OpenAI claims 86.6 % COBOL migration with GPT-6.1 Sol
In brief
- GPT-6.1 Sol migrates 86.6 % of tested COBOL programs, versus 5.4 % for GPT-5.6 Sol, per OpenAI.
- Cost savings come from a halved token price, despite 22 % higher token usage.
- On Vals AI, GPT-6.1 Sol ranks fourth for COBOL-to-Java migration, with lower per-test costs.
OpenAI states that GPT-6.1 Sol migrates 86.6 % of tested COBOL programs with byte-perfect outputs, compared to 5.4 % for GPT-5.6 Sol, according to an unpublished internal test. Cost savings are attributed to a halved token price, despite a 22 % higher token consumption. On Vals AI's Code Migration benchmark, GPT-6.1 Sol ranks fourth out of 26 models for COBOL-to-Java migration, with a lower cost per test than leaders according to ActuIA.
What it changes for you
- Industry & ManufacturingManufacturers could reduce costs for migrating COBOL systems to Java using GPT-6.1 Sol, pending business rule validation.
- Finance & BankingBanks and insurers could speed up modernization of critical COBOL applications, with an estimated 61 % cost saving per OpenAI.
- Public SectorGovernments could consider partial migration of COBOL systems to modern languages, based on OpenAI's claimed performance.
