GPT-6.1 Terra: Agent-for-Work at a Tenth of the Price, Rated 'Critical'

OpenAI released GPT-6.1 Terra today (mid-tier in the Luna/Terra/Sol/Astra lineup; the tier was conspicuously left out of last month's GPT-6 launch — it had been cancelled as GPT-6.1 Astra after failing internal safety tests). Headline capability is computer use: screen-reading, clicking, typing across apps.

What happened

Pricing $1/M input, $5/M output — half the price of the GPT-5.6 Terra it replaces, one-tenth of Astra's; 1.05M-token context; rolling out in ChatGPT Work, Codex, GitHub Copilot, and the API. OpenAI's own numbers: +15 points on "Agents' Last Exam" at ~1/3 the task cost of its predecessor, matching Astra at 1/10 price, 3x task speed; error rate on adversarial "error-inducing" prompts fell from 53.6%→16.7% at low effort. Terra is rated "Critical" cybersecurity capability under the Preparedness Framework — same protections as Astra/Sol. Separately confirmed today: OpenAI's models are coming to Google Cloud/Antigravity (Ars) — GPT-6.1 Astra, Sol, Luna there "in coming weeks."

The caveats that matter

Every performance claim here is vendor-reported; no third-party eval exists yet — and the "matches Astra at 1/10 price" line comes with OpenAI's own caveat that Sol/Astra still win the hardest coding tasks. The cancellation-then-relaunch sequence (GPT-6.1 Astra cancelled for safety failures → Terra now ships with Astra's safety stack) deserves keeping on the watchlist: it's the second time this month OpenAI's safety process visibly bit, then got worked around by re-scoping rather than by third-party verification.

What it means

Read alongside Anthropic's S-1 (story 1): both frontier labs are now racing for the same prize — the boring, high-volume enterprise task layer — and price is the weapon (Terra is 50–75% cheaper than anything above it). The "Critical cyber" rating on a cheap, fast, computer-operating model is the combination security teams will be arguing about for quarters: capability at Astra level, cost at Luna level, deployed at volume into accounting, procurement, and browser automation — exactly where the PHP2Shell-class attackers operate. --- ## Quick hits & watchlist - Iran/Mideast: Brent eased to $115.15 Mon (−1.35%) after Friday's $116.72 close; Houthis claimed strikes on East-West pipeline stations and Riyadh airport (no Saudi confirmation); Qatari mediators arrived in Tehran, Saudi/Turkey/Pakistan officials meeting in Tehran. DNI memo (via Axios) warns Iran in "advanced stage" of planning attacks on US citizens — embassies cutting staff. NYT: US/Israel strike plans timed after Nov 3 midterms — the election is priced into oil. - Ukraine: Oleshky local ceasefire was set for Oct 27 (now reported Oct 29 by POLITICO; Russia accuses Ukraine of 18 artillery strikes on the town ahead of it — both sides pre-positioning blame). Kremlin "trilateral preparations" remains single-source aspiration. - France: 1,314 arrested Sat amid Macron's ban on non-union demonstrations; fast-track jailing underway. - US midterms (8 days): DOJ sues Alaska pre-emptively to block certifying a Peltola win over Dan Sullivan (Trump: "I'm the one that said do it"); GOP voter-fraud lead Scott Presler caught running a multi-voter residency scheme out of his own house (Bulwark); Reuters finds candidates A/B-testing campaign messages against AI chatbots. - Ebola (DRC): >4,600 deaths, largest Bundibugyo-strain outbreak ever; "Tumaini" vaccine trial started. - Tor: the 333 hijacked exit nodes (last run) — no new attribution reporting; assume plaintext-protocol exposure during Oct 18–21 window. - Microsoft: offered voluntary buyouts to ~60,000 employees (~27% of workforce) today — AI capex cost-cutting ahead of Wednesday earnings (Reuters/Bloomberg/AP all confirm). Open questions for next run: whether CISA adds the PHP2Shell CVEs to KEV (that's the official "confirmed" bar); whether the two imminent PHP emergency patches fix the CVE-2026-115560 path; TSE response to Bolsonaro's annulment petition; Serbia's final seat allocation and PM naming; whether Amazon's Leo speed claims survive first independent benchmark; whether any independent eval org (METR et al.) gets hands on Terra; whether the Senate SpaceX letters produce documents; Nov 3 vs Iran strike window.
