Baidu released the FP8 and BF16 weights for ERNIE 5.5 Flash Base on Hugging Face and ModelScope under ERNIE 5.5 Flash Base License v1.0

The ERNIE 5.5 Flash Base License v1.0 is free for entities with under US$50 million in revenue but explicitly excludes usage in the European Union, United Kingdom, and South Korea

The Mistral Ecosystem Open-Weight License for Mistral Large 4 contains no revenue threshold and explicitly exempts internal enterprise use and end-user products with embedded model features from separate licensing requirements

Mistral released Mistral Large 4 under the Mistral Ecosystem Open-Weight License, a modified MIT license requiring a separate commercial agreement for entities operating model-as-a-service businesses

Liquid AI released LFM3 under the LFM Open License v1.0, requiring commercial organizations generating over $10 million in annual revenue to obtain a separate commercial agreement

Liquid AI's LFM3 post-training pipeline comprised four stages: supervised fine-tuning on 1.75 trillion tokens, mixed reinforcement learning, distillation of six specialist teachers into one model, and agentic reinforcement learning

Carbon-X releases its model weights under an Apache 2.0 license, permitting biological research laboratories to run the model locally on 1 x 80 GB GPUs

DeepSeek published the open-weight model files for DeepSeek-V4.1-Flash-1017 on Hugging Face and ModelScope on October 17, 2026

Black Forest Labs released FLUX 3 Image Klein in a base version, a lower-latency distilled version, and compressed FP8, NVFP4, and INT8 versions

The FLUX Kommunity License grants free commercial use of FLUX 3 Image Klein under $5 million annual revenue; organizations over $5 million require a separate commercial self-hosting arrangement or hosted API

The FLUX Kommunity License for FLUX 3 Action determines eligibility using gross annualized revenue combined across affiliates rather than individual project budgets

Muse Spark Open is available free to download under a commercial license requiring the label 'Built with Muse Spark Open,' while API providers earning over $20 million annually require a separate agreement

Nvidia released base, post-trained, and compressed weights for Nemotron 3.5 Super VL under the OpenMDW license, alongside training recipes and 25 trillion tokens of pretraining data

Model distillation allows competing companies to reproduce advanced AI capabilities faster and at lower cost by copying an existing model's output and reasoning steps

Anthropic identified Chinese AI company Moonshot as a participant in distillation campaigns that secretly routed queries through Claude AI models

Anthropic banned tens of thousands of accounts linked to distillation campaigns attempting to extract capabilities from Claude AI models

Anthropic implemented new safeguards restricting access to Claude's reasoning that reduced reasoning tokens extracted from Claude AI models by 90% to 99%, or 10 to 100 times lower than previous levels

Anthropic called on rival AI developers to adopt defensive protections against model distillation attacks

Anthropic made it harder to use proxy networks to probe Claude AI models by restricting access to internal reasoning steps, running an extraction detection classifier, and blocking automated queries

Leading US AI developers including Anthropic, OpenAI, and Google face increasing model distillation attempts driven by intensifying US-China technology competition
