SSI
Serializable Snapshot Isolation is the mechanism by which PostgreSQL implements a true Serializable isolation level. It guarantees serializability by actively detecting read-write dependency cycles and aborting transactions that could produce a non-serializable outcome.
Timeline (last 90 days)
PostgreSQL implements the serializable isolation level using the SSI (Serializable Snapshot Isolation) algorithm, detecting conflicts by identifying read-write dependency cycles between transactions, and once a conflict is found it rolls back one of the transactions and reports a serialization failure, which the application must retry.

In May 2024, OpenAI's superalignment team had essentially disbanded, with Ilya Sutskever leaving OpenAI to found SSI and Jan Leike joining Anthropic and criticizing OpenAI's safety culture for taking a back seat to products.
