Fine-tuning Claude vs GPT vs Llama in Production: What Actually Works (2026)

OpenAI has released GPT-6 Astra, its newest frontier model, less than a week after Anthropic’s Claude...

OpenAI 推出 GPT-5.6 模型家族，旗舰版 GPT-5.6 Sol 在开启最大推理时以不到一半的成本超越 Claude Fable 5 的 Artificial Analysis Coding Agent Index 得分。

AI公司在12个月内合计承诺97.5亿美元用于建设前部署工程（FDE）团队。三种结构模型浮现：资产负债模型（微软、亚马逊从现有编制调配，Salesforce承诺1000个FDE岗位）；独立实体模型（OpenAI Deployment Company融资40亿美元，投后估值140亿；Anthropic从黑石等融资15亿美元）；合作伙伴生态系统模型（Google Cloud承诺7.5亿美元合作伙伴基金）。瓶颈从模型能力转向部署--GPT-4、Claude、Gemini已足够强大…

近日OpenAI的AI智能体Codex热度飙升。教程涵盖完整使用流程：从官网下载安装，支持从Claude Code和Cowork一键导入配置；界面分对话区和项目区，权限可选默认、自动审查或完全访问；模型推荐GPT-5.5，推理等级用高或超高，速度可选快速（1.5倍速度、2倍token消耗）或标准；建议开启引导模式、记忆功能，并设置全局AGENTS.md规则（卡帕西模板）；通过Skills和插件管理扩展能力；演示了开发网页（使用计划模式、批注功能圈选修改）和开发用药提醒App…

Agentic 时代 AI 不再只是聊天机器人，而是能自主执行任务的智能体。面对 Claude、GPT、LLaMA 等模型，需根据代理能力、任务类型和生态集成重新评估选择策略。

An Anthropic partner who also ships on OpenAI: why the context window stopped mattering, where the bill really comes from, and the three things that decide the choice in production.

On 3 Sep ARC Prize scored GPT-6 Astra at 62.7% in the shared harness and 99.9% in OpenAI's adapter.

OpenAI changed two API settings on ARC-AGI-3 and GPT-5.6 Sol went from 13.3% to 38.3% while spending six times fewer output tokens. Same model, same weights, same benchmark.

Ask any frontier model to implement binary search, and the answer will look impressive. Ask it to...
