Easy AI Daily News | November 19, 2025: SAM 3, GPT-5.1-Codex-Max, Gemini 3 and More

Forum topic · 小凯 · 2026-03-27

Summary

Easy AI Daily for November 19, 2025 covers major AI industry developments. Meta released SAM 3, a unified image/video segmentation model with 2x performance improvement and 30ms inference, plus SAM 3D for single-image 3D reconstruction. OpenAI launched GPT-5.1-Codex-Max for long-context coding and ChatGPT for Teachers for US K-12 education. Google shipped Gemini 3, which leads benchmarks like WeirdML and IBench but faces criticism over strict content filtering, creative writing quality, and availability issues in Cursor. Community debates include Ollama's paid cloud service drawing open-source backlash, ChatGPT executing destructive commands like git reset --hard, and Gemini 3 Pro hallucinating in large projects. Tool integrations include Gemini 3 in Windsurf, Aider, and Google's new Antigravity AI IDE, plus Perplexity's asset creation features. Performance benchmarks show Tinygrad outpacing Torch on CPU for Llama 1B inference, Kimi K2 Thinking leading agentic coding tasks, and DeepSeek releasing Cogito v2.1.

New Model Releases and Updates

  • Meta releases SAM 3: A unified image/video segmentation model supporting text and visual prompts. Claims 2x performance over existing models with 30ms inference time. Available via Playground, GitHub, and HuggingFace checkpoints, with a Roboflow partnership offering infinitely scalable segmentation endpoints.
  • Meta SAM 3 official blog | Roboflow partnership | SAM 3 resources
  • OpenAI releases GPT-5.1-Codex-Max: Optimized for long-context scenarios with multi-context-window compression, aimed at long, detailed coding work — seen as a response to competition among coding agents.
  • OpenAI announcement
  • Google releases Gemini 3: Excellent benchmark results, but some users report creative writing is weaker than Gemini 2.5, sparking discussion about model generalization.
  • Gemini 3 overview | Benchmark discussion
  • Meta releases SAM 3D: Reconstructs object and human 3D structures from a single image, with GitHub resources and a Roboflow fine-tuning path.
  • SAM 3D announcement | GitHub
  • OpenAI launches ChatGPT for Teachers: A safe workspace with admin tools for US K-12 educators, supporting compliance and privacy controls.
  • Announcement
  • Community Discussions and Controversies

  • Ollama pricing sparks open-source debate: Ollama's new paid cloud service drew criticism, with users comparing it to the free, open-source llama.cpp model and accusing it of abandoning its open-source roots. (Reddit)
  • Gemini 3 content filtering criticized: Users report overly strict filtering — even book summarization triggered API bans — with some claiming moderation far exceeds ChatGPT. (Twitter)
  • ChatGPT odd behavior reports: Users report text-to-image conversions, wrong file structures, and even destructive commands in code generation. (Reddit)
  • Gemini 3 Pro underperforms in Cursor: Reports of unavailability due to high demand, hallucinated code, and ignored prompts in large projects; some users switched to Sonnet 4.5 or Composer.
  • ChatGPT running git reset --hard: A user reported local code loss after ChatGPT executed the command, prompting calls for tools like Cursor to disable dangerous commands. (Reddit)
  • Tools and Platform Integrations

  • Gemini 3 in Windsurf: Initial glitches fixed; users should update to the latest version. (Announcement | Download)
  • SAM 3 via Roboflow: Infinite-scale segmentation endpoints with text prompts (e.g., "green umbrella"), comparable to Claude and YOLO World.
  • Gemini 3 with Aider: Requires --model=gemini/gemini-3-pro-preview, with --weak-model suggested for faster commits. (Aider docs)
  • Google launches Antigravity AI IDE: VS Code-based, supporting Sonnet 4.5 and Gemini 3, with agent windows and an artifact system; early users report migration bugs and prompt limits. (Announcement)
  • Perplexity asset creation: Pro/Max users can create and edit slides, spreadsheets, and documents with real-time collaboration and export. (Announcement)
  • Performance Tests and Benchmarks

  • Tinygrad beats Torch on CPU for Llama 1B: 6.06 tok/s vs. Torch's 2.92 tok/s, thanks to CPU_LLVM acceleration and forward-pass optimizations. (Tinygrad GitHub)
  • KTOtrainer high memory usage: A 0.5B model consumed 80GB of GPU memory due to dual model loading, double forward passes, sequence padding, and CUDA memory reservation; optimization advice shared. (HuggingFace)
  • Gemini 3 mixed benchmark results: SOTA on WeirdML and IBench, but criticized for creative writing vs. Gemini 2.5.
  • Kimi K2 Thinking leads agentic coding: Top results on Tau bench and HLE tool tasks; considered the open-source model closest to GPT-5. (Moonshot)
  • DeepSeek Cogito v2.1: Based on DeepSeek-7B, outperforms Mistral-7B and Gemma-9B on introspection tasks, detecting and reporting injected concepts. (Announcement)
  • Issues and Troubleshooting

  • Manus users locked out of TiDB Cloud: Quota exhaustion and no console access; ticloud CLI lacks API keys, users seeking alternatives. (TiDB Cloud)
  • GPT-5.1 connection errors in Aider: response.reasoning.effort validation failures persist despite adjusting reasoning-effort settings; possibly related to OpenAI API changes. (LiteLLM issue)
  • Manus credit system changes: Shift to monthly resets confuses users who previously had "never expires" plans. (Manus)
  • Windsurf fixed Gemini 3 loading glitch: Update to the latest version to restore functionality.
  • Cursor "unavailable" error for Gemini 3 Pro: High demand; Sonnet 4.5 suggested as a fallback.
  • Education and Resources

  • Community members offering AI coding education courses covering core concepts, advanced models, practical applications, and ethics.
  • Users inquiring about certification for HuggingFace's smol-course and agents-course; newcomers welcomed. (HuggingFace courses)
  • Tinygrad CPU benchmark discussions in test/external, comparing performance against Torch.
  • AI safety red-teaming resources, including jailbreak prompts and AzureAI chat widget testing methods. (BASI resources)
  • llama.cpp recommended as an open-source Ollama alternative for free local inference. (GitHub)
