These models are significantly cheaper than competitors like GPT and Claude, with DeepSeek-V4-Flash costing $0.14 per million input tokens compared to $0.20 for GPT-5.4 Nano, because DeepSeek focused on efficiency improvements that reduced computational requirements.","solution":"N/A -- no mitigation discussed in source.","labels":["industry"],"sourceUrl":"https://simonwillison.net/2026/Apr/24/deepseek-v4/#atom-everything","publishedAt":"2026-04-24T06:01:04.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":["DeepSeek","OpenAI","Google","Anthropic","Unsloth"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-04-24T06:01:04.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
