Ai2 Open-Sources MolmoMotion, a Model That Forecasts 3D Object Motion From Language Instructions, With a 1.16-Million-Video Dataset
The Allen Institute for AI released MolmoMotion, an open model that predicts an object's future 3D trajectory from a video, marked points, and a language instruction, plus a 1.16-million-video training dataset and a new benchmark.
Meituan Open-Sources LongCat-2.0, a 1.6-Trillion-Parameter Coding Model It Says Was Trained End-to-End on Chinese Chips
Meituan released LongCat-2.0, a 1.6T-parameter MoE model under an MIT license, claiming it is the first trillion-parameter model trained and served entirely on domestic ASICs.
ByteDance Releases Seed 2.1 Pro and Turbo, Claiming It Matches Claude Opus 4.6 on Coding at Roughly 80 Percent Lower Cost
ByteDance unveiled its Seed 2.1 Pro and Turbo models at the Volcano Engine FORCE conference, claiming leading coding and agent benchmarks and a total cost of ownership close to 80 percent below Claude Opus 4.6.
Anthropic Launches Claude Sonnet 5, a Cheaper Agentic Model It Says Approaches Its Opus 4.8 Flagship
Anthropic's midsize model matches near-flagship agentic performance at a fraction of the price, and arrives as the lab lifts controls on Fable 5.
Liquid AI's 230M-Parameter LFM2.5 Beats Models Four Times Its Size at Data Extraction and Runs on a Raspberry Pi
The MIT spinout's smallest model yet pairs convolution and attention blocks to outscore billion-parameter rivals on data extraction while decoding at 42 tokens per second on a Raspberry Pi 5.
Zhipu Releases GLM-5.2, a 744-Billion-Parameter Open Coding Model, Days After Washington Cut Off Foreign Access to Anthropic's Claude
Zhipu's GLM-5.2 ships under an MIT license as a frontier coding alternative just after the US barred foreign nationals from Anthropic's Fable 5 and Mythos 5.
MIT's Recursive Language Models Let an LLM Read Its Own Prompt as Code, Beating Frontier Long-Context Scaffolds
A new MIT CSAIL inference method has a model inspect its prompt in a Python REPL and recursively call itself over snippets, processing inputs beyond its context window.
Moonshot AI Open-Sources Kimi K2.7-Code, a Trillion-Parameter Coding Model That Cuts Reasoning Tokens by 30%
Moonshot AI released Kimi K2.7-Code, an open-weight 1-trillion-parameter MoE coding model under a Modified MIT License, claiming roughly 30% lower thinking-token usage than K2.6 on self-run benchmarks.
Anthropic Releases Claude Fable 5, Its First Public Mythos-Class Model, With Sensitive Queries Routed to Opus 4.8
Anthropic launched Claude Fable 5 on June 9, a public version of its restricted Mythos model that falls back to Opus 4.8 on high-risk topics in under 5% of sessions.
Microsoft Launches Seven In-House MAI Models, Built From Scratch Without Distillation to Cut OpenAI Reliance
Microsoft unveiled seven proprietary MAI models led by the 35B-active reasoning model MAI-Thinking-1, all trained from scratch without distillation as it reduces its dependence on OpenAI.
NVIDIA Open-Sources Nemotron 3 Ultra, a 550B Mamba-Transformer Mixture-of-Experts Built for Long-Running Agents
The 550-billion-parameter model activates 55 billion parameters per token, ships under the Linux Foundation's OpenMDW-1.1 license, and trades blows with China's Kimi-K2.6 on coding benchmarks.
Google Releases Gemma 4 12B, an Encoder-Free Multimodal Model With Native Audio That Runs on a 16GB Laptop
Google's new 12-billion-parameter open model drops separate vision and audio encoders, projecting raw image patches and audio waveforms straight into the LLM, and ships under Apache 2.0.
