Lecture pages and resources covering prompt engineering, augmented language models, LLMOps, and language UI/UX.
Multi-year course content on infrastructure, data management, deployment, monitoring, and ML team organization.
Current material on collaborating with and building agent-based systems, including a perspective on multiplayer AI.
A maintained guide to cloud GPU options that helps teams choose compute for training and inference.

Alibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.
Covers every compute envelope from the multi-trillion-scale Qwen4-Max flagship and Qwen4-Plus/Flash APIs to the local PC-friendly Qwen4-27B open-weight checkpoint, plus qwen4-coder-plus and qwen4-omni-120b-think.
Pioneered in the Qwen3.8-Flash-Next architecture preview, combining ultra-lean active parameter routing (6B active out of 125B) with a 51B n-gram embedding layer that trades compute for instant memorized lookup.
Sizes the Qwen 4 generation at a full 1M-token context window across text, code, images, audio, and video for repository-wide coding and cross-document reasoning.
Trained via multi-cycle automated Recursive Self-Improvement across coding, math, and hardware EDA workflows—demonstrating 10,000+ autonomous tool calls in chip design and software engineering.
Free / Open-sourceProvides state-of-the-art open-weight reasoning models and low-cost APIs, but with less emphasis on multimodal Alibaba ecosystem tools.


Provides robust developer tools and multimodal APIs, but relies on Google's closed Gemini models rather than open-weight alternatives.
#2SpecialistAggregates hundreds of models behind one API gateway, but functions as a router rather than hosting native Qwen infrastructure.
#3
Offers competing Chinese foundation model APIs and agent builders, but specializes in Zhipu AI's GLM architecture.

Free / Open-sourceProvides lightweight open-weight models for local deployment, but offers smaller parameter sizes compared to top-tier Qwen variants.


SpecialistDelivers ultra-fast inference speeds using custom LPU hardware, but supports a more limited selection of open models.
