Overview
CC Switch v3.15.0 is a major release following the v3.14.x line, centered on promoting Claude Desktop to a first-class managed surface. It ships third-party provider switching through the in-app proxy gateway, role-based model mapping (sonnet / opus / haiku) with a supports1m long-context flag, Copilot/Codex OAuth provider reuse, a redesigned Claude Code import flow, app-switcher differentiation between "Claude Code" and "Claude Desktop", and 44 provider presets translated from the Claude Code catalog into the new Claude Desktop surface.
Around proxy reliability, this release performs a systematic hardening pass: P0–P3 patches across routing / lifecycle / retry / failover / rectifier paths; pooled HTTPS connection reuse for non-Anthropic backends to cut per-request latency; cache hit-rate improvements for Codex and OpenAI Responses (emit prompt_cache_key only when a real client-provided session identity exists, canonicalize JSON keys in outgoing request bodies plus tool_call arguments and tool_result content, and thread session_id into the usage logger); correct Anthropic ↔ OpenAI tool_choice mapping; Vertex AI full URLs are no longer truncated; Gemini request models are now extracted from the URI path; takeover detection is tightened; and IPv6 listen addresses are supported. ChatGPT Codex OAuth providers no longer depend on hardcoded model lists — CC Switch now fetches a live model list from the ChatGPT backend on demand.
Claude Code's model mapping is now role-based (sonnet / opus / haiku) with display names and a new supports1m boolean flag, replacing the legacy [1M] suffix and decoupling routing decisions from raw model IDs. The usage dashboard adds a filter-driven Hero card that exposes cache-normalized real total tokens and cache hit rate, updated live as the active date range / provider / model filters change; paired with a fix for cache-cost semantics and the noisy pricing warning storm that fired on every request. Robustness improvements in the OpenAI Responses API usage parsing path mean missing or malformed upstream usage no longer crashes the VSCode Claude Code extension with a null output.
The provider ecosystem expands further: new BytePlus, Volcengine Agentplan, ClaudeAPI, ClaudeCN, RunAPI, RelaxyCode, PatewayAI, and Baidu Qianfan Coding Plan partner presets; DouBao Seed is promoted to partner status; and provider cards now surface a "routing support" badge so users can tell at a glance which providers can be served through Local Routing. This release also fixes a long tail of issues across Codex sessions, OAuth, Claude Desktop forms, Linux segfaults, terminal fallbacks, and ships several GitHub Actions dependency bumps.

Highlights
- Claude Desktop Becomes a First-Class Managed Surface: Third-party provider switching through the in-app proxy gateway, role-based model mapping (sonnet / opus / haiku) with a supports1m long-context flag, Copilot/Codex OAuth provider reuse, and 44 provider presets translated from the Claude Code catalog. Note: 20 Claude Desktop presets now default to direct mode instead of proxy mode — verify connectivity after upgrade if you previously relied on proxy routing.
- Major Reverse-Proxy Hardening: P0–P3 lifecycle / retry / failover / rectifier patches; pooled HTTPS reuse for non-Anthropic backends; Codex / Responses cache hit-rate improvements; correct Anthropic ↔ OpenAI tool_choice mapping; Vertex AI URL preservation; Gemini path-based model extraction; refined takeover detection; IPv6 listen address support.
- Provider Ecosystem Expansion: New BytePlus, Volcengine Agentplan, ClaudeAPI, ClaudeCN, RunAPI, RelaxyCode, PatewayAI, and Baidu Qianfan Coding Plan partner presets; DouBao Seed promoted to partner status; routing-support badges on provider cards.
- Role-Based Model Mapping with 1M Flag: Role-based sonnet / opus / haiku routing with display names and a supports1m flag replaces the legacy [1M] suffix.
- Codex OAuth Live Model Discovery: ChatGPT Codex providers fetch the live model list from the ChatGPT backend on demand.
- Usage Dashboard Filter-Driven Hero: Surfaces cache-normalized real total tokens and cache hit rate, updated live as date / provider / model filters change.
- DeepSeek Tool Calls + Zero-Usage Final Delta: DeepSeek tool calls now return reasoning_content alongside tool_calls (#2543, thanks @bling-yshs); the final message_delta always includes a usage block (even when zero) so strict Anthropic clients no longer crash on null (#2485, thanks @Myoontyee).
- OpenAI Responses API Usage Parsing Robustness: Missing or malformed upstream usage no longer crashes the VSCode Claude Code extension (#2422, thanks @magucas).
Added
Claude Desktop Third-Party Provider Switching via Proxy Gateway
CC Switch now treats Claude Desktop as a first-class managed surface alongside Claude Code / Codex / Gemini / OpenCode / OpenClaw / Hermes.
- New dedicated Claude Desktop panel that brokers third-party providers to Claude Desktop through CC Switch's in-app proxy gateway
- Routing-support badge on cards for providers that need Local Routing
- Role-based model route mapping locked to sonnet / opus / haiku
- Copilot / Codex OAuth providers can be reused in the Claude Desktop panel
- Redesigned Claude Code settings import flow
- App switcher visually distinguishes "Claude Code" from "Claude Desktop", and the app visibility settings use the "Claude Code" label
- 44 Claude Desktop provider presets translated from the Claude Code preset catalog
Routing Support Badges on Provider Cards
Provider cards in both the Claude Code and Codex panels now show a routing-support badge so users can tell at a glance which providers can be served through Local Routing.
Codex OAuth Live Model List
ChatGPT Codex providers no longer rely on a hardcoded model selection — CC Switch fetches a live model list from the ChatGPT backend on demand.
Role-Based Model Mapping with 1M Flag
Claude Code model mapping is now role-based (sonnet / opus / haiku) with display names and a supports1m boolean flag, replacing the legacy [1M] suffix and decoupling routing from raw model IDs.
Filter-Driven Usage Hero
The usage dashboard's Hero summary is now filter-driven, updating live as the active date range / provider / model filters change; it surfaces cache-normalized real total tokens and cache hit rate so the Hero figures line up with the detail list below.
Provider Form "Save Anyway" Prompt
Softened provider form input validation by turning non-blocking input issues into a "save anyway" prompt, so a harmless field issue no longer blocks saving (#2307, thanks @allenxln).
Universal Provider Duplicate Action
Added a "duplicate" button for universal providers from the provider list (#2416, thanks @hubutui).
Persisted Tauri Window State
Window position and size now persist across launches (#2377, thanks @BillSaul).
Tray Icon Tooltip
The system tray icon now surfaces a status tooltip on hover (#2417, thanks @Coconut-Fish).
Warp Terminal Session Launch
Added support for launching Warp and executing a saved session inside it (#2466, thanks @tisonkun).
DeepSeek reasoning_content for Tool Calls
DeepSeek tool-call responses now return reasoning_content and tool_calls together, so callers can render both (#2543, thanks @bling-yshs).
Baidu Qianfan Coding Plan (Claude Code)
Added a Baidu Qianfan Coding Plan preset (#2322, thanks @jimmyzhuu).
Compshare Coding Plan Preset (Cross-App)
The Compshare Coding Plan preset now lands across claude / codex / hermes / openclaw.
Partner Provider Presets
Added BytePlus, Volcengine Agentplan, ClaudeAPI, ClaudeCN, RunAPI, RelaxyCode, and PatewayAI partner presets; promoted DouBao Seed to partner status (refreshed endpoint and links).
44 Claude Desktop Provider Presets
Translated 44 provider presets from the Claude Code preset catalog into the new Claude Desktop panel.
Changed
20 Claude Desktop Presets Default to Direct Mode
20 Claude Desktop presets now ship in direct mode instead of routing through the proxy by default, reducing setup friction for users who don't need proxy-specific compatibility shims. If you previously relied on proxy routing for these presets, verify connectivity after upgrading.
