What’s New in 2025 : ChatGpt vs DeepSeek AI
GPT‑5 becomes the default in ChatGPT
OpenAI integrated GPT‑5 into ChatGPT as its new default model, superseding previous 4‑series and o‑series defaults. It balances quick responses with more “thinking” when appropriate and comes with new developer knobs such as reasoning_effort and verbosity. OpenAI+1
DeepSeek reduces prices and delivers V3.2‑Exp
DeepSeek V3.2-Exp came as an “intermediate” release with Sparse Attention to reduce compute, accompanied by a >50% API cost cut—down to $0.28 / 1M input (cache miss) and $0.42 / 1M output for chat, with $0.028 / 1M input on cache hits. DeepSeek API Docs+2Reuters+2
R1 reasoning receives peer-review focus
DeepSeek’s R1—a reasoning-biased model trained extensively through reinforcement learning—was featured in Nature, showing the ability of RL to uncover emergent “step-by-step” thinking tendencies. Nature+1
ChatGpt vs DeepSeek AI: Performance Benchmarks & Tests
OpenAI GPT‑5
OpenAI reports state‑of‑the‑art performance on coding and multimodal benchmarks (e.g., SWE‑bench Verified 74.9%, enhanced factuality, and 400K total context in the API). Although vendor‑reported numbers must be read in conjunction with independent testing, GPT‑5 is a clean improvement over o‑series and 4‑series on hard, tool‑using tasks. OpenAI
DeepSeek V3.2‑Exp / R1
DeepSeek’s most recent experimental model maintains competitive performance on MMLU‑Pro, AIME 2025, and GPQA‑Diamond, with improvements on agent benchmarks—all at lower cost. R1’s RL‑driven reasoning approach is a differentiator, now with peer‑reviewed exposure.Venturebeat+1
Bottom line: If you require the most dependable high‑reasoning agent available today, GPT‑5 is the safer bet. If you’re optimizing for cost per token and maintaining strong skills, DeepSeek is attractive.
Pricing: A Clear, Apple‑to‑Apple Comparison: ChatGpt vs DeepSeek AI
API token pricing (2025)
- ChatGPT (GPT‑5 API):
- Input: $1.25 / 1M tokens (cached input typically $0.125 / 1M)
- Output: $10 / 1M tokens
- Context: up to 400K tokens (272K input + 128K reasoning/output), API. OpenAI
- DeepSeek (V3.2‑Exp API):
- Input: $0.28 / 1M (cache miss) or $0.028 / 1M (cache hit)
- Output: $0.42 / 1M
- Context: 128K (V3.2‑Exp). DeepSeek API Docs
Concrete cost example (one short chat)
Imagine one exchange uses 2,000 input tokens and 2,000 output tokens:
- GPT‑5:
- Input: 2,000 ÷ 1,000,000 × $1.25 = $0.0025
- Output: 2,000 ÷ 1,000,000 × $10 = $0.0200
- Total ≈ $0.0225 per exchange. OpenAI
- DeepSeek V3.2‑Exp (cache miss):
- Input: 2,000 ÷ 1,000,000 × $0.28 = $0.00056
- Output: 2,000 ÷ 1,000,000 × $0.42 = $0.00084
- Total ≈ $0.00140 per exchange. (With a cache hit, input would drop to ≈ $0.000056.) DeepSeek API Docs
Takeaway: DeepSeek’s per‑token cost is dramatically lower. GPT‑5 costs more but brings a stronger safety stack, richer tools, and better end‑to‑end reliability for complex tasks. OpenAI
ChatGPT subscriptions (end users)
- Free: limited GPT‑5 access with caps
- Plus: $20/month
- Pro: $200/month
- Business/Enterprise: per‑seat plans with admin controls and compliance. OpenAI

Who Should Choose Which (Use‑Case Guide): ChatGpt vs DeepSeek AI
Pick ChatGPT (GPT‑5) if you:
- Run agentic workflows that chain tools (code repos, databases, web, spreadsheets). OpenAI
- Need long contexts (legal docs, research corpora, big PRDs). OpenAI
- Prioritize safety, auditability, and admin controls for teams. OpenAI
Pick DeepSeek if you:
- Care most about cost per token for high‑volume chat or support. DeepSeek API Docs
- Want open‑weight options to fine‑tune or deploy on your own infra. GitHub
- Focus on math/code/problem‑solving with tight budgets and can manage your own guardrails. Venturebeat
Real‑World Example: Support Bot at Scale
- Scenario: 1 million monthly chats at ~2K tokens each (input+output).
- DeepSeek V3.2‑Exp (cache miss worst‑case): 2K/1M = 0.002 × ($0.28 + $0.42) = $0.00140 per chat → ~$1,400 per 1M chats. DeepSeek API Docs
- GPT‑5: 0.002 × ($1.25 + $10) = $0.0225 per chat → ~$22,500 per 1M chats. OpenAI
If you require rigorous safety checks, improved tool usage, and extended contexts, GPT‑5 might be worth the increased expenditure. If you’re pushing the lowest cost per ticket solved, DeepSeek can’t be matched.
