Caveman Plugin Hits 34K Stars by Making Claude Talk Like a Caveman
The Caveman plugin for Claude Code cuts 65-87% of output tokens by stripping filler words and using terse fragment-based language. Its new Classical Chinese mode pushes compression even further.
A $900 RTX 3090 Now Beats an M5 Max at LLM Inference
Two researchers fused all 24 layers of Qwen 3.5-0.8B into a single CUDA kernel launch, making a five-year-old RTX 3090 deliver 1.8x the throughput of an M5 Max at equal or better efficiency. The gap was software, not silicon.
Compact Contexts, Smarter Fine-Tuning, and the Solver Trap
Three papers from today's arXiv: a joint fix for KV cache bloat and attention cost, new evidence that fine-tuning belongs in the middle of a transformer, and why stronger reasoning hurts behavioral simulation.
NVIDIA Groq 3 LPU - SRAM-Based Inference Engine
The NVIDIA Groq 3 LPU is a pure-SRAM inference chip delivering 150 TB/s memory bandwidth and 1.2 PFLOPS FP8 per chip, designed to pair with Vera Rubin GPUs for trillion-parameter model serving.
Positron Atlas - FPGA Inference Server
The Positron Atlas is an 8-card FPGA inference server delivering 4.5x better performance per watt than the NVIDIA DGX H200 at 2000W in a single 1U chassis.
MoE Myths, Context Compression, and Steering Proofs
Three papers this week challenge how we think about MoE expert routing, LLM context management, and the limits of activation steering.
OpenRouter Drops a Free 100B Stealth Model With 256K Context
Elephant Alpha is a free 100B parameter model on OpenRouter with 256K context, tool use, and structured output - but your prompts get logged, there are no benchmarks, and nobody knows who made it.
Intel Arc Pro B70 Brings 32GB VRAM to Local AI for $949
Intel's Arc Pro B70 launched on March 25 with 32GB GDDR6 and 367 TOPS for $949, undercutting NVIDIA's RTX Pro 4000 by $850. The hardware case is strong. The software story is not.
AMD Instinct MI325X - 256GB CDNA3 for Inference
AMD Instinct MI325X specs, benchmarks, and analysis. 256GB HBM3e at 6 TB/s, 2.6 PFLOPS FP8, CDNA3 architecture - the memory-capacity upgrade to the MI300X targeting large model inference.
Huawei Atlas 350 - China's FP4 Inference Accelerator
Huawei Atlas 350 specs, benchmarks, and analysis. Ascend 950PR chip, 112GB HiBL 1.0 HBM, 1.56 PFLOPS FP4, 600W - China's first domestically developed FP4-capable AI accelerator.
Microsoft Maia 200 - Azure's Inference Accelerator
Microsoft Maia 200 specs, benchmarks, and architecture analysis. TSMC 3nm, 216GB HBM3e, 10 PFLOPS FP4, 750W - Microsoft's first inference-only silicon deployed in Azure.
