Anthropic / Premium / Sep 3, 2026
Best value Claude — agentic Sonnet speed with near-Opus capability.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You need the absolute top coding ceiling — Opus 5 leads SWE-bench Verified by over 20 points.
72.7% on SWE-bench Verified (vs Sonnet 4.6's 62.3% on the same eval) with launch promo pricing of $2/$10 through August 31, 2026
78.5% OSWorld-Verified computer use and 46.8% on Humanity's Last Exam with tools
1M-token context in the fast Sonnet latency class — Opus-adjacent quality without Opus latency
Clearly behind Opus 5 and Fable 5 on the hardest reasoning and long-horizon agent tasks
Updated tokenizer produces ~1.0–1.35x more tokens for the same text, so effective cost runs above sticker price
Strong backups depending on your budget, workload, and preferred tradeoffs.
The default model powering Cursor and Windsurf. 79.6% SWE-bench, 1M context window, and best-in-tier writing quality — all at $3/1M input.
Anthropic's new Mythos-class flagship and the most capable coding model anyone can use — 80.3% SWE-Bench Pro, an 11-point jump over Opus 4.8. 1M context, 128K output, native parallel subagents. Released June 9, 2026.
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.
OpenAI's September 3, 2026 frontier release — the first GPT-6 model and OpenAI's answer to Claude Fable 5.1 two days earlier. State of the art on computer use (OSWorld 2.0 72.6% in ~47% less time than GPT-5.6 Sol), agentic coding (Terminal-Bench 4.0 57.9%), and frontier math (FrontierMath Tier 4 97.6%). $10/$50 per 1M tokens, 1.05M context, 128K output, knowledge cutoff April 30, 2026.

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 students, what it is genuinely good at, and when we would steer you away from it.
The default answer for students — 98/100 on the writing axis, and the model we would start with unless the price below rules it out.
Anthropic's most agentic Sonnet yet — a fast 1M-context workhorse that narrows the gap to Opus-class quality at $3/$15, and the new default model on claude.ai.
You need the absolute top coding ceiling — Opus 5 leads SWE-bench Verified by over 20 points.
The best price-to-capability pick in the Claude lineup. Sonnet 5 replaces Sonnet 4.6 as the production default: markedly better agentic coding and computer use at the same standard price, with a $2/$10 promo through August 2026.

The fastest model in this shortlist for students. Pick it when turnaround is what your readers or users notice.
The default model powering Cursor and Windsurf. 79.6% SWE-bench, 1M context window, and best-in-tier writing quality — all at $3/1M input.
You specifically need desktop-control capabilities (GPT-5.5/GPT-5.4) or the absolute highest coding ceiling (Opus 4.7).
The best all-around model for most developers and writers. Strong SWE-bench, excellent writing, 1M context — all at $3/1M input. Hard to beat as a daily driver.

For students, Claude Sonnet 5 (Anthropic) is our pick. Best value Claude — agentic Sonnet speed with near-Opus capability. It costs $2/1M input and $10/1M output tokens, with a 1M-token context window — enough headroom for all but the largest students jobs. Claude Sonnet 4.6 is the closest alternative if it doesn't fit your setup.
Because the work it is built for overlaps closely with students: production agent loops that plan, call tools, verify output, and finish multi-step tasks and high-volume coding assistance at one-fifth of Opus 5's price. The best price-to-capability pick in the Claude lineup. Sonnet 5 replaces Sonnet 4.6 as the production default: markedly better agentic coding and computer use at the same standard price, with a $2/$10 promo through August 2026.
On a moderate month — 10M input and 2M output tokens — Claude Sonnet 5 runs about $40.00 at list price, with no batch or caching discounts applied, so treat that as a ceiling. It is also the cheapest option among the models compared here, so for students there is no cost argument for dropping to something weaker.
Clearly behind Opus 5 and Fable 5 on the hardest reasoning and long-horizon agent tasks. Updated tokenizer produces ~1.0–1.35x more tokens for the same text, so effective cost runs above sticker price. Avoid it if you need the absolute top coding ceiling — Opus 5 leads SWE-bench Verified by over 20 points. None of that rules it out for students on its own — but if one of those limits maps onto how you actually work, take the alternative on this page seriously rather than defaulting to the top pick.
