Compare AI Models by Price Tier

Compare AI models by price-to-capability ratio. Three tiers, clear tradeoffs, no marketing fluff.

Model Tiers

Budget Tier: Under $1/1M Tokens

Price: $0.25–$1.00 per million input tokens
Best for: Prototyping, preprocessing, hobby projects, high-volume workflows

Models:

• GPT-6 Luna — current high-volume OpenAI route; check the GPT-6 Sol/Luna owner guide for live access and pricing; measure CAR before production routing
• Gemini 3 Flash — FREE input tokens, 1M context, 78% SWE-bench
• GPT-5 mini — $0.25/1M, cheapest OpenAI option
• Kimi K2.7 Code — $0.95/1M cache-miss input, cheaper routine Kimi coding API lane
• Claude Haiku 4.5 — $1.00/1M, fastest responses

Bottom line: Compare cost per successful task. Do not turn scores from different benchmark variants into one percentage of “frontier performance.”

Mid-Range Tier: $1–$3/1M Tokens

Price: $1.00–$3.00 per million input tokens
Best for: Production apps, daily coding, reliable reasoning

Models and lanes to compare:

• Claude Sonnet 5 — current $2 / $10 provider price anchor; first Claude cost/performance test
• GLM-5.2 — $1.40 / $4.40 per 1M, July value pick to test for long-context coding
• Kimi K3 — $0.30 cache-hit / $3.00 cache-miss input, $15 output, Kimi flagship eval lane
• Kimi K2.7 Code — $0.19 cache-hit / $0.95 cache-miss input, $4.00 output, cheaper routine Kimi coding API lane
• MiniMax M3 — Standard PAYG from $0.60 / $2.40 per 1M, value coding-agent lane to test

Bottom line: This is the production spend band. Use it for daily work, then escalate only when the task proves it needs a premium model.

Premium Tier: $5+/1M Tokens

Price: $5.00+ per million input tokens Best for: Complex research, enterprise workloads, premium arbitration, and tasks where a better answer is worth the bill

Models:

• Claude Opus 5.5 — current premium Claude route; use the Opus 5.5 owner guide for live access, pricing, and benchmark evidence
• Claude Fable 5 — $10 / $50 per 1M, restored guarded escalation; revisit after Opus fails only if access, retention, and guardrail tests pass
• GPT-6 Sol — current OpenAI hard-work route; see the GPT-6 Sol/Luna owner guide before committing spend
• GPT-6 Astra — planning evaluation route; read the Astra planning evidence before generalizing beyond planning tasks

OpenAI family: GPT-6 Sol and Luna are the current hard-work and value routes in this comparison; GPT-6 Astra has a separate planning evaluation. Keep current access and price claims on their owner pages.

Current price anchors are $4/$20 for Opus 5.5, $2/$10 for GPT-6 Sol, and $0.10/$0.50 for GPT-6 Luna, with cache-read rates owned by the linked guides. Verify context tiers, plan access, and checkout before purchase.

Bottom line: Do not promote premium as a default. Measure fallback/refusal behavior, cached-input economics, retention requirements, and cost per successful task.

Historical OpenAI and Claude records

GPT-5.5, GPT-5.6, and Opus 5 remain useful for pinned integrations and dated benchmark comparisons. Their prices and scores belong to the historical record; they do not define the current premium recommendation.

Quick Selection Guide

Methodology

Pricing: Current official list prices, with subscriptions and API rates kept separate.

Benchmarks: Exact benchmark names and variants, with independent and vendor evidence labeled separately.

Use cases: Provider specifications plus explicit local-evaluation gaps; no implied hands-on result without an artifact.

See /verify/methodology/ for full verification standards.

For security-task caveats, see the LLM app-hacking field test. It separates generic model price/performance from cost per confirmed exploit on one deliberately vulnerable app.
