+# GPT-6.1 Terra
+
+## Overview
+
+GPT-6.1 Terra is an OpenAI GPT-6 series model [released on October 26, 2026](https://developers.openai.com/api/docs/changelog), focused on efficient visual reasoning, precise computer use, and clear, natural writing. It combines text and image understanding with configurable reasoning for everyday professional workflows. On B.AI, use the model ID `gpt-6.1-terra`.
+
+## Key Features
+
+- **Visual Reasoning**: Interprets product photos, technical drawings, and application screenshots to support comparison and analysis.
+- **Computer Use**: Works with computer-use tools to navigate interfaces and carry out tasks across applications.
+- **Natural Writing**: Drafts and revises concise text from supplied material, with attention to audience and voice.
+- **Adjustable Reasoning**: Six effort settings, including `none`, let applications balance reasoning depth, response time, and token consumption.
+- **Long Working Context**: A 1.05M-token context window accommodates substantial reference material and conversation history.
+
+## Best Use Cases
+
+- **Visual Review and Matching**: Matching product images to catalog entries or comparing technical drawings against requirements.
+- **Application Workflows**: Completing screen-based tasks with a defined outcome, such as entering information or updating records through connected tools.
+- **Business Writing**: Turning supplied notes and reference material into concise drafts, summaries, and revisions.
+- **Scoped Code Fixes**: Making targeted changes to existing code when requirements and verification steps are clear.
+
+## Capabilities and Limitations
+
+| Capability | Description |
+| :--- | :--- |
+| **Reasoning** | Supports `none`, `low`, `medium` (default), `high`, `xhigh`, and `max`. |
+| **Multimodal** | Text and image input; text output. Native audio and video input or output are unsupported. |
+| **Context Window** | [1,050,000 tokens](https://developers.openai.com/api/docs/models/gpt-6.1-terra), shared by input and generated tokens. |
+| **Max Output** | 128,000 tokens, including reasoning and visible output. |
+| **Tool Use** | Supports function calling, web and file search, computer use, code execution, MCP, and image generation through tools in the Responses API. |
+| **Structured Output** | Supports Structured Outputs and streaming. |
+| **Prompt Caching** | Supports implicit and explicit caching through the Responses API, with a 30-minute or 12-hour minimum lifetime. |
+| **Knowledge Cutoff** | June 1, 2026. |
+
+### Known Limitations
+
+- Tool calling requires the Responses API; Chat Completions supports requests without tools.
+- With reasoning enabled, `temperature`, `top_p`, and log-probability controls are unsupported. Fine-tuning is unavailable.
+- Reasoning can increase latency and consume the output budget before a complete visible answer is produced.
+- For complex projects and demanding analysis, GPT-6.1 Sol or GPT-6 Astra may be a better fit.

+
+- Above 272K input tokens, the higher rates apply to the entire request, not only the portion above the threshold.
+- Cache-write rates replace the ordinary input charge for those tokens. The default minimum cache lifetime is 30 minutes; 12-hour caching has a higher write rate but the same cache-read rate. The 30-minute write rate is 1.25x the applicable input rate, the 12-hour write rate is 2.5x, and cache reads are 0.05x.
+- Web search costs `10,000 Credits` (`$0.01`) per use and is not affected by the context tier.

**Cache pricing:** `Cache Write` indicates the price charged when cache writing occurs; it does not mean that all models use the same cache retention period. Cache policies, retention periods, long-context pricing, and extended caching capabilities may vary by model. If a model uses special caching rules, 1-hour cache write pricing, or time-based pricing, refer to its model detail page.
+**GPT cache-write lifetimes:** GPT-5.6 Sol, Terra, and Luna; GPT-6 Astra, Sol, and Luna; and GPT-6.1 Sol and Terra distinguish 30-minute and 12-hour cache writes, priced at 1.25x and 2.5x the applicable input rate, respectively. These write rates replace the ordinary input charge for those tokens, rather than adding to it. Cache-read rates are the same for both lifetimes.
+
+**Long-context pricing:** Some models use tiered long-context pricing. The table shows their base-tier rates; see the corresponding model detail pages for thresholds, full prices, and billing rules.
+
**Kimi K3.1 Pro / Highspeed:** The table shows the default 5-minute cache write rates. See the [model detail page](./models/kimi-k3.1-pro.md) for 1-hour cache write prices and cache renewal rules.
**Claude Haiku 5.5:** The table shows 5-minute cache write rates. Prompts over 100,000 tokens use the higher token rates for the entire request, including output and cached tokens. See the [model detail page](./models/claude-haiku-5-5.md) for 1-hour cache write prices and tier rules.

### Cache Pricing Notes
-- **Cache Write:** The cost when tokens are first written into the prompt cache. Most providers charge no premium and use the same rate as standard input pricing. Claude models and GPT-5.6 models apply a 25% premium on cache writes.
+- **Cache Write:** The charge for tokens written into the prompt cache; rates depend on the model and cache lifetime. For the GPT-5.6, GPT-6, and GPT-6.1 models listed above, 30-minute writes cost 1.25x the applicable input rate and 12-hour writes cost 2.5x, replacing the ordinary input charge for those tokens. See each model detail page for other models' write rates and lifetime rules.
- **Cache Read:** The discounted cost when cached tokens are reused in subsequent requests.
- **Example with Caching:** If you use Claude Sonnet 4.6 with 1000 tokens cached:
- First request (cache write): `1000 × 3.75 = 3,750 credits`

+# GPT-6.1 Terra
+
+## 概述
+
+GPT-6.1 Terra 是 OpenAI 于 [2026 年 10 月 26 日发布](https://developers.openai.com/api/docs/changelog)的 GPT-6 系列模型，面向高效视觉推理、精确计算机操作及清晰自然的文本写作。它结合文本与图像理解和可调节推理能力，适合日常专业工作流。在 B.AI 上使用的模型 ID 为 `gpt-6.1-terra`。
+
+## 核心特性
+
+- **视觉推理**：解读商品照片、技术图纸和应用截图，辅助比较与分析。
+- **计算机操作**：配合计算机操作工具浏览界面，并跨应用完成任务。
+- **自然写作**：根据提供的材料起草和修改简洁文本，兼顾受众与表达风格。
+- **可调节推理**：提供包括 `none` 在内的六档推理强度，用于平衡推理深度、响应时间和 Token 消耗。
+- **长工作上下文**：1.05M Token 上下文窗口可容纳大量参考资料及对话历史。
+
+## 适用场景
+
+- **视觉审核与匹配**：将商品图片与目录条目匹配，或对照需求比较技术图纸。
+- **应用工作流**：通过连接的工具完成目标明确的屏幕操作，例如录入信息或更新记录。
+- **商务写作**：将提供的笔记和参考材料整理成简洁的初稿、摘要和修订内容。
+- **范围明确的代码修复**：在需求和验证步骤清晰时，对现有代码进行针对性修改。
+
+## 能力与限制
+
+| 能力 | 说明 |
+| :--- | :--- |
+| **推理** | 支持 `none`、`low`、`medium`（默认）、`high`、`xhigh` 和 `max`。 |
+| **多模态** | 支持文本和图像输入、文本输出；不支持原生音频、视频输入或输出。 |
+| **上下文窗口** | [1,050,000 Token](https://developers.openai.com/api/docs/models/gpt-6.1-terra)，由输入和生成的 Token 共同占用。 |
+| **最大输出** | 128,000 Token，包含推理和可见输出。 |
+| **工具使用** | 通过 Responses API 中的工具支持函数调用、网页与文件搜索、计算机操作、代码执行、MCP 和图像生成。 |
+| **结构化输出** | 支持 Structured Outputs 和流式输出。 |
+| **提示词缓存** | 通过 Responses API 支持隐式和显式缓存，最低有效期为 30 分钟或 12 小时。 |
+| **知识截止时间** | 2026 年 6 月 1 日。 |
+
+### 已知限制
+
+- 工具调用需要使用 Responses API；Chat Completions 支持不含工具的请求。
+- 启用推理时，不支持 `temperature`、`top_p` 和对数概率控制；不支持微调。
+- 推理可能增加延迟，并在生成完整可见回答前消耗输出预算。
+- 对于复杂项目和高难度分析，GPT-6.1 Sol 或 GPT-6 Astra 可能更合适。

### 缓存定价说明
-- **缓存写入（Cache Write）：** 当 token 首次写入 Prompt Cache 时产生的消耗。大多数提供方不会额外加价，通常与标准输入价格一致。Claude 模型和 GPT-5.6 模型的缓存写入会在对应输入价格基础上增加 25%。
+- **缓存写入（Cache Write）：** 当 Token 首次写入 Prompt Cache 时产生的费用，单价取决于模型及缓存时长。上述 GPT-5.6、GPT-6 和 GPT-6.1 型号的 30 分钟写入为对应输入价的 1.25 倍，12 小时为 2.5 倍，均替代对应 Token 的普通输入费用。其他模型的写入价格与时长规则请查看对应详情页。
- **缓存读取（Cache Read）：** 后续请求复用缓存 token 时产生的折扣消耗。
- **缓存示例：** 如果你使用 Claude Sonnet 4.6，并有 1000 个 token 被缓存：
- 首次请求（缓存写入）：`1000 × 3.75 = 3,750 credits`
