Arcee Trinity-Large-Thinking is a 400B sparse MoE open-source reasoning model that ranks #2 on PinchBench at $0.85/M output tokens, 28x cheaper than Claude Opus 4.6.

Alibaba's 35B sparse MoE with 3B active parameters delivers 73.4% SWE-bench Verified, multimodal vision and video, 256K context, and DeltaNet hybrid architecture under Apache 2.0.

Alibaba's Qwen 3.6-35B-A3B activates only 3B of its 35B parameters per token, scores 73.4% on SWE-bench Verified, handles video and images, and ships under Apache 2.0.

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.

Cal.com moved its core codebase to a private repo after five years of open source, arguing AI tools make public code 5-10x easier to exploit. The community isn't buying it.

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.

A hands-on comparison of the top AI unit test generation tools in 2026, covering Qodo Gen, GitHub Copilot, Diffblue Cover, Keploy, and Tusk.

HappyHorse-1.0 topped the Artificial Analysis Video Arena with a 52-Elo gap over Seedance 2.0 - but the 'open source' model has no public weights, no inference code, and no API.

UC Santa Barbara researchers found 9 of 428 third-party LLM routers actively injecting malicious tool calls, draining crypto, and stealing AWS credentials from AI agent sessions.

NVIDIA releases two open-source AI models for quantum hardware - a 35B vision-language model that cuts calibration time from days to hours, and CNN decoders that outpace the standard by 2.5x.

Linux 7.0 ships an official AI code policy: disclose AI tool usage with an Assisted-by tag, keep humans on the hook for every line, and stop submitting slop.
