Compare AI Models & Tools

Cut through the marketing. These comparisons focus on accepted-result cost, evidence quality, and when each option makes sense. Current model routes point to Opus 5.5 and GPT-6 Sol/Luna owner pages; older model rows remain dated evidence.

The aihackers approach: No affiliate links. No sponsored placements. Just verified specs and honest tradeoffs.

For current subscription windows and offer eligibility, see the September 2026 AI launch offers. Offers are account- and date-specific and do not decide the model ranking.

Model Comparisons by Tier

Choose based on your budget and performance needs:

Model Tier Deep Dives

Budget Tier: Under $1/1M Tokens

GPT-5 mini ($0.25/1M) — Cheapest OpenAI option, reliable ecosystem
Gemini 3 Flash ($0.50/1M input, $3/1M output in the current structured source) — high-context Gemini value lane

GPT-6 Luna ($0.10/$0.50 current price anchor) — high-volume OpenAI lane; use CAR, not list price

DeepSeek V4.1 Flash — direct-API and MIT-weight value candidate; verify peak/off-peak rates on the owner guide. 0731 and preview evidence stays historical and does not evaluate V4.1

Kimi K2.7 Code ($0.95/1M cache-miss input) — cheaper routine Kimi coding lane Claude Haiku 4.5 ($1.00/1M) — Fastest responses, Anthropic reliability

Bottom line: Start with a low-cost lane, then measure accepted patches, retries, and review time. A single benchmark cannot establish a percentage of total frontier capability.

Mid-Range Tier: $1-$3/1M Tokens

• Claude Sonnet 5 ($2/$10 current provider anchor) — first Claude cost/performance test
• GLM-5.2 ($1.40/1M input, $4.40/1M output) — historical July comparison; GLM-5.3 documentation covers the newer revision, which these scores do not evaluate
• Kimi K3 ($0.30 cache-hit / $3.00 cache-miss input, $15.00 output) — latest Kimi flagship and 1M-context test 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) — value coding-agent lane to test

Bottom line: The production sweet spot is no longer one model. Start with the provider/tooling lane that fits your workflow, then measure cost per successful task.

Premium Tier: deliberate escalation

• Claude Sonnet 5 ($2/$10 current provider anchor) — start here for routine production
• Claude Opus 5.5 ($4/$20; $0.20 cache read) — current premium Claude route
• Claude Fable 5 (see current owner terms) — restored guarded escalation; revisit after Opus 5.5 fails only if access, retention, and guardrail tests pass
• GPT-6 Luna ($0.10/$0.50; $0.01 cache read) — bounded OpenAI route
• GPT-6 Sol ($2/$10; $0.20 cache read) — harder OpenAI route
• GPT-6 Astra — planning-specific evaluation; do not generalize from the planning evidence without a matching task

GPT-5.5, GPT-5.6, and Opus 5 remain available as historical or pinned-integration records. Their old prices and benchmark scores do not define the current premium recommendation.

Bottom line: Premium models are escalation tools. Test fallback/refusal behavior, cached-input economics, and data policy before routing production work.

How to Choose

Start with the question: What’s your constraint?

Cost is everything → Best Free AI Coding Tools Right Now — Zero-dollar options

Need production reliability → Mid-range tier — Best balance of capability and cost

Maximum reasoning required → Premium tier — That final 5% of capability matters

Not sure? → Start free, then see Smart Spend for upgrade guidance

Comparison Methodology

Pricing: List prices from official sources, verified monthly
Benchmarks: Use How to Read AI Benchmarks to match each test to the task, then treat results as shortlist evidence rather than a purchasing verdict

Use cases: Based on actual testing, not spec sheets
Updates: Revisited when new models drop or pricing changes

See /verify/methodology/ for full verification standards.
