Gemini 3 Pro — strengths

  • +2M token context — largest window among top-tier models
  • +True multimodal input: video, audio, image, text
  • +Very strong on structured output and JSON-schema enforcement

GPT 5.4 — strengths

  • +Better tool-use accuracy than GPT-5.3 with shorter outputs
  • +Native vision for screenshots, charts, and documents
  • +400k context — fits code repos and long conversations

Gemini 3 Pro — weaknesses

  • Code generation slightly behind Claude Sonnet 4.6 and GPT-5.4
  • At very long contexts, latency becomes significant

GPT 5.4 — weaknesses

  • Pricier per token than Sonnet 4.6 at comparable coding quality
  • Reasoning mode noticeably increases latency over standard calls
