Are You in the Weights?▲471
With more traffic moving off-web and into LLMs, I got curious about what traces we leave "in the weights". My design partner and I built a site in the past few weeks that checks recognition across frontier and small models. It queries many of them in parallel, clusters the responses, and tells you how strongly they recognize you. Happy to answer any questions here!

Echo – Fable-level results at 1/3 the cost using open-weight models▲484
I’ve been building Echo (https://echo.tracerml.ai/), an experiment in making one AI system out of a pool of open-weight models rather than choosing a single model and using it for every task. It started with a simple experiment. I took a group of models, including GLM-5.2, Kimi K2.7 and others, and ran them on the same evaluations. Then I measured what would happen if, for each problem, you somehow knew in advance which models would be useful and how their outputs should be combined. That hypothetical system performed substantially better than any individual model in the pool.…

YourGPT 2.0▲215
Today we are launching YourGPT 2.0, an update focused on making support, sales, and operational workflows work together more smoothly in one system. This release improves how workflows are built, how the platform connects to external tools, and how context is maintained across long, multi-channel interactions. AI Studio now makes it much easier to create and refine workflows. You can describe the process you want in natural language and the system generates the full workflow for you. It can also help debug issues by showing what happened at each step and explaining where things went off…

Parallel AI White-Label▲127
Thank you for checking out the product! This product is great for individual makers, teams, and enterprises to create content, code, images, and more as an alternative to ChatGPT. We offer access to the latest and greatest AI models, complete data privacy ensured, and support a huge (32k, 128k, 200k) context window for all of our plans. Compared to ChatGPT, who only offers 32k context window until you upgrade to enterprise, we offer A huge 4x upgrade to 128k for GPT4 and 200k for Claude. This allows all of our plans to ask questions against a huge 500 page documents or a set of documents. We…
