Cursor admits its new coding model was built on top of Moonshot AI’s Kimi

Published by skeptic

AI coding company Cursor launched a new model this week called Composer 2, which it promoted as offering “frontier-level coding intelligence.”  However, an X user posting under the name Fynn soon claimed that Composer 2 was “just Kimi 2.5” with additional reinforcement learning — Kimi 2.5 being an open source model recently released by Moonshot AI, a Chinese company backed by Alibaba and HongShan (formerly Sequoia China).  As evidence, Fynn pointed to code that seemed to identify Kimi as the model. “[A]t least rename the model ID,” they scoffed. It was a surprising revelation, since Cursor is a well-funded U.S. startup that raised a $2.3 billion round last fall at a $29.3 billion valuation, and is reportedly exceeding $2 billion in annualized revenue. Also, the company didn’t mention anything about Moonshot AI or Kimi in its announcement. However, Cursor’s vice president of developer education Lee Robinson soon acknowledged, “Yep, Composer 2 started from an open-source base!” But he said, “Only ~1/4 of the compute spent on the final model came from the base, the rest …

Kimi Antonelli makes history with Chinese GP pole after George Russell’s issues

Kimi Antonelli makes history with Chinese GP pole after George Russell’s issues

Published by Sam Flores

But nor should Antonelli’s achievement be diminished. The Italian’s new record – he is 19 years and 212 days old – smashed the previous record held by Sebastian Vettel, who was 21 years and 72 days old when he took his maiden pole position at the 2008 Italian Grand Prix. And he deserves immense credit for it. That crash last weekend, which Wolff joked made his drive look like “a Lego F1 car”, smashed into a million pieces, would have destroyed some drivers. As would the crash at Monza a few laps into his first free practice session a couple of years ago. But Antonelli clearly has something special. Yes, his debut season was raw. Very raw at times. Antonelli went on a run of four non-finishes in six rounds at one point last year, plus an 18th in Monaco, going into a bit of a tailspin. The scenes in the latest series of Drive to Survive, in which he admits to feelings of self-doubt and shows incredible vulnerability and humility, are some of the …

Kimi K2.5 vs Top Models : Agent Tasks, Benchmarks & Costs

Kimi K2.5 vs Top Models : Agent Tasks, Benchmarks & Costs

Published by skeptic

What if the future of AI wasn’t locked behind paywalls or limited to corporate giants? What if it was in your hands, ready to tackle your most complex projects without breaking the bank? Matthew Berman outlines how the newly released Kimi K2.5 is doing just that, redefining what’s possible with open source artificial intelligence. With its ability to seamlessly process text, images, and videos, Kimi K2.5 isn’t just another incremental update, it’s a bold leap forward. From automating intricate workflows to orchestrating up to 100 sub-agents simultaneously, this model promises not only to save time but to fundamentally reshape how we approach problem-solving in both creative and technical fields. And the kicker? It’s designed to be accessible, affordable, and endlessly customizable. In this overview, we’ll explore how Kimi K2.5’s multimodal intelligence is unlocking new possibilities, from crafting polished presentations to interpreting complex datasets with precision. You’ll also discover why its agent swarm orchestration system is a fantastic option for efficiency, delivering results at speeds that outpace even the most advanced proprietary models. But it’s not …

Moonshot’s Kimi K2.5 is ‘open,’ 595GB, and built for agent swarms — Reddit wants a smaller one

Moonshot’s Kimi K2.5 is ‘open,’ 595GB, and built for agent swarms — Reddit wants a smaller one

Published by skeptic

Two days after releasing what analysts call the most powerful open-source AI model ever created, researchers from China’s Moonshot AI logged onto Reddit to face a restless audience. The Beijing-based startup had reason to show up. Kimi K2.5 had just landed headlines about closing the gap with American AI giants and testing the limits of US. chip export controls. But the developers waiting on r/LocalLLaMA, a forum where engineers trade advice on running powerful language models on everything from a single consumer GPU to a small rack of prosumer hardware, had a different concern. They wanted to know when they could actually use it. The three-hour Ask Me Anything session became an unexpectedly candid window into frontier AI development in 2026 — not the polished version that appears in corporate blogs, but the messy reality of debugging failures, managing personality drift, and confronting a fundamental tension that defines open-source AI today. Embedded Reddit Post Moonshot had published the model’s weights for anyone to download and customize. The file runs roughly 595 gigabytes. For most of …

How Moonshot’s Kimi K2.5 helps AI builders spin up agent swarms easier than ever

How Moonshot’s Kimi K2.5 helps AI builders spin up agent swarms easier than ever

Published by skeptic

Chinese company Moonshot AI upgraded its open-sourced Kimi K2 model, transforming it into a coding and vision model with an architecture that supports an agent swarm orchestration.  The new model, Moonshot Kimi K2.5, is a good option for enterprises that want agents that can automatically pass off actions instead of having a framework be a central decision-maker. The company characterized Kimi K2.5 as an “all-in-one model” that supports both visual and text inputs, letting users leverage the model for more visual coding projects. Moonshot did not publicly disclose K2.5’s parameter count, but the Kimi K2 model that it’s based on, had 1 trillion total parameters and 32 billion activated parameters thanks to its mixture-of-experts architecture. This is the latest open-source model to offer an alternative to the more closed options from Google, OpenAI, and Anthropic, and it outperforms them on key metrics including agentic workflows, coding, and vision. On the Humanity’s Last Exam (HLE) benchmark, Kimi K2.5 scored 50.2% (with tools), surpassing OpenAI’s GPT-5.2 (xhigh) and Claude Opus 4.5. It also achieved 76.8% on SWE-bench …
