AEVS
Fetch.ai
Free
Open-source SDK that creates tamper-evident, cryptographically signed receipts for every tool call an AI agent makes.
Key features
Signed Receipts: Records every tool call and seals it with an ECDSA P-256 signature backed by KMS.
Hash-Chained Logs: Links each receipt to the previous one so tampering or skipped steps are detectable.
Independent Verification: Confirms signatures via a public API or explorer using only a reference ID.
Drop-In SDK: Installs with pip and wraps existing tools without changing them.
Framework Auto-Detection: Automatically integrates with LangChain and MCP-based agents.
Open Source: Released as fetchai/AEVS-sdk for Python 3.10–3.13.
Best for
Agent Auditing: Keep a verifiable record of exactly what an agent did and when.
High-Stakes Actions: Prove execution of sensitive operations such as payments or refunds.
Compliance Evidence: Provide tamper-evident logs for regulated or accountable workflows.
Debugging Agents: Inspect tool inputs, outputs, timing, and errors for each call.
Third-Party Verification: Let external parties confirm an action occurred without sharing source code.
Gaia2 is an open benchmark and evaluation suite of 800 dynamic scenarios for studying and comparing generalist agent capabilities.
Key features
Large-scale Dynamic Scenarios: A packaged corpus of 800 curated scenarios across multiple universes that exercise long-horizon, multi-step tasks requiring tool use, reasoning, and multimodal inputs.
Capability Configurations: Supports targeted evaluations across capabilities such as execution, search, adaptability, time-awareness, and ambiguity handling to isolate strengths and weaknesses of agents.
Multi-Phase Evaluation Pipeline: Executes three evaluation phases — standard, Agent2Agent, and noise — enabling comparisons under clean, interactive, and perturbed conditions.
Variance and Robustness Analysis: Enforces multiple runs (e.g., 3 runs per scenario) and aggregated metrics to measure variance, stability, and robustness of agent behavior.
ARE CLI/SDK Integration: Native integration with the ARE toolkit (are-run, are-benchmark gaia2-run) for local testing, batch evaluation, and reproducible experiment orchestration.
Leaderboard-Ready Trace Generation: Produces submission-ready trace artifacts and automated evaluation hooks for uploading to the Hugging Face GAIA leaderboard.
Model Provider Flexibility: Works with multiple model backends (via LiteLLM and other integrations) so researchers can plug diverse LLMs and tool stacks into the evaluation pipeline.
Gated-but-Accessible Dataset Governance: Publicly hosted on Hugging Face with controlled access agreement to avoid data contamination and ensure fair benchmark usage.
Comprehensive benchmark of 800 dynamic scenarios spanning 10 universes
ARE CLI tooling: are-run, are-benchmark, and gaia2-run commands for scenario execution and evaluation
Three evaluation phases: standard, Agent2Agent, and noise, with 3 runs per scenario for variance analysis
Integration with Hugging Face Hub: dataset hosting, Hugging Face Spaces demo, and leaderboard submission
Submission-ready trace generation with oracle events and ground-truth for automated evaluation
Configurable capability splits (e.g., execution, search, adaptability, time, ambiguity) and dataset splits (validation)
Supports multiple model providers via LiteLLM integration and Hugging Face model ecosystem
Scenario browser UI in ARE environment and ability to load Gaia2 directly from the Hugging Face Datasets tab
Requires Hugging Face authentication (huggingface-cli login) to access dataset and submit results
Open-source reference implementations, demos, and documentation (blog post, paper, GitHub ARE repo)
Best for
Benchmarking Generalist Agents: Compare LLM-based agent systems on long-horizon, tool-using tasks to measure execution, search, and adaptability capabilities against a community leaderboard.
Researching Robustness and Variance: Run repeated scenario trials with noise and Agent2Agent phases to study stability, failure modes, and sensitivity to perturbations in agent policies.
Tool and Pipeline Validation: Validate integrations between LLMs and external tools (code execution, web search, file handling) by executing Gaia2 scenarios that require real tool calls.
Agent Architecture Comparison: Evaluate different agent designs (planner-actor, chain-of-thought, tool-routing) on identical scenario sets to quantify architectural trade-offs.
Coursework and Benchmarks for Education: Use Gaia2 in practical assignments and projects (e.g., Hugging Face agents course) to teach agents engineering and evaluation best practices.
Leaderboard-driven Iteration: Continuously improve and submit agent traces to the Hugging Face GAIA leaderboard to track progress and compare against community baselines.
Agent-Agent Interaction Studies: Use the Agent2Agent evaluation phase to study emergent behaviors, cooperation, or adversarial interactions between autonomous agents.
