Weibo’s new open source AI model VibeThinker-1.5B outperforms DeepSeek-R1 on $7,800 post-training budget
Another day in late 2025, another impressive result from a Chinese company in open source artificial intelligence. Chinese social networking company Weibo’s AI division recently released its open source VibeThinker-1.5B—a 1.5 billion parameter large language model (LLM) that is a fine-tuned variant of rival Chinese tech firm Alibaba’s Qwen2.5-Math-1.5B. It’s available now for free download […]
OpenAI reboots ChatGPT experience with GPT-5.1 after mixed reviews of GPT-5
ChatGPT is about to become faster and more conversational as OpenAI upgrades its flagship model GPT-5 to GPT-5.1. OpenAI announced two updates to the GPT-5 series: GPT-5.1 Instant and GPT-5.1 Thinking. Both models are now accessible on ChatGPT. GPT-5.1 Instant, essentially the default and most-used model, is now “warmer, more intelligent, and better at following […]
Inside LinkedIn’s generative AI cookbook: How it scaled people search to 1.3 billion users
LinkedIn is launching its new AI-powered people search this week, after what seems like a very long wait for what should have been a natural offering for generative AI. It comes a full three years after the launch of ChatGPT and six months after LinkedIn launched its AI job search offering. For technical leaders, this […]
How Deductive AI saved DoorDash 1,000 engineering hours by automating software debugging
As software systems grow more complex and AI tools generate code faster than ever, a fundamental problem is getting worse: Engineers are drowning in debugging work, spending up to half their time hunting down the causes of software failures instead of building new products. The challenge has become so acute that it’s creating a new […]
Baidu just dropped an open-source multimodal AI that it claims beats GPT-5 and Gemini
Baidu Inc., China’s largest search engine company, released a new artificial intelligence model on Monday that its developers claim outperforms competitors from Google and OpenAI on several vision-related benchmarks despite using a fraction of the computing resources typically required for such systems. The model, dubbed ERNIE-4.5-VL-28B-A3B-Thinking, is the latest salvo in an escalating competition among […]
Meta’s SPICE framework lets AI systems teach themselves to reason
Researchers at Meta FAIR and the National University of Singapore have developed a new reinforcement learning framework for self-improving AI systems. Called Self-Play In Corpus Environments (SPICE), the framework pits two AI agents against each other, creating its own challenges and gradually improving without human supervision. While currently a proof-of-concept, this self-play mechanism could provide […]
Only 9% of developers think AI code can be used without human oversight, BairesDev survey reveals
Senior software developers are preparing for a major shift in how they work as artificial intelligence becomes central to their workflows, according to BairesDev’s latest Dev Barometer report published today. VentureBeat was given an exclusive early look and the findings below come directly from that report. The quarterly global survey, which polled 501 developers and […]
Meta returns to open source AI with Omnilingual ASR models that can transcribe 1,600+ languages natively
Meta has just released a new multilingual automatic speech recognition (ASR) system supporting 1,600+ languages — dwarfing OpenAI’s open source Whisper model, which supports just 99. Is architecture also allows developers to extend that support to thousands more. Through a feature called zero-shot in-context learning, users can provide a few paired examples of audio and […]
Chronosphere takes on Datadog with AI that explains itself, not just outages
Chronosphere, a New York-based observability startup valued at $1.6 billion, announced Monday it will launch AI-Guided Troubleshooting capabilities designed to help engineers diagnose and fix production software failures — a problem that has intensified as artificial intelligence tools accelerate code creation while making systems harder to debug. The new features combine AI-driven analysis with what […]
How context engineering can save your company from AI vibe code overload: lessons from Qodo and Monday.com
As cloud project tracking software monday.com’s engineering organization scaled past 500 developers, the team began to feel the strain of its own success. Product lines were multiplying, microservices proliferating, and code was flowing faster than human reviewers could keep up. The company needed a way to review thousands of pull requests each month without drowning […]
