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 grok 4.7 alternatives, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for grok 4.7 alternatives: 99/100 on coding, with the widest margin of anything in this line-up.
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 fastest model in this shortlist for grok 4.7 alternatives. Pick it when turnaround is what your readers or users notice.
Grok 4.7, released September 21, 2026, targets coding and professional knowledge work over multi-hour tasks, with better self-verification and long-context handling than Grok 4.6 at the same $2/$6 price.
You need a published SWE-bench score, or predictable cost per task — independent testing found its token use roughly doubled.
An incremental update. Grok 4.7 keeps Grok 4.6's price and gains a little on coding-quality tests, but independent runs found it spending far more tokens per task. Worth testing if you are already on Grok; not a reason to switch.

Claude Fable 5.1 is the strongest overall alternative. It scores 100/100 on research (Grok 4.7: 88/100) and costs $10/1M input vs $2/1M. Anthropic's highest-ceiling model — strongest on open-ended research; Opus 5.5 now leads coding.
Gemini 3.6 Flash at $0.75/1M input — 63% cheaper than Grok 4.7's $2/1M. It scores 91/100 on research, so expect a quality step down on the hardest tasks.
Yes — Kimi K3 is the strongest open-weight replacement for Grok 4.7, scoring 93/100 on research against Grok 4.7's 88/100. You can self-host it or run it through hosted APIs at $3/1M input (Grok 4.7 costs $2/1M), 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.
Grok 4.6 — same provider, same API surface, $2/1M input vs $2/1M. Finishes agent tasks in half the turns — cheap where it counts.
An incremental update.
