Ninja Crispi FN101ST vs AF101: Choose by Glassware and Cooking Modes

The FN101ST is the clearer fit if you want its included glass containers and lids for cooking and leftover handling, or you prefer its listed Max Crisp, Bake, Air Fry, and Recrisp presets. The AF101 is the documented fit if you specifically want a named Dehydrate mode and prefer a basket chamber. The sources do not establish that the FN101ST cannot dry food another way or that either fryer cooks food better.

The buying question

Which routine fits you better: the FN101ST’s included glass vessels for cooking and handling leftovers, or the AF101’s basket setup and its documented Dehydrate mode?

The FN101ST includes glass containers and storage lids, and its exact product page lists Max Crisp, Air Fry, Bake, and Recrisp presets. RTINGS identifies Air Fry, Roast, Reheat, and Dehydrate modes on its exact Gray AF101 review unit. Ninja’s FN101ST page does not list a dedicated Dehydrate mode; that omission does not show whether food can be dried in another mode.

Quick verdict

Choose Ninja Crispi 4-in-1 Glass Air Fryer in Stone (FN101ST) if

  • You want the FN101ST’s included 6-cup and 4-quart glass containers with storage lids and Ninja’s documented prep/cook/table/fridge workflow for its compatible 6-cup vessel.
  • The FN101ST’s listed Max Crisp, Air Fry, Bake, and Recrisp presets match your routine.

Choose Ninja Air Fryer 4-Qt in Grey (AF101) if

  • You prefer a basket-style cooking chamber over a glass cooking vessel.

When the recommendation changes
  • If a named Dehydrate mode is essential, AF101 is the model documented with that mode; the exact FN101ST page lists four other preset modes but does not establish whether another setting can dry food.
  • If carrying the cooking vessel through serving and leftover storage matters more than a named drying mode, the FN101ST has the clearer documented glass-container path.

The differences that matter

Cooking Control

Ninja Crispi 4-in-1 Glass Air Fryer in Stone (FN101ST)

Ninja lists Max Crisp, Air Fry, Bake, and Recrisp as FN101ST presets, with modes up to 450°F.[1]

Ninja Air Fryer 4-Qt in Grey (AF101)

RTINGS identifies Air Fry, Roast, Reheat, and Dehydrate modes for its exact Gray AF101 review unit, with a 105°F–400°F range.[4]

What this changes: The named mode menus differ. AF101 is the model with a documented Dehydrate mode; the FN101ST page does not list one, but that does not establish that the Crispi cannot dry food through another setting.[1, 4]

The better fit depends on your priorities

Cook Serve Store Workflow

Ninja Crispi 4-in-1 Glass Air Fryer in Stone (FN101ST)

FN101ST includes 6-cup and 4-quart glass containers and two storage lids. Ninja explicitly lists FN101ST as compatible with its 6-cup vessel and describes prep/cooking, carrying it to the table, and storing leftovers in the fridge.[1, 3]

Ninja Air Fryer 4-Qt in Grey (AF101)

RTINGS identifies the exact Gray AF101 as having a non-glass basket chamber. Ninja’s 103KY100 crisper-plate accessory is listed as compatible with AF101 and described as nesting inside an air-fryer basket; the accessory page does not establish the assigned retail box contents.[4, 2]

What this changes: The FN101ST has a documented path using an included glass vessel from cooking through table service and fridge storage. AF101 is documented with a basket chamber and a compatible nesting plate. This does not imply that AF101 cannot use separate serving or storage dishes.[1, 3, 4, 2]

The better fit depends on your priorities

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If you encounter a price gap, weigh it against the documented fit: the AF101 has a named Dehydrate mode, while the FN101ST includes glass vessels and lids for the described cooking-to-storage workflow. The available price evidence does not identify a better time to buy.

Comparable current offer evidence and a usable price history are unavailable here, so there is not enough information for a buy-now-or-wait recommendation.

Limitations

  • Ninja’s exact FN101ST page lists Max Crisp, Air Fry, Bake, and Recrisp presets but does not list a dedicated Dehydrate mode. This does not prove that the Crispi cannot dry food using another mode.
  • The AF101 crisper-plate page describes a compatible accessory; it is not evidence of what is included in every AF101 retail offer. The workflow comparison does not rely on the plate being in the selected box.
  • Pickoryx did not test either fryer, so this article does not say which one cooks food better or faster.
