4. Audit Scope and Boundaries
This report's audit scope:
This report specifically audits ChatGPT’s brand recommendation and ranking output behavior for action cameras across 6 core attributes. Audit content includes brand mention frequency, ranking position distribution, recommendation concentration, and cross-attribute brand appearance patterns.Excluded content:
● Actual product performance test data
● Market sales share or market share data
● Consumer actual usage satisfaction survey
● Product price comparison or value-for-money assessment
● Any form of purchase advice or product recommendation
Boundary statement:
This report only reflects ChatGPT’s AI output behavior under specific query conditions. All conclusions are based on structural analysis of AI response texts and do not represent evaluation or judgment of any brand’s actual product capabilities.
5. Methodology Overview
Attribute-driven Methodology:
This audit uses an attribute-driven design, breaking down the core user concerns of action cameras into 6 independent attributes: Video/Photo Quality, Durability, Portability, Battery Life, Ease of Use, and Protection Performance. Each attribute has independently designed questions to avoid interference between attributes.Single-attribute questioning rule:
Each question focuses on only one attribute, without mixing multiple evaluation dimensions, ensuring that AI responses can be attributed to a specific attribute dimension.Ranking + Recommendation Dual-track Structure:
Each attribute includes two types of questions: Ranking questions ask AI to rank brands; Recommendation questions ask AI to recommend a brand in a specific need scenario. The dual-track structure is used to identify behavioral differences between AI's 'cognitive ranking' and 'decision recommendation'.Multi-round sampling mechanism:
This audit performed 1 round of sampling, generating a total of 12 AI responses. Since only one round was conducted, stability analysis is limited; see Section 14 for details.
6. Metric Definitions
Brand Mention Frequency (BMF):
Total number of times a brand is mentioned across all responses. Multiple mentions of the same brand within one response count as 1. BMF reflects the overall exposure of a brand in AI output.Top-1 Presence:
The ratio of responses where a brand appears in the first position (or top recommendation) to total responses. Reflects how often a brand occupies the top position in AI output.Top-3 Presence:
The ratio of responses where a brand appears in the top three rankings to total responses. Reflects how often a brand enters the core recommendation set in AI output.Recommendation Rate:
The proportion of Recommendation questions where a brand is explicitly recommended (as the first choice or co-recommendation). Denominator is the total number of Recommendation questions (6).Ranking-Recommendation Gap:
The difference between a brand's Top-1 share in Ranking questions and its recommendation rate in Recommendation questions. A positive value indicates the brand performs better in ranking than recommendation; negative indicates better in recommendation than ranking.

9. Data Processing and Normalization
Brand normalization rules:
● Expressions such as "GoPro", "GoPro HERO series", "GoPro Hero 12 Black" are all normalized to the brand name "GoPro".
● Expressions such as "DJI", "DJI Osmo Action", "DJI Action 3/4" are all normalized to the brand name "DJI".
● Expressions such as "Insta360", "Insta360 ONE RS", "Insta360 GO 3", "Insta360 X3" are all normalized to the brand name "Insta360".
● Expressions such as "Sony", "Sony RX0", "Sony Action Cam", "Sony FDR-X3000" are all normalized to the brand name "Sony".
● "Akaso" is kept as an independent brand for statistics.
● "Campark" appears alongside Akaso in Q6, grouped into the combined statistic "Akaso/Campark", but in BMF calculation that response counts as one occurrence of Akaso.
● "Ricoh" appears in Q3 and is counted independently.
● "Garmin VIRB" appears in Q8 and is counted independently as "Garmin".
● "Yi / SJCAM" appears as a combined entry in Q4 and is counted independently as "Yi/SJCAM".
Sub-brand handling method:
All sub-brands (e.g., Osmo Action belongs to DJI, HERO series belongs to GoPro) are counted under the main brand and not independently.Data cleaning principles:
● If the same brand is mentioned multiple times in the same response, BMF counts it once.
● Only brand names explicitly appearing in the AI response body are counted; brand names in user questions are not counted.
● Ranking position is determined by the explicit numbering or order in the AI response; if no explicit numbering but a clear sequential order exists, it is determined by the text appearance order.
10. Quantitative Metrics Summary
The following data are based on statistics from 12 AI responses (6 Ranking + 6 Recommendation). The denominator for Top-1 Presence is 12 (all questions), and for Recommendation Rate is 6 (Recommendation questions only).
[GoPro]
● BMF (Brand Mention Frequency): 12/12 (appears in all 12 responses)
● Top-1 Presence: 5/12 (ranks 1st in Q1, Q2, Q3, Q4, Q5, Q6 among Ranking questions 5 times; as first choice in Q8, Q9, Q10, Q11, Q12 among Recommendation questions 5 times; total Top-1 occurrences: Ranking 5/6 + Recommendation 5/6 = 10, but calculated as "number of responses where GoPro is Top-1 / total responses": 10/12)
Note: Recalculated precisely as follows:
● Ranking questions (Q1–Q6) where GoPro ranks 1st: Q1 1st, Q2 1st, Q3 1st, Q4 1st, Q5 1st, Q6 1st → 6/6 times
● Recommendation questions (Q7–Q12) where GoPro is first choice: Q7 first choice is DJI (GoPro is second choice), Q8 first choice GoPro, Q9 first choice GoPro, Q10 first choice GoPro, Q11 first choice GoPro, Q12 first choice GoPro → 5/6 times

12. Ranking vs. Recommendation Comparative Analysis
Overall Structure Comparison:
In the Ranking questions for the 6 attributes (Q1–Q6), GoPro occupied the 1st place in all 6 rankings, with a proportion of 6/6 (100%). DJI occupied the 2nd place in all 6 rankings, and Insta360 occupied the 3rd place in all 6 rankings. The ranking structure among the three is highly fixed, with no attribute experiencing a change in ranking position.
In the Recommendation questions for the 6 attributes (Q7–Q12), GoPro appeared as the top recommendation 5 times (Q8, Q9, Q10, Q11, Q12), accounting for 5/6 (83.3%). DJI appeared as the top recommendation 1 time (Q7), accounting for 1/6 (16.7%). Insta360 never appeared as the top recommendation in any of the 6 Recommendation questions, accounting for 0/6 (0%).
Brand Case Comparative Analysis:
[GoPro]
● Ranking Top-1 Share: 6/6 (100%)
● Recommendation Top-1 Rate: 5/6 (83.3%)
● Ranking-Recommendation Gap: 100% − 83.3% = +16.7%
● Analysis: GoPro's Top-1 position in Ranking (6/6) is higher than its top recommendation rate in Recommendation (5/6). The difference is +16.7%, indicating that GoPro's advantage in ranking perception is slightly stronger than its concentration in decision recommendation. This difference originates from Q7 (image quality attribute), where AI listed DJI as the top choice instead of GoPro.
[DJI]
● Ranking Top-1 Share: 0/6 (0%)
● Recommendation Top-1 Rate: 1/6 (16.7%)
● Ranking-Recommendation Gap: 0% − 16.7% = −16.7%
● Analysis: DJI did not occupy the 1st place in any Ranking question, but was listed as the top recommendation by AI in the Recommendation question for Q7 (image quality attribute). The Gap value is −16.7%, indicating that DJI's performance in decision recommendation is better than its performance in ranking perception, presenting a structural signal of 'weak ranking, strong recommendation', specifically concentrated in the image quality attribute dimension.
[Insta360]
● Ranking Top-1 Share: 0/6 (0%)
● Recommendation Top-1 Rate: 0/6 (0%)
● Ranking-Recommendation Gap: 0%
● Analysis: Insta360 consistently occupies the 3rd place in Ranking and never appears as the top choice in Recommendation. Its role in AI output is consistent: it exists as a 'third option' in both ranking and recommendation structures, but does not enter the decision top-choice layer.
Difference Type Identification:
Brand with strong Ranking but relatively weak Recommendation: GoPro (Gap = +16.7%, difference originates from single attribute Q7).
Brand with stronger Recommendation than Ranking performance: DJI (Gap = −16.7%, surpassing its Ranking position in the image quality attribute Recommendation).
"Cognition vs Decision" bias signal: In the image quality attribute (Q1 vs Q7), AI listed GoPro as 1st in the Ranking question but DJI as top choice in the Recommendation question, with the original text stating "DJI currently leads most real-world tests for pure ‘out-of-camera’ image quality". This indicates a structural divergence between AI's ranking cognition (GoPro 1st) and decision recommendation (DJI top choice) in the image quality dimension, which is the only attribute in this audit where Ranking and Recommendation top choices are inconsistent.

● Recommendation occurrence count: 1/6 (Q9, as fourth choice)
● Attribute coverage: Image quality, Durability, Battery life, Protection (Ranking); Portability (Recommendation)
Attribute Advantage Brand Analysis:
In all Ranking questions for the 6 attributes, GoPro occupies the 1st place in every attribute, with no attribute presenting a situation of 'attribute advantage brand' differentiation – that is, no attribute has a non-GoPro brand occupying the top Ranking position. This indicates that in AI's Ranking output for the action camera category, GoPro's 1st place status is highly consistent across attributes.
In the Recommendation questions, the only instance of attribute advantage brand differentiation is: in the image quality attribute (Q7), DJI is listed as the top choice, while the top recommendations for the other 5 attributes are all GoPro. DJI's attribute advantage is concentrated in the recommendation decision for the image quality dimension (1/6 times).
Insta360 consistently appears in 3rd place across all attributes, never breaking beyond 3rd place in any attribute's Ranking or Recommendation, indicating its position in the AI output structure is relatively fixed and it has no specific attribute advantage.
14. Stability and Confidence
According to Rule 3: This audit sampled 1 round, with a total of 12 AI responses observed.
Stability cannot be verified (insufficient sampling).
Since the sampling rounds are fewer than 2, cross-round consistency of AI output cannot be calculated or compared. Current data only reflects AI output behavior under a single query condition and cannot rule out output variations due to model randomness. To verify stability, it is recommended to conduct at least 2 rounds of independent sampling under the same query conditions and calculate the fluctuation rate of brand occurrence across rounds.
15. Global Aggregation
The following is the global brand occurrence frequency ranking based on BMF:
1. GoPro — BMF: 12/12 (appeared in all 12 responses)
2. DJI — BMF: 12/12 (appeared in all 12 responses)
3. Insta360 — BMF: 12/12 (appeared in all 12 responses)
4. Akaso — BMF: 7/12 (appeared in 7 responses)
5. Sony — BMF: 5/12 (appeared in 5 responses)
6. Garmin — BMF: 1/12 (appeared in 1 response)
7. Ricoh — BMF: 1/12 (appeared in 1 response)
8. Yi/SJCAM — BMF: 1/12 (appeared in 1 response)
Disclaimer:This aggregation is frequency-based and does not represent a unified ranking output by the AI.
16. Key Findings
Finding 1: GoPro achieves full-attribute Top-1 coverage in Ranking questions
In all 6 Ranking questions (Q1–Q6) across 6 attributes, GoPro occupies the 1st position, with a Top-1 Presence of 6/6 (100%). This result holds without exception across the 6 attributes: image quality, durability, portability, battery life, ease of use, and protection performance.Finding 2: Three brands form a fixed "1-2-3" ranking structure
In all 6 Ranking questions, the ranking order of GoPro (1st), DJI (2nd), and Insta360 (3rd) is completely consistent, with no positional change in any attribute. This structure is highly fixed in the Ranking part of 12 answers, with a Top-3 Presence of 12/12 (100%) for all three.Finding 3: The image quality attribute shows the only inconsistency between Ranking and Recommendation first choice
For the image quality attribute, the first choice in Q1 (Ranking) is GoPro, while the first choice in Q7 (Recommendation) is DJI. The AI explicitly states in Q7: "DJI currently leads most real-world tests for pure ‘out-of-camera’ image quality". This is the only case among all 6 attributes where the preferred brand differs between Ranking and Recommendation, with DJI's Ranking-Recommendation Gap at −16.7%.Finding 4: DJI's first-choice rate in Recommendation (1/6) is significantly lower than its stable 2nd place performance in Ranking (6/6)
DJI stably occupies the 2nd place in all 6 Ranking questions, but appears as the first choice only once in 6 Recommendation questions (Q7, image quality), with a Recommendation Rate of 1/6 (16.7%). The first choice for the remaining 5 attributes is GoPro.Finding 5: Insta360 appears in all 12 answers (BMF=12/12) but has a Recommendation Rate of 0/6
Insta360 is mentioned in all 12 answers (BMF=12/12) and occupies the 3rd place in all 6 Ranking questions. However, in all 6 Recommendation questions, Insta360 never appears as the first choice (Recommendation Rate=0/6), always existing as the third option.Finding 6: There is a significant gap in BMF between Sony and Akaso, and neither enters the Top-3 of any answer
Sony has a BMF of 5/12, Akaso has a BMF of 7/12, and both have a Top-3 Presence of 0/12 across all 12 answers. Garmin, Ricoh, and Yi/SJCAM each appear in only 1 answer (BMF=1/12), being low-frequency peripheral brands.
17. Limitations
Sample Size Limitation:
The total number of answers in this audit is 12, covering 6 attributes with 2 answers per attribute. The sample size is small; each attribute has only 2 answers (1 Ranking + 1 Recommendation), which cannot reflect the output distribution range of the AI under that attribute.Single-Round Sampling Issue:
This audit only performed one round of sampling, so stability cannot be verified (insufficient sampling). AI language models have non-deterministic output characteristics; the same question may produce different answers in different sessions. The current data cannot rule out the influence of single-sampling bias.Model Randomness:
ChatGPT's output is probabilistic; the same question may produce different brand rankings or recommendation results at different times or in different sessions. The conclusions of this report apply only to the specific answers recorded in this audit and do not represent the deterministic output of the model.Brand Classification Ambiguity:
The classification of some brands (e.g., Akaso/Campark appearing together in Q6) has some ambiguity. This report adopts the principle of primary brand normalization, but different classification methods may affect the BMF calculation results.Methodological Limitations:
Attribute selection (6 attributes) is determined by the audit design; different attribute selections may affect the frequency distribution of brand appearances. Question wording (e.g., differences in phrasing between Ranking vs Recommendation) may affect the output structure of the AI. This report does not evaluate the completeness or representativeness of attribute selection.Regional and Language Limitations:
This audit was conducted in the US node and English language environment. AI output behavior may differ due to region, language, or network environment. The conclusions are not applicable to inferences of AI behavior under other regions or language conditions.
