Best Alternatives to Zro: Uncensored Security Models in 2025
Zro by MoonMath.ai carved out a niche by serving 'abliterated' open models like Dolly 1 Security and Dolly 2 Security for defensive security testing and red-team workflows, with zero request retention and no training on customer data. But teams often need broader model catalogs, different pricing structures, or more mature infrastructure. Here are the best alternatives to Zro for uncensored security and coding model inference.
OpenRouter
OpenRouter aggregates hundreds of open and proprietary models behind a single API, including many uncensored and community fine-tunes. It offers flexible routing, transparent per-token pricing, and broad provider fallback, making it the easiest drop-in replacement if you want maximum model variety without managing multiple vendor accounts.
Together AI
Together AI provides fast inference for a large catalog of open models, including Llama, Qwen, DeepSeek, and GLM variants, with dedicated endpoints, fine-tuning, and strong privacy controls. It is a solid choice for teams that want production-grade infrastructure and coding models alongside security-oriented open weights.
Groq
Groq's LPU inference delivers extremely low latency for open models such as Llama and Mixtral, which is valuable for red-team automation and high-throughput security testing. If speed and predictable performance matter more than access to niche abliterated variants, Groq is a strong alternative.
Fireworks AI
Fireworks AI specializes in fast, scalable inference for open models with function calling, fine-tuning, and enterprise privacy options. It supports a wide range of coding and general models and is well suited for teams building security tooling that needs reliable API performance and custom model deployment.
DeepInfra
DeepInfra offers simple, low-cost serverless inference for many open models, including uncensored community variants, with per-token pricing and no long-term commitments. It is a practical option for smaller security teams that want broad model access and straightforward API integration.
Replicate
Replicate hosts thousands of community models and fine-tunes, including uncensored and security-focused variants, with easy deployment and pay-per-use pricing. Its model marketplace and custom deployment options make it useful for experimentation and red-team research where model diversity is key.
Anyscale Endpoints
Anyscale Endpoints provides scalable inference for open models like Llama and Mistral with enterprise-grade reliability and privacy. It is a good fit for organizations that need governed, production-ready access to open models for security and coding workloads without relying on a niche provider.
Zro stands out for its abliterated Dolly security models and zero-retention policy, but OpenRouter, Together AI, Groq, Fireworks AI, DeepInfra, Replicate, and Anyscale Endpoints each offer broader model catalogs, stronger infrastructure, or more flexible pricing. Choose OpenRouter or Replicate for maximum model variety, Together AI or Fireworks AI for production-grade open-model inference, Groq for speed, and DeepInfra or Anyscale for cost-effective or enterprise-governed deployments.
