Step 3.7 Flash 是阶跃星辰的开放权重模型，与后续的 Step 5 Preview 是不同型号。Hugging Face 模型卡标注 Apache-2.0，官方平台也列出了 Step 3.7 Flash。托管服务入口和客户端支持情况可能变化，开始前要在服务商的模型列表中确认。Step 5 Preview 使用独立名称和模型 ID；需要复现任务时，不要互相替换。
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 | Step 3.7 Flash | Browser task requirement |
|---|---|---|
| Model access | Confirm exact ID and provider in the client | Not provided by the browser |
| Execution | Provider-hosted inference; published weights also exist | Local agent must run the Tabbit CLI |
| Version boundary | Step 3.7 Flash is separate from Step 5 Preview | Do not substitute versions silently |
| Login context | Not part of the model endpoint | Confirm the account in Tabbit Browser |
| 浏览器检查点 | 草稿记录 | 停止条件 |
|---|---|---|
| 身份 | 稳定记录 ID 和 URL | ID 缺失或不一致 |
| 证据 | 页面可见值及 URL | 需要推测 |
| 权限 | 只读对照 | 页面要求保存、发送或更新 |

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 Step 3.7 Flash 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
The official model card and provider listing are the right places to check weights, license, and current serving options. An API endpoint may support tool calls, but the browser client must still expose those tools and be able to run them locally.
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
The StepFun API platform and OpenRouter list current serving options; availability can change. The open Hugging Face weights do not imply that every local client includes a ready-made browser workflow.
常见问题
Step 3.7 Flash 是开放权重模型吗？
Hugging Face 模型卡标注 Apache-2.0。自行部署仍需要足够的硬件和兼容推理运行时。
它和 Step 5 Preview 是同一个模型吗？
不是。两者是不同发布版本，模型 ID 和服务入口也不同。调用前请在服务商处确认准确条目。
它能独自操作已登录的网页吗？
不能。模型 API 不会提供浏览器登录态。本地 Agent 和 Tabbit CLI 这样的浏览器连接工具是独立环节。
怎么确认客户端支持该模型？
打开客户端模型选择器，核对服务商和模型 ID。如果列表中没有，就改用明确支持的模型或暂停，不要默认别名等价。
可以本地运行吗？
权重已公开，但大模型需要较多算力和兼容运行时。下载前先核对模型卡与设备条件。
Agent 第一步应该做什么？
先用稳定记录 ID 执行只读任务，为每个结论附来源页面，并保存命名的审阅草稿。任何网站变更前都由你复核。
