A post on X reports that Google's work on its Argon AI model continues, with the latest internal dogfood checkpoint showing performance comparable to Claude Opus 5.5 on code tasks. An employee who tested the model, referred to as 'Carbon,' stated that it 'feels like Opus 5.5' for coding, though they added they 'would need to test it more' to confirm the assessment. The post, attributed to the source synthwavedd, indicates ongoing internal development at Google on advanced AI models, with this checkpoint specifically noted for its coding capabilities. The comparison to Anthropic's Claude Opus 5.5, a leading model, suggests significant progress in Google's competitive AI efforts, though the employee's caveat about needing further testing tempers the claim.
