Speed
What the numbers mean:
- Reasoning (9.5/10): GPT-5 Pro reaches state-of-the-art 88.4% on GPQA Diamond without tools and 94.6% on AIME 2025 math. GPT-5 with thinking produces roughly 6x fewer hallucinations than OpenAI o3 on long-form factuality benchmarks, making it the strongest mainstream reasoning model for high-stakes analysis work in 2026.
- Coding (9.4/10): On SWE-bench Verified GPT-5 clears 74.9% and Aider Polyglot 88%, making it the default production model at GitHub, Vercel, and Linear. GPT-5.3-Codex pushes Terminal-Bench 2.0 to 77.3% with the Codex harness, leading all agentic coding models for long-horizon repo tasks though Claude Opus 4.7 matches it on pure CursorBench.
- Multimodal (9.5/10): ChatGPT scores 84.2% on MMMU and leads on visual perception, spatial reasoning, and video understanding. Native image generation with the DALL-E successor, Sora video for Plus and Pro, and chart and diagram interpretation make ChatGPT the strongest multimodal assistant for creative and analytical work that crosses modalities.
- Writing (9.2/10): GPT-5 is a clear step up from GPT-4o for writing, with richer imagery, better rhythm, and less formulaic phrasing. Independent blind tests give Claude Opus 4.7 a small edge on literary prose, but GPT-5 is preferred for structured business writing, reports, emails, and long-form technical documentation.
- Speed (8.5/10): The unified router keeps the default experience fast by picking quick responses when reasoning is not required, while GPT-5 mini serves free-tier and high-volume API traffic with sub-second latency. Only GPT-5 Pro is noticeably slow, and only because it is intentionally spending extra compute on extended reasoning.
Key Features
Pros & Cons
| Pros | Cons |
|---|---|
GPT-5.3 Instant and GPT-5.4 Thinking cover most tasks cleanly Free and paid users get a fast default model, and paid tiers can explicitly switch into the stronger GPT-5.4 Thinking mode when a task needs more depth. | Pro tier at $200 per month is steep Unlimited GPT-5 Pro, Sora, and priority access are useful, but the price jump from Plus at $20 is aggressive for most users. |
Broadest multimodal surface in the market Native image generation, Sora video on Pro, Advanced Voice mode, vision, and chart interpretation all inside one subscription. | Claude Opus 4.7 still leads on large-codebase coding On CursorBench and complex multi-file refactors, Claude edges GPT-5 despite GPT-5.3-Codex closing the gap. |
Custom GPTs marketplace has no real competitor Millions of published custom assistants cover legal, SEO, sales, and niche workflows built by a massive community. | Heavy reliance on OpenAI infrastructure and policy Model deprecations, policy changes, and capacity limits during launches create real disruption for production workflows. |
Broad tool surface reduces app switching Web search, data analysis, file analysis, canvas, image generation, memory, and agent mode all live inside the same product. | Sycophancy reduction still imperfect GPT-5 is better than GPT-4o, but residual overagreement on opinion prompts remains a documented issue. |
ChatGPT Agent completes real tasks autonomously Browses the web, fills forms, and runs workflows inside a sandboxed browser with per-step user confirmation. | Custom GPT quality varies wildly The open marketplace means many GPTs are thin wrappers without real differentiation, requiring careful vetting before trusting one. |
