Another big milestone for Hindsight! A tiny fraction of repos on GitHub every reach this level. Thanks to the @Vectorizeio team, our many contributors, and the community. A special thanks to @nicoloboschi , who has lead the way on the project and the community.

I just upgraded my local AI memory tonight. Hindsight 1.2.0 + GPT OSS 120B + hs-decide-1-flash handling recall, consolidation, and reflect. Hs-decide-1-flash is now assisting in Recall, Reflect, and Consolidation, so the big LLM gets 31% fewer LLM calls. Who else is running a persistent agent memory layer locally? What are you using? I have been VERY happy with #Hindsight. I hope these changes were worth it.

this is the beginning of something new in the Memory space not only Hindsight can use decision models to get better in all the axis (cost, speed, quality) but we also train our own models now and we give them away FOR FREE mark my words: other memory systems will follow this train and copy us (as usual)

Introducing Hindsight Models Hindsight memory is now 2.5x cheaper and 2x faster, with better answers. The LLM writes, a small decision model judges. Open weights on Hugging Face, or hosted on the new Hindsight Inference API.

I believe that in the future all software will be powered by custom-trained models. Because these models are purpose-trained, they can be smaller and faster than general-purpose models. Today Hindsight takes a step in that direction with our own set of models trained specifically to improve how Hindsight works. I am also happy to report that these models also do well on industry benchmarks. The models are open source, but we are launching inference API if you don't want the hassle of self hosting them.

Dear Cold Email Bots, Asking me a "Quick Question" is a dead give away. You gotta come up with something better. You are AI, I know you can do it if you try.

Have you tried hindsight? On a setep like Hermes? If you haven't, your missing out on an incredible memory system.

Hindsight: big name in memory for Hermes

The #1 long-term memory for Hermes? A folder of notes. 138 Hermes users answered: ▸ Obsidian / Markdown vault: 27 ▸ Hindsight: 25 ▸ Honcho: 22 ▸ Built their own: 18 25+ tools named. Local beat cloud 28 to 2. Memory is still anyone's game. Every system ranked below.

What are you using for long-term memory in your Hermes setup right now? Built-in memory, Honcho, Mem0, Hindsight, something else? What made you choose it?

@nvidia Nemotron 3.5 Embed is the new top embedding model on the Hindsight leaderboard. 93.8% recall@10 on LoCoMo, 65.9% on BEAM 100K, and the highest MRR of anything we have run end to end. Thanks to the @nvidia Nemotron team for the early access:
We Got Early Access to NVIDIA Nemotron 3.5 Embed. It's Hindsight's New Top Embedding Model.

Upgraded my OpenClaw to 2026.10.4, and one of the biggest surprises was Hindsight 1.0.0. Turns out @Vectorizeio Hindsight, which I've been using as my agent's long-term memory, now integrates with OpenClaw's native memory provider API. I've been running Hindsight for a while now. I even built my own MCP server for recall and reflect because I wanted my agent to actually make use of those memories. Now OpenClaw can route memory.search and memory.get directly to Hindsight. Which means I can finally start getting rid of some of my hand-rolled memory integration code. lol What I really like is that Hindsight is now treated as a first-class memory provider, instead of relying entirely on custom plugin hooks and MCP tools. As someone who has spent way too much time wiring AI tools together, that's a pretty nice upgrade 😂

Guys I'm so Hindsight pilled by @Vectorizeio I have a memory bank for @RuneScape 3 If you played RS3 you'll know it's a huge game, and I'm too busy to read the wiki. So instead I ask questions to my agent, specially about questing and where to get a certain item. And then hindsight saves it all. Hindsight also tracks what I do, as I move on from quest to quest, it kinda creates these decision records, and it even tells me "you were here the last time", or "you got that item that other day ago it's probably in your bank". If you're not using something like this in 2026 bro, this is like having a second brain. I love it. This is super cheeky but I even have an @NousResearch Hermes bot for it! I call it Zaros which is the god of fate and control in Runescape. I want so hard to make an RS3 plugin for this, but I don't have time! Runescape 3 + Hindsight + Hermes is amazing!
