Why Lex
Most Agents are built for everything.
Lex is built for law.
Generic AI tools confuse visitors, give bad advice, and capture nothing useful. Lex was designed ground-up for legal intake — with structured qualification flows, safe response guardrails, and direct delivery to your team. The result is a faster, cleaner pipeline with less effort from you.

AI Intelligence
The model powering Lex
outperforms every competitor.
Lex is benchmarked head-to-head against GPT-4o, Claude Opus 4, DeepSeek V3, and Kimi K2 across reasoning, knowledge, coding, and factual recall.
AIME 2025
Advanced math olympiad — the hardest public reasoning benchmark. Lex scores nearly 3× GPT-4o.
GPQA Diamond
PhD-level science questions in biology, chemistry, and physics. Lex beats GPT-4o by 10.6 points.
Capability Radar
Lex holds the largest footprint across all five dimensions simultaneously.
* Long Context score is a normalized composite from public recall benchmarks.
Power vs. Efficiency
Lex sits top-right — elite reasoning with best-in-class cost efficiency. No other model comes close on both axes.
Bubble size reflects relative model scale. Efficiency score is a composite of API cost per token and throughput.
Bottom line: Lex's underlying model leads on AIME reasoning (70.3), factual recall (84.3 CSimpleQA), and GPQA expert knowledge (77.5) — while remaining significantly more cost-efficient than GPT-4o or Claude Opus 4. That means faster, smarter intake conversations and a lower cost per qualified lead for your firm.
