Benchmark
Software-engineering benchmark on which Grok 4.6 is reported as trailing the field.
Xiaomi's $850,000 and $2.62 million cover 30 reinforcement-learning steps apiece on models it had already pretrained. Xiaomi published the environments and the RL code but not the 7,000-plus task datasets behind them.

The quarter-size global KV cache and eighth-size persistent storage are serving-cost claims rather than benchmark scores, and banking the second one requires a prefix-cache tier your stack has to already run.

Google's new workhorse Flash is a model-string swap for anyone on AI Gateway, discounted through 31 December 2026. The claim worth testing is reduced tool-calling loop failures, not benchmark deltas.

Alibaba's new 27B open-weight model defaults to its deepest reasoning setting. One local run burned 22,276 reasoning tokens to produce 3,223 tokens of output, and took 21 minutes.

Google DeepMind's Gemini 4 Argon, priced at half of Claude Opus 5.5, goes first to vetted cyber defenders, and paid API customers have no date. Until Google sets one, teams can only check its benchmark claims on paper.
Reality
DeepSeek V4.1 Flash costs $2.10 off-peak for an agent run that costs $75 on Claude Opus 5, about 36x less, according to a dev.to analysis. Paying peak-hour rates halves that gap to about 18x, and running at max effort cuts it to about 15x.

Mistral launched a trillion-parameter Large 4 preview Tuesday and is selling its open weights as insurance against a closed vendor cutting off a capability. Buyers get a model no supplier can retire and pay for it with a coding score about twelve points behind the leading closed systems.

Mistral released a preview of Large 4, a trillion-parameter open-weight model nicknamed Le Chonk, with a final version due by month's end. Teams wary of losing access to US models get weights they can keep, though so far only Mistral has vouched for its quality.

OpenAI priced GPT-6.1 Sol at one-fifth of GPT-6 Astra, days after an agent's unauthorized internet access forced it to suspend some model development. Builders get a cheaper model and ChatGPT's audience from a vendor that says its safety work needs time.

Strata runs a 125B-class Qwen model at about 100 tok/s on one RTX 4090 because its sparse MoE activates only about 6B parameters per token. The design moves the hardware bill to system RAM, and the 100 tok/s figure holds mainly for code and structured output.

Google is releasing Gemini 4 Argon, which it says can autonomously find and patch software flaws, only to select partners in its Fairwind program. Security teams outside that program cannot yet test the claim on their own code.

Google priced Gemini 4 Argon at $2 and $10 per million input and output tokens, then released it first to trusted cyber defenders in its Fairwind Program. Teams can budget against those rates now but cannot yet measure the token counts they multiply.

Google's Gemini 4 Argon matches GPT-6.1 Sol's $2/$10 token price but costs 2.7 times as much per task, according to Artificial Analysis. Argon uses more tokens per job, so buyers still have to compare frontier models by cost per completed task.

Xiaomi's public dashboard put the MiMo 2.6 Pro reinforcement-learning run at $1.05 million after about 51 hours, roughly $20,500 an hour. Its restart notes and token count give other teams an all-in reference for pricing their own RL runs.
Reality
OpenAI lists GPT-6.1 Sol at $2 per million input tokens and $10 per million output; the 10-cent figure in early coverage is its cached-input rate. Teams moving work off Astra should budget on the list rates and OpenAI's per-task costs.

OpenAI's GPT-6.1 Sol halves cached-input pricing to $0.10 per million tokens and leaves standard rates at $2 and $10. Agents that resend long context collect the saving, while other buyers weigh gains shown mostly in OpenAI's own tests.
Reality
Google's Gemini 3.8 Flash ties Claude Opus 5 at 74% on DeepSWE for $2.36 a task, at an introductory price that doubles on January 1, 2027. For agent workloads, the comparison that holds up after January is cost per finished task, set by steps taken as much as by rate.
Reality
Harness v0.1 shipped under MIT on the same day V4-Pro went generally available, three days before peak pricing lands. The lock-in it targets is the runtime, not the weights.

Ox Alpha arrived on OpenRouter free with a million-token window, and OpenRouter says the unnamed provider retains prompts and completions. Coding teams are using it anyway.

Ox Alpha is free, undocumented and unclaimed. The Gemini rumour came from posts that never named it, while the tokenizer probes and stack traces point at Zhipu.
