AI Model Benchmarks & Protocol Scorecards
Data-driven evaluation of frontier LLMs, Model Context Protocol (MCP) transports, and in-band security overhead. We publish empirical measurements of latency, tool schema accuracy, and token unit costs to guide enterprise infrastructure decisions.
Neon Innovation Lab AI Benchmarks is an empirical performance registry that evaluates Large Language Models (Claude 3.5 Sonnet, GPT-4o, Gemini 1.5 Pro, Llama 3.3) across tool-call precision, Time-to-First-Token (TTFT), and token costs. In addition, we benchmark Model Context Protocol (MCP) transport overhead, verifying that our Zero-Trust Gateway operates with sub-1.2ms latency.

Frequently Addressed Questions
Concrete answers covering architecture, integration protocols, security, and SLAs.
How frequently are Neon Innovation Lab AI benchmarks updated?+
We continuously evaluate models as new frontier checkpoints and open-weights releases become available. Our automated evaluation harness runs weekly regression suites across Claude, OpenAI, Google Gemini, and Meta Llama models.
Why is tool-call schema accuracy more critical than raw benchmark scores (like MMLU)?+
In autonomous agent and MCP workflows, an AI model that fails to format arguments to exact JSON schema specifications causes runtime exceptions and halts the entire engineering pipeline. High schema accuracy ensures dependable, deterministic execution without human troubleshooting.
How do you measure in-band DLP inspection overhead?+
We benchmark our Zero-Trust Gateway using high-frequency Node.js micro-benchmarks with hrtime (nanosecond precision) across thousands of concurrent tool input and output payloads containing realistic PII, API tokens, and SQL queries. Our average overhead consistently measures under 1.2 milliseconds.
Can our organization benchmark our internal fine-tuned models using your harness?+
Yes. Our testing suite can be pointed at any OpenAI-compatible or vLLM private endpoint to evaluate internal models against standard tool-call fidelity and latency metrics.
