Nvidia-backed cloud startup Fireworks AI raises $1.5 billion at a $17.5 billion valuation after surging to over $1 billion in annualized revenue — a fivefold jump — fueled by surging corporate demand for cheaper, open-source AI models as it processes 40 trillion tokens daily at costs up to ten times lower than closed competitors.
Mira Murati's Thinking Labs debuts Inkling, a massive 975-billion-parameter open-weight AI model capable of reasoning across text, images, and audio with a one-million token context window, but it immediately faces stiff competition from Chinese labs like Kimi, whose K3 model boasts 2.8 trillion parameters and already outperforms it on benchmarks.
OpenAI's CLIP neural network matches ResNet50's ImageNet performance with zero labeled training data, marking a major breakthrough in computer vision by using natural language instructions instead of task-specific optimization.
A new open-source Python tool called 'mind' brings human-like memory to AI coding agents using spreading-activation recall and Ebbinghaus forgetting curves — all in a single, zero-dependency file — achieving perfect recall benchmarks with sub-14ms latency across graphs of up to 1,000 nodes.
Vercel opens its AI Gateway leaderboard data to the public under the Creative Commons CC BY 4.0 license, enabling free commercial use of model, lab, app, and provider performance data via daily-updated CSV downloads and a public API endpoint.
xAI launches Grok Build, an open-source Rust-based AI coding agent with terminal UI support for file editing, shell commands, and web search — already surpassing 10,000 GitHub stars despite rejecting all external contributions.
A new open-source project called Spectacles Dimensional OS now lets users control real Unitree robots in real-time using Snap Spectacles AR headsets, featuring manual spatial navigation and an AI-powered voice command mode backed by OpenAI.
A free reinforcement learning book, 'The Little Book of Reinforcement Learning,' launches on GitHub, offering PyTorch implementations of algorithms from Monte Carlo methods to PPO, complete with proofs and explanations, available under a Creative Commons license with more content coming soon.
Reflection AI, an $8 billion open-model startup, secures a massive $1 billion compute deal with Nebius, gaining access to cutting-edge Nvidia chips as AI companies intensify their race to lock down critical computing infrastructure.
Open Interpreter is back as a fork of OpenAI's Codex, now boasting 64,900 GitHub stars, a lightweight Rust-based architecture, computer use capabilities, and support for top open models like DeepSeek and Kimi across macOS, Linux, and Windows.
