excited to partner with u-blox, the $bn swiss chip company 🔓 they're putting AI agents on technical support their field engineers tested kapa on datasheets, dense pdfs, api refs and github code, plus our mcp in claude and cursor technical questions: days → minutes excited for what's next!

grep agents find the right docs just fine they just bring 24 friends on our bench, only 1 in 25 chunks a grep agent returns is actually needed full post from the research team below 👇

rerank-3 go brrrrrrr
“Voyage wins on score, cost, and latency.” Don’t believe us? Check out the latest benchmark from @kapa_ai. Frontier models keep getting better, but they aren’t the whole stack. Agentic systems constantly make smaller decisions: what to retrieve, where to route a query, and which results matter. Specialized models are often better suited to that work. Jev, @typesafeai’s general-purpose decision model, is a great example. Give it context, a question, and a set of labels, and it returns a probability for each label, allowing you to steer it with a rubric for routing, labeling, or ranking. @kapa_ai tested Jev as a reranker on 1,000 real-world evaluation cases built from production queries over company knowledge bases, including product docs, Slack threads, support tickets, wikis, and code. Jev wasn’t built for reranking, yet it came within a hair of first place on retrieval quality, while also beating several dedicated rerankers. Which model finished first? The rerank-3 model from Voyage AI by MongoDB topped the benchmark for retrieval quality while also being the cheapest and fastest model that Kapa measured.

it's still mindblowing to be that jev isn't a reranker but it performs like one

love to see this integration
introducing @LangChain × kapa your langchain agents can now search all your company knowledge more accurately, 3x faster and 8x cheaper than frontier models we synch docs, github, notion, slack, zendesk and more into a single index (with vectors + file system) your agent gets two tools: search everything, and read the full doc it takes 2 min for your agent to set up (+ free to try) just paste this into your agent: "set up a knowledge base for my agent using docs.kapa.ai/getting-started… and pip install langchain-kapa-ai to use official plugin" keep making agents go brr @hwchase17 + team!

we think this is a peak into the future of how agents will use the web :)
introducing WebMCP in kapa any agent that visits your website can now ask your company directly today agents scrape your pages and tries to convert them to markdown. it's the early mobile web all over again, pinching and zooming through sites built for someone else instead WebMCP lets your site hand agents a proper tool. answers come from your own knowledge with source links. and you get analytics! codex and chatgpt's browser already use it. chrome has it in an origin trial if you are an existing kapa user, it's a one line change for your widget: data-webmcp-enabled="true" if you aren't, you can try it for free for 14 days :)

we just killed RAG in n8n. introducing the official @kapa_ai node for @n8n_io no more: - chunkers, embeddings and vector stores to babysit - re-index jobs that quietly go stale - naive 2024 rag pipelines instead, kapa: ✓ connects all your sources to one index ✓ keeps it in sync by itself ✓ gets better answers in half the tokens and its free to try :)

introducing the official @kapa_ai for grok @bot stop your bots making up answers about your product connect your docs, help center and tickets once. every bot answers from them, and keeps up when they change. now you can easily build bots to: - answer support questions accurately - fill in security questionnaires from your docs - build sales coaches that review calls and coaches reps best part: your bot spots gaps in your docs and opens PRs to fix them :)
