Excited to share that @deeptuneai is joining @mercor_ai. When we started Deeptune, we believed RL environments would become the defining bottleneck for AI. Over the past two years, we've seen this play out even faster than we expected. Mercor has built the world's leading expert network for AI, making it the obvious place to continue our mission. Together, we'll build the platform that powers the next generation of AI agents. Our entire team is joining Mercor in NYC, and we'll continue building with far greater resources towards the even bigger opportunity ahead. I'm deeply grateful to our customers, investors, and everyone who helped us get here. Most of all, thank you to the Deeptune team. None of this would have been possible without you. We're just getting started.



@OpenAI released GPT 5.6 today and we ran a day 0 benchmark in ParseBench to test improvements in document understanding. The new family of models continues to excel at reading text and tables, but continues to struggle with charts and layout. What's most interesting is that Luna is about 6 x cheaper than Sol and only results in minor degradations across all ParseBench metrics, showing that an increase in reasoning tokens doesn't always result in a commensurate improvement in visual understanding.

Meta just released Muse Spark 1.1 and is the new SOTA on MedScribe and TaxEval, taking the top spot from Fable 5 while being 10x cheaper and twice as fast. Meta currently holds the top 2 spots on TaxEval It is also the new #1 on Harvey's Legal Agent Bench, dethroning Grok 4.5 less than 24 hours after it took the top spot.



@tibor_tee you legend❤️

It took $165,000+ of Fable 5 API to port Bun from Zig to Rust. Wow!

We've partnered with SpaceXAI to train Grok 4.5. It’s our most powerful model yet and the first we've built for more than software engineering.
