4-6-thinkingfrom/v1/modelsvia baseline compliance filters, and configured seamless redirection to genuineclaude-sonnet-4-6in model specs/routing to eliminate upstream 429 errors disguised as quota exhaustion. (Fixes #3623) - Multi-Platform Configuration & Sync Alignment: Aligned CLI sync, OpenCode sync, frontend configurations, and bilingual documentation with authoritative model names. (Fixes #3623)
- Dynamic Official Model Catalog Export & Zero Hardcoding: Added
- [Claude SSE Stream Timeout Blocking Fix, 3-Stage Gradient Timeout State Machine & Tail Thought Block Remediation] (PR #3622, Fixes #3621, Thanks to @cubelikeplayDaniel):
- 3-Stage Gradient Timeout State Machine: Abstracted outbound stream lifecycle via the Template Method pattern, implementing staged initial-chunk probing, transition cliff silence, and body throughput timeouts to prevent hangs and session poisoning during long thinking. (Thanks to @cubelikeplayDaniel)
- Eradicate Heartbeat Reset Dead-Wait & Overload Retry Loops: Removed Peek heartbeat reset dead-waits and lack of global request budgets causing rotation deadlocks, resolving infinite retry loops triggered by
overloaded_errorthat caused 20+ minute freezes. (Thanks to @cubelikeplayDaniel) - Tail Thought Block Closure & Protocol Compliance: Fixed unclosed tail signed thinking blocks and redundant blocks emitted upon normal completion of thought-only requests. (Thanks to @cubelikeplayDaniel)
- Visual Settings & Multilingual Support: Added visual UI controls and environment variable overrides for streaming timeouts and keepalive intervals, complemented by full 12-language internationalization. (Thanks to @cubelikeplayDaniel)
- [彻底清除模型硬编码、全量官方结构体动态发现与幽灵模型 429 报错根治] (Fixes #3623):
- 全量官方模型结构体目录动态导出与零硬编码: 在
OfficialModelCatalog中新增all_model_ids()，将get_supported_models中 40+ 个内置模型的静态vec![...]硬编码彻底清除，完全委托给权威官方模型结构体目录，实现模型列表的零硬编码动态维护。 (Fixes #3623) - 全局数据驱动的分档后缀自派生: 将
-high/-medium/-low/-tiered/-extra-low等档位后缀的通用剥离逻辑提升至全量模型池，无论是官方结构体自带的分档模型还是账号动态下发模型，均自动自派生对应的原生无后缀裸模型（如gemini-3.8-flash、claude-sonnet-5-5等）。 (Fixes #3623) - 根治幽灵模型与平滑兼容重定向: 彻底剔除上游不存在的虚拟模型
claude-sonnet-4-6-thinking，在基准线过滤中严格拦截防止暴露；同时在协议别名路由映射中平滑重定向至真实模型claude-sonnet-4-6，彻底根除客户端误用或旧配置调用触发上游 429 并被误报为“配额耗尽”的顽疾。 (Fixes #3623) - 多端配置与同步对齐: 同步清理 CLI 同步、OpenCode 同步、前端配置及中英文文档中的过期静态幽灵模型残留。 (Fixes #3623)
- 全量官方模型结构体目录动态导出与零硬编码: 在
- [Claude SSE 流超时阻塞修复、引入三阶段梯度超时状态机与尾部思考块闭合治理] (PR #3622, Fixes #3621, Thanks to @cubelikeplayDaniel):
- 出站流生命周期三阶段梯度超时状态机: 基于模板方法模式抽象出站流生命周期，分阶段设立首包探测、过渡断崖静默期与正文吞吐梯度超时保护，杜绝长思考中断卡死与会话中毒。 (Thanks to @cubelikeplayDaniel)
- 消灭首包心跳重置与过载重试死循环: 根除首包 Peek 心跳重置超时死等与全局请求预算缺失导致的轮换假死，修复
overloaded_error诱发重试死循环导致 20+ 分钟卡死。 (Thanks to @cubelikeplayDaniel) - 尾部思考块闭合与协议合规治理: 修复尾部签名思考块未闭合与仅思考正常结束下发多余块的协议违规问题。 (Thanks to @cubelikeplayDaniel)
- 可视化配置与多语言支持: 支持流式三梯度超时与保活参数在前端可视化面板配置与环境变量覆盖，补齐 12 种多国语言国际化文案。 (Thanks to @cubelikeplayDaniel)
