Claude Opus 4 Pricing: Full Tier Breakdown (2026)

Claude Opus 4 family pricing has stayed flat at $5 input / $25 output per MTok across every minor release from 4.0 through 4.7 — a rare display of pricing discipline in a market where GPT-5.x and Gemini have cut prices multiple times. But "flat" is misleading: Opus 4.7's new tokenizer produces up to 35% more tokens for the same content, effectively raising costs 20-30% for coding and Chinese workloads. This breakdown covers all Opus 4.x variants, the three legitimate savings paths (prompt caching 90% off, batch API 50% off, context-window downsizing), and answers "how expensive is Opus 4 really" at 3 production scales. TokenMix.ai routes all Opus variants with transparent tokenizer-aware billing.

Confirmed vs Speculation

Snapshot note (2026-04-24): Historical SWE-Bench figures for Opus 4.0 → 4.7 in the lineup table are a composite of Anthropic launch-post numbers, Finout / finops community tracking, and vendor-reported gains. The "87.6%" for 4.7 specifically aggregates Anthropic's announced "+13% vs 4.6 on their 93-task benchmark" with community reproductions — read as directional/vendor-aligned rather than a single audited score. Tokenizer inflation ranges (10-35%) are measured on specific content samples; your workload may fall outside these.

Consistency: price unchanged across 14 months and 5 major releases. Anthropic's message: quality improves, pricing discipline holds.

The 3 Savings Paths

Path 1: Prompt Caching (90% off on cached tokens)

response = client.messages.create(
    model="claude-opus-4-7",
    system=[{
        "type": "text",
        "text": large_context,  # e.g., 100K tokens
        "cache_control": {"type": "ephemeral"}
    }],
    messages=[{"role": "user", "content": user_query}]
)

Cache valid 5 minutes. Subsequent calls within window: 10% of original input cost. Essential for RAG and long-context Q&A.

Path 2: Batch API (50% off)

batch = client.messages.batches.create(
    requests=[
        {"custom_id": "task-1", "params": {...}},
        {"custom_id": "task-2", "params": {...}},
    ]
)
# Returns within 24 hours at 50% cost

Use for async workflows: batch evaluation, bulk summarization, data processing.

Path 3: Downsize when context allows

• Use Sonnet 4.6 (60% cheaper) for 70% of queries → see Sonnet vs Opus
• Use Haiku 4.5 (84% cheaper) for simple tasks → see Haiku vs Sonnet

Cost at 3 Production Scales

Startup MVP — 10M tokens/month (80/20):

• Opus 4.7 raw: $90
• With 50% prompt caching on repeated context: $65
• With 30% Sonnet routing: $58
• Optimized: $40-50/month

Mid-size product — 500M tokens/month:

• Opus 4.7 raw: $4,500
• With caching + batch for 40% async: $2,800
• Multi-tier routing (30% Haiku / 50% Sonnet / 20% Opus): ,800
• Optimized savings: 60% off naive all-Opus

Enterprise — 10B tokens/month:

• Opus 4.7 raw: $90,000
• With aggressive caching, batch, routing: $35,000-45,000
• Additional tokenizer tax factor: +$8,000-11,000
• True optimized: $43,000-56,000/month

For enterprise, budget cost optimization as a dedicated engineering effort — typically worth 1 FTE to save 50%+ on bills.

Hidden Cost: The Tokenizer Tax

Opus 4.7's tokenizer update inflates token count relative to Opus 4.6:

Impact example: team spending 0,000/month on Opus 4.6 coding workload. Migrating to Opus 4.7: same per-token price, but ~27% more tokens billed → 2,700/month effective cost. Nominal price unchanged; effective cost up 27%.

Budget for this migration tax when upgrading.

Opus vs Other Premium Tiers

Opus 4.7 sits in a peculiar pricing sweet spot — more expensive than general-purpose frontier (Gemini 3.1 Pro at $4) but dramatically cheaper than specialty tier (GPT-4.5 at $90). For most "premium but practical" workloads, Opus 4.7 is the pick.

FAQ

How expensive is Claude Opus 4 actually per query?

Typical coding query (2K input + 500 output on Opus 4.7): $0.024 per query. Typical chat query (500 input + 500 output): $0.015 per query. At 1,000 queries/day, that's 5-24/day, $450-720/month.

Is Opus 4.7 worth 5-6× the cost of Gemini 3.1 Pro?

For coding-heavy workloads where the 5-6pp SWE-Bench advantage matters: yes, eventually. For general chat, RAG, or content generation: no — Gemini 3.1 Pro or Claude Sonnet 4.6 wins on cost-value.

Does prompt caching apply to system prompts only?

No — any message block with cache_control: {type: "ephemeral"} caches. System prompts, user context, RAG retrieval results, anything can be cached. Cache is segment-based, not full-message.

What's the batch API turnaround time?

Up to 24 hours per batch. Most batches complete in 2-6 hours in practice. Use for truly async workloads — don't expect real-time response.

Can I mix Opus 4.6 and 4.7 in the same product?

Yes. Some teams run 4.6 for routine coding (older tokenizer = cheaper), 4.7 for complex refactors (newer benchmark gains). Anthropic maintains 4.6 access through at least Q2 2027.

Is there an Opus 4.8 on the horizon?

Not announced as of April 2026. Anthropic typically releases Opus variants every 3-5 months. Expect 4.8 or 5.0 in Q3 2026.

Does the 1M extended context mode cost extra?

Yes. Extended context (1M) charges 2× input token price: 0/MTok instead of $5. Output price unchanged. See 200K vs 1M context guide.
