OpenAI slashes GPT-6.1 Terra 50% and discounts up to 90% to pull enterprise customers off Anthropic
Wednesday, October 28, 2026: OpenAI launched GPT-6.1 Terra at $1/$5 per million tokens — half of GPT-6.1 Sol — while simultaneously offering enterprise discounts of up to 90% that moved Replit, Rippling and a US bank’s ChatGPT seats off Anthropic, days before ANT’s IPO roadshow.
The price offensive lands the same week Anthropic’s S-1 revealed an $80.7 billion first-half net loss (mostly non-cash convertible-note charges) and a slowdown in Q3 revenue growth — the first public test of whether the open-weight pricing floor, not lab ambition, now sets frontier API prices for Indian enterprises.
GPT-6.1 Terra went live Tuesday via ChatGPT and the API at $1 per million input tokens and $5 per million output tokens ($0.05/M cached input) — exactly half of GPT-6.1 Sol’s launch pricing. It is a 6-model family per Artificial Analysis (with a "Max" tier at 48 on their Intelligence Index), built for computer-use, visual reasoning and software-development workflows. On Agents’ Last Exam it scored 60.0%, 15 percentage points above GPT-5.6 Terra at medium settings; Terminal-Bench 4.0 score was 50.3%. OpenAI billed it as 3x faster than prior agent models for automated computer-operation tasks.
The discount war ran alongside the model launch. The Information (Saturday) reported OpenAI discounting aggressively to pull enterprise customers away from Anthropic. TNW cited that Replit moved most of its AI spending to OpenAI after an offer of more than 30% off a contract worth over $100 million a year, with Anthropic refusing to extend its earlier discount without bigger token commitments. The Decoder said Rippling’s coding work shifted to 52% on OpenAI (up from 16% in May) while Anthropic’s share fell from 57% to 18%. DataCamp’s CEO reported OpenAI cut his costs by 80 to 90 percent; a US bank with over $7 billion in assets had ChatGPT seats doubled to 500 at no extra charge, paying under $7 per user instead of the usual $20 or more.
Anthropic’s S-1, filed Monday October 26, provides the timing context. Revenue hit $16.3 billion in H1 2026 (+1,304% YoY from $1.16 billion), but the company reported an $80.7 billion net loss — roughly $72.4 billion of which was non-cash accounting adjustments from convertible-note fair-value movements, leaving an operating loss of approximately $693 million. Nearly $9 billion went to compute and infrastructure expenses in H1 alone. About 1,900 enterprise customers generated at least $1 million each in annualized revenue as of September. An investor memo flagged a slowdown in revenue growth from Q2 to Q3. Valuation dropped to roughly $1.5 trillion from about $2 trillion a week earlier, with seven co-founders retaining 50.1% voting control through Founder LLC. The SEC filing listed Goldman Sachs and Morgan Stanley as lead underwriters for a Nasdaq listing under ticker ANT, with a mid-to-late November roadshow window.
For Indian enterprises, the two-front offensive arrives as both procurement opportunity and planning problem. Near-term unit economics improved materially: Terra at $1/$5 halves the agentic-mid-tier price bracket. But the deeper lever — committed-enterprise discounts of up to 90% — means Anthropic’s biggest accounts face massive switching incentives during their IPO preparation window. Indian GCCs, BFSI teams and IT-services buyers currently routing Claude spend should re-test multi-model pricing terms immediately. The S-1’s fixed-cost burden (~$9B/yr compute H1) creates margin pressure; if Anthropic pivots to volume for roadshow credibility, the pricing-floor thesis gains another data point. Either way, the open-weight lane remains critical: Mistral Large 4 open weights arrive in the final countdown (HF card counts to Oct 31; license still unpublished), and Kimi K3.1 Pro released Friday, scoring 4th on Artificial Analysis (55) behind Opus 5.5, Sonnet 5.5 and Muse Wonder Full, with weights planned Nov 4 — the highest-scoring open-weight ever if it ships, shrinking the open-vs-closed gap from 12 to 3 points.
Markets, for their part, closed flat on expiry day: Sensex 73,598.67 (-0.01%), Nifty 22,749.75 (-0.02%), with media +3.6%, pharma +2%, smallcaps +2.7% leading while IT dragged (-0.5%). FPI sold ₹1,462 crore Monday; October outflows ~$4.75 billion; YTD selling reached a record $32.56 billion. Brent crude hovered near $116, near a six-month high after attacks on Saudi Arabia, though it remained well above last year’s levels. USD/INR held just below 95, cushioned by Jio IPO-linked inflows. Jio Platforms shares list today (BSE/NSE). Tomorrow brings the Fed policy decision (tonight IST) and Microsoft/Alphabet earnings after the US close — the first big test of whether the AI-capex boom is paying off. Credit insurance against a CoreWeave default now trades at over 10% a year, underscoring nervousness in the financing markets.
