July 8, 2026 — Gemini 3.5 Pro review and pricing pages
Factual. The June 30, 2026 claim that Google released "Gemini 3.5 Pro" was fabricated. Both source URLs originally cited for the launch and its benchmark figures now return 404, Google's own Gemini API pricing and model documentation still list Gemini 3.1 Pro as the current flagship, and Google DeepMind's model hub lists "Gemini 3.5 Pro" as coming soon, not shipped. The review and pricing page have been withdrawn and replaced with correction notices; see the correction and the pricing correction.
July 8, 2026 — GPT-5.6 launch coverage
Factual. The July 1, 2026 claim that GPT-5.6 (Sol, Terra, Luna) had reached general availability — "to everyone… no partner list and no waitlist" — was false. OpenAI's own developer docs still describe access as limited to "select trusted partners in preview," with Sol, Terra, and Luna remaining in the same ~20-partner, government-vetted preview that opened June 26, 2026; OpenAI has not confirmed a general-availability date. Corrected across the launch article and the pricing page.
July 8, 2026 — Claude Sonnet 5 max output
Factual. Claude Sonnet 5's max output was recorded as 200,000 tokens. The correct figure, per Anthropic's own Models overview documentation, is 128,000 tokens — which ties Claude Opus 4.8's max output rather than exceeding it, and is double Sonnet 4.6's rather than triple. Corrected across the review, the pricing page, and every comparison that cited the old figure.

Stale. Refreshed Gemini lineup coverage to reflect the May 19, 2026 release of Gemini 3.5 Flash and the announcement of Gemini 3.5 Pro for June 2026. Updated references throughout to match the current Google model lineup.

January 15, 2026 — Coding assistants shootout
Stale. Added a note that Cody and Windsurf shipped major updates in mid-January 2026 and the comparison may warrant re-checking against current versions.
January 8, 2026 — GPT-5, reviewed
Stale. Updated throughput numbers after OpenAI's January API update improved vision throughput by roughly 30%. Tokens-per-second on text-only tasks unchanged.
2025
