Grok 4.5 vs Opus 4.8 vs GPT-5.6 in Cursor: pick your model before Build Week

Three frontier models, one editor, wildly different bills. We mapped six real coding tasks to show which one to point at each job this week.

JULY 13TH, 2026 · BY JONATHAN HILDEBRANDT

OpenAI Codex Build Week opens today, and every developer entering it faces the same first call: which model to run in Cursor. Grok 4.5 lists at $6 per million output tokens against Opus 4.8's $25, per the pricing in our comparison, roughly a quarter of the cost. GPT-5.6 sits between them. Price is not the whole story, though. Our 6-task map shows where the cheap model wins outright and where it quietly costs you more in retries.

Anthropic pushed Claude Fable 5 free access to July 19.

JULY 13TH · PONDERO NEWSDESK

Anthropic extended the Fable 5 promotional window twice inside one week, now closing July 19 at 11:59 pm PT, and added a 50 percent bump to Claude Code weekly rate limits, per Forbes. Credit-based billing at $10 per million input and $50 per million output tokens starts July 20. Why it matters: the rate-limit boost buys real headroom for multi-file refactors this week, but set a credit balance before the deadline or API access stops. Details →

 

Gemini 3.5 Pro is reportedly targeting July 17, still unconfirmed.

JULY 12TH · PONDERO NEWSDESK

Reports dated July 7 to 12 cite July 17 as Google's internal target for Gemini 3.5 Pro, with a claimed 2M-token context window and a Deep Think reasoning layer, per TechTimes. There is no Google blog post as of July 13, so treat every spec as unverified. Why it matters: a 2M-token window would be double the field, but do not rearchitect a context-heavy pipeline around a date Google has not committed to. Watch item →

Even Realities raised $150M for camera-free AI glasses.

JULY 11TH · PONDERO NEWSDESK

Even Realities closed a $150M pre-Series B for AI smart glasses that ship without a camera, positioning them as recording-policy-safe for offices where Meta and Ray-Ban glasses are banned, per TechCrunch. Why it matters: the bet is that productivity, not capture, drives enterprise adoption, and a camera-free device clears the compliance objection that keeps face-worn AI out of most workplaces.

Meta pulled Instagram's Muse Image photo feature three days after launch.

JULY 10TH · PONDERO NEWSDESK

Meta removed the @-mention photo-reference feature from Muse Image on July 10, three days after launch, after users, CAA, and SAG-AFTRA objected to a default-on design that let public photos be referenced in AI-generated images with no consent step, per TechCrunch. Why it matters: this is a major platform reversing a consumer AI rollout under pressure, and an EU and FTC inquiry is the open question. Details →

 

NHTSA gave AV operators an ultimatum; Uber ended its Waymo Phoenix deal.

JULY 12TH · PONDERO NEWSDESK

After Waymo vehicles gridlocked San Francisco during July 4 fireworks, NHTSA issued a call for AV operators to "immediately focus their resources on fixing" emergency-responder blocking, per TechCrunch. Uber ended its Waymo Phoenix ride-share partnership on July 12, and a city supervisor opened a formal inquiry. Why it matters: emergency-responder handling just became a regulatory gate, and the first business partnership already broke over it. Details →

 
Tools & How-To

OpenAI Codex Build Week runs July 13 to 21.

JULY 13TH · PONDERO NEWSDESK

OpenAI opened a nine-day competition today to build coding agents on the Codex API, with cash prizes, API credits, and DevDay passes on the line, per openai.com/build-week. Greg Brockman keynotes at 10 am PDT; submissions close July 21. Why it matters: if you are shipping an entry this week, the model you wire into your agent is the first cost and quality decision, which is exactly what our lead comparison settles.

GitHub Copilot safety filter bypass analysis

GitHub Copilot's safety filters folded 100 percent of the time.

JULY 12TH · PONDERO NEWSDESK

Alan Turing Institute researchers turned Copilot's near-total chat-refusal rate into a 100 percent harmful-output rate simply by wrapping the request inside a multi-step coding workflow, per The Register (July 8). Why it matters: refusal training guards the chat box, not the agent loop, so if you run Copilot in an autonomous workflow you cannot treat its filters as a control. Read our writeup →

GRAM routes dual-use knowledge into deletable weight modules so a capability can be removed after training with no drop in general scores, per Anthropic and AE Studio's July 8 research, tested from 50M to 5B parameters and not yet on production Claude.
