CURSOR LAUNCHES ORIGIN CODE HOSTING PLATFORM AS GITHUB OUTAGE EXPOSES OPENING IN AI CODING RACE

Cursor is currently rolling out its Origin code hosting platform to paid users. The launch coincided with a GitHub outage that lasted over six hours. Origin allows users to connect GitHub repositories, so they do not have to move platforms. Allowing GitHub to stay as a source of truth means it costs nothing for organizations to try Origin and nothing breaks if it is abandoned.

ANTHROPIC'S REVENUE TO EXCEED $65 BILLION

Anthropic was reportedly on track to exceed $65 billion in annualized revenue based on its current performance, more than seven times its pace at the end of the previous year.

GROQ RAISED $350 MILLION AFTER NVIDIA DEAL

Groq raised $350 million at a $3.5 billion valuation after Nvidia licensed its technology and hired senior members of its team. The remaining company was rebuilding around an inference cloud combining Groq LPUs with Nvidia systems.

WHEN MODELS LEARN

Test-time training allows AI models to adapt by updating their weights during use, similar to a GPS learning a persistent traffic shortcut. This approach reduces memory needs by using a fixed-size set of weights instead of a linearly growing KV-cache but requires separate models for each user, increasing computational demands. The trade-off lies between the efficient handling of long contexts for personalized services and the broader accessibility of standard models.

TESTING FABLE VS SOL IN TERMS OF TASTE (THEY ARE BOTH BAD)

Researchers built a small harness and gave Fable 5 and Sol 5.6 the same jobs to evaluate their taste and creativity. The models had to follow the same creative process to build four different 15-second-long videos - three ads and one mini-documentary. The experiment showed that we are still far from having frontier models building production-ready concepts and videos autonomously. They can be creative and helpful for exploring and refining ideas, but they can't replace human judgment, for now.

QWEN3.8 VS QWEN3.6 VS GEMMA 4 ON A 24GB GPU

A hands-on comparison tested three dense multimodal models under the same 24GB GPU constraint, including memory headroom at longer contexts. The measurements are useful, but Qwen3.8 was already covered, and the source's commercial independence requires validation.

WANT TO OWN YOUR AI? FINE-TUNE GLM-5.2 AND RUN IT ANYWHERE YOU WANT

GLM-5.2 is a long-horizon coding and agentic model that supports 1M-token context and holds onto architectural constraints, API contracts, and prior engineering decisions. Since launch, GLM-5.2 has been available on Crusoe's Serverless Inference [13]. Now you can also use it in SERVERLESS FINE TUNING and SELF-SERVE DEPLOYMENTS. Create a

THE DEADLINE DIVIDEND

Latency measures time to a useful result. Higher speed can finish work sooner, or fit more work before the same deadline. That useful extra work is the deadline dividend. It can be used to fund another strategy, a critic, a verification pass, or recovery after failure.

DIG.BENCH

dig.bench is a benchmark that measures whether an agent can experiment to discover a game's unknown rules. It contains 70 text-based games, 21 that have been publicly released. Progress is scored by whether the game can be beaten within a limited number of steps. Humans can make the discoveries necessary to solve even the hardest games, while the best models struggle to beat games in the top tier.

SCALING DATA REPETITION FOR LLMS

The optimal amount of high-quality domain data repetition increased mildly with model size at a fixed tokens-per-parameter ratio. Smaller proxy models could therefore help estimate repetition schedules for larger models, with lower-loss domains generally tolerating more reuse.

TEACHING EVERYONE TO FISH FOR TOKENS

Open-source AI models face a precarious future due to high capital requirements, with Nvidia heavily investing to drive demand for its chips. The open-source recipe's economic viability is uncertain, potentially leading to a fork focused on efficiency and specialization rather than competing with closed models in lucrative sectors. Meta's strategy to release models like Muse Spark 1.2 as open-weights could disrupt competitors, as they commoditize their complements differently from Nvidia's approach of fostering a self-sustaining token ecosystem.

OWN YOUR INTELLIGENCE: A HOW-TO GUIDE

AI companies should selectively own their intelligence when frontier APIs constrain cost, latency, proprietary data, or strategic control. The roadmap is evals, custom harnesses, targeted post-training, and online learning loops that turn production trajectories into continuously improving domain-specific models.
