l6e – An MCP server for AI agent budgeting

An MCP server that enables AI agents to operate within a defined budget, directly addressing the problem of uncontrolled token spending and context window bloat in tools like Cursor + Opus, leading to cost savings and "smarter" (more resource-aware) agent behavior.

l6e addresses a critical, unmanaged cost center in AI agent development: uncontrolled token consumption. By implementing a budgeting mechanism via an MCP server, it provides enterprises with direct control over AI spending, preventing unexpected cost escalations from "token-hungry" models and sub...

An experiment demonstrating AI model degradation based on financial constraints

A conceptual demonstration, inspired by ALMA, illustrating how an AI agent (Claude) degrades in decision-making capability as its financial resources diminish, forcing it to use less capable models (Opus → Sonnet → Haiku).

This is a conceptual experiment, not a B2B SaaS product. It highlights a critical economic reality for AI deployments: the direct correlation between model cost and performance. The "gambling" metaphor effectively illustrates how resource constraints force a trade-off in AI quality, leading to su...

Flint – A 30B LLM fine-tuned for increased output diversity

A fine-tuned Qwen3 30B model specifically engineered to address the lack of output diversity in frontier LLMs for open-ended queries, demonstrating that "divergence tuning" can significantly increase novelty without compromising performance on non-creative tasks.

Flint addresses a critical limitation of current frontier LLMs: their tendency towards repetitive or low-diversity outputs, especially for creative or open-ended tasks. By demonstrating that a 30B model can be fine-tuned for significantly higher entropy and novelty without sacrificing core capabi...
