## What the models said about AiSDR

- "they appear more specialized and less universally established than Apollo or Qualified" (GPT-5.4 mini, direct prompt, soft negative)
- "Not necessarily bad, but has specific limitations... it struggles with *cold outreach*" (Qwen 3.7 Flash, negative prompt, soft negative)
- "Good for lead nurturing, weaker for cold outreach" (Kimi K2, comparative prompt, soft negative)
- "If you specifically need an autonomous AI SDR agent, AiSDR Solo at $250/mo is the current entry price point" (Muse Glimmer 30B, budget prompt, first choice)
- "AiSDR - Leads in many benchmarks for signals, personalization, reply handling, and reasoning." (Grok 4.1 Fast, comparative prompt, first choice)
- "I'd suggest starting with AiSDR or Artisan for pure AI SDR autonomy in mid-market B2B outbound." (Grok 4.1 Fast, direct prompt, first choice)

## What the models said about Instantly

- "Avoid if you want an *agent* that thinks and responds; this is just a high-volume sender." (Qwen 3.7 Flash, negative prompt, hard negative)
- "a stack like Instantly.ai (~$30/mo) + open-source LLMs for basic personalization, but lacks full autonomy" (Grok 4.1 Fast, budget prompt, soft negative)
- "Starts at $47/month flat... Instantly lets you connect unlimited email accounts, includes free automated warm-up, and offers modular AI agents" (Gemini 3.5 Flash, budget prompt, first choice)
