Anthropic 将 Claude Opus 4.8 作为独立 API 模型提供，模型 ID 为 claude-opus-4-8。它是闭源托管模型，不同于开放权重的 Step 3.7 Flash。Opus 5 和 Opus 5.5 是后续的独立型号，不能当作 4.8 的别名。Anthropic 生命周期页面目前将 Opus 4.8 列为 active；部署前应再次核对。服务商和客户端的模型列表及账户权限可能不同，请在实际运行入口确认准确型号。
要点
The model proposes; the local client manages tools and permissions.
Tabbit Browser supplies the browser environment. Tabbit CLI exposes a task tab to a compatible local agent.
Check the exact model route and the actual browser account before the task.
Start read-only. Leave a named draft and check every cited page.
Pick the model route before opening the page
| Check | Claude Opus 4.8 | Browser task requirement |
|---|---|---|
| Model access | Confirm exact ID and provider in the client | Not provided by the browser |
| Execution | Provider-hosted inference; Anthropic hosts the model | Local agent must run the Tabbit CLI |
| Version boundary | Opus 4.8 is separate from Opus 5 and Opus 5.5 | Do not substitute versions silently |
| Login context | Not part of the model endpoint | Confirm the account in Tabbit Browser |

A safe first task: compare a dashboard record
Choose an approved, low-risk record with a stable ID. Confirm it in the Tabbit Browser yourself, then ask the local agent to inspect the visible status and updated date. The goal is a comparison note, not a site change. If the record ID differs, a field is missing, or a login prompt appears, the task should stop and report that boundary.
| Checkpoint | Keep in the draft | Stop for human review when |
|---|---|---|
| Record identity | Stable ID and page URL | ID is missing or differs |
| Each field | Visible value plus source URL | Value is inferred or stale |
| Result | Match, mismatch, or unknown | Page asks to save or submit |
| Next action | Named review note | Any change to the source system |
A prompt for a named review draft
Use this prompt with your own test record. It is a suggested workflow, not a report of a model benchmark or a completed test against a third-party account.
Task name: GEO-104 dashboard change review
Use Claude Opus 4.8 in this local agent and the installed Tabbit skill. Open the two URLs I provide in a separate Tabbit task tab. Read only record ID, status, and updated date. For every value, include its source URL. Use unknown when a field is not visible. If the ID differs, a login screen or CAPTCHA appears, or the page offers a write action, stop and report it. Do not save, submit, send, or change anything. Leave a draft named “GEO-104 — dashboard change review” with matched fields, mismatches, unknowns, and the URLs for my review.只有当本地 Agent 客户端确实能选择该模型时，才把它用于网页任务。然后再接入 Tabbit CLI。模型本身不提供浏览器、登录态或操作权限。先只读检查，最后留下一个有名称的草稿供人工复核。
配置步骤
Anthropic’s model page and lifecycle documentation describe the model and its API status. Claude Code or another client may expose model selection, but do not assume it can run Tabbit CLI until you check its local skill and launcher permissions.
For setup, see the Tabbit CLI guide, the existing-browser connection guide, the first-task checklist, and the CLI versus MCP guide. The Codex setup example and login reuse guide cover adjacent setup details. Use the browser prompt template to make stop conditions explicit. If an action is unavailable, use the click troubleshooting guide. For model-side reasoning background, see agentic reasoning in LLMs.
先在 Tabbit Browser 中确认账号和目标记录。然后在兼容的本地客户端中查找已安装的 Tabbit skill。支持命名 skill 命令的客户端可使用 /tabbit；Pi 使用 /skill:tabbit；有些客户端通过 /skills 列出 skill。Skill 是否可发现、CLI 是否能启动、客户端能否选择模型、网站是否已登录，是四项独立检查。运行安装路径中的 tabbit-cli diagnose，再启动一个有唯一名称的任务。CLI 在当前 Tabbit 环境中操作任务标签页，可复用已有登录态。单独的任务标签页让你继续浏览其他内容。这种登录态复用已用本地测试夹具验证，但不代表该模型与某个客户端的集成已验证。
留下可审阅的草稿
Anthropic’s published API ID and model lifecycle page are the source of truth for current availability. A model being active does not mean every third-party client, plan, or account can select it.
常见问题
API 模型 ID 是什么？
Anthropic 文档中的 ID 是 `claude-opus-4-8`。运行前请确认你的账户和所用服务商支持这一准确 ID。
Opus 4.8 和 Opus 5 或 5.5 相同吗？
不同。每个版本都是独立模型。请在配置和任务记录中保留准确版本，便于复现。
Opus 4.8 是开源模型吗？
不是。它是 Anthropic 托管的闭源模型，没有公开权重供本地部署。
API 会让它访问我的浏览器吗？
不会。浏览器访问由本地 Agent 和连接工具提供。Tabbit CLI 将兼容客户端接入 Tabbit 浏览器任务标签页。
怎样留下待复核的结果？
要求它保存有名称的草稿，附来源 URL，并标出未知信息。保持只读，操作前核对页面。
模型以后可能退役吗？
模型状态会变化。若工作流依赖这个 ID，部署前应查看 Anthropic 生命周期页面中的当前状态和日期。
