Frontier Labs Reportedly Use RSI
Chubby says Google staff hint all frontier labs run recursive self-improvement loops, far ahead internally.
Key points
- Insiders say Google has either cracked RSI (recursive self-improvement) or is very close, going from GPT-5 level to Opus 5.5 level in months.
- Anthropic started a new pretraining run about a week ago, which is not Fable 5.5 but what would become Fable 6, or something bigger.
- Bel is the model behind the math results OpenAI published a few days ago, and RSI apparently helped there too.
- Google, Anthropic and OpenAI are all very close to cracking RSI or already have, according to the rumors.

Original post
Let's take this seriously: even Google employees are now clearly stating that it seems to be an industry consensus that all Frontier Labs are managing "RSI loops." In other words, recursive self-improvement is being implemented by everyone.
Furthermore, Fable 5.5 will be the best model for Anthropic's IPO, but internally, OpenAI's "Bel" will undoubtedly overtake Anthropic by the end of the year.
RSI is here, and internally, the labs are miles ahead.Quoting @PatrickToulme: I was at an AI dinner last night in NYC.
Some interesting topics discussed
1. Performance engineers now spend most of their time managing agents and RSI loops. Most perf opts at major inference providers (together, fireworks) are found by agents.
2. RLing too much on code and math has negative effects on your model especially it’s language.
3. People were impressed by @bot and the overall acqui

A blogger relays rumors that Google, Anthropic and OpenAI already use recursive self-improvement, raising questions about China and compute.
