Nvidia has released Nemotron 3.5 Lightning, an open 30-billion-parameter AI agent model, plus NeMo Switchyard, a router that cuts task costs to about a third of using Opus 4.8 alone.
Read more →River AI, a startup founded by former xAI leader Igor Babuschkin, has raised $1.1 billion to let users train and own their own AI models instead of renting access to closed ones.
Read more →Y Combinator released QM, an MIT-licensed tool it built to run AI agents across its own accounting, legal, and engineering teams, so any company can now self-host it.
Read more →DeepSeek's official V4-Flash-0731 release outperforms its larger V4-Pro model on coding and agent benchmarks, despite activating far fewer parameters per token.
Read more →LG AI Research released K-EXAONE 2.0, a 750-billion-parameter open-weight model under the Apache 2.0 license, aiming to rival Chinese and US frontier AI labs.
Read more →Anthropic CEO Dario Amodei said in a July 27 blog post that the company has never called for banning open-weight AI models, urging chip controls and mandatory safety testing instead.
Read more →Ant Group's Ling-3.0-Flash matches models several times its size on reasoning and coding benchmarks using just 5.1 billion active parameters, the company says.
Read more →Beijing-based Moonshot AI has published the full open weights for Kimi K3, a 2.8-trillion-parameter model it calls the largest open model released to date.
Read more →Poolside's new 118-billion-parameter Laguna S 2.1 matches or beats far larger rivals on agentic coding benchmarks and ships under an open license.
Read more →Nvidia CEO Jensen Huang used his first-ever X post to unveil a letter — now signed by 50 firms including Google, Meta and OpenAI — urging Washington not to restrict open-weight AI models.
Read more →APEC ministers from the US, China and 19 other Asia-Pacific economies adopted the Chengdu Statement on July 23, backing open-source AI paired with stronger security safeguards.
Read more →China's Moonshot AI released Kimi K3, a 2.8-trillion-parameter open model with a 1-million-token context window — a system the company calls the world's first open 3-trillion-class AI model.
Read more →PrismML has released Bonsai 27B, a 27-billion-parameter open-weight model compressed to under 4GB, small enough to run natively on a phone while keeping most of its reasoning ability.
Read more →Mira Murati's startup released Inkling, a 975-billion-parameter open-weight model built for developers to fine-tune and adapt, rather than to top leaderboards.
Read more →Ollama, the open-source tool for running AI models locally, has raised $65 million in Series B funding, bringing total funding to $88 million as its developer base nears 9 million.
Read more →Z.ai has released GLM-5.2, a 744-billion-parameter open-weight model that matches GPT-5.5 on key benchmarks and trails Claude Opus 4.8 narrowly — trained entirely on Huawei silicon with no Nvidia hardware.
Read more →Mistral's new open-source model for Lean 4 fully saturates the miniF2F theorem benchmark, solves 87% of graduate-level math tests, and found five previously unknown bugs in production code — at roughly $4 per proof versus $300 for competing systems.
Read more →Together AI closed an $800 million Series C led by Aramco Ventures, more than doubling its valuation to $8.3 billion as industry-wide use of open AI models has tripled over the past year.
Read more →Chinese technology company Meituan has released LongCat-2.0, a 1.6-trillion-parameter coding model trained entirely on domestic Chinese chips, under the MIT License — the first frontier-class open-source model built without Western semiconductors.
Read more →OpenAI on June 22 expanded its Daybreak security program with GPT-5.5-Cyber, a model designed to detect and patch code vulnerabilities, and launched Patch the Planet to harden over 30 major open-source projects.
Read more →Liquid AI released LFM2.5-230M, a 230-million-parameter open-weight model that runs AI agent tasks at 213 tokens per second on a phone CPU and 42 tokens per second on a Raspberry Pi — without a cloud connection.
