Anthropic
Claude Code Now Prices Sonnet 5.5 Cache Reads at $0.10 per Million Tokens
Anthropic just changed how Claude Code prices Sonnet 5.5 cache reads, and it’s worth a look if you track token spend. Cache reads are now priced at $0.10 per million tokens instead of $0.20.
The update applies to /cost, the status line, the max-budget settings, and the SDK cost figures. Your in-tool estimates and budget guardrails now use the new rate.
For cost owners, that means the numbers your teams see in Claude Code line up with the updated cache read pricing. If you set budget caps or build forecasts from these figures, you’ll want to refresh your assumptions.
Idle Compaction in Claude Code Helps Long Chats Avoid Wasted Tokens
Claude Code has a new trick for keeping long conversations cheaper: idle compaction. A chat that’s grown past 200K tokens can now be compacted before the one-hour prompt cache expires.
That timing matters because it cuts down on reprocessing and token waste. Once the cache expires, a long conversation would otherwise have to be processed again.
The release also adds /usage warnings for large tool results and max effort. On top of that, there are updated cost and token controls. Together, these give your teams earlier signals about what’s driving spend, so you can step in before a session gets expensive.
Claude Code Adds Cache Creation Metrics and Smarter Usage Warnings
Claude Code v2.1.300 gives you a clearer look at where your tokens go. It adds separate cache creation token metrics, so cache activity is easier to track on its own.
It also brings GenAI semantic-convention telemetry. In addition, /usage warnings are improved for max effort, workflows, always-on context, and large tool results.
There’s more for optimization, too. The release adds workflow controls and model selection hooks that can help tune token spend and agent efficiency. If you’re building dashboards or setting team guardrails, this update gives you more to work with.
Claude Code v2.1.301 Brings Better Token Telemetry and Fewer Wasted Credits
Anthropic’s latest Claude Code release is all about visibility and avoiding waste. It adds OpenTelemetry tracing guidance, plus more detailed token and usage event data.
It also adds safeguards for retry and compaction behavior. Beyond that, fixes and improvements aim to reduce unnecessary token usage. They also help avoid wasted credits during model switching and compaction.
With richer usage events, you can see more clearly what’s consuming tokens. The safeguards then help keep avoidable spend from piling up.
More Accurate Token Counts for Claude Code Behind the Claude Apps Gateway on Amazon Bedrock
Anthropic tightened up token counting for Claude Code behind the Claude apps gateway on Amazon Bedrock. It now uses AWS CountTokens instead of a one-token model request.
The change improves usage estimation for context and large-file reads. Those are the spots where numbers can drift when you’re trying to understand what a session costs.
If your teams run Claude through Bedrock, you’ll get better cost accuracy and observability from this update.
Claude Code v2.1.294 Tightens Hooks That Block Unwanted Actions
Claude Code v2.1.294 is a small release with a useful guardrail angle. It tightens prompt and agent hooks that can block undesirable actions, giving you better policy control over tool usage.
It won’t change your bill by itself. Still, stronger guardrails can help cut down on wasted or unintended model and tool calls. For teams trying to keep agent activity in check, that’s a handy addition.
Claude Opus 5.5 and Sonnet 5.5 Are Now in the Gemini Enterprise App
Google just added Anthropic models to Gemini Enterprise. Claude Opus 5.5 and Claude Sonnet 5.5 are now available in the app.
They’re offered in the global, us, and eu locations. Billing is pay-as-you-go, so costs follow your actual usage.
This one’s directly useful for FinOps teams. You can compare workload costs for these models across major regions, all from within Gemini Enterprise.
Gemini 4 Argon Is Now Available in AlphaEvolve
Google has added Gemini 4 Argon support to AlphaEvolve experiments. It’s available in the global, US, and EU regions.
This gives your teams another model choice for code and program generation workloads. Model choice can affect efficiency, cost, and experimentation spend, so it’s something to factor in when planning AlphaEvolve work.
Gemini 3.8 Flash Is Now Generally Available in the UK
Gemini 3.8 Flash just became generally available in the United Kingdom. It comes with in-region data residency and machine learning processing support.
The update is region-specific, but the UK is a major market. If your FinOps strategy includes UK deployments, this can matter for compliance, locality, and efficiency planning.
OpenAI
Asana Made Its Browser Agent 76x Cheaper and 5x Faster in Tests
OpenAI shared a standout cost-efficiency story from Asana. In tests, Asana made its browser agent 76x cheaper and 5x faster using Codex.
It’s a real example of how model and workflow tuning can lead to much lower spend. If you’re looking for proof that optimization pays off, this case study is a good one to share with your engineering teams.
Composer Predictions in Codex Won’t Use Credits During Beta
OpenAI introduced Composer predictions in beta for Codex. The feature suggests the next message in a thread to speed up interactions.
Here’s the part cost watchers will like. During the beta, it doesn’t count toward Codex usage limits or consume credits. Your teams can try a faster workflow without it eating into their usage allowances.
Faster Steering in Codex Helps Redirect Running Tasks Sooner
OpenAI rolled out faster steering in Codex. Follow-up messages can now redirect a running task sooner.
That’s good for efficiency. When a run is heading the wrong way, your team can correct it quickly, which can reduce wasted compute on misdirected runs.
Sophos Cut Threat Investigation Time by 96% with OpenAI Daybreak
OpenAI reported that Sophos used Daybreak to speed up threat investigations. Investigation time dropped by 96%, and 52% of managed detection and response (MDR) cases were automated. Human oversight was preserved.
This matters for efficiency because it shows a big reduction in human and compute time per case. It’s a useful benchmark when you’re weighing the value of AI-driven automation against its cost.
SentinelOne Cut Malware Analysis from Weeks to Hours
OpenAI described how SentinelOne used OpenAI Daybreak to compress malware analysis from weeks to hours. That increased throughput and investigation capacity.
It’s another example of workload efficiency gains from model-driven automation. If you’re building a business case for AI spend, it shows what faster turnaround can look like in practice.
