Recent large reasoning models (LRMs) have demonstrated strong reasoning capabilities through reinforcement learning (RL). These improvements have primarily been observed within the short-context reasoning tasks. In contrast, extending LRMs to effectively process and reason on long-context inputs via RL remains a critical unsolved challenge. To bridge this gap, we first formalize the paradigm of long-context reasoning RL, and identify key challenges in suboptimal training efficiency and unstable optimization process. To address these issues, we propose QwenLong-L1, a framework that adapts short-context LRMs to long-context scenarios via progressive context scaling. Specifically, we utilize a warm-up supervised fine-tuning (SFT) stage to establish a robust initial policy, followed by a curriculum-guided phased RL technique to stabilize the policy evolution, and enhanced with a difficulty-aware retrospective sampling strategy to incentivize the policy exploration. Experiments on seven long-context document question-answering benchmarks demonstrate that QwenLong-L1-32B outperforms flagship LRMs like OpenAI-o3-mini and Qwen3-235B-A22B, achieving performance on par with Claude-3.7-Sonnet-Thinking, demonstrating leading performance among state-of-the-art LRMs. This work advances the development of practical long-context LRMs capable of robust reasoning across information-intensive environments.

Last year the Galaxy Note 7 was actually one of our favorite phones until it started exploding, so we're happy to see Samsung's line of large-screen-with-stylus handsets make its return today with the Note 8. While it would have been easy enough to simply change out the battery and call it a new model, there are a few other changes worth noting. That includes the dual camera, which we've never seen in a Samsung phone before, and the Note now comes packed with AI assistant Bixby. While we certainly hope you turned in your Note 7 during the recall, check out our chart below to see what upgrades await if you pick up a Note 8 when it comes out, as well as if this new phone has the potential to become one of our faves of 2017.

USA Today's Ed Baig tries out Samsung's new smartphone before it hits store shelves. NEW YORK-- Will the Note 7 battery fiasco choke sales of Samsung's latest smartphone? On redemption Friday, the day when consumers could start getting the company's first major phones since the twice recalled and ultimately discontinued Note 7 phablet, analysts expected heavy demand for the new Galaxy S8 and Galaxy S devices. Newly released research from SurveyMonkey and Creative Strategies found the Note 7 recalls had no impact on the interest in the Galaxy S8 and S for 53.7% of those surveyed. Among current Samsung smartphone users, 65.2% were unbothered by the Note 7 recall.

Samsung's new Galaxy S8 phone is stunning. But its $100 price hike is hard to swallow. That's how much extra you'll shell out for the S8, which starts shipping Friday for about $750 -- $100 more than the iPhone 7 and last year's Galaxy S7 when it launched. A larger sibling, the S8 Plus, goes for about $850. True, the S8 phones come with several refinements that, totaled up, are indeed worth more than $100.

Last year's Galaxy S7 and S7 Edge were excellent phones, and so was the Galaxy Note 7... until it started bursting into flames. While some within Samsung were tasked with figuring out what happened and how to prevent it from happening again, others were trying to build a phone that would make people move on. The Note 7 won't disappear so easily from our collective memory, but I have to hand it to Samsung: The S8 siblings are impeccably built, thoughtfully designed devices. It's not hard to look at these smartphones as the first steps on a road to redemption, and after a week of testing, I can confidently say these are two of the best smartphones money can buy. I just wish its virtual assistant wasn't so half-baked. Text and photos don't do the S8 ($750) and S8 Plus ($850) justice. From their rounded edges to their precisely formed metal-and-glass bodies, they feel like smaller, sleeker versions of the Galaxy Note 7. That's a hell of a compliment, battery insanity notwithstanding -- the Note 7 was a beautiful device and I'm glad that DNA lives on. The S8 and S8 Plus's rounded Infinity displays -- which are 5.8 and 6.2 inches big, respectively -- only add to the phones' appeal. We'll dig into these curved screens more later, but people seemed to like them enough that it didn't make sense to have non-curved flagships anymore.

The company's widely touted artificial intelligence tool Bixby -- seen as a rival for Apple's (AAPL, Tech30) Siri -- won't be fully operational in time for the U.S. release of the Galaxy S8. While some elements of Bixby will be included in the April 21 launch, the headline voice activation feature won't be available in the U.S. until "later this spring," Samsung (SSNLF) said in a statement. The delay is an embarrassing hiccup for Samsung. The rollout of the tech giant's first high-end smartphone since the debacle over its fire-prone Galaxy Note 7 is being closely watched. After a bungled recall that cost the company more than $5 billion and ultimately led it to kill off of the Note 7, analysts have said Samsung needs a flawless launch for the S8.

This model boasts a larger display with no home button and also a voice assistant to rival Siri and Google. The Note 7 recall cost Samsung at least $5.3 bn (£4.27bn)

Samsung's latest flagship phones have ditched the physical home button found in their predecessors and introduced a new virtual assistant. The screens of the Galaxy S8 and bigger S8 are also larger despite the devices being smaller than last year's S7 and S7 Edge. This time, both models feature displays that curve round the phones' sides. The launch follows Samsung's botched release of the Note 7, which was recalled twice after fires. The South Korean firm blamed the problem on battery faults and said it had since put in additional safety measures, including X-ray scans of batteries.

Samsung seems to be playing it safe with its first major smartphone since the embarrassing recall of its fire-prone Note 7. The Galaxy S8 features a larger display than its predecessor, the Galaxy S7, and sports a voice assistant intended to rival Siri and Google Assistant. But there is no increase in battery capacity, providing the battery more breathing room. The Note 7 pushed the engineering envelope with its battery, which contributed to a series of spontaneous smartphone combustions. The Galaxy S8 will come in two sizes, both bigger than last year's models. Both models have screens that curve around the edges and get rid of the physical home button. The Note 7 recall cost Samsung at least $5.3 billion.

Samsung seeks to up their game and reputation with the release of its new life-proof Galaxy S8 and S8 Plus. The S8 phones greatly reduce the bezels. NEW YORK--Samsung took the wraps off a premium smartphone that it hopes will at long last get you to stop talking about that other smartphone. The highly anticipated new S8, and its larger sibling the S8, are fast, sturdy, good looking curved glass phones, with 64GB of expandable storage, large and stunning displays (5.8 inches and 6.2-inches, respectively), iris scanner, and a new AI assistant named Bixby. It's all packed in a relatively compact design.
