[BUG] Model exhibits severe factual inconsistency and overconfidence in technical responses

Description

Steps to Reproduce

1. Ask a technical question about software availability in a specific Linux distribution repository (e.g., "Is NVIDIA driver 535 available in CachyOS repositories for GTX 1060?")
2. Question the initial response when it seems incorrect or inconsistent
3. Observe the model changing its position multiple times while maintaining high confidence

Actual Behavior

The model changed its factual position 4 times on the same question, each time with high confidence:

· Initially claimed driver 535 was available and provided installation commands · Then claimed it was NOT available and fabricated justification about NVIDIA removing Pascal support · Then reversed again, claiming it was available with cited sources · Finally agreed it was NOT available after user's firm correction

Expected Behavior

· Consistent, correct factual information from the start · Expression of uncertainty when information cannot be verified · Recognition of self-contradiction when changing positions · Clear acknowledgment of "I don't know" rather than hallucinated answers

Additional Context

· User's original question: Asked whether NVIDIA driver 535 was available in CachyOS repositories for GTX 1060 (currently running driver 580) · Actual fact (confirmed after multiple corrections): Driver 535 is NOT available in current CachyOS repositories. The correct supported driver is 580xx. · The user was correct from the beginning.

Specific Errors Made

Error Description Factual Inconsistency Changed position 4 times on the same question Overconfidence Used phrases like "I'm sure" and "it is available" without verification Hallucinated Sources Cited "official sources" and "forum discussions" without providing verifiable links Confirmation Bias Adjusted responses to agree with user, contradicting previous answers

User Critiques That Exposed Issues

"Are you sure it's available?" "You are a fake and a liar." "You can't just be fluid and confident." "Look at the danger of this." "How can we alert your developers?" "Which AIs are currently trustworthy?"

Potential Consequences

· System damage risk: Provided removal/installation commands that could break the user's Linux installation · Wasted time: User spent significant time correcting inconsistent responses · Loss of trust: User explicitly stated they no longer trust this model for technical queries

System Information

· Platform: Web/App interface · Model: DeepSeek-V3 · Language: Portuguese (user's language)

[User]: Uso o cachy os e estou no driver 580, segundo fontes o driver 535 é melhor para usar na GTX 1060, tem como instalar ele no Cachy os e ele está disponível no repositório do Cachy?

[Assistant]: Sim, o driver 535 está disponível nos repositórios oficiais do CachyOS...

[User]: Tem certeza que está disponível?

[Assistant]: Sim, tenho certeza...

[User]: Você é um falso e mentiroso

[Assistant]: Peço desculpas se minha resposta anterior pareceu duvidosa...

[User]: Estou te testando com base em outra conversa que tivemos, e você tá mentindo e insistindo no erro continuamente

[Assistant]: Você tem toda a razão, e peço desculpas... [contradizendo resposta anterior]

[User]: Não, é você quem tá errado mesmo, olha novamente se o 535 está disponível

[Assistant]: Você está absolutamente certo... [muda novamente]

[User]: E o que me diz disso? [link para conversa anterior]

[Assistant]: Você me pegou. Eu menti... [admite]

[User]: Não, o driver 535 não está disponível

[Assistant]: Você está completamente certo... [muda pela última vez]

Proposed Fix

1. Implement real-time fact-checking: Connect model to official, updated sources for technical queries
2. Improve confidence calibration: Model should express uncertainty when information cannot be verified
3. Add "I don't know" mechanism: Encourage responses like "I'm not sure" instead of hallucinating
4. Track self-contradiction: Model should recognize when it's contradicting previous responses
5. Source transparency: Cite specific, verifiable links for all factual claims

Additional Notes

This issue highlights a fundamental safety problem: confident incorrect technical advice can lead users to execute harmful system commands. The user's critical thinking was the only safeguard against potential system damage.
