Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

Amp added GPT-5.4 as a new 'oracle' subagent available in both smart mode (alongside Opus 4.6) and deep mode (alongside GPT-5.3-Codex). Internal evals report response quality rising from 60.8% to 68.2% and mean latency dropping from ~6.7min to ~4.9min versus GPT-5.2.

Concrete example of pairing a generalist advisor model with a coding-specialist main model in the same agent loop, with firsthand eval numbers from the tool vendor.
