Cartridges is an open-source single-GPU PyTorch reproduction of two recent papers on KV-cache compaction for long-context LLM inference: "Cartridges" (lightweight long-context representations via self-study condensation) and "STILL." Both methods address the same bottleneck — KV caches grow linearly with context length and quickly become the dominant memory consumer in long-context inference, making extended context windows impractical on consumer hardware. The Cartridges paper proposes condensing long contexts into compact "cartridge" representations through a self-study phase, trading some context fidelity for dramatic memory reduction. STILL uses a different approach focused on selective layer-wise compression. This repository makes both reproducible on a single consumer GPU — previously these required multi-GPU setups accessible mainly to research labs. KV-cache memory is one of the primary bottlenecks preventing long-context models from running efficiently on local hardware. A working single-GPU reproduction of these techniques is directly useful to anyone building long-context applications outside of cloud environments, and may accelerate community development of hybrid compaction strategies not in the original papers.

Scientific Agent Skills is an open-source toolkit of 134 ready-to-use scientific domain skills for AI agents, covering cancer genomics, drug-target binding prediction, molecular dynamics, RNA velocity analysis, geospatial science, and time series forecasting. Each skill integrates with 78+ scientific databases and is backed by 70+ optimized Python packages, installable with a single npx command into agents like Claude Code, Cursor, or Codex. The core idea is separating scientific compute from the agent's reasoning loop. Instead of asking an LLM to hallucinate bioinformatics pipelines, you give it callable skills that actually connect to NCBI, PDB, ChEMBL, and other authoritative data sources. Optional cloud compute via Modal handles GPU-intensive workloads — molecular dynamics simulations, protein structure inference — without requiring local hardware. Forty-plus model integrations mean the skills layer is agent-agnostic. With 18.1k GitHub stars, this project is filling an obvious gap: the agent ecosystem has exploded in developer tools but scientific workflows have lagged behind. A bioinformatician can now wire up a Claude Code agent that genuinely queries gene expression databases, runs differential analysis, and interprets results — without writing custom integration code for each data source.
Reviewer scorecard
“KV-cache memory is the wall that stops long-context models from running locally. A clean single-GPU reproduction of two compaction approaches in one repo is exactly what the community needs to evaluate tradeoffs without re-implementing from scratch. The self-study condensation approach in Cartridges could be a game-changer for local inference.”
“The npx install pattern means I can wire 78 scientific databases into my agent in minutes. The Modal integration for GPU workloads is a thoughtful design decision — it keeps the local agent lightweight while offloading the heavy compute. This is exactly the kind of batteries-included toolkit the scientific computing community needs.”
“Two stars on GitHub and posted within hours — this is as early as it gets. Reproducing research papers is notoriously error-prone and the author hasn't had time to validate results against original paper benchmarks. Worth watching, but don't build production systems on it until the community has stress-tested the implementation.”
“Database integrations go stale fast — API endpoints change, authentication requirements shift, data formats get versioned. A 134-skill library is a massive maintenance burden for what appears to be a small team. Check the issue tracker before depending on this for anything publication-critical.”
“The open-source community making frontier inference techniques accessible is what drives capability proliferation. Every time a technique goes from 'paper + multi-GPU cluster' to 'laptop + single GPU,' the addressable user base for long-context applications expands by orders of magnitude. Cartridges points directly at that transition.”
“This is accelerating AI-assisted drug discovery and genomics research by months. When an AI agent can natively call ChEMBL binding affinity data and run molecular docking simulations as skills, we've collapsed the distance between research hypothesis and computational validation. The implications for rare disease research are enormous.”
“Honestly too deep in the research weeds for most content creators unless you're specifically building local long-context pipelines. This is a tool for ML engineers and researchers first. If the techniques prove out, the benefits will eventually arrive via model updates rather than DIY implementation.”
“For science communicators and data journalists, this is a game-changer. Instead of waiting for a bioinformatician to run an analysis, you can point an agent at the skill library and get interactive cancer genomics visualizations yourself. The barrier to data-driven science storytelling just dropped significantly.”
