Why Compare All Anthropic Models Together
The Compare Prices tool is the fastest way to put a shortlist of LLMs in a single grid — input cost, output cost, context window, and quality score in stacked columns you can scan vertically. Provider dropdowns let you mix models across Anthropic, OpenAI, Google, Meta, DeepSeek, Mistral, and xAI without leaving the page. Picking between Anthropic's models — flagship, mid-tier, fast — is usually done by reading the provider's pricing page top-to-bottom, which buries the spread. The Compare Prices grid flips that: you check **every Anthropic model** in one dropdown and the grid lays them out side-by-side. Input cost across the lineup spans $1.00 to $15.00 per 1M tokens — a 15.0× spread you can scan in three seconds. This guide walks through the lineup model-by-model with the framing of "what do you give up to step down a tier."

The Anthropic Lineup, Top to Bottom
**Claude Opus 4** — $15.00 input / $75.00 output per 1M, 200K context, quality 85, tier **flagship**. flagship tier is for frontier-quality use cases where the per-token price is a rounding error against the value of the output. **Claude Sonnet 4.7** — $3.00 input / $15.00 output per 1M, 200K context, quality 80, tier **balanced**. balanced tier is the production-default zone — quality high enough for customer traffic, price low enough to scale. **Claude Haiku 4.5** — $1.00 input / $5.00 output per 1M, 200K context, quality 65, tier **fast**. fast tier is built for high-volume throughput at the lowest per-token rate the provider offers. All five attributes (input, output, context, quality, tier) live in the Compare Prices grid, which makes the cross-tier deltas obvious. Stepping from Claude Opus 4 (Q85, $15.00) down to Claude Haiku 4.5 (Q65, $1.00) saves 93% on input at a cost of 20 quality points — the right tradeoff if your workload tolerates the quality drop.
Where Each Anthropic Model Earns Its Place
**Claude Opus 4**: best for customer-facing premium experiences, complex writing/code, low-volume high-value queries where the cost is dwarfed by what the answer is worth. **Claude Sonnet 4.7**: best for production routing default — chatbots, RAG answer synthesis, structured output, anything that ships to real users at scale. **Claude Haiku 4.5**: best for high-volume classification, lightweight summarization, embeddings-adjacent tasks, prefilters and triage stages, draft generation. This isn't marketing copy — it's how the tier classification on TokenRate's filter panel actually slots them. If you've already filtered to a tier, the Compare Prices grid is the next step: check the relevant Anthropic models alongside their cross-provider peers (e.g., Claude Haiku 4.5 next to Gemini Flash, or Claude Opus 4 next to GPT-5 and Grok 4) to confirm you're not paying a provider premium.
Cost Multipliers When Stepping Up a Tier
Within Anthropic's lineup, the step-up multipliers are stark. Input: Claude Haiku 4.5 → Claude Opus 4 is 15.0×. Output: 15.0×. Quality: +20 points. The question to ask: is +20 quality points worth 15.0× the per-token cost? For agentic or accuracy-critical workloads, yes — quality wins are non-linear in user value. For high-volume classification or templated content, no — the cheaper model clears the bar. Use the API cost estimator to put a dollar figure on the step-up at your workload volume.
Compare-Prices Across Providers, Not Just Within
The most common mistake when picking within Anthropic's lineup is forgetting that cross-provider competitors may dominate the chosen tier. Once you've picked your Anthropic candidates, add 1-2 competitors from a different provider dropdown — for the balanced tier, comparing Anthropic's mid-model against Gemini 2.5 Pro and Claude Sonnet 4.7 is usually instructive. The Compare Prices grid was designed for exactly this multi-provider workflow. The grid pulls prices live from OpenRouter and quality from a blended Arena AI + Artificial Analysis pipeline — both refresh on a 60-minute incremental cache, so the comparison reflects current rates not a baked-in snapshot.
