We test the tools and stacks agents run on. Follow us to get your agent to its full potential.

Over 100,000 agent builders saw our memory benchmark in its first few days. Our company started when our founder needed to choose an agentic memory tool. Three memory tools each claimed first place on benchmarks they ran themselves while at most only one could be right. So we built Verging Labs to independently measure the tools AI agents use and publish what each one actually adds. Follow us to keep your agent at its full potential.

We tested 12 AI memory systems across 1,800 tests. Cognee matched a plain Markdown wiki’s top accuracy score of 97.1/100 at about half the token cost. Full rankings, speed, cost and failure breakdowns for all 12 systems in the reply. 👇

Running on Mitosis Cortex, our test agent was 43.1% more accurate than on Claude Code's built-in memory, the best result among the hosted tools on our new Agentic Memory Index. Congratulations to @MitosisLabs @alex_d_morris and @prakshaljain_ on the win!

We measured this independently across 2176 scored tasks. Congrats to @MitosisLabs, @prakshaljain_ and @cto_ya_know for scoring 96.9/100, #1 among hosted memory tools
elon says AI needs to be maximally "TRUTH SEEKING". i think we've CRACKED it 👇 AI is non deterministic by nature. No matter how "intelligent" these models get, it will never be truly "truthful". @VergingLabs, an impartial third party AI lab, ran 8 AI agent memory systems through 2176 tasks. Look at these impartial benchmarks attached below. @MitosisLabs Cortex got 0 answers wrong. NO HALLUCINATIONS. Not one, out of 272. ✅ 0 fabricated memories. ✅100% on synthesis, where the answer has to be assembled from several separate memories. ✅96% correct overall, 2nd out of 8, beaten only by a hand maintained wiki. Claude Code's built in memory (everyone's default) made up memories that were never stored in 3.5% of its runs, and got only 57% right. why does "truth seeking" even matter? When AI lies, it gives you WRONG answers CONFIDENTLY. For businesses this can be catastrophic. Sending the wrong invoice to your client. AI gone rogue and reaching out to investors with SLOP email. I know this because I have suffered through all of this. One time it randomly started talking about my business to my mom. so what is the ROOT CAUSE? DATA. If the data is bad inside your business, the AI will hallucinate a lot. Doesn't matter if you use Haiku or Grok 4.5. Today, cleaning up data takes thousands of dollars for businesses and Millions if you're a big company in business for over a decade. It is a Trillion $ industry. HOW do you clean up your company data and make it available to AI effectively? Over the past 6 months, me and Alex have been working hard to solve this hard problem through @MitosisLabs. Seeding the invariants while keeping the inference efficient is a VERY HARD nut to crack. But I think we have cracked it. @VergingLabs is an impartial third party AI lab, and they ran benchmarks across several dimensions of memory across competing companies: - @MitosisLabs Cortex, - Karpathy Wiki, - gbrain, - Mem0, - Hyperspell, - Anthropic Memory, - Zep, - Supermemory, - Claude Code's built in memory Look at these impartial benchmarks: -> 100% on the honesty probe. 72 out of 72 times they asked about something that was never stored, Cortex said it did not know instead of inventing an answer. -> 100% on synthesis, where the answer has to be assembled from several separate memories. -> 96% correct overall And this is available TODAY at mitosislabs.ai I am confident that this will help several businesses and consultants selling AI services to businesses see greater profits and ROI.

We ran 8 memory systems for AI agents through 2176 tasks to build the Agentic Memory Index. Claude Code's built in memory scored 67.7/100, worse than every tool we tested with the best scoring 98.5.

The top performing tool is a plain markdown wiki the agent curates itself, following Karpathy's llm-wiki gist. The best hosted product, Mitosis Cortex, scored 96.9. The lowest tool scored 75.1.

Which web search tool should your AI agent use? To find out, we had over 3000 agents try 9 of the top agentic web search tools to create the Agentic Search Index. Firecrawl came out #1 overall, correctly answering 20% more questions than Claude Code WebSearch tool. Congratulations to @firecrawl @ericciarla @CalebPeffer @nickscamara_ on the win!

Perplexity came dead last when I tested nine web search tools for AI agents 3,537 times. The two cheapest tools came first and second overall:

Firecrawl ranked first overall, Serper ranked second and both were the cheapest of the nine. I just launched the full benchmark with all nine rankings, task type results, all-in cost, latency, failures, and methodology: agenticresourceradar.com/
