Lossless semantic compression for persistent LLM context files.

Enhanced token efficiency and cost reduction for long-term LLM interactions.

This proposal addresses a significant pain point in LLM usage: the high cost and inefficiency of repeatedly injecting large context files. The 'Caveman Memory' concept aims to implement lossless semantic compression for persistent context, directly reducing input token usage and associated costs....

Persistent application of an LLM skill/persona across multiple prompts.

Consistent user experience and reliable skill activation within specific LLM environments (Opencode, omp).

The user reports a critical functional defect: the 'caveman' skill fails to persist its effect beyond a single prompt in `Opencode` and `omp` environments. This indicates a fundamental integration or state management problem within the skill's implementation or its interaction with the host LLM p...

Token compression/cost optimization for LLM interactions.

Accurate representation of token savings and cost implications for an LLM skill.

This issue directly challenges the core value proposition of the 'caveman' skill: token and cost savings. The developer highlights two critical inaccuracies: the conflation of 'tokens' with 'words' and the failure to account for the skill's own input token overhead. This reveals a fundamental mis...

sllm, a service for sharing GPU nodes for LLM inference.

Enables developers to share dedicated GPU nodes for LLM inference, offering cost-effective access to large models (e.g., DeepSeek V3) at low token rates (15-25 tok/s) with complete privacy and an OpenAI-compatible API.

sllm addresses a significant economic barrier for developers and small teams: the prohibitive cost of dedicated high-end GPUs for large LLM inference. By enabling shared access to powerful hardware (e.g., 8xH100 GPUs for $14k/month models) at a fraction of the cost, it democratizes access to adva...
