Analytical Proof Tree & Suanpan Cost Matrix
Left: how reasoning DeepSeek R1 verifies hypotheses before answering. Right: visual cost comparison for 1 million tokens on suanpan abacus beads.
FOLIO A // <think> PROOF TREE
DeepSeek R1 Analytical Proof Tree
AXIOM 00
Problem: Find all prime pairs (p, q) satisfying p^3 - q^5 = (p + q)^2
BRANCH A [VALID]
Parity and modulo 3 analysis: when p != 3 and q != 3, the squared sum leaves remainder 1; testing q = 2.
BRANCH B [PRUNED]
Brute-force search without bounding p^3 > (p+q)^2 is pruned at step 2 as inefficient.
Q.E.D. // CONCLUSION
Unique prime solution: (p = 7, q = 3), since 343 - 243 = 100 = (7 + 3)^2. Proof verified in 14 steps.
FOLIO B // SUANPAN COST MATRIX
Minimalist Cost Matrix: 1M Tokens for Less Than a Cup of Tea
Each celadon bead on the suanpan rod illustrates how low 1 million DeepSeek input tokens cost on LeinGPT compared to legacy foreign APIs:
DeepSeek V4 Flash
Instant code & chat
7.5 / 15 ₽
DeepSeek V3.2
Everyday flagship
23 / 34 ₽
R1 Distill 70B
Fast reasoning
24 / 24 ₽
DeepSeek V4 Pro

60 / 130 ₽
DeepSeek R1

100 / 400 ₽
Foreign Flagship APIs
For comparison ($5 / $15+)
380 / 1150+ ₽
What does 7.5 ₽ per 1 million tokens mean in practice?
That equals roughly 1,500 pages of dense text or 30,000 lines of source code. A full module code review costs fractions of a cent.

REFERENCE SECTION // FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions About DeepSeek V4 & R1
Q01 How good are DeepSeek V4 and V3.2 for coding and writing?
DeepSeek V3.2 and V4 match top Western flagships on code and text benchmarks while costing 10-15x less (starting at 7.5 ₽ per 1M input tokens in V4 Flash).
Q02 Which model should I choose: V4 Flash, V3.2, V4 Pro, or R1?
V4 Flash (7.5 / 15 ₽) is ideal for instant code and everyday chat. V3.2 (23 / 34 ₽) and V4 Pro (60 / 130 ₽) excel at complex architecture and long specs. DeepSeek R1 (100 / 400 ₽) activates deep [think] chain-of-thought reasoning for math, logic, and bug hunting.
Q03 Why does the official DeepSeek site show "The server is busy" while LeinGPT works smoothly?
The official web chat throttles requests and disables R1 under heavy load. LeinGPT routes requests through priority commercial endpoints with load balancing for 99.9% uptime.
Q04 Do I need a Chinese phone number (+86) or VPN?
No. Signing in on LeinGPT takes 10 seconds via Telegram or Yandex and works directly in your browser without a VPN.
Q05 Is it safe to upload proprietary code and documents?
Yes. Requests run through LeinGPT encrypted infrastructure, private chats are never indexed by search engines, and your data is not used to train external models.
Q06 Is a monthly subscription required?
No. All DeepSeek models use pay-as-you-go billing from your balance strictly for actual tokens used - with zero recurring fees or auto-billing.
