From 9ba127c8985c289349745ebe90eb9db89b062686 Mon Sep 17 00:00:00 2001 From: yang-builds Date: Thu, 23 Apr 2026 00:05:46 +0800 Subject: [PATCH] feat: support hyphenated Claude model names (claude-sonnet-4-6, claude-opus-4-7, claude-haiku-4-5) Fix compatibility with Claude Code 2.1.x: translateModelName now converts hyphenated format (claude-sonnet-4-6) to dot notation (claude-sonnet-4.6) via regex instead of incorrectly truncating to claude-sonnet-4. Fixes: HTTP 400 errors and wrong model version display ('Sonnet 4' vs '4.6'). --- CHANGELOG.md | 21 + MAINTAINERS.md | 45 ++ README.md | 406 +++++------------- bun.lock | 1 + package.json | 20 +- src/routes/messages/non-stream-translation.ts | 11 +- 6 files changed, 184 insertions(+), 320 deletions(-) create mode 100644 CHANGELOG.md create mode 100644 MAINTAINERS.md diff --git a/CHANGELOG.md b/CHANGELOG.md new file mode 100644 index 000000000..76757806f --- /dev/null +++ b/CHANGELOG.md @@ -0,0 +1,21 @@ +# Changelog + +## v0.7.0-patch.1 (2026-04-22) + +**Fork 起点：** 基于 [ericc-ch/copilot-api v0.7.0](https://github.com/ericc-ch/copilot-api/releases/tag/v0.7.0) + +### Bug Fix + +**修复 Claude Code 2.1.x 新版模型名不兼容问题** + +- **文件：** `src/routes/messages/non-stream-translation.ts` +- **函数：** `translateModelName` +- **问题：** 原版将 `claude-sonnet-4-6` 截断为 `claude-sonnet-4`，被 GitHub Copilot 后端以 HTTP 400 拒绝；Claude Code 欢迎界面错误显示 "Sonnet 4" +- **修复：** 用正则 `^(claude-(?:sonnet|opus|haiku))-(\d+)-(\d+)$` 将连字符转换为点号，`claude-sonnet-4-6` → `claude-sonnet-4.6` +- **覆盖模型：** claude-sonnet-4-6、claude-opus-4-7、claude-haiku-4-5（及未来同格式新模型） + +--- + +## 上游版本 + +参见 [ericc-ch/copilot-api releases](https://github.com/ericc-ch/copilot-api/releases) diff --git a/MAINTAINERS.md b/MAINTAINERS.md new file mode 100644 index 000000000..18117672d --- /dev/null +++ b/MAINTAINERS.md @@ -0,0 +1,45 @@ +# 维护说明 + +## 同步上游更新 + +```bash +git fetch upstream +git log upstream/master --oneline | head -10 # 查看上游新提交 +git merge upstream/master +``` + +合并冲突大概率只在 `src/routes/messages/non-stream-translation.ts` 的 `translateModelName` 函数。 +解决冲突时，**保留本 fork 的 regex 版本**，丢弃上游的硬编码版本。 + +解决冲突后： + +```bash +bun install && bun run build +# 本地验证四条模型名 +curl -s -X POST http://localhost:4141/v1/messages \ + -H "Content-Type: application/json" \ + -d '{"model":"claude-sonnet-4-6","max_tokens":10,"messages":[{"role":"user","content":"hi"}]}' | head -c 200 +``` + +## 发版流程 + +1. 更新 `package.json` 中的 `version`（遵循 `0.7.x-patch.y` 格式） +2. 更新 `CHANGELOG.md` +3. `bun run build` +4. `git commit -am "chore: release vX.Y.Z-patch.N"` +5. `git tag vX.Y.Z-patch.N && git push && git push --tags` +6. 在 GitHub 创建 Release，附上 CHANGELOG 内容 +7. `npm publish --access public` + +## 新模型支持 + +当 Anthropic 发布新模型（如 claude-sonnet-5-0）时： +- 检查 `translateModelName` 中的正则 `^(claude-(?:sonnet|opus|haiku))-(\d+)-(\d+)$` +- 确认新命名格式是否匹配。若 Anthropic 引入全新系列名（非 sonnet/opus/haiku），在正则的 `(?:sonnet|opus|haiku)` 中添加新名称即可 + +## Patch 文件位置 + +| 文件 | 改动说明 | +|------|---------| +| `src/routes/messages/non-stream-translation.ts` | `translateModelName` 函数（核心 patch） | +| `package.json` | name / version / contributors / publishConfig | diff --git a/README.md b/README.md index 0d36c13c9..e72407659 100644 --- a/README.md +++ b/README.md @@ -1,351 +1,143 @@ -# Copilot API Proxy +# copilot-api · 解决 Claude Code 新版模型名不兼容 -> [!WARNING] -> This is a reverse-engineered proxy of GitHub Copilot API.

Use at your own risk. -```sh -bun run start -``` +--- -## Usage Tips +## License -- To avoid hitting GitHub Copilot's rate limits, you can use the following flags: - - `--manual`: Enables manual approval for each request, giving you full control over when requests are sent. - - `--rate-limit `: Enforces a minimum time interval between requests. For example, `copilot-api start --rate-limit 30` will ensure there's at least a 30-second gap between requests. - - `--wait`: Use this with `--rate-limit`. It makes the server wait for the cooldown period to end instead of rejecting the request with an error. This is useful for clients that don't automatically retry on rate limit errors. -- If you have a GitHub business or enterprise plan account with Copilot, use the `--account-type` flag (e.g., `--account-type business`). See the [official documentation](https://docs.github.com/en/enterprise-cloud@latest/copilot/managing-copilot/managing-github-copilot-in-your-organization/managing-access-to-github-copilot-in-your-organization/managing-github-copilot-access-to-your-organizations-network#configuring-copilot-subscription-based-network-routing-for-your-enterprise-or-organization) for more details. +MIT © Erick Christian (原作者) · Fork maintained by [yang-builds](https://github.com/yang-builds) diff --git a/bun.lock b/bun.lock index 20e895e7f..9ece87578 100644 --- a/bun.lock +++ b/bun.lock @@ -1,5 +1,6 @@ { "lockfileVersion": 1, + "configVersion": 0, "workspaces": { "": { "name": "copilot-api", diff --git a/package.json b/package.json index a5adbb8e7..71e730b50 100644 --- a/package.json +++ b/package.json @@ -1,19 +1,25 @@ { - "name": "copilot-api", - "version": "0.7.0", - "description": "Turn GitHub Copilot into OpenAI/Anthropic API compatible server.
