## Mirendil valuation surge
Mirendil, an AI startup founded by former Anthropic researchers, is in talks to raise new funding at a $5 billion valuation.
## Kleiner Perkins leading round
Kleiner Perkins is in talks to lead the round, which could bring in up to $1 billion in new capital.
## Fivefold valuation jump
The talks come three months after Kleiner Perkins and Andreessen Horowitz led a $200 million seed round for Mirendil at a $1 billion valuation, marking a fivefold jump in value in a single quarter.
## Recursive self improvement
Mirendil was started this year by former Anthropic staffers with the goal of building models capable of improving themselves with little human input, a technique known as recursive self-improvement.
## New model launch
The new capital would fund Mirendil’s own model and future training runs. The startup plans to launch a frontier model to support engineering and research work by early next year.
## Neo-labs wave
Thinking Machines Lab, founded by former OpenAI Chief Technology Officer Mira Murati, is in talks to raise at least $1 billion at a valuation of at least $40 billion.
## Key takeaway

Mirendil's valuation jumps fivefold in a quarter as it seeks $1 billion funding from Kleiner Perkins and Andreessen Horowitz.
