Claude Opus 5 vs Qwen3.7 Plus
Quale scegliere e quando — verdetto curato, non una tabella di benchmark
Entrambi espongono una finestra di contesto da 1000000 token e accettano input testo e immagine con uscita testuale, quindi la differenza è soprattutto prezzo e forma: claude-opus-5 costa $5 in ingresso e $25 in uscita per milione, circa 12.5x e 15.6x i $0.4 e $1.6 di qwen3.7-plus, e le sue letture di cache stanno a $0.5 contro $0.08. Scegli claude-opus-5 quando ti serve la sua capacità di pensiero esplicita o fino a 128000 token di uscita in una chiamata; scegli qwen3.7-plus per lavoro ad alto volume o a contesto lungo, o quando i tuoi input includono video, che Opus non accetta.

Un solo prompt, entrambi i modelli — misurati attraverso il gateway

When reasoning is enabled, the model generates a hidden chain of "thinking" tokens before it writes the visible answer, and those internal tokens are billed at the output rate even though no one ever sees them — commonly 3–10x more tokens than the response itself. Because output tokens are priced several times higher than input tokens, that added volume hits us at our most expensive rate, which is why the bill roughly doubled while our request count stayed flat. The spend is controllable: we can cap the reasoning budget per call, route only genuinely hard requests to reasoning mode and cheaper models for the rest, and track cost per successfully completed task rather than cost per token, since a single correct answer usually beats three cheap retries plus human cleanup.

Enabling reasoning requires the model to generate extensive internal "thinking" tokens to process complex logic before delivering a final answer. Because our vendor charges us per token consumed, this hidden computational overhead effectively doubles our output volume for the exact same number of user requests. Consequently, our costs have doubled because we are now paying for the model's increased processing time to achieve higher-quality, more accurate results.

## Fixed version ```python def longest_run(xs): if not xs: return 0 best = 1 cur = 1 for i in range(1, len(xs)): if xs[i] == xs[i - 1]: cur += 1 else: cur = 1 if cur > best: best = cur return best ``` ## The bug The counters were tracking the wrong quantity: `cur` counted *matching adjacent pairs* rather than *elements in the current run*, and both counters started at `0` instead of `1`. Since a run of length *n* contains only *n − 1* adjacent equal pairs, every result came back one too small — `[1, 1]` returned 1, `[3, 3, 3]` returned 2 — and a single-element list returned 0 because the loop body never executed and `best` kept its initial value of `0`.

## Fixed Code ```python def longest_run(xs): if not xs: return 0 best = 1 cur = 1 for i in range(1, len(xs)): if xs[i] == xs[i - 1]: cur += 1 else: cur = 1 best = max(best, cur) return best ``` ## Bug Explanation The function has two related bugs rooted in how it counts run lengths. First, `cur` is initialized to `0` and only incremented on matches, so it counts the number of *transitions* between equal elements rather than the total elements in the run—a run of N identical items only reaches `cur = N − 1`, undercounting by one. This also causes the single-element case to return `0`, since the loop never executes and `cur` never increments. […]

```json { "company": "Meridian Robotics", "quarter": "Q3", "revenue_usd_m": 412, "growth_pct": 11, "guidance": "Withheld pending Q4 close" } ``` Notes on judgment calls: - **quarter**: "September quarter" is labeled Q3 because the text refers to an upcoming "Q4 close," implying a calendar-aligned fiscal year. No fiscal year is given. - **revenue_usd_m**: 412 is stated as constant-currency and hedged ("call it"), so it's approximate; the currency is not explicitly stated as USD. - **growth_pct**: "up eleven and change" means slightly more than 11, so 11 is a floor rather than an exact figure.

**Cross-Provider Prompt Caching** We're introducing Cross-Provider Prompt Caching in the API Gateway. Repeated system prompts, long documents, and few-shot examples are stored once at the gateway layer and reused across OpenAI, Anthropic, Google, and self-hosted models. Instead of paying full input token costs on every request, your application sends a cache reference, and the gateway rehydrates the context before forwarding it downstream. Why does that matter? Teams running high-volume agents and retrieval pipelines typically see input token spend fall 40 to 70 percent, with median latency dropping by several hundred milliseconds. Caches are scoped per project, encrypted at rest, and invalidated automatically when a prompt template changes. Enable it with a single header, and see the docs for TTL tuning and per-route controls.

Introducing PromptCache, our new API gateway feature designed to store and reuse prompts across multiple artificial intelligence providers. Have you ever noticed how repeatedly sending identical queries drains your budget and increases latency? PromptCache solves this by intelligently storing responses at the gateway level. When your application requests the same prompt from a different provider, the system instantly returns the cached result. This drastically reduces API costs and accelerates response times for your users. You can configure custom expiration times and set specific fallback rules for each vendor. You must stop paying twice for the exact same computation. Please upgrade your entire infrastructure today and experience much faster and cheaper integrations without changing a single line of your application code.

Qual è più economico, Claude Opus 5 o Qwen3.7 Plus?
Qwen3.7 Plus è più economico per input / 1m token ($0.4 contro $5, 13× di differenza). Altre righe potrebbero indicare il contrario — la tabella sopra riporta la scheda completa, e il costo reale dipende dal tuo mix.
Posso fare un A/B test di Claude Opus 5 contro Qwen3.7 Plus senza due integrazioni?
Sì. Entrambi sono serviti tramite lo stesso endpoint compatibile con OpenAI con una singola chiave API — il passaggio richiede la modifica della stringa del modello in una sola riga, quindi puoi instradare una frazione del traffico verso ciascuno e confrontare direttamente le fatture.
Claude Opus 5 e Qwen3.7 Plus supportano il prompt caching?
Sì — entrambi fatturano le letture in cache a un prezzo inferiore rispetto alla loro tariffa di input, quindi i carichi di lavoro con warm-prefix costano meno di quanto suggeriscano le tariffe di listino. Le righe esatte per la lettura in cache si trovano nella tabella dei prezzi qui sopra.
