It has been great to see the community come together to build with Motif 3 - so we are extending free access on @InfronAI by two weeks, through October 1st. Thank you to everyone who tried it and shared feedback. If you haven’t tried it yet, we’d appreciate giving it a look! 🙇‍♂️
Motif-3 stays FREE on Infron through October 1. No minimum balance. Same API. Try Motif-3: infron.ai/models/motif/motif… Give Motif-3 a task that takes more than one step. Let your agent inspect a repo, run tests, and work through a failure.

Motif 3 is now public and available through an API for the first time. We've been heads-down on research. Now that you can build with it, we'd love to hear where it shines and where we can improve. Your feedback will shape what we build next. Free on @InfronAI through Sep 29.
Motif 3 scores 35.3 on tau-3 Banking, ahead of DeepSeek V4 Pro in @motif_tech's published comparison: infron.ai/models/motif/motif… It activates just 13.2B parameters per token. Free access on Infron. Report and API details in the first reply.

I am told the Hodge Conjecture is very close to being verified by OpenAI, and that one of OpenAI or Anthropic are also close to solving Birch-Swinnerton-Dyer. The race to be 'next' behind the scenes is unlike anything I've had described to me before If true - and it may not be, given the scale of the rumour mill right now - it could mean 3 Millennium Problems fall in the space of a month. Crazy times

While everyone is raging at me for defending OpenAI/Anthropic in one narrow area, we have got loads of new, fun, and powerful open models. A far better place than your attention than frontier lab drama.

글로벌 가장 널리 인정받는 AAII가 한국을 명실공히 AI 레이스 No.3 국가로 인정하고 있습니다. 국가 AI 전략과 #혁신역량 보유 국내 #독파모 기업들이 함께 만든 성과입니다. 앞으로도 규모 무관 가장 혁신적이고 능력과 의지가 있는 기업에 집중 지원 투자해서 경쟁력을 높여가야 겠습니다.
South Korea has once again established a clear #3 position in the global AI race, trailing only the United States and China. The depth and vibrancy of Korea’s AI ecosystem is supported by strong domestic talent, public investment, and the incentives created by Korea’s Sovereign AI Foundation Model project A number of South Korean labs, including Motif Technologies, Upstage, SK Telecom, and LG AI Research, have now scored above 30 on the Artificial Analysis Intelligence Index. This concentration of competitive model developers highlights the growing density of Korea’s domestic AI ecosystem. Among them, Motif Technologies and Upstage have models scoring above 40, making them the highest-scoring models on the Intelligence Index developed outside the United States and China. Leading models from each lab include: ➤ Motif Technologies’ Motif 3 scored 47 on the Intelligence Index (314B total parameters, 13B active; open weights). ➤ Upstage’s Solar Pro 4 scored 42 on the Intelligence Index. It is a proprietary reasoning model. ➤ SK Telecom’s A.X K2 scored 35 on the Intelligence Index (692B total parameters, 33B active; open weights). ➤ LG AI Research’s K-EXAONE 2.0 scored 31 on the Intelligence Index (750B total parameters, 37B active; open weights). Outside the competition, Korea’s model-development ecosystem has continued to broaden. Trillion Labs, Korea Telecom (KT), and other AI labs are building out their own model families, adding to a domestic field that is considerably deeper and more competitive than it was a year ago.

Proud to have @motif_tech’s new model, Motif 3, on our ai& inference platform today. @aiand_ are proud launch partners and excited about where sovereign AI is going. Thanks to the Motif team, my co-founder @hara_shimpei, and all the team for the hard work to make this happen.
Motif 3 is officially here. Today, we’re releasing Motif 3 Base and Motif 3. Motif 3 Base is our pretrained foundation model, while Motif 3 is built on top of it with post-training using NVIDIA NeMo-RL. Both models were developed with the support of Korea's Ministry of Science and trained on NVIDIA B200 GPUs. With Motif 3, we’re taking our first step into the frontier LLM race. There’s still a long way to go, but we believe we’ve built a model that deserves to be in the race. We’ve shared the details in our technical report and blog post. In collaboration with NVIDIA, we’re also releasing an NVFP4 version of Motif 3. All models will be available on Hugging Face. Links are in the comments.
