What GPT-6.1 Terra Really Costs: Effort Levels, the 272K Line, and CachingGPT-6.1 Terra launched on 26 October 2026 at $1 per million input tokens and $5 per million output tokens, half of GPT-5.6 Terra's input price and well under half of its $12 output price. The list price is only the starting point. Three things decide what a Terra workload actually bills: * Reasoning effort. Reasoning tokens bill as output, and the gap between effort levels is several-fold. * The 272K line. Once a request's input crosses 272,000 tokens, the whole request moves to a higher rat
GPT-6.1 Terra vs GPT-6.1 Sol: Which Tasks Still Need Sol?GPT-6.1 Terra costs half as much per token as GPT-6.1 Sol: $1 per million input tokens and $5 per million output, against Sol's $2 and $10. OpenAI released Sol in late September 2026 and Terra on 26 October, and the Terra launch post puts it close to Sol on several evaluations. Half the price per token is not the same as half the price per task. The difference comes from reasoning effort. At medium, Terra is cheap, fast and good enough for most extraction, screen and document work. When a task
GPT-6.1 Terra vs Claude Sonnet 5.5: Which Mid-Tier Model for Screen and Document Agents?OpenAI released GPT-6.1 Terra on 26 October 2026, four weeks after Anthropic shipped Claude Sonnet 5.5. OpenAI's launch post set Terra against Claude Opus 5.5, but the coverage drew a different line. The Decoder called Terra "OpenAI's closest competitor to Anthropic's mid-tier Sonnet series at half the price", and AlphaCorp called Terra against Sonnet "the real fight for the mid tier". GPT-6.1 Sol and Sonnet 5.5 share the same $2 / $10 price card, so a team choosing a mid-tier model this month i
AIHubMix vs OpenRouter (2026): An OpenRouter Alternative Without the 5.5% Credit FeeOpenRouter and AIHubMix are both one-key gateways to more than 500 models, and on Claude, GPT, Gemini and Grok they charge the same per-token price: the vendor's list price. So the comparison isn't about the sticker price. It's about what you pay on top of it, how open-weight models get routed, which wire protocols one key speaks, and where your fallback rules live. This page lays those differences out, including the places where OpenRouter is the better pick. The short answer * Pick AIH
Kimi K3.1 Pro vs K3.1 Pro Highspeed: Is 2–3× the Speed Worth 2× the Price?Kimi K3.1 Pro Highspeed is not a smarter model. Moonshot AI describes it as K3.1 Pro "with identical model capabilities", running at "approximately 2–3× the speed". At Moonshot's list price it costs exactly twice as much per input and output token. What you buy is wall-clock time, and nothing else. The short answer: pay for Highspeed when a person is watching the stream, as in an interactive coding session or a chat feature your users wait on. Stay on Pro for work that runs unattended or spend
Kimi K3.1 Pro vs Qwen 4 vs Claude Fable 5.5: Front-End Quality, Cost per Task, and the Hype CheckedThree launches converged on the same October week. On 22 October two anonymous models, Kibitz and Kalmia, appeared in Arena's Code Arena a few hours apart. Tokenizer tests tied them to Moonshot's Kimi and Alibaba's Qwen. A day later, Kimi posted a teaser of K3.1 writing a Three.js scene, and soon after the model was out: Moonshot's launch post introduced Kimi K3.1 Pro in the Kimi app, Kimi Code and the Kimi API. On Anthropic's side, a claude-fable-5-5 listing surfaced in a cloud catalogue on 13
GLM-5.3 Prime vs GLM-5.3: Is 2× the Price Worth the Speed?GLM-5.3 Prime is not a new model. It runs the same GLM-5.3 weights in a faster serving mode: Alibaba Cloud Model Studio's Prime mode, which promises 1.5 to 2 times the output speed of the standard API. The answers should be the same quality. What you pay extra for is tokens per second. On AIHubMix, glm-5.3-prime costs $2.35 per million input tokens and $8.23 per million output tokens, about 2.1× what GLM-5.3 costs today. The short answer: * Worth it when a person or an agent loop sits waiti
MiniMax M3.1 Flash vs DeepSeek V4.1 Flash vs Claude Haiku 5.5: One Bug Fix, Three BillsThree cheap coding models shipped within four weeks of each other: DeepSeek V4.1 Flash (with its 1017 update), Claude Haiku 5.5, and MiniMax M3.1 Flash, which spent its first week as the anonymous Space Bunny. All three have a 1M-token context window and cost between $0.10 and $0.17 per million input tokens. So which one should you use for routine coding? AIHubMix gave all three the same bug fix, three times each, through one API key. Each model fixed the bug correctly every time, but the bill
DeepSeek V4.1 Flash 1017 vs V4 Pro: Is the Flash Enough Now?DeepSeek's lineup has an odd shape this autumn. V4 Pro 0813 is the bigger, pricier model: at peak hours its output costs $3.96 per 1M tokens, 3.3 times the Flash's $1.20. But the Flash has been retrained twice since Pro's August release, and the October 17 update, V4.1 Flash 1017, now outscores Pro on every agentic and coding benchmark DeepSeek publishes for both. So is there any coding or agent task left where Pro is worth the premium? By DeepSeek's own numbers, very few. Pro keeps a narrow l
DeepSeek V4.1 Flash 1017 vs Claude Haiku 5.5: Which Cheap Model for Terminal Coding Agents?Ten days apart, the two cheapest serious agent models of October 2026 arrived from opposite directions. Anthropic shipped Claude Haiku 5.5 on October 7 at $0.10 input and $0.50 output per 1M tokens, pitched as the subagent that sits under Sonnet and Opus. DeepSeek answered on October 17 with V4.1 Flash 1017, an update aimed squarely at end-to-end coding work. The decision comes down to one task: a terminal coding session in Claude Code, where the agent reads files, runs tests, and edits code o
