GPT-6 Sol Review: Half the Cost per Task, Barely Smarter
GPT-6 Sol halves GPT-5.6 Sol’s per-token price, and on the independent Artificial Analysis index it nearly halves the bill per task too: $1.06 against $1.99, for a score of 48 against 47. No model scoring 48 or more finishes a task for less. It is barely smarter than the model it replaces, and Claude Opus 5.5 at high scores 54 for $1.82. In our own build tests Sol was fast, and each of its three builds had a fault you could see.
- +Cheapest per task of any model scoring 48 or more on the Artificial Analysis index at $1.06
- +One index point above GPT-5.6 Sol for 53% of its cost per task
- -One index point above GPT-5.6 Sol — the step is in price rather than capability
- -Claude Opus 5.5 at high scores 54 for $1.82 a task — six points more
Grok 4.7 Review: Same Price, Twice the Cost per Task
Grok 4.7 keeps Grok 4.6’s $2/$6 list price and beats it on every benchmark SpaceXAI published. The bill is another matter. Artificial Analysis measured $3.74 per Intelligence Index task at xhigh, about twice Grok 4.6’s $1.86 at high, for a score of 46 against 44. Claude Opus 5.5 at high scores 54 for $1.82. In our own build tests Grok 4.7 finished last in both rounds it entered.
- +Same $2/$6 list price as Grok 4.6 — with cached input at $0.50
- +Beats Grok 4.6 on every benchmark SpaceXAI published
- -$3.74 per index task at xhigh — about twice Grok 4.6 for two more points
- -GPT-6 Astra and Claude Opus 5.5 at high both score higher for less per task
Claude Opus 5.5 Review: The New No. 1 Costs Less
Claude Opus 5.5 takes sole first place on the Artificial Analysis Intelligence Index, scoring 58 to the 53 shared by Claude Fable 5.1 and GPT-6 Astra. It lists at $4/$20, a fifth under Opus 5. The better story sits one effort level down: at high it scores 54, above every rival, for $1.82 a task. It also won our three-round build-off, and it was the slowest entrant in every round.
- +First of 212 models on Artificial Analysis Intelligence Index v4.3.2 at 58
- +At high effort scores 54 for $1.82 a task — above every rival at any setting
- -At max effort it emits 260M output tokens on the index — about three times the median
- -Max effort costs $5.98 a task — no cheaper than Opus 5 and nearly twice GPT-6 Astra
GPT-6 Astra Review: Frontier Intelligence, Half the Cost
Astra launched to a brutal independent read: intelligence level with the model it replaces, at 2.5x the price. That framing measured cost per token. Measured per finished task — the number you actually pay — Astra completes the Artificial Analysis Intelligence Index for $4,064 where Claude Fable 5.1 needs $10,816, and scores two points behind it. Our own testing found the same speed advantage, and one repeated weakness no benchmark catches.
- +Finishes the Artificial Analysis Intelligence Index for 37% of what Claude Fable 5.1 spends
- +Uses 49M output tokens where Fable 5.1 needs 160M and Opus 5 needs 120M
- -Not the smartest available — Claude Fable 5.1 scores 57 to Astra’s 55
- -Costs more per finished task than the GPT-5.6 Sol it replaces
Claude Code Review 2026: Pricing, Limits, Verdict
Claude Code is the deepest autonomous coding agent available, running Opus 4.8 at 88.6% on SWE-bench Verified with up to 1000 parallel subagents. Here is what it costs and where it falls short.
- +Deepest autonomy of any coding agent
- +Up to 1000 parallel subagents with verification
- -Least predictable cost in the category
- -Barely competes on autocomplete
Claude Opus 5 Review: Smartest, and Most Annoying
Opus 5 tops the Artificial Analysis Intelligence Index at 61 and posted a near-4x jump on ARC-AGI-3, all at the same price as Opus 4.8. Then the reviewers who tested it called it 'brilliant but annoying': it argues with instructions, stops early, does unrequested refactors, and breaks prompt scaffolding tuned for Opus 4.8. One more finding deserves attention — a reported jump in its hallucination rate.
- +Ranked first on the Artificial Analysis Intelligence Index at 61
- +ARC-AGI-3 leap to 30.2% from a 7.8% prior best
- -Argues with instructions and stops before finishing work
- -Reported hallucination rate up 14 points to 50%
Grok 4.5 Review: Opus-Class Coding, Far Cheaper
SpaceXAI's Grok 4.5 isn't the smartest model on the board — Fable 5 and GPT-5.5 still edge it — but it delivers roughly Opus-class coding at ~4.2× fewer tokens and a third of the price, and leads on long agentic runs. The best value in frontier coding today.
- +Opus-class quality at far lower cost
- +~4.2× fewer output tokens than Opus 4.8
- -Not the top model — Fable 5 and GPT-5.5 edge it
- -Heavy lock-in to Grok Build and Cursor
GLM-5.2 Review: Open Weights That Out-Code GPT-5.5
GLM-5.2 is the strongest open-weight coding model yet: MIT-licensed, 744B MoE, 1M context. It beats GPT-5.5 on SWE-bench Pro and trails Opus 4.8 by a point on FrontierSWE — at a fraction of the cost. Our review, with benchmark charts.
- +Strongest open-weight coding model
- +MIT-licensed and self-hostable
- -Falls behind on agentic Tool-Decathlon
- -Hosted API routes data through China
Claude Fable 5 Review: Most Capable, at a Premium
Anthropic's Claude Fable 5 is the most capable model the public can use today — topping SWE-Bench Pro and excelling at vision and long tasks. It is also the priciest major model and ships with hard safety guardrails. Our first-look verdict.
- +Best agentic-coding result to date (80.3 on SWE-Bench Pro)
- +State-of-the-art vision plus stronger long-horizon autonomy
- -Most expensive major model at $10 in / $50 out per million tokens
- -Safety classifiers can block legitimate security research
DALL-E 3 Review 2026: The Most Accessible Image AI
DALL-E 3 inside ChatGPT remains the most accessible high-quality image generator. After hundreds of generations, here's how it compares to Midjourney V8, FLUX.2, and Nano Banana 2.
- +Best-in-class prompt adherence
- +Reads natural-language instructions correctly
- -Less aesthetic than Midjourney for art
- -Limited control over style and parameters
Perplexity Review 2026: Better Than Google for Research?
Perplexity combines real-time web search with AI synthesis and proper citations. After daily use for two years, here's why it's our team's research default and where it still falls short.
- +Excellent source citations with every answer
- +Free tier is generous and useful
- -Search results can be shallow without Pro
- -Pro Search uses credits faster than expected
GitHub Copilot Review 2026: Is It Still Worth It?
GitHub Copilot is the broadest AI coding assistant and the only real option for JetBrains, Visual Studio, Neovim and Xcode, with completions still free. But June's move to metered AI Credits changed the maths, and Claude Code took developer ground.
- +Only major option for JetBrains and Visual Studio and Xcode
- +Understands your GitHub PRs and issues
- -Lost developer ground to Claude Code
- -Cursor still beats it on multi-file editing
Gemini Advanced Review 2026: Worth $19.99?
Gemini Advanced is now Google AI Pro at $19.99/month, running Gemini 3.1 Pro with a 2M-token context window plus Gemini inside Gmail, Docs and Meet. But the flagship Gemini 3.5 Pro is months late, and every upgrade since May landed in the free Flash tier.
- +Gemini 3.1 Pro is genuinely competitive with Claude/GPT
- +2M token context window — the largest available
- -Gemini 3.5 Pro is months late — the Pro tier still runs an April model
- -Every upgrade since May landed in Flash which the free tier also gets
Sora 2 Review 2026: What It Did Best, and Why It’s Gone
OpenAI discontinued Sora on April 26, 2026 and removes the API on September 24 — it is not inside ChatGPT. What Sora 2 did best, why it is gone, and what to use instead, with our May verdict kept as the historical record.
- +Best-in-class physics simulation
- +Synchronized audio (dialogue + sound effects)
- -Standalone Sora app shut down April 26 2026
- -Sora API discontinued September 24 2026
ElevenLabs Review 2026: Eleven v3 Sets the Voice Bar
Eleven v3 supports 70+ languages, inline emotion tags, and the Text to Dialogue API. After producing 40+ hours of AI audio, here's why ElevenLabs remains the leader and where alternatives might fit.
- +Eleven v3 supports 70+ languages with native quality
- +Inline audio tags ([whispers]
- -Pro tier ($99) gets expensive at scale
- -Voice clones require careful source recording
Cursor IDE Review 2026: Worth $20 a Month?
Cursor Pro is $20 a month and Composer 2.5 now draws with Claude Opus 4.7 on coding benchmarks at roughly a tenth of the per-token cost. But SpaceX is buying Cursor, and that is now part of the decision.
- +Composer 2.5 draws with Opus 4.7 at ~1/10 the token cost
- +Best autocomplete on the market
- -VS Code fork only — no JetBrains or Vim or Xcode
- -SpaceX ownership (closed Aug 14) raises model-neutrality questions; OpenAI cuts Cursor off Nov 12
Midjourney V8 Review 2026: The Aesthetic Champion
Midjourney V8 (alpha March 2026) is 5x faster than V7, supports native 2K resolution, and finally renders text reasonably well. After 500+ generations, here's where V8 leads and where FLUX.2 still wins.
- +5x faster generation in V8
- +Native 2K resolution with --hd
- -Subscription-only — no free tier
- -$10-120/month pricing
Claude Review 2026: Plans, Models and Verdict
Anthropic turned the lineup over again: Fable 5.1 replaced Fable 5 at the top on September 1, Opus 5 replaced Opus 4.8 at the same price, and Sonnet 5’s intro pricing has ended. Where Claude leads, where it still struggles, and whether Pro and Max are worth it in September 2026.
- +Best-in-class nuanced writing
- +Fable 5.1 leads long-horizon agentic coding (55.8% Terminal-Bench 4.0)
- -Fable 5.1 is the most expensive frontier model per task ($10/$50 list and heavy token use)
- -Opus 5 argues with instructions and needs prompt re-tuning
ChatGPT Plus & Pro Review 2026: Is It Worth $20?
ChatGPT Plus is still the best $20 in AI and Pro is still a $200 question — now with GPT-6 Astra, Sol and Luna rolling out to both tiers. What changed since our GPT-5.5 hands-on, where Claude still wins, and who actually needs Pro.
- +Frontier models reach Plus
- +not just Pro
- -Pro at $200/mo is steep
- -Astra rollout is staged and cyber tasks are restricted
