Release Notes
Plaid Speed Amp now supports Plaid speed for modes that use GPT-6 Astra. Plaid uses OpenAI's ultrafast speed tier, which enables inference requests to run up to 6× faster, with 6× cost per token. Open the mode picker in the new thread dialog, choose a mode that uses GPT-6 Astra (e.g., the default High mode), and move the speed switch past Fast to Plaid. Plaid currently works with Amp-provided inference only, as OpenAI does not yet support ultrafast for linked ChatGPT subscriptions. When Plaid is activated, subagents and non-Plaid-enabled model inference will fall back to fast or standard speed. Like fast mode, Plaid can be toggled on or off for an existing thread.
