AI spending can run negative. Qodo’s CEO built an ROI equation to fix it.

The New Stack 3 weeks ago 24

Qodo is limiting internal AI token usage while reporting faster pull requests and fewer bugs from its AI-powered SDLC and customer-facing infrastructure. The cap is $10,000 worth of tokens per month for engineers, while Qodo says its AI infrastructure spend is growing about 5x year over year. Qodo’s approach shifts AI investment decisions toward tracking benefits versus costs (and can support pulling back from automation when ROI is negative), instead of pushing unrestricted AI consumption.

OpenAI cut GPT-6 token prices in half. The bigger lever may be the cache.

The New Stack 3 weeks ago 47 ● 8 sources

OpenAI released GPT-6 Sol and GPT-6 Luna as cheaper versions of GPT-6 Astra with closer alignment to the flagship than the earlier GPT-5.6 Sol variant. API prices for Sol and Luna are down 50% compared with GPT-5.6 counterparts, including 58% lower output-token prices for Luna. OpenAI also added higher default prompt caching, more flexibility to change reasoning effort and tools without breaking cached context, and a Prompt Caching Dashboard to help developers diagnose and reduce token costs further.

The plunging price of thought

TLDR 3 weeks ago 51 ● 7 sources

The issue reports that the cost of achieving a given level of AI performance has dropped about 47% per quarter over the past three years. The article argues that cheaper AI can lead to higher total spending by enabling more agents, while harder tasks still get more expensive even as capability improves. As a result, organizations may spend more overall and allocate more budget toward difficult work rather than only optimizing per-call price.

User benchmark: Nate Herk prefers Opus on 7 of 8 jobs (but slower/more expensive)

YouTube 3 weeks ago 47 ● 2 sources

Nate Herk reportedly preferred Opus on seven of eight usable jobs, but Opus took longer and cost more than Sol. Opus required about 8h40 and $213 compared with Sol’s 5h51 and roughly $74. The takeaway is that model selection should be based on end-to-end workflow outcomes rather than isolated benchmark numbers.

Anthropic launches Claude Opus 5.5 with new token pricing

Anthropic 3 weeks ago 29 ● 8 sources

Anthropic launched Claude Opus 5.5, positioning it as the first release in its Claude 5.5 model family. Default usage is priced to cost 40% less than Opus 5, with input tokens at $4 per million and output tokens at $20 per million. Access and limits also change, including higher five-hour usage limits for several plans and rate-limit reset for subscription users.

OpenAI Cuts Prices in Half With GPT-6 Sol and Luna

Trending Topics 3 weeks ago 50 ● 8 sources

OpenAI released GPT-6 Sol and GPT-6 Luna as cheaper-to-run variants built on GPT-6 alongside Astra. Sol now costs $2 per million input tokens and $10 per million output tokens, down from $4 and $20 respectively. The lower prices and revised prompt caching reduce per-task costs and make the models more cost-competitive for agent-style workflows, though independent tests show mixed performance and some drops on knowledge-work benchmarks.

OpenAI Releases GPT-6 Sol and Luna: 50% Cheaper API Pricing and Benchmarks

MarkTechPost 3 weeks ago 27 ● 8 sources

OpenAI released GPT-6 Sol and GPT-6 Luna as deployable, API-only additions to its GPT-6 model lineup. GPT-6 Sol and GPT-6 Luna API pricing was cut by 50% versus GPT-5.6 promotional pricing, with Sol at $2/$10 and Luna at $0.10/$0.50 per 1M tokens for input/output. The change lowers inference costs and adds improved prompt caching controls that can discount cached input up to 90% and reduce prompt tokens needing fresh processing by more than 50%.

What AI slowdown? OpenAI, Anthropic release dueling models as price wars heat up

Fortune 20 ● 7 sources

OpenAI and Anthropic released cheaper versions of their top AI models within hours of each other amid increased competition and business cost scrutiny. Anthropic said Claude Opus 5.5 runs at about 40% less cost than Opus 5, and OpenAI cut API costs by 50% for GPT-6 Sol and GPT-6 Luna versus its Astra predecessor pricing. The pricing pressure shifts customers toward lower-cost “everyday” models and forces both labs to pass efficiency savings through rate limit and API price cuts, potentially squeezing future profits.
