A dot is green when the detector's human-likelihood score for that run was 0.50 or higher. The detector rate is the mean of that detector's scores across the runs, the same number the detector pages rank by; it is not the count of green dots, which the Runs passed row shows. Hover a dot for the score.

How to read these scores

Each detector returns a human-likelihood on a common 0 to 1 scale, where 1 means it judged the text human-written and 0 means it flagged it as AI. On these pages a verdict counts as passed when that score is at least 0.50, the midpoint of the detector's own scale. That threshold exists only to draw the chips: the bypass rate on the leaderboard is the mean of each test's scores from the 6 detectors, a continuous number, so a tool's pass count and its bypass rate will not be the same figure.

# Introducing Solid Foods to Your Infant

Starting solid foods is a chance for your baby to explore new tastes and textures. Most infants are ready at around **6 months**. Before then, breast milk or infant formula provides the nutrition they need. Ask your pediatrician if your baby was born prematurely or has a medical condition that may affect feeding.

## Look for signs of readiness

Your baby should be able to sit upright with support, hold their head steady, show interest in food, and swallow it rather than push it out with their tongue. Age alone is not enough: wait until these skills are present.

## Start simply

Choose a time when your baby is alert and not overly hungry. Seat them upright and offer a small amount of soft food on a spoon, or let them pick up appropriately sized, soft pieces. Expect mess and very small portions. At first, eating is mostly practice; continue breast milk or formula as your baby’s main source of nutrition.

You can begin with mashed vegetables, fruit, beans, or meat; soft cooked foods; or iron-fortified infant cereal mixed with breast milk or formula. There is no required order. Include **iron-rich foods** regularly, such as meat, lentils, beans, tofu, and iron-fortified cereal. Offer a variety of flavors and gradually move from smooth textures toward mashed, lumpy, and soft finger foods as your baby develops.

## Introduce allergens thoughtfully

Once your baby is managing a few foods, offer common allergens such as well-cooked egg, yogurt, wheat, and peanut in forms that are safe to swallow. For example, thin smooth peanut butter with water or mix it into a purée; never offer a spoonful of thick peanut butter or whole nuts. Introduce one new allergen at a time so you can notice a reaction, and keep offering tolerated foods regularly. If your baby has severe eczema, an egg allergy, or another significant allergy concern, ask their clinician about introducing peanut.

## Keep meals safe and relaxed

Always supervise eating with your baby seated upright. Avoid choking hazards, including whole grapes, nuts, popcorn, hard raw vegetables, and round pieces of hot dog. Cut or soften foods as needed. Do not give honey before age 1 because of botulism risk, and avoid using cow’s milk as a drink before then. Limit added salt and sugar.

Let your baby decide how much to eat. Never force bites; turn away, close the mouth, or lose interest signals that they are done. With patience and repeated opportunities to try foods, your baby can build eating skills at their own pace.

Starting solids is a huge milestone for you and your child, but it is not something to stress over! Most infants are ready to start trying solid foods when they show signs of readiness, around 6 months of age, but it is not a “race” to achieve this milestone! Before then, breastmilk or formula is your baby’s only nutrition.

Look for signs that your baby is ready to start solid foods.

Your baby should be able to lift his head and his back should be strong enough to sit up straight. Age alone does not signal a baby's readiness for solid foods. You should also notice an obvious desire to eat the food you offer.

Start simply with rice cereal, mashed banana, avocado, etc., then progress to small pieces of fresh fruit or vegetables.

Choose a time of day when both you and your child are relaxed. It should be when you are both alert, but not at feeding time when your child is really hungry. Seat them in an upright position. Expect mess and be prepared to feed only a small quantity, maybe just a spoonful or two to start.

You can begin to offer baby cereal, pureed meats, fruits, and vegetables. Include iron-rich foods like meat and foods fortified with iron to help prevent iron-deficiency. Offer a variety of colors and textures of foods such as strained and mashed foods to increase the variety of foods your baby will eat. Later, you can move from mashed food to finely chopped or table foods.

Introduce allergens when your baby is ready.

Once your baby starts solids, it’s important to follow Canadian Society of Allergy and Clinical Immunology (CSACI) advice. Offer your baby these potential allergenic foods one at a time so you can spot any food allergies quickly and adjust their diet as needed: watch carefully for any symptoms that could indicate an allergy.

Keep meals safe.

Always supervise your child during meals. Have your child sit up while eating to avoid choking. Avoid choking hazards such as whole grapes, or raw vegetables. Cut or soften the food into smaller pieces. Avoid honey due to the risk of botulism.

Let your baby decide when they've had enough by watching for signs of fullness, such as turning their head away from the spoon and closing their mouth, and don't overfeed. Never force bites into your baby's mouth. Keep offering new foods on a consistent basis because acceptance can take time.

Each chip is one detector's score for that output, from 0 (AI) to 1 (human). A score of 0.50 or higher counts as a pass and shows green; below that the detector caught it and the chip shows red.

Penalties applied this cycle

How penalties work →

The overall score shown above already reflects these deductions.

  • Meaning drift ×10
    −10.0

    The output's meaning drifted significantly from the original input.

  • Length inflation
    −1.0

    The output ran much longer than the input, a common trick that pads text to dilute the AI signal.
