AI Analysis

First spotted on Reddit, now with detailed technical analysis, StepFun released Step 3.7 Flash, a 198B-parameter sparse Mixture-of-Experts vision-language model that activates ~11B parameters per token and adds native vision input plus improved tool-use reliability for agentic and search workflows. It targets coding agents while keeping inference compute near an 11B dense model.

StepFun today released Step 3.7 Flash, a multimodal Mixture-of-Experts model targeting agentic use cases. It adds native vision input and improved tool-use reliability over Step 3.5 Flash. What is Step 3.7 Flash? Step 3.7 Flash is a 198B-parameter sparse Mixture-of-Experts (MoE) vision-language model. It pairs a 196B-parameter language backbone with a 1.8B-parameter vision encoder (ViT) for native image understanding. The model activates approximately 11B parameters per token during inf

Hexo Labs Open-Sources SIA: A Self-Improving Agent That Updates Both the Harness and the Model Weights

By Asif Razzaq

60 score

AI Analysis

Hexo Labs open-sourced SIA, a self-improving agent framework under MIT license that updates both the agent's scaffold (prompts, tool logic, retry policy) and the underlying model weights within one improvement loop. A meta-agent writes the initial scaffold while the system iteratively refines both components.

Most AI agents stop improving once a human stops tuning them. The model is fixed. The scaffold around it is fixed. Hexo Labs wants to move both at once. It released SIA (Self-Improving AI) this week as an open-source framework under an MIT license. The core claim of this research is narrow but concrete. SIA edits both the agent’s scaffold and the model’s weights inside one self-improving loop. What is SIA (Self-Improving AI) SIA splits a task-specific agent into two parts.

Meet mKernel: A Multi-GPU, Multi-Node Fused Kernel Library for GPU-Driven Communication

By Asif Razzaq

57 score

AI Analysis

UC Berkeley's UCCL project released mKernel, an open-source library of persistent CUDA kernels that fuse intra-node NVLink communication, inter-node RDMA, and compute into single kernels. It targets the large communication overhead (up to ~47% of execution time in some MoE models) that bottlenecks multi-GPU training and inference.

GPU communication overhead is a measurable bottleneck in production AI workloads. According to data cited by the mKernel project, communication can consume 43.6% of the forward pass and 32% of end-to-end training time. Across popular Mixture-of-Experts (MoE) models, inter-device communication can account for up to 47% of total execution time.

[AINews] Anthropic raises $965B Series H, releases Opus 4.8 and Dynamic Workflows/ultracode

By Unknown

AI Analysis

Anthropic reported a $47 billion revenue run-rate (up from $9B in December) and confirmed a Series H raising $65 billion at a $900 billion pre-money valuation, including hyperscaler and memory-industry backers. The newsletter argues this temporarily puts Anthropic ahead of OpenAI on most headline metrics, alongside the Opus 4.8 and Dynamic Workflows releases.

Anthropic’s path as the fastest growing company of all time has put overtaking OpenAI in its sights for a while, but there were numerous asterisks for the past few months that put the timing (though perhaps not the fact) of the flippening in question. Today Anthropic officially reported $47B in revenue run-rate (reminder, this number was $9B in December!) and confirmed their Series H raising $65B at a $900B pre-money valuation (including $15B from hyperscalers including Amazon, but also th

NVIDIA Introduces X-Token: Projection-Guided Cross-Tokenizer KD That Outperforms GOLD by +3.82 Average Points on Llama-3.2-1B

By Asif Razzaq

55 score

AI Analysis

NVIDIA introduced X-Token, a projection-guided cross-tokenizer knowledge distillation method that lets a small student model learn from teachers with incompatible tokenizers. It reportedly outperforms the GOLD baseline by 3.82 average points on Llama-3.2-1B, enabling cross-family and multi-teacher distillation.

Knowledge distillation (KD) transfers “dark knowledge” from a large teacher model to a smaller student. The student learns from the teacher’s full output probability distribution over tokens, not just correct answers. This is done via per-position Kullback–Leibler (KL) divergence over next-token probability distributions. This formulation requires a shared tokenizer. A practitioner committed to Llama-3.2-1B cannot leverage stronger teachers with incompatible tokenizers — suc
