Instant Pot Duo Plus 8L vs Breville Fast Slow GO

The decision

Both are stainless-steel pressure multicookers, and neither includes built-in air frying. The choice is therefore unusually clean.

Choose the Instant Pot Duo Plus 8L when 8L batch capacity is the requirement that changes your decision.

Choose the Breville Fast Slow GO when 6L is enough and Natural, Pulse and Auto Quick pressure release matters more than the extra two litres.

What changes the choice

Capacity is the durable difference

The Instant Pot uses an 8L 304-grade stainless-steel inner pot; the Breville uses a 6L stainless-steel cooking bowl. That two-litre gap matters when soups, stocks, family meals or meal-prep batches regularly make 6L feel restrictive.

If 6L already covers your cooking, extra capacity stops being decisive and the Breville's pressure-release workflow becomes more relevant.

Stainless steel does not separate them

Both governed records use stainless-steel cooking vessels. The Instant Pot inner pot is specifically 304-grade (18/8) and not stovetop-safe. The Breville record does not support an equivalent stovetop-use claim, so none is invented.

A stainless-steel preference keeps both on the shortlist; it does not create a winner or prove better cooking performance.

The pressure-release experience differs

Instant Pot uses an EasySeal lid with Easy Release Switch. Breville supports Natural, Pulse and Auto Quick release options.

These are different interaction models, not evidence that either appliance is objectively safer or faster. For frequent pressure-cooker users, Breville's named release paths can be the more meaningful distinction once 6L is enough.

Program counts and physical size have limits as comparison tools

Instant Pot lists 13 smart programs; Breville lists 14 shortcuts. A one-count difference is not a useful measure of capability or quality.

Breville is 31cm W × 35cm D × 33cm H. The current canonical Instant Pot record does not resolve dimensions, so this comparison cannot certify an overall compactness winner.

When Instant Pot Duo Plus 8L is the better fit

Choose it when a 6L pot would repeatedly constrain family or meal-prep batches and you want a stainless-steel pressure multicooker without built-in crisping.

When Breville Fast Slow GO is the better fit

Choose it when 6L comfortably covers your normal meals and Natural, Pulse and Auto Quick pressure-release options are a recurring ownership benefit.

When neither is the obvious fit

If built-in air frying is a core requirement, leave this pair. The Ninja Foodi OP350ANZ adds pressure + crisp through two lids, while the Ninja Foodi SmartLid OL650 puts pressure and crisping under one SmartLid.

PIQSY conclusion

Instant Pot wins the capacity decision; Breville becomes the better fit only when 6L is already enough and its pressure-release workflow is the feature you will use. Do not choose Breville because 14 is larger than 13, or Instant Pot simply because 8L is a larger number.
