How much does Claude cost? Anthropic Claude pricing ranges from $1.00 per 1M input tokens (Haiku 4.5) to the published $10.00 per 1M rate for Claude Fable 5 and Claude Mythos 5. Claude Sonnet 5 is $2.00 input / $10.00 output per 1M; Anthropic now calls that its standard price and cancelled the previously scheduled September increase. Prompt caching cuts cache-hit input cost by 90%.

Vomit's separate-LLM Claude 5 rewrite: the GPLv3 Claude Code hook sends Claude's already-generated message through a second OpenAI-compatible model. It has no published fee and recommends local GPT-OSS 20B, but it does not erase Claude output tokens already billed; local compute, latency, and rewrite fidelity remain buyer costs. The project publishes no controlled token-saving benchmark, and Anthropic's model rates did not change. See the cost boundary, risks, and Labs blocker →
Graft's 42% Claude Code token claim: the MIT-licensed context tool reports mean task tokens falling from 8,070 to 4,650 in its own 162-run Sonnet 5 benchmark. Graft has no published subscription or per-token fee, and Anthropic's model rates did not change; optional deep graph enrichment still uses the buyer's provider key. Treat 42% as a vendor-run workload result, not a universal grep discount. See the pricing boundary, benchmark audit, and buyer test →
You own Claude outputs, but model-training rights are narrower: Anthropic assigns customers its rights in outputs, subject to the applicable terms. Its current policy permits specialized, non-competing classifiers and tools, while prohibiting competitive general-purpose models, open-ended text generators, using outputs as training targets, and helping third parties do the same. The policy introduced no new model or training surcharge; separately, Anthropic made Sonnet 5's current $2/$10 rate permanent by cancelling its scheduled September increase. See the terms, allowed uses, and buyer checklist →
Claude Code's reported 12×–40× pricing gap: Anthropic did not change its model rates. The new buyer signal compares usage included with eligible Max seats against the counterfactual cost of the same recorded tokens at API list rates. Anthropic's current usage-based Enterprise plan separately bills every token at standard API rates on top of its seat fee, so teams should replay their own model and cache mix before migrating. See the evidence, caveats, and calculator →
How Claude's text watermark works: Anthropic says future Claude models will use a SynthID-Text-style statistical pattern in word selection—not hidden characters or user tracking—and supported PNG, JPG, and SVG files will use separate signed C2PA credentials. The mark should be stronger in long prose and weaker in short, factual, lightly edited, or code-heavy output. Anthropic says it adds no tokens, speed penalty, token-rate change, or marking surcharge; a detection API is coming but has no published access or price yet. See the mechanism, limitations, and developer checklist →
15-day Claude app rewrite buyer watch: Boris Cherny described an internal Claude Tag agent trying to reproduce Anthropic's Electron desktop app in Swift. The experiment was still running after 14–15 days, and no model snapshot, token count, spend, or finished artifact was disclosed. Anthropic's public API prices have not changed. Read what buyers can and cannot conclude →
Opus 5 buyer watch: Anthropic's official rate remains $5.00 input / $25.00 output per 1M tokens, but early Claude Code users report mixed tool and context behavior. Our current Labs run scored 47/49 with zero API errors and higher output use than Opus 4.8. Read the evidence and migration test plan →
New Claude 5 context guidance: Anthropic says it removed more than 80% of Claude Code's system prompt for Opus 5 and Fable 5 without a measurable loss on its coding evaluations. The pricing did not change, but shorter recurring context can reduce input-token cost and latency. Read the Claude 5 context engineering cost guide →
Sonnet 5 launched: Anthropic introduced Claude Sonnet 5 on June 30, 2026. For most production routers, Sonnet 5 is now the default Claude price/performance option below Opus 5 and Fable 5. Read Anthropic's announcement →
Anthropic's Claude models are known for strong reasoning, coding, and safety. In July 2026, Claude Opus 5 launched as the premium tier beneath Fable, while Sonnet 5 remains the price/performance route. Claude Mythos 5 remains a vetted trusted-access lane.
Claude pricing is generally higher than OpenAI across comparable tiers, but Anthropic competes on coding performance, agent reliability, long context in supported models, and aggressive prompt-caching discounts.
Claude Fable 5 and Mythos 5 (Latest Frontier Tier)
- Claude Fable 5 ($10.00 input / $50.00 output) - Anthropic's restored frontier Claude tier for the hardest reasoning, long-horizon agentic work, coding, and vision tasks. It supports 1M context and up to 128K output. Read the Fable cost example →
- Claude Mythos 5 ($10.00 input / $50.00 output) - Mythos-class trusted-access model. Anthropic describes it as the same capability class as Fable 5 with broader safeguards lifted for specific trusted use cases.
- Claude Opus 5 ($5.00 input / $25.00 output) - Premium Claude option for complex reasoning, agentic coding, and high-autonomy work. It replaces Opus 4.8 at the same standard token price and remains half the standard API price of Fable 5.
- Claude Sonnet 5 ($2.00 input / $10.00 output) - Best price-to-performance ratio in the Claude lineup. 1M context, up to 128K output, strong for everyday coding and production workflows. Anthropic says the launch rate is now the standard price.
JuliaHub's independent sealed simulation study adds a useful workload-specific check: Fable 5 led the physical-AI score, while GPT-5.6 Sol cost much less per trial. Use that result for engineering-agent routing evidence, not as a universal model ranking.
Claude Haiku (Budget Tier)
Haiku models provide the best value in Anthropic's lineup:
- Claude Haiku 4.5 ($1.00 input / $5.00 output) — Fast, capable, good for production workloads
- Claude Haiku 3.5 ($0.80 input / $4.00 output) — Popular mid-tier option, strong quality-to-cost ratio
- Claude Haiku 3 ($0.25 input / $1.25 output) — Anthropic's cheapest model. Great for classification, extraction, and high-volume tasks.
Prompt Caching Discounts
Anthropic's prompt caching is one of the most aggressive in the industry. Cache reads cost only 10% of base input price:
- Claude Fable 5 and Mythos 5: $1.00/M cached (vs $10.00 standard) - 90% savings
- Claude Opus 5: $0.50/M cached (vs $5.00 standard) - 90% savings
- Claude Sonnet 5: $0.20/M cached (vs $2.00 standard input) - 90% savings
Batch API offers an additional 50% discount, making Claude Haiku 3 batch pricing just $0.125/M input — competitive with the cheapest models on the market.
Legacy Models: Still Available, Often Expensive
Earlier Claude models like Opus 4.1 and Opus 4 remain available at $15.00/M input, which is more expensive than the newer Fable 5 tier. Opus 4.8, 4.7, and 4.6 are now previous-generation. There's rarely a good reason to use legacy models unless you have specific compatibility requirements.
How Claude Compares
Claude Fable 5 ($10.00 input) is the published frontier Claude tier. It is 2x Opus 5 and 4x GPT-5.4 input pricing, so it should be reserved for work where the extra capability materially changes the result. Opus 5 still matches GPT-5.5 input pricing and undercuts GPT-5.5 output pricing ($25 vs $30).
The real value proposition for Claude is coding quality, frontier reasoning, agent reliability, and cache economics. Many developers should route everyday work to Sonnet 5, escalate difficult work to Opus 5, and reserve Fable 5 for jobs where fewer failed agent loops justify the higher token rate.
For the absolute cheapest option, check DeepSeek's pricing at $0.28/M for their flagship model.
