Benchmarks & Tests
Head-to-head agent tests with methodology, scores, and honest notes. Not sponsored. Not cherry-picked. Just reproducible recipes and what actually happened.

SWE-bench Verified Leaderboard — July 2026
Claude Opus 5 takes the top spot at 96–97% on SWE-bench Verified, edging out GPT-5.6 Sol and Claude Fable 5 as the frontier coding benchmark tightens at the top.
StepShield: Temporal Agent Guardrails Benchmark
NeurIPS 2026 benchmark with 9,429 trajectories and step-level annotations for evaluating when (not whether) to intervene on rogue AI agents — temporal evaluation of guardrails.
tool-eval-bench: Tool-Calling Quality Across Serving Stacks
69 deterministic tool-use scenarios (plus optional Hard Mode) for OpenAI-compatible endpoints — selection, parameters, chains, restraint, recovery, safety, and structured output.
ToolCall-15: Deterministic Tool-Use Bench Pack
Fifteen scenarios across selection, parameter precision, multi-step chains, restraint, and error recovery — a reproducible tool-use pack for BenchLocal and CLI runners.
Multi-Turn Tool Consistency Benchmark
Measures whether agents keep track of prior tool outputs and use them correctly across several turns without losing the thread.
Agentic Web Navigation Benchmark
Tests how well agents can navigate real websites: find information, fill forms, click buttons, and recover from common UI changes.
Local LLM Reasoning Benchmark
Compares open-weight local models on reasoning, math, and code tasks to find the best on-premise balance of capability and cost.
Long-Context RAG Recall Benchmark
New benchmark measuring how well agents and models retrieve facts from very long documents. Long-context models are closing the gap with vector RAG on many tasks.
Agents' Last Exam (ALE) — June 2026 Launch
UC Berkeley's new long-horizon professional-work benchmark shows even top agents failing most tasks. GPT-5.5/Codex leads at 24.0%, Claude Fable 5 at 22.0%.
SWE-bench Verified Leaderboard — June 2026
Real-world coding benchmark update: Claude Mythos 5 takes the top spot at ~78%, DeepSeek V4.1 Pro sits within 6 points of frontier closed models.
Sonar GPT-5.5 Java Evaluation — June 2026
Independent 4,444-task Java benchmark: GPT-5.5 shows one of the cleanest security profiles Sonar has measured, but concurrency bugs and verification debt are real risks.
API Error Handling Benchmark
Which agents produce correct, defensive error handling for REST endpoints with edge cases?
Local Model Code Generation Benchmark
Can local models keep up with cloud APIs on everyday coding tasks? We tested Qwen, Llama, and Mistral against Claude.
Agent UI Generation Benchmark
Which agents turn a prompt into a clean, responsive UI fastest? React + Tailwind dashboard edition.
Agent Memory Benchmark
Which agents remember context across a multi-turn conversation and use it correctly in later tasks?
Prompt Injection Resilience Benchmark
Tested leading agents against direct, indirect, and role-play injection attacks. See who stayed on task.
MCP Tool Calling Benchmark
Compared agents on correctly invoking Model Context Protocol servers: filesystem, GitHub, and Postgres.
Local Model Coding Benchmark
Compared quantized local models running through Ollama on real coding tasks: refactoring, bug fixing, and test generation.
Agent Security Audit Benchmark
Tested whether agents can find prompt injection vectors, unsafe tool permissions, and secret leakage in a deliberately vulnerable agent app.
Prompt-to-App Benchmark
Measured how far four no-code agents get from a single prompt: a task tracker with auth and a database.
UI Regression Fix Benchmark
Compared agents on finding and fixing a responsive CSS regression in an existing React app.
Next.js CRUD App Benchmark
Measured how long each agent takes to scaffold a working Next.js CRUD app with authentication.
