§ 04 / BENCHMARKS
The numbers, not the spin.
Reasoning · GPQA Diamond
Real-world coding · SWE-bench Verified
A · DEEPSEEK
DeepSeek
The open-weight price leader — MIT-licensed, self-hostable, and cheap enough to change what you can afford to build.
Strengths
- Order-of-magnitude cheaper — $0.435/M input and $0.87/M output sit roughly 11× and 29× under Claude Opus 4.8
- Open weights — download V4 Pro from Hugging Face under MIT and run, fine-tune, or fork it without a per-token bill
- Data control — self-hosting keeps prompts, logs, and outputs on infrastructure you own
- Cache economics — a $0.003625/M cache-hit rate makes repeated-context workloads almost free to re-read
- Long outputs — 384K max output tokens, three times Claude's 128K ceiling
- Free to try — the consumer app costs nothing and advertises no message cap
Weaknesses
- Trails Claude on both neutral benchmarks on file — SWE-bench Verified 80.6 vs 88.6, GPQA Diamond 90.1 vs 93.6
- Text-first — no vision input, so screenshots, PDFs, and diagrams are out
- Hosted service stores data on servers in China, under PRC jurisdiction
- No native MCP, computer use, memory, Projects, or desktop app — you wire the tooling yourself
- No per-seat team plan and no published batch-API discount
Best for
- High-volume API workloads where token cost dominates the bill
- Teams that need on-prem or self-hosted deployment for data control
- Bulk generation, translation, and long-output jobs
- Fine-tuning an open-weight frontier model for a niche domain
- Chinese-language and multilingual applications
B · ANTHROPIC
Claude
The accuracy leader — the best scores on file for real-world coding, plus the deepest agentic tooling of the two.
Strengths
- Coding lead — SWE-bench Verified 88.6 vs 80.6, the widest quality gap between the two models
- Reasoning edge — GPQA Diamond 93.6 vs 90.1 on neutral leaderboards
- Agentic tooling — native MCP and computer use let agents reach your systems without custom glue
- Multimodal input — reads images, screenshots, and PDFs alongside text
- Cost levers — a 50% batch discount ($2.50 / $12.50) and cached input at $0.50/M soften the headline rate
- Team tooling — per-seat plans with SSO, admin, Projects, and memory
Weaknesses
- Far pricier API — roughly 11× on input and 29× on output against DeepSeek V4 Pro
- Closed weights — no self-hosting, no fine-tuning, no offline deployment
- The Opus 4.7+ tokenizer can use up to 35% more tokens for the same text, widening the real cost gap
- Opus is paid-only — the free tier runs a smaller model
- 128K max output caps very long single responses at a third of DeepSeek's ceiling
Best for
- Agentic coding where a failed step costs more than the tokens saved
- Hard reasoning tasks with a low tolerance for error
- Work involving screenshots, PDFs, and visual context
- Teams needing SSO, shared workspaces, and Western data residency
- Anyone wiring agents into internal tools over MCP
01
High-volume API product where tokens dominate the bill
You're shipping a summarisation or classification pipeline that burns hundreds of millions of tokens a month, and quality needs to be good rather than perfect.
Reasoning: The gap is roughly 11× on input and 29× on output. At that spread, DeepSeek's 8-point SWE-bench deficit is irrelevant to a workload that isn't writing patches — you're paying a 10× premium for accuracy the task never uses. Route bulk work to DeepSeek and keep Claude for the hard tail.
Picked
DeepSeek
Runner-up: Claude Opus 4.8 with batch pricing if output quality is the bottleneck
02
Engineer running autonomous coding agents
Your agent writes patches, runs tests, and iterates unattended — every failed step burns tokens, wall-clock time, and your attention when you review the mess.
Reasoning: Claude leads SWE-bench Verified 88.6 to 80.6 and adds native MCP plus computer use. In an agentic loop a wrong step compounds: a cheaper model that retries three times can cost more than the expensive one that lands first. The 8-point gap is where Claude's premium actually earns out.
Picked
Claude
Runner-up: DeepSeek for cost-sensitive or self-hosted coding pipelines
03
Enterprise that can't let prompts leave its own infrastructure
Compliance won't approve a hosted API in another jurisdiction, and the data in your prompts is the reason.
Reasoning: DeepSeek V4 Pro is MIT-licensed and downloadable, so you can run it entirely on hardware you control — prompts, logs, and outputs never leave. Claude is closed and API-only; its Western residency helps, but it's still someone else's server. For strict on-prem, DeepSeek is the only one of the two that qualifies.
Picked
DeepSeek
Runner-up: Claude Enterprise if a managed Western-region deployment is acceptable
04
Analyst working from screenshots and PDFs
Your inputs are scanned reports, dashboards, and diagrams — the text you need is inside images, not in a text field.
Reasoning: Claude reads images, screenshots, and PDFs natively. DeepSeek V4 Pro is text-first, so you'd bolt on a separate OCR step and inherit its errors before the model ever sees the content. Price is not the deciding factor when the cheaper model can't accept the input.
Picked
Claude
Runner-up: DeepSeek plus a dedicated OCR pipeline if cost outweighs the wiring
05
Startup on a fixed monthly ceiling
You have a hard budget, a small team, and a product that needs decent AI across a lot of requests rather than brilliance on a few.
Reasoning: DeepSeek's blended cost lets you serve roughly an order of magnitude more requests for the same spend, and its cache-hit rate of $0.003625/M makes repeated context nearly free. Claude's quality edge is real but narrow on general work — at a fixed ceiling, breadth of coverage beats a 3.5-point GPQA gap.
Picked
DeepSeek
Runner-up: Claude Pro at $20/mo for the founders' own hard problems
06
Team standardising on one assistant with admin controls
A dozen colleagues want one shared workspace, SSO, and a bill that arrives per seat rather than per token.
Reasoning: Claude Team is a real per-seat tier at $20–25/seat with SSO, Projects, and admin controls. DeepSeek has no per-seat app plan — teams self-serve on the API or run the weights themselves, which means someone owns that infra. For a team that wants seats today, Claude is the practical answer.
Picked
Claude
Runner-up: Self-hosted DeepSeek if you already have the platform team
Frequently asked.
Common questions about this comparison, with sources where they matter.
Q · 01 Is DeepSeek or Claude better overall? +
Neither wins outright — they optimise for different things. Claude Opus 4.8 leads on quality: GPQA Diamond
93.6 vs 90.1 and SWE-bench Verified 88.6 vs 80.6. DeepSeek V4 Pro leads on economics by more than an order of magnitude ($0.435 / $0.87 vs $5 / $25 per 1M tokens), ships MIT open weights you can self-host, and allows 384K max output. If accuracy on hard tasks decides your outcome, pay for Claude. If volume decides your budget, DeepSeek is hard to argue with.Q · 02 How much cheaper is DeepSeek than Claude? +
Roughly 11× on input and 29× on output —
$0.435 / $0.87 against Claude Opus 4.8's $5 / $25 per 1M tokens. The gap widens further on cached context: DeepSeek's cache-hit input is $0.003625/M versus Claude's $0.50/M, about 138×. It narrows if you use Claude's 50% batch tier ($2.50 / $12.50). Run your own workload through our LLM API cost calculator to see the difference in dollars.Q · 03 Is DeepSeek good enough to replace Claude for coding? +
It depends on whether a wrong answer is cheap. DeepSeek V4 Pro scores
80.6 on SWE-bench Verified against Claude's 88.6 — about 91% of the quality at under a tenth of the cost, which is an excellent trade for bulk or supervised coding. For autonomous agent loops it's a worse trade: a failed step costs a retry, and retries erase the saving. Many teams route both — see Claude Code vs Cursor for the harness side of the question.Q · 04 What does the 8-point SWE-bench gap actually mean? +
On a 500-task benchmark,
88.6 vs 80.6 is roughly 40 more tasks solved out of 500 — about one in twelve tasks where Claude lands and DeepSeek doesn't. That barely registers on everyday questions but compounds badly in unattended agent loops, where each miss triggers a retry. Weigh it against the ~10× price gap: for supervised work the cheaper model usually wins on total cost; for autonomous work it often doesn't.Q · 05 Can I use both? +
Most cost-aware teams do. The common pattern is a router (LiteLLM, OpenRouter) that sends bulk, templated, or low-stakes calls to DeepSeek and reserves Claude for hard reasoning, agentic coding, and anything with an image in it. Because the price gap is over 10×, even routing 80% of traffic to DeepSeek cuts a bill substantially while keeping Claude's accuracy where it matters.
Q · 06 Which has the larger context window? +
They tie — both DeepSeek V4 Pro and Claude Opus 4.8 carry a
1M-token window at standard pricing. DeepSeek wins on the other end: 384K max output tokens versus Claude's 128K, which matters for bulk generation and long translations. For very long inputs, test with your own material — usable recall varies by model regardless of the advertised ceiling.Q · 07 Does the tokenizer change the real cost gap? +
Yes, and it widens it. Anthropic notes that Opus 4.7 and later use a newer tokenizer that can consume up to 35% more tokens for the same fixed text. Since you're billed per token, not per character, that inflates Claude's effective rate on prose-heavy work on top of the headline difference. The Real cost / 1M chars row in the pricing table above adjusts for this — it's the honest comparison.
Q · 08 Is DeepSeek safe for privacy and regulated use? +
It depends entirely on how you run it. DeepSeek's hosted app and API store data on servers in China, under PRC jurisdiction — a genuine blocker for many regulated buyers, and several governments restrict it for official use. Because the weights are MIT-licensed and downloadable, you can self-host and keep everything on your own infrastructure, which is stricter than anything Claude offers. Claude is closed but Western-hosted with SOC 2 and SSO. Pick based on which of those two shapes your compliance team accepts.
Q · 09 Which is better for non-English work? +
DeepSeek is trained China-first and is strong in Chinese and across major languages; Claude is broadly multilingual. For Mandarin-first products DeepSeek has the edge, and its open weights let you deploy in-region. For most European languages the two are close enough that price, tooling, and residency should decide it instead.
