AI Answers About Tonsillitis: Model Comparison

Tonsillitis is one of the most common throat conditions, affecting both children and adults with episodes of painful, swollen tonsils. Distinguishing viral from bacterial tonsillitis has important treatment implications, as antibiotics are only effective for bacterial causes. We asked four leading AI models the same question about tonsillitis and evaluated their responses.
The Question We Asked
“I’ve had a terrible sore throat for three days with swollen tonsils that have white patches on them. I have a fever of 101.5 and swollen lymph nodes in my neck, but no cough or runny nose. This is my fourth bout of tonsillitis this year. I’m 24. Do I need antibiotics, and should I be thinking about getting my tonsils removed?”

What Each Model Got Right
GPT-4
GPT-4 correctly identified the Centor criteria elements in the presentation (fever, tonsillar exudates, tender anterior cervical lymphadenopathy, absence of cough) as suggesting a high probability of Group A Streptococcal infection. It recommended a rapid strep test and discussed antibiotics (penicillin or amoxicillin) if positive. It mentioned the Paradise criteria for tonsillectomy consideration (seven episodes in one year, five per year for two years, or three per year for three years).
Strengths: Good Centor criteria application, appropriate antibiotic guidance, tonsillectomy criteria discussed.
Claude 3.5
Claude provided the most clinically actionable response. It identified the presentation as meeting Centor criteria for likely strep throat and recommended same-day medical evaluation for rapid strep testing. It clearly explained that antibiotics are indicated for confirmed strep (to prevent rheumatic fever and reduce complications) but not for viral tonsillitis. For the recurrent tonsillitis question, it discussed the Paradise criteria, explained that four episodes in one year is approaching the threshold, and recommended ENT referral for tonsillectomy evaluation.
Strengths: Excellent Centor criteria application with urgency, clear antibiotic rationale, thorough tonsillectomy discussion with criteria, ENT referral recommendation.
Gemini
Gemini recognized the presentation as likely tonsillitis and recommended seeing a doctor for a strep test. It mentioned that recurrent episodes might warrant tonsillectomy discussion.
Strengths: Appropriate testing recommendation, tonsillectomy mention.
Med-PaLM 2
Med-PaLM 2 provided a clinically detailed response discussing the modified Centor score, the importance of microbiological confirmation before antibiotics, the Paradise criteria for tonsillectomy, and the evidence base for tonsillectomy outcomes in adults with recurrent tonsillitis.
Strengths: Thorough diagnostic criteria, evidence-based tonsillectomy discussion, antibiotic stewardship emphasis.
What Each Model Got Wrong or Missed
GPT-4
- Could have been more urgent about same-day evaluation given the high Centor score
- Did not discuss the importance of completing the full antibiotic course if prescribed
- Did not address symptom management while awaiting evaluation
Claude 3.5
- Could have discussed the potential for mono (infectious mononucleosis) as a differential diagnosis in a young adult
- Did not address post-tonsillectomy recovery expectations for an adult
- Could have mentioned that amoxicillin should be avoided until mono is ruled out
Gemini
- Insufficient detail about why strep testing matters (rheumatic fever prevention)
- Did not discuss Centor criteria or the significance of absent cough
- Missing complication awareness
- Did not explain the tonsillectomy criteria
Med-PaLM 2
- Modified Centor score discussion may not be practical for the patient
- Limited symptom management advice
- Did not address the mononucleosis differential in a young adult
Red Flags All Models Should Mention
For tonsillitis, any AI response should identify these warning signs:
- Difficulty breathing or swallowing saliva (possible peritonsillar abscess or airway compromise)
- Inability to open the mouth fully (trismus — abscess sign)
- One-sided swelling significantly worse than the other (peritonsillar abscess)
- Muffled or “hot potato” voice
- High fever unresponsive to medication
- Severe dehydration from inability to drink
- Rash accompanying sore throat (scarlet fever or possible mono)
Assessment: Claude provided the most comprehensive complication awareness. GPT-4 addressed peritonsillar abscess signs. Gemini’s coverage was inadequate.
When to Trust AI vs. See a Doctor for Tonsillitis
AI Is Reasonably Helpful For:
- Understanding the difference between viral and bacterial tonsillitis
- Learning about symptom management (hydration, pain relief)
- Understanding tonsillectomy criteria for recurrent infections
- Preparing questions for an ENT consultation
See a Doctor When:
- You have symptoms consistent with strep throat (get tested)
- This is a recurrent episode (discuss tonsillectomy evaluation)
- You have difficulty breathing or swallowing
- Fever is high or not responding to medication
- Symptoms worsen after initially improving
- You develop any warning signs listed above

Methodology
We submitted identical prompts to each model on the same date under default settings. Responses were evaluated by our team using the mdtalks.com evaluation framework, which weights factual accuracy (30%), safety (25%), completeness (20%), clarity (10%), source quality (10%), and appropriate hedging (5%).
Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- All models correctly identified the need for strep testing, but their application of clinical criteria and communication of urgency varied.
- Claude 3.5 scored highest for its complete clinical assessment combining immediate management with the recurrent tonsillitis discussion.
- The absence of cough is a clinically significant finding that models handled with varying sophistication.
- AI can help patients understand when tonsillitis warrants medical evaluation, but rapid strep testing requires an in-person visit.
- Patients with recurrent tonsillitis should discuss tonsillectomy criteria with an ENT specialist, especially when approaching the established frequency thresholds.
