Unsupported and limited coding tools
“Not confirmed” means no reliable official setup was established, not proof that every future release is incapable. Enterprise-only support is not a personal setup guide.
Google Antigravity
Antigravity App/IDE currently has no documented native OpenAI-compatible or Anthropic custom endpoint. Its CLI does document a Gemini API key and GOOGLE_GEMINI_BASE_URL, but only for the Gemini protocol. That does not connect to the ModelFold OpenAI/Anthropic endpoints in these guides. Use Claude Code, Cline, or OpenCode instead. Unofficial patched clients and MCP model delegates are not native provider support.
Google official authentication documentation
| Tool | Scope / limitation | Official reference |
|---|---|---|
| Google Antigravity（App / IDE） | No documented OpenAI/Anthropic custom endpoint in the App/IDE sign-in flow. Unofficial settings.json overrides are not supported configuration. | Docs |
| Google Antigravity CLI | Only modelProvider=gemini with GEMINI_API_KEY and GOOGLE_GEMINI_BASE_URL is documented; this is not an OpenAI/Anthropic route. Local CLI 1.5.5 rejects both provider values before authentication; no model request was sent. | Docs |
| Gemini CLI | Official authentication uses Google/Gemini/Vertex; no native custom OpenAI or Anthropic route was established. | Docs |
| Amazon Q Developer | No official arbitrary inference endpoint configuration found. MCP integrations do not replace the model provider. | Docs |
| Kiro | Official model selection uses the product catalog; no arbitrary endpoint/key configuration found. Do not confuse Kiro with third-party Kyro. | Docs |
| Windsurf | BYOK alone does not establish an arbitrary URL override; the current official page did not establish the required field. | Docs |
| Amp | Some customer-managed connections have returned, but arbitrary compatible endpoints were not established. Old Isolated Mode guides do not apply. | Docs |
| Sourcegraph Cody | Enterprise model configuration differs from the personal extension; a current direct ModelFold setup was not established. | Docs |
| IBM Bob | Self-hosted enterprise Model Gateway supports endpoint credentials, but requires enterprise infrastructure and supported model assignments. | Docs |
| Tabnine | Enterprise admins can configure private OpenAI-compatible models; inline completion remains separate. ModelFold enterprise setup was not tested. | Docs |
| Baidu Comate / 文心快码 | The enterprise feature table lists third-party OpenAI-format models, but a personal endpoint/key setup was not established. | Docs |
| CodeGeeX | Enterprise docs mention third-party models; arbitrary personal endpoint settings were not confirmed. | Docs |
| 通义灵码 / Lingma IDE / Qoder CN IDE | Preset BYOK providers/plans do not establish arbitrary URLs; distinguish these products from the Qoder desktop app. | Docs |
| Qoder IDE | The IDE page lists preset providers. The separate desktop app with custom endpoints is included. | Docs |
| Qoder CLI | The official wizard is account/catalog-dependent; no stable arbitrary URL field was established, so no speculative settings.json is published. | Docs |
| 腾讯 CodeBuddy 独立插件 | IDE and CLI are covered. The standalone extension was not tested for the same models.json behavior. | Docs |
| MarsCode | No current official arbitrary endpoint/key setup found. TRAE CN is covered separately; historical branding is not evidence. | Docs |
| Qodo | No arbitrary endpoint setup established for the commercial product; open-source PR-Agent configuration is not proof of commercial Qodo support. | Docs |
| Augment Code | No supported custom model endpoint/key configuration established from the official CLI reference. | Docs |
| Muse Code | Official overview centers on Meta models; no current arbitrary external endpoint setup established. Community patches are not treated as native support. | Docs |
| Freebuff | Official pages describe hosted models; no custom URL/key instructions found. | Docs |
| Codebuff | The repository and BYOK references did not establish arbitrary endpoints; no confirmed base URL field found. | Docs |
| Aura（OpenRouter 榜单，游戏开发工具） | The ranked Aura is a game-development product, not the similarly named aura-code CLI. Vendor endpoint configuration was not established. | Docs |
| JetBrains Junie（IDE 内置） | The bundled IDE agent differs from Junie CLI; this directory covers custom profiles in the CLI, not arbitrary IDE agent URLs. | Docs |
