Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for deepseek v4-pro alternatives, what it is genuinely good at, and where we would steer you away from it.
The default answer for deepseek v4-pro alternatives — 100/100 on the coding axis, and the model we would start with unless the price below rules it out.
Anthropic's September 1, 2026 frontier release and the new capability ceiling for coding, agents, and scientific work. Base pricing is unchanged at $10/$50, but cache reads dropped 75% to $0.25/1M — roughly 25% cheaper on typical workloads and up to 45% cheaper on agentic ones. 1M context, 128K output, adaptive thinking always on.
You need low latency, or your workload is uncached and cost-sensitive — Claude Opus 5 is half the base price and within a few points on agentic coding.
The new frontier leader, and the rare upgrade that costs less than the model it replaces. Base $10/$50 pricing did not move, but a 75% cut to cache reads makes typical workloads ~25% cheaper than Fable 5 and heavily agentic ones ~45% cheaper — while more than doubling Fable 5 on agentic science and beating Opus 5 on agentic coding. If you were already on Fable 5, switching is a straight win. If you were on Opus 5 for the price, it still costs 2x on uncached tokens.

The alternative to check next for deepseek v4-pro alternatives — 93/100 on coding.
DeepSeek's 1.6T-parameter (49B active) MoE flagship with hybrid sparse attention — near-frontier coding and reasoning at roughly a tenth of closed-rival pricing, MIT-licensed open weights.
You need vision input, verified agentic performance, or predictable pricing (surge pricing and an announced increase loom).
The open-weights frontier flagship of 2026. Self-reported numbers flatter it and independent agentic scores land lower, but even discounted it's the most capability per dollar in the directory's upper tier — with MIT-licensed weights.

Claude Fable 5.1 is the strongest overall alternative. It scores 100/100 on coding (DeepSeek V4-Pro: 93/100) and costs $10/1M input vs $0.435/1M. New frontier leader — better than Fable 5 on every published benchmark, and cheaper to run.
GPT-5.6 Luna at $0.2/1M input — 54% cheaper than DeepSeek V4-Pro's $0.435/1M. It scores 88/100 on coding, so expect a quality step down on the hardest tasks.
Yes — Kimi K3 is the strongest open-weight replacement for DeepSeek V4-Pro, scoring 96/100 on coding against DeepSeek V4-Pro's 93/100. You can self-host it or run it through hosted APIs at $3/1M input (DeepSeek V4-Pro costs $0.435/1M), with no per-seat subscription. Self-hosting trades the licence saving for infrastructure you have to run, so it pays off at sustained volume rather than for occasional use.
DeepSeek V3 — same provider, same API surface, $0.27/1M input vs $0.435/1M. GPT-4o-class coding quality at under $0.30/1M — the best value in the directory.
The open-weights frontier flagship of 2026.
