Flint is our first model built with the Eureka Machine, our automated research system, from scratch in 4 months.
We are betting that labs that automate AI research will outrun the labs that just hire more researchers.
Check it out today for fast, local and unmetered intelligence.
Introducing Flint, @Recursive_SI’s first model: a fast local coding model built with our automated research system, the Eureka Machine.
• Best-in-class fast local coding
• Up to 2x faster than comparable models: 125+ tokens/sec on a MacBook Pro, 150+ on RTX Spark
• Built from scratch in under 4 months
Private, unmetered intelligence on your own machine. Open weights available now on @huggingface, run it locally on your favorite framework or try it for free on @opencode or @pidotdev.
Excited for the big launch! Good time to share our podcast: youtube.com/watch?v=-A9SMRiV…
Today, we release our first model, Flint-40B-A2B, a fast local coding model built with our automated research system. huggingface.co/RecursiveSI/f…
1. Strong performance. 54.9% on Terminal-Bench 2.1, 89.7% on SWE-bench Pro v2, and 74.2% on SWE-bench Verified.
2. It is trained from scratch (tokenizer->Pretrain->Midtrain->SFT->RL).
3. Fast in your local laptop. Up to 2x faster than comparable models: 125+ tokens/sec on a MacBook Pro, 150+ on RTX Spark.
4. We build the complete model training pipeline in 4 month!

Coding taught AI how to execute.
Investing may teach it judgment.
@BillSun_AI believes financial markets could become the next training ground for machine intelligence. We explain why:

I think this name started from Ren-Tech in Quant trading?
Publishing a fun discussion (in Chinese) about Anthropic's Mythos model. Last time we had a chat on the topic of Anthropic in 2026 Jan when Anthropic is raising 350B valuation round, and I predicted there will be major correction for the whole enterprise software, especially SAAS sector.
This time at 2026 April 16, Mythos's launch made a splash, and recently Anthropic is raising 900B valuation round, let's try to make some prediction on what kind of impact on stock market that Mythos will have.
Top takeaways:
“Plaud is really about augmenting your professional life and giving you the freedom of perfect memory.”
“We index on people for whom the value of their time and presence is worth hundreds, if not thousands, of dollars.”
“We’re really trying to augment conversational intelligence, which most of the time involves two or more people.”
“We make uncompromising investments in our hardware so that the fail state isn’t your hardware.”
“We’re one of the only solutions that actually lets you store your own data on-premise.”
“We’re the only player in the space building our own hardware, our own speech-to-text pipeline, and our own infrastructure around it.”
“The magic of always-on agents is that they’re one step ahead of you, but in doing so, you compromise on your privacy and your agency.”
“The best device isn’t the perfect thing for someone 24/7, but the best thing for the task you have to do today.”
“Glasses are an incredible, very spiky form factor, but they’re not for everyone and they’re not for every scenario.”
“On-device is a necessary part of the future, from a privacy perspective and from a reliability perspective.”
