Meituan has open-sourced LongCat-2.0, a 1.6 trillion-parameter Mixture-of-Experts model with a native 1-million-token context window, released on June 30, 2026 under a permissive MIT license. It is the model that quietly topped global developer charts on OpenRouter for two months under the codename “Owl Alpha”, and Meituan says it is the first trillion-parameter model trained […]

GLM is the family of large language models built by Zhipu AI, the Chinese lab now trading as Z.ai. If you typed “what is GLM” expecting the statistics term or the Bosch laser measure, this is the other one: GLM is a direct open-weight rival to ChatGPT, Claude and Gemini, and its current flagship GLM-5.2 […]

Most AI models people call “open source” are not actually open source. They are open-weight, a narrower thing, and the gap between the two decides what you can legally do with a model, how much you can trust it, and whether anyone could ever rebuild it. In October 2024 the Open Source Initiative finally drew […]

The best open source AI models now score within single digits of GPT-5.5 and Claude Opus 4.8 on most benchmarks, and you can download their weights for free. GLM 5.2 posts a 62.1 on SWE-bench Pro, DeepSeek V4 hits 80.6 on SWE-Bench Verified, and Gemma 4 runs on a laptop while scoring 85.2% on MMLU-Pro. […]

Update, June 21, 2026: The first independent benchmarks have landed since launch and now rank GLM 5.2 as the strongest open-weight coding model, and the open weights are available for self-hosting. Scores and analysis are below. GLM 5.2 arrived on June 13, 2026, and it lands with three headline numbers: a 753-billion-parameter Mixture-of-Experts design, a […]

Moonshot AI released Kimi K2.7 Code on June 12, 2026, and it is one of the largest open-weight coding models you can download right now. It packs 1 trillion total parameters, activates 32 billion of them per token, runs a 256K-token context window, and ships with open weights on Hugging Face under a Modified MIT […]

The city government of Rio de Janeiro just released a frontier-class open AI model. It is built to go head to head with the best open systems on the planet. Rio 3.5 Open 397B comes from IplanRIO, the municipal IT company that runs Rio de Janeiro’s digital services. On its own benchmarks it edges out […]

GreenPT runs every conversation on 100% renewable energy inside European data centers, and it claims a 40% lower CO₂ footprint than US hyperscalers. That single promise, sustainable AI chat that keeps your data in the EU, is the whole pitch behind this growing ChatGPT alternative from the Netherlands. This GreenPT review covers what it is, […]

A Chinese AI lab just released a free model that scores 80.8 on SWE-Bench Verified and 75.3 on Terminal-Bench 2.1, putting it in the same league as GPT-5.5 and Claude Opus 4.7 on real coding work. It is called Nex-N2-Pro, it dropped on June 2, 2026, and it costs nothing to download. The model comes […]

On June 4, 2026, NVIDIA released Nemotron 3 Ultra, a fully open 550 billion parameter reasoning model built specifically for long running agents. According to benchmark platform Artificial Analysis, it is now the most capable open model to come out of a US lab, scoring 48 on the Artificial Analysis Intelligence Index. That puts it […]
