AI research

Understanding AI, in fine detail.

Femtosol is an AI research company. We study how intelligent systems learn, reason and fail — and work to make that understanding useful.

Research

What we work on

Our research spans the questions that matter most for building AI systems people can understand, measure and trust.

  • 01

    Learning & generalization

    How models acquire knowledge and skills from data, why they generalize, and where that breaks down.

  • 02

    Reasoning & agents

    Systems that plan, use tools and act reliably over long horizons — and how to tell when they are actually reasoning.

  • 03

    Interpretability

    Opening up trained models to understand the mechanisms behind their behavior, not just the outputs.

  • 04

    Safety & robustness

    Failure modes, reliability under distribution shift, and behavior under adversarial pressure.

  • 05

    Evaluation

    Measurement that tracks real capabilities, with benchmarks and methods that hold up to scrutiny.

  • 06

    Efficient AI

    Capable models that need less compute, data and energy to train and run.

Work

What we build

Beyond research, we build the tooling that makes AI systems observable, testable and understandable. The interfaces below are illustrative examples of these kinds of systems.

Illustrative monitoring dashboard: latency, error rate and drift tiles above a line chart of output drift that crosses an alert threshold.

Monitoring

AI monitoring systems

Live visibility into model behavior in production — latency, error rates and output drift — with alerts before users notice.

Illustrative QA dashboard: a donut showing a 94 percent overall pass rate beside per-suite progress bars for factuality, refusals, tool use, long context and regression.

Quality assurance

AI QA dashboard

Automated test suites for model quality, rolled up into pass rates and regressions so teams can release with confidence.

Illustrative benchmark chart: grouped bars comparing a baseline and two model versions on reasoning, coding, retrieval and safety tasks.

Evaluation

Benchmarking & evaluation harnesses

Reproducible harnesses that compare models and versions side by side on the tasks that matter.

Illustrative interpretability tool: an attention heatmap over eight tokens where the word it attends strongly to cat, with a side panel of feature scores.

Interpretability

Model inspection tools

Visual tools for examining attention and internal features, to see why a model produced a given output.

Illustrative robustness report: circles sized by attack success rate for five attack categories across three model versions, shrinking from v1 to v3.

Safety

Red-teaming & robustness reports

Systematic adversarial testing that tracks how attack success rates change from one model version to the next.

Illustrative agent trace viewer: a timeline of six steps including a failed code execution followed by a successful retry, verification and a final answer.

Agents

Agent trace analysis

Step-by-step timelines of agent runs — tool calls, retries and failures — for debugging and evaluation.

Approach

How we do research

Careful with claims

We say what the evidence supports and no more, and we are explicit about what we do not yet know.

Grounded in experiments

Ideas earn their place through controlled, reproducible experiments rather than intuition or trend.

Built to be useful

We aim for findings that other researchers and practitioners can build on and put to work.

About

A small name for a big question

Femtosol is an AI research company. We are interested in the details: the mechanisms inside models, the edge cases in evaluations, and the small differences that decide whether a system works.

We believe progress in AI depends on understanding it more deeply, and we organize our work around that goal.
