Claude Science but with any model you like including local models. In use already by thousands of scientists worldwide. Please repost. github.com/K-Dense-AI/k-d…

@sama Very good model. Thanks for keeping it usable for scientific applications especially in the life sciences.
English

@OfficialLoganK We agree! And I think the most valuable and hardest to obtain right now is scientific data.
English

A combination I'm excited about if it is not cost prohibitive: @PidevCoding + @OpenAI GPT 5.6 Sol running on @cerebras.

RT @kdensemaya: POV: you’re using @k_dense_ai BYOK as your research assistant 🧬
In this vlog, I walk through how I'm using BYOK — from org…

First episode of the muniverse, a podcast by @muni_bio focusing on frontier science.
Synthesis might be the most underrated bottleneck in drug discovery. While everyone is racing to build better AI models for molecule design, @onepot_ai is building a world where molecules can be designed, made, tested, and shipped on demand.
I sat down with onepot co-founders @daniil_boiko and @andrei_tyrin, alongside my co-founder @derekalia.
00:00 - What onepot actually does
00:16 - Why synthesis became the bottleneck
02:52 - The Moscow lab origin story
04:41 - Why CRO timelines take months
07:00 - How automated is the chemistry stack?
08:58 - Where humans still beat robots
11:14 - The hidden labor behind “automated” labs
13:58 - Drug discovery vs materials
15:53 - Small molecules beyond pharma
17:09 - Why small molecules are harder than biologics
18:26 - The 10-year chemistry bet
20:47 - Personalized medicine needs faster synthesis
21:56 - Predicting toxicity before human trials
23:20 - Oil, ore, polymers, and drugs
26:28 - Why complex chemistry is still underbuilt
30:47 - Zero-person biotechs
33:32 - 3D molecules, cages, and exotic reagents
36:30 - The US-China chemistry advantage
38:20 - onepot in plain English
40:45 - Why biotechs outsource chemistry

Today, we're shipping 4 new capabilities for Managed Agents in the @GoogleDeepMind Gemini API! Background Execution, Remote MCP servers, Custom Function Calling and credentials refresh.
⏱️ Run long-running tasks asynchronously on the server (`background: true`)
🔌 Connect agents directly to internal endpoints via remote MCP servers
⚙️ Combine server-side code execution with local custom function calling
🔑 Refresh API tokens across turns without resetting your sandbox state
We're optimistic about making agents true background teammates rather than interactive chatbots. Let me know what you think, feedback has been incredibly helpful so far!

@s_lauermann Also give K-Dense Web from @k_dense_ai a shot! Comprehensive review with graphical explanations and citation checks.

Here is a brief idea for using GPT-5.5 Pro to systematically proofread a paper. I just sent it to a graduate student. Maybe useful for others, too, given the approaching job market paper writing season:
Prompt 1:
Help me audit and review the attached chapter/paper in depth.
Write me N proofreading prompts in code boxes/markdown file that I can give to N AI agents to work on.
Ensure overlap for critical tasks. Do not try to be smarter than the AI agent. The main job of the prompts is to distribute the tasks and ensure diligent, in-depth auditing work by the AI agents.
Parallel Prompt 2a,...,2n
Work on this task (copy and paste the previous prompt)
Parallel Prompt 3a,...3n:
Take another pass over your writing and check it critically. For each major issue
(i) provide counterexamples or repairs and
(ii) discuss why you may be wrong.
Parallel Prompt 4a,...,n
Make a Markdown with all your comments. Include concrete replacement suggestions where appropriate. Include anchors in the PDF for easier location. Double-check what you wrote.
Prompt 5a
Here are n Markdown files with comments. Merge them.
Prompt 5b
Write the comments as replyable comments directly into the PDF.
Your work
Read the comments in the PDF. You could then reply to each comment, save it, and then give the PDF with your instructions to codex/pro for implementation.
Notes:
(i) Use a project and upload the pdf/latex of the paper as a source.
(ii) This sort of workflow makes sense only for 5.5 Pro Webchat. You won't need it for an agent like Fable in cowork (if you have the usage left). Similarly, you would not need it for codex --- but codex gives only access to thinking, which seems weaker, especially for math.
(iii) Be respectful of the costs of 5.5 pro. Keep N modest, do not automate the browser workflow, and stay within normal interactive use. This is a manual quality-control workflow, not a scraping or batch-generation setup.

(Fable 5 + 1000 tokens/sec - bio filter) would be groundbreaking for AI co-scientist platforms. Will we see it from @OpenAI today?

@meowmeow_lingo @SynScience We cannot support all local model providers. We have to choose one only to make maintenance and improvements more practical for us as a small time. Sorry.
English

@TimothyKassis @SynScience But why? At least for me LMStudio is much more convenient, I have preferred models there. But now I have to download all this stuff the second time for Ollama just to try things out

Introducing OpenScience. A better, open-source Claude Science.
• Any model: GLM, Kimi, DeepSeek, Claude, GPT, your own fine-tune. Switching is one flag.
• 250+ research skills across ML, comp bio, cheminformatics. All readable, editable, extensible.
• No throttling, no gatekeeping, no one vendor deciding what science is okay.
• Native Atlas integration: many agents, one shared reproducible research graph.
• Runs on your infra. Your data stays yours.
Scientific AI should be open. One company shouldn't own the tools the rest of us discover with, or decide who gets to.

@TimothyKassis @SynScience It does not allow me to use lmstudio as provider. Only ollama.

Introducing Claude Science, a new app designed with every stage of research in mind. Artifacts traced to their code, environments managed on demand, and 60+ optional scientific databases that you can connect. Available now in beta.

@kareem_carr And open source much more capable version already exists. It's called K-Dense BYOK by @k_dense_ai github.com/K-Dense-AI/k-d…

I'm a little confused about who this product is for.
Scientists who already know how to code can probably figure out Codex or Claude Code.
Scientists who don't know how to code should probably learn enough coding first, rather than churning out things they don't really understand.
This product feels like it's trying to be a one-stop shop for doing the whole research project, which makes me feel a little locked in.
Personally, I'm already uneasy about being locked into Anthropic's ecosystem, especially after the Fable 5 refusal issues, so I would much rather use tooling that's model-agnostic.

试了一下 Claude Science,感觉很适合做科研早期调研。它会把一个研究问题拆成多个检索面,连接 OpenAlex、arXiv 这样的文献库,抓取真实文献数据,然后自动去重、过滤、聚类、画图,最后生成一份带主题地图、增长趋势和代表性论文的研究报告。
我让它分析 human-AI collaboration,它先抓了 2301 篇文献,清洗后留下 1711 篇,再自动分成 10 个主题社区,并生成了完整的研究地图。
对于刚进入一个领域、想快速知道“这个领域有哪些方向、谁在做、哪些论文重要、趋势在哪里”的人来说,非常有帮助。
当然它不能替代严格的系统综述,但作为科研初步调研和选题探索工具,效率非常高。
