In our ongoing exploration of First Drafts' AI Panel System, we are taking a closer look at the individual AI "Justices" that form your cutting-edge legal drafting team. Each model brings a unique set of strengths and a distinct "judicial philosophy" to the table. Today, we shine the spotlight on Holmes: "The Workhorse."

Just as Justice Oliver Wendell Holmes Jr. was renowned for his prolific output, pragmatic wisdom, and enduring influence on American law, our Holmes AI model is engineered to be your steadfast and efficient partner in legal drafting. It's our legacy gold standard, embodying reliability and straightforward professionalism – the trusted engine that gets the essential work done, day in and day out. Holmes is our base model that users have known since our platform's launch in January, 2025.
The Hallucination Index: Understanding Holmes' Citation Accuracy
At First Drafts, transparency is paramount. First Drafts' Hallucination Index is a meta-study on our own models using First Drafts' proprietary standardized testing benchmark of ten fixed test cases ranging in complexity and tasks to determine the citation capability and accuracy of each model. Across four separate classes of citations, each model is scored based on how many of the citations generated from whole cloth is accurate. Hallucination testing is completed by the company's attorney-consultants with access to legal research databases to check citations; the Hallucination Index is an estimation of likely hallucinations that a user might encounter in any given task, and not a guarantee of the model's performance.
The Hallucination Index for Holmes shows it as a balanced performer. It demonstrates solid reliability with higher-level court decisions and foundational legal authorities. While more accurate than some models in its class, especially concerning federal circuit and supreme court cases (pre-October 2024 data), users should exercise standard due diligence, particularly when dealing with citations for lower state courts, federal trial courts, or very specific local rules and statutes. Holmes provides a strong starting point, but as always, attorney review of citations is essential.
The Workhorse in Action: Holmes' Drafting Prowess and Performance
Beyond citations, Holmes is our legacy gold standard for a reason. As "The Workhorse," Holmes excels at producing clear, influential legal text quickly and consistently. It’s not about flashy rhetoric; it’s about getting the core arguments down with dependable precision. If you need a draft that is respectful, measured, and efficiently constructed, Holmes is your go-to. It understands the assignment and delivers without unnecessary complexity, embodying a pragmatic approach to legal writing. Its prose is straightforward, its structure logical – a true workhorse in every sense.
- Fast & Efficient: Holmes prioritizes getting a comprehensive and professional draft into your hands promptly, allowing you to move to the crucial review and refinement stages sooner.
- Clean & Balanced: The prose generated by Holmes is clear, measured, and professional. It strikes a careful balance between creative argumentation and the necessary inclusion of legal knowledge.
- Reliably Grounded: While all AI requires human oversight, Holmes is built on a robust foundation, particularly strong in its understanding and recall of federal circuit court and U.S. Supreme Court cases.
Here's a glimpse into how Holmes performs based on our rigorous internal evaluation framework, where it's compared against other models:
Holmes Model Evaluation Snapshot:
Our evaluation framework reveals Holmes as a true powerhouse of efficiency and reliability:
Holmes achieves an exceptional score in Speed (95), near the top of the charts, underscoring its 'Workhorse' moniker by its capability to rapidly generate drafts. This isn't just raw speed; it's coupled with commendable Overall Effectiveness (84) and Clarity of Writing (84), ensuring that the output is not only quick but also coherent, professional, and immediately useful.
In areas like Legal Reasoning (80) and Thoroughness (80), Holmes demonstrates a strong, focused performance. This reflects its design philosophy: to provide a concision and focus, leveraging solid traditional analysis that gets to the heart of the matter efficiently. Rather than aiming for exhaustive, sprawling detail in initial drafts – a characteristic sometimes found in other models – Holmes prioritizes a well-structured, pragmatic foundation. It's the epitome of getting the essential work done with dependable precision, providing a strong, clear, and rapidly-produced starting point for legal professionals.
Our Inspiration: Justice Oliver Wendell Holmes Jr.
Our Holmes AI is named in honor of Justice Oliver Wendell Holmes Jr., who served nearly 30 years on the U.S. Supreme Court. Known for his efficiency and no-nonsense output, he was a tireless contributor to American jurisprudence. Our Holmes model aims to honor this legacy by providing a highly productive, practical tool for everyday legal drafting. Think of Holmes as the seasoned practitioner who has seen it all. It doesn't always go for the most flamboyant argument, but instead builds a case on solid ground, ensuring that the core tenets are well-articulated and defensible. Its voice is respectful and measured, ideal for a wide range of litigation documents where clarity and dependability are paramount.
As Justice Holmes himself famously stated, "The life of the law has not been logic; it has been experience." Our Holmes model, while driven by sophisticated algorithms, is trained to reflect this pragmatic understanding, delivering drafts that are not just technically sound, but also practically useful. Holmes is more than just our gold-standard AI; it's a dependable partner in your drafting process, designed to provide the essential framework upon which great legal arguments are built.
