    开源模型LongCat-2.0在Duck Hunt游戏编程测试中与GPT-5.5表现相当,但成本为零。测试由atomic.chat使用kilocode CLI的agent完成,双方均需在三次agent迭代内构建并改进同一游戏(含鸭子、波浪、弹药、物理碰撞、掉落动画和狗回收循环)。LongCat-2.0本地运行70.3K token($0),GPT-5.5云端运行64.9K token($0.65)。美团将其列为1.6T参数MoE,每token约48B active。结果证明,对于小型明确任务,本地开源模型质量已可接近前沿云模型,主要差异转向成本。

    Open-weight LongCat 2.0 matched GPT-5.5 level on agentic game dev for $0! We ran Meituan's LongCat 2.0 against cloud frontier GPT-5.5 in @kilocode CLI with their agent. Same task for both - build a retro Duck Hunt game in one game.html, improved over 3 agent iterations with duck waves, ammo and physics Outputs: LongCat 2.0: 70.3K tokens, $0.00 GPT-5.5: 64.9K tokens, $0.65 LongCat kept up on graphics, physics and game logic. Ducks fly and fall when hit, the dog fetches them, ammo counts down, the waves keep coming. Both ran clean and nothing clipped. The only difference was the bill - GPT cost $0.65, LongCat ran local for $0

    Krea 2 的身份保留功能已发布,配套模型和 ComfyUI 节点也已上线。🔥

    这正是我渴望的那种 ID 保留类功能。 我明天要出行,所以没法测试它。我很好奇它在风格化角色上的效果如何…… https://huggingface.co/conradlocke/krea2-identity-edit https://github.com/lbouaraba/comfyui-krea2edit

    推荐理由:Krea 2的ID保持终于被社区做出来了,附带ComfyUI节点,想稳定控制角色一致性的人可以立刻用起来。

    在atomic.chat桌面应用的物理模拟测试中,腾讯混元Hy3仅用29,757 tokens(成本$0.006)即实现与Gemini 3.5(23,300 tokens,$0.21)相当的保龄球、空气曲棍球和台球HTML5 Canvas物理效果,碰撞与动量传递真实无穿模。GLM-5.2(25,454 tokens,$0.07)编码能力较强但物理表现一般;DeepSeek-V4消耗50,600 tokens($0.009)却输出最弱的物理场景。

    New Hunyuan Hy3 hits Gemini 3.5 quality on physics for 35x cheaper! We gave 4 models the same prompt: build three self-contained HTML5 canvas scenes with real physics demos Prompts: - A bowling ball knocking down the pins - An air hockey rally that ends in a goal - A pool break scattering the rack Outputs: Hunyuan Hy3: 29,757 tokens, $0.006 Gemini 3.5: 23,300 tokens, $0.21 GLM-5.2: 25,454 tokens, $0.07 DeepSeek-V4: 50,600 tokens, $0.009 Tencent's Hy3 matched Gemini across all three: clean collisions, the puck bounced true, the pins scattered like a real strike, the rack broke with real momentum, nothing clipped or floated. GLM is genuinely strong on pure coding tasks, but the moment the job steps outside clean code it gives way. DeepSeek was the letdown, it burned the most tokens of anyone (50k, almost 2x Hy3) and still turned in the weakest scenes

    Ethan Mollick 提出“Encounter Test”作为 AI 的极客基准:让 AI 模拟两个 D&D 生物(灵吸怪 vs. 卓尔武士)对战,观察多久出错。此前测试中 GPT-4o 表现最佳,Gemini 表现有趣。不到 2 年后,借助 Fable 实现了更完整的模拟——设定初始属性、模拟每步动作(含先攻、掷骰),从 60 英尺距离开始,并以 3D 仿真展示结果。

    I propose the Encounter Test as a nerdy benchmark standard for AI. Ask an AI to simulate an encounter between two D&D creatures & see how long it takes to mess up. Drow vs. mind flayer: GPT-4o does best, Gemini is cute. Outcomes similar (I am sure better prompting would help)

    Ethan Mollick 反复要求 Claude Fable 把游戏做得“更 AAA”。Claude 的理解是升级图形、Boss 战、新机制并添加自定义音效与配乐,直至 WebGL 极限。结果 Fable 又自行加入了战利品箱、EULA、成就、无用图形设置和复杂启动画面等典型 AAA 元素,Mollick 强调所有想法都来自 Fable 而非自己。

    引用Ethan Mollick@emollick

    I kept asking Claude Fable to make the game "more AAA" over and over again. The results are... interesting. In Claude's view, this meant upgrading graphics, boss fights, mechanics adding custom sounds and soundtracks until it reached the limits of WebGL. https://swapshot-arena.netlify.app/

    用户 @bridgemindai 披露一次编码会话花费 $321,其中 Fable 5 仅完成 $78(约 25%),而 Opus 4.8 被回退调用完成 $242(约 75%)。原因在于 Fable 5 的新分类器将常规编码提示误判为网络安全风险,导致大部分工作自动路由到更昂贵的 Opus 模型。Anthropic 曾称仅极少数任务会触发 fallback,但该用户实际体验与此不符。

    引用BridgeMind@bridgemindai

    I just paid $321 for a coding session where Fable 5 refused to do the work. Here is where the work actually went: Fable 5: $78 Opus 4.8: $242 75% of the session got routed to Opus because the new classifiers kept flagging routine coding work as cybersecurity risk. The model I chose did a quarter of the job. The fallback did the rest. Anthropic said a small fraction of tasks would fall back. My receipts say otherwise.
