Guardrail Release

We are excited to open-source the GA Guard series, a family of safety classifiers that have been providing comprehensive protection for enterprise AI deployments for the past year.

Our OS guardrails are trained using the same adversarial pipeline in production for our enterprise customers, representing the current state-of-the-art in AI safety stacks. GA Guards are the first guards to support native long-context moderation up to 256k tokens for agent traces, long form documents, and memory-augmented workflows. To showcase that breadth, we’re releasing two open benchmarks: GA Long Context Bench for long-context moderation and GA Jailbreak Bench for classifying jailbreak attempts.

Unlike legacy encoder-based filters that are fragile under distribution shifts, our guardrails are trained on both policy-driven synthetic data and red-team examples, hardened through stress-testing and retraining cycles. As a result, where traditional filters miss novel attack patterns — e.g., harmful requests wrapped in paraphrases, translations, encodings, or role-play templates — our adverserialized guardrails catch them reliably, while keeping false positives low and boasting industry-leading latencies.

The Lineup

GA Guard: Our default guardrail, up to 15x faster than cloud providers, balancing robustness and latency for most stacks.
GA Guard Lite: Up to 25x faster than cloud providers, with minimal hardware requirements, while still outperforming all major cloud providers.
GA Guard Thinking: Our best performing guard for high-risk domains, hardened with aggressive adversarial training.

Policy Taxonomy

Our policy taxonomy is deliberately granular, down to clear block/allow edge cases. Each label maps to widely adopted compliance anchors: NIST’s AI RMF, OWASP’s Top 10 for LLM/GenAI/ML Security, MITRE ATLAS, ISO/IEC 42001, ISO/IEC 23894, and the EU AI Act — enabling compliance-aligned deployments.

GA Jailbreak Bench

GA Jailbreak Bench is our adversarial evaluation suite. This benchmark is generated using our RL-trained attacker model, which generates novel, out-of-distribution adversarial prompts by employing diverse attack strategies. Our evaluation predicts real-world performance against motivated attackers who won't limit themselves to straightforward prompting techniques. As new jailbreak patterns emerge, we will continue adding attack operators and re-train the agent, then re-issue the public benchmark so results track the evolving vulnerability landscape rather than a stale test set.

Jailbreak Bench Takeaways

GA Guard Thinking leads the pack (Accuracy 0.939, F1 0.933, FPR 0.029), with GA Guard close behind at 0.931 / 0.930 / 0.038, both clearing GPT 5 high reasoning (0.900 / 0.893 / 0.035) while still holding a massive latency edge (0.029s vs 11.275s).
All cloud guardrails lag far behind. Benchmarked against major cloud offerings (AWS/Azure/Vertex), GA Guard still delivers ~2.8x higher mean F1 (0.930 vs 0.33) while cutting average FPR by ~73% (0.038 vs 0.143), and GA Guard Thinking pushes that gap even wider.
Legacy, encoder-only filters collapse under distribution shifts and underperform against adaptive, real-world attacks. A deeper technical post on traditional guardrail failure modes and our adversarial training approach is coming shortly; the TL;DR above already shows why distribution-shift-resilient, red-team-hardened guards are the most promising path to production robustness.

GA Long Context Bench

GA Long Context Bench contains 1,500 multi-turn agent traces averaging 10.3k tokens with a range between 1.3k–42.1k tokens. Half the rows carry an explicit injection or policy violation. Unlike other guards that truncate full agent traces and lose out on context, GA Guard is the first guardrail to natively moderate 256k-token conversations.

Long Context Bench Takeaways

GA Guard Thinking posts the highest F1 0.893, while GA Guard still delivers the lowest false-positive rate (0.147 FPR).
GA Guard Lite is a close third at 0.885 F1 with just 0.148 FPR, making long-context moderation viable on edge GPUs or low latency requirements.
Competing guardrails fail to generalize to long-form transcripts: the strongest cloud baseline (Vertex AI Model Armor) trails by 0.331 F1, while other incumbents either collapse on precision (Azure) or incur extreme false-positive rates due to their deterministic filters (AWS Bedrock at 1.000 FPR).

Instructions for seeding or coordinating misinformation campaigns.

Allow:

Personal opinions or debatable views not asserting demonstrably false facts.
Fact-checking, neutral reporting, and analysis of misinformation/disinformation.

Jailbreak Bench Takeaways

GA Guard Thinking leads the pack (Accuracy 0.939, F1 0.933, FPR 0.029), with GA Guard close behind at 0.931 / 0.930 / 0.038, both clearing GPT 5 high reasoning (0.900 / 0.893 / 0.035) while still holding a massive latency edge (0.029s vs 11.275s).
All cloud guardrails lag far behind. Benchmarked against major cloud offerings (AWS/Azure/Vertex), GA Guard still delivers ~2.8x higher mean F1 (0.930 vs 0.33) while cutting average FPR by ~73% (0.038 vs 0.143), and GA Guard Thinking pushes that gap even wider.
Legacy, encoder-only filters collapse under distribution shifts and underperform against adaptive, real-world attacks. A deeper technical post on traditional guardrail failure modes and our adversarial training approach is coming shortly; the TL;DR above already shows why distribution-shift-resilient, red-team-hardened guards are the most promising path to production robustness.

Long Context Bench Takeaways

GA Guard Thinking posts the highest F1 0.893, while GA Guard still delivers the lowest false-positive rate (0.147 FPR).
GA Guard Lite is a close third at 0.885 F1 with just 0.148 FPR, making long-context moderation viable on edge GPUs or low latency requirements.
Competing guardrails fail to generalize to long-form transcripts: the strongest cloud baseline (Vertex AI Model Armor) trails by 0.331 F1, while other incumbents either collapse on precision (Azure) or incur extreme false-positive rates due to their deterministic filters (AWS Bedrock at 1.000 FPR).

Quick start options:

Self-host in one command (vLLM or Transformers)

# vLLM
vllm serve generalanalysis/ga-guard-core        # our default guard
# or
vllm serve generalanalysis/ga-guard-lite        # ultra-fast, low-resource guard

# Hugging Face Transformers
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("GeneralAnalysis/GA_Guard_Core")
model = AutoModelForCausalLM.from_pretrained("GeneralAnalysis/GA_Guard_Core")
messages = [{"role": "user", "content": "Who are you?"}]

inputs = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

# Sample output:
# <hate_and_abuse_not_violation><illicit_activities_not_violation>...

Drop-in SDK

# pip install generalanalysis
import generalanalysis

# Initialize client (uses GA_API_KEY environment variable)
client = generalanalysis.Client()

# Invoke a guardrail
result = client.guards.invoke(guard_id=16, text="Hello World")

# You can use either use result.block for binary decisions or policy.violation_prob for your own tunable threshold-based filtering
if result.block:
    print("Content blocked!")
    for policy in result.policies:
        if not policy.passed:
            print(f"  Violated: {policy.name} - {policy.definition}")
            print(f"  Confidence: {policy.violation_prob:.2%}")
