GuppyLM is a deliberately tiny language model — 9 million parameters, 6 transformer layers — that roleplays as a fish and can be fully trained in under 5 minutes on a free Google Colab T4 GPU. The entire pipeline from data generation to training loop to inference fits in approximately 130 lines of PyTorch, making it the most compressed end-to-end LLM tutorial available. Unlike educational projects that paper over complexity with abstraction layers, GuppyLM deliberately avoids modern optimizations — no RoPE positional encoding, no grouped-query attention, no SwiGLU activations. You see exactly why each component exists when you remove it. It ships with a 60,000-example synthetic conversation dataset and produces coherent (if goofy) fish-themed responses after training. The project hit the top of Hacker News Show HN with 365 points and 31 comments. Developers praised how the simplicity forces you to confront how training data shapes model behavior directly, with multiple commenters saying it's the clearest path from 'I know Python' to 'I understand why LLMs work.'

WUPHF
Open-source multi-agent 'office' — AI teams that think together

WUPHF is an open-source orchestration system that turns multiple LLM agents into a visible, collaborative 'office.' Spawn a CEO, PM, engineers, and designers as agents running simultaneously — all able to @mention each other, claim tasks, and maintain a shared wiki of knowledge. It's like GitHub for agent thought. The architecture is cleverly frugal: instead of accumulating context, WUPHF uses fresh sessions per turn with Claude's prompt caching, hitting 97% cache hit rates and dropping five-turn sessions to roughly $0.06. Agents are push-driven — they only wake when notified, meaning zero idle token burn. A dual memory system (per-agent Notebooks + shared Wiki) keeps the team aligned across sessions. Built by indie developers and spotted trending on Hacker News, WUPHF targets the rapidly growing segment of builders who want more than one AI "employee" but don't want to pay enterprise orchestration prices. Telegram bridge, Composio integration, and a clean web UI at localhost:7891 round out the package.
Reviewer scorecard
“130 lines from raw data to inference — I've never seen a more honest on-ramp to transformer internals. The deliberate omission of RoPE and SwiGLU forces you to understand the delta between vanilla and modern architectures. Assign this to every junior ML engineer before they touch Hugging Face.”
“The token-efficiency story alone makes this worth trying — $0.06 for a five-agent session is remarkable. The @mention graph and shared wiki are genuinely novel patterns that every multi-agent framework should steal.”
“This is education, not tooling — calling it a 'language model' is generous for something that outputs fish puns. The synthetic training data is simplistic and the architecture is years behind real LLMs. Fine for learning, but don't confuse novelty with utility.”
“The 'AI office' metaphor sounds fun until you're debugging why the agent-CEO contradicted the agent-PM three turns ago. Fresh-session architecture fixes cost but breaks longitudinal reasoning — agents can't truly learn from mistakes across days.”
“The best thing about GuppyLM is that it normalizes building your own models from scratch. As AI democratizes, the next generation of builders needs to understand transformers at the implementation level — not just prompt them. This is exactly the kind of artifact that spawns a thousand domain-specific tiny models.”
“This is what agent-native software development looks like before the big platforms catch up. The Telegram bridge and push-driven activation pattern hint at a world where your 'team' lives in your chat app, not a browser tab.”
“A fish that learned to talk about water from 60K synthetic conversations is unexpectedly charming. The project has a clear personality and a memorable hook — it's the kind of thing that goes viral in classrooms because students actually want to run it. Clever branding for an educational tool.”
“Being able to spin up a dedicated 'creative director' agent alongside your developer agents is genuinely useful. The visible activity stream means you can actually see the creative process unfolding in real-time.”
