17 budget AI coding models ranked by output price ($0.28–$5.00/1M), SWE-bench Pro scores, and real-world CodingFleet speed. DeepSeek V4 Flash cheapest ($0.28). MiniMax M3 best open-weight (59.0% Pro). GPT-5.4 Mini fastest (439.8 char/s). Complete value-per-dollar analysis.
Both $15/1M output. GPT-5.4 is faster (242.5 char/s vs 173.3 on CodingFleet) and stronger on benchmarks (SWE-bench Pro +14, Terminal-Bench +16). Sonnet 4.6 counters with 90% cache discounts, no long-context surcharge, and mature Claude Code ecosystem. The real verdict: use both.
Claude Fable 5 now leads ORM queries & DB administration (80.3% Pro, 88.0% Terminal-Bench). Gemini still leads text-to-SQL. Updated June 9, 2026.
Qwen 3.7 Max — Alibaba's "Agent Frontier" — challenges GPT-5.5 and Claude Opus 4.8 with 60.6% SWE-bench Pro, 91.6% LiveCodeBench, and a record-breaking 53.5% SciCode. At $7.50/1M output with Anthropic API compatibility. Full benchmark comparison, Tetris bot real-world test, and the verbosity tax explained.
From 33.4% Verified to 93.9% — Fable 5 breaks 90%. GPT-5.5's 47-day Terminal-Bench reign ends. Track 27 months of AI coding progress with new charts. Updated June 9, 2026.
A heavy AI coding user burning 200M output tokens/month on GPT-5.5 pays $6,000/month. The same workload on DeepSeek V4 Pro costs $174. The benchmarks gap? 3.2 points on SWE-bench Pro. Here's how to build a coding stack that gives you 95% of flagship performance for 3% of the cost.
Claude Fable 5 is the new #1 for game development (80.3% Pro, 88.0% Terminal-Bench, 85.0% OSWorld). Unity C#, Godot, Roblox, Unreal C++ — updated June 9, 2026.
Claude Fable 5 is the new Python coding king (80.3% SWE-bench Pro). Updated June 9, 2026 with full Fable 5 benchmarks.
Every AI model claims a 1M-token context window. But only GPT-5.5 and Claude Opus 4.6 actually use it. We analyzed MRCR v2, NIAH-2, and Graphwalks to show the 60-point gap between the best and worst "1M-capable" models — and which one to trust for long-context coding.
Which frontier AI model tells the truth? 🆕 Claude Fable 5 debuts at #1 on AA-Omniscience (40, 61% accuracy) but with accuracy-driven strategy — higher hallucination than Opus 4.8. GPT-5.4 Mini leads Vectara (5.5%). The reasoning paradox: thinking mode amplifies hallucination 2-3×. Full 19-model ranking.
Can an MIT-licensed open-weight model beat OpenAI's proprietary GPT-5.4? DeepSeek V4 Pro Max does on SWE-bench — at 4.3× lower cost. Full benchmark and pricing comparison.
