It&amp;rsquo;s priced at $2.50 per million input tokens and $10 per million output tokens, and it&amp;rsquo;s reachable through Cohere&amp;rsquo;s own API as well as AWS Bedrock, Azure AI Foundry, and Oracle Cloud, the same multi-cloud distribution Cohere has relied on since Command R.&lt;/p&gt;
&lt;p&gt;Cohere continues to sell mainly to enterprises building internal search and document-QA systems rather than consumer-facing products, and Command A2&amp;rsquo;s improvements are aimed squarely at that audience: better grounding on retrieved documents and more reliable citation of sources, both areas where the company has staked its reputation against larger labs with flashier general-purpose models.&lt;/p&gt;</description></item><item><title>Mistral Large 4</title><link>https://bestofai.io/models/mistral-large-4/</link><pubDate>Sun, 19 Jul 2026 00:00:00 +0000</pubDate><guid>https://bestofai.io/models/mistral-large-4/</guid><description>&lt;p&gt;Mistral Large 4 replaces Large 3 as Mistral AI&amp;rsquo;s proprietary flagship, roughly eight months after that model shipped in December 2025. It&amp;rsquo;s a 190 billion parameter dense model with a 256,000 token context window, priced at $2 per million input tokens and $8 per million output tokens through Mistral&amp;rsquo;s own La Plateforme as well as Azure AI Foundry and AWS Bedrock. Mistral says the gains over Large 3 are concentrated in coding and multi-step reasoning, an area where the company has been trying to close the gap with GPT-5.6 and Claude Sonnet 5 rather than compete on raw scale.&lt;/p&gt;</description></item><item><title>Qwen4-Max</title><link>https://bestofai.io/models/qwen4-max/</link><pubDate>Sun, 19 Jul 2026 00:00:00 +0000</pubDate><guid>https://bestofai.io/models/qwen4-max/</guid><description>&lt;p&gt;Qwen4-Max is Alibaba&amp;rsquo;s top-tier proprietary model, sitting above the open-weight Qwen3 family the company keeps releasing on Hugging Face. Unlike those, Qwen4-Max is closed and only reachable through Alibaba Cloud&amp;rsquo;s API, Qwen Chat, or partner platforms, priced at $1.20 per million input tokens and $4.80 per million output tokens. It takes text and image input, carries a 1 million token context window, and Alibaba has been positioning it directly against GPT-5.6 and Gemini 3.5 Pro in its own benchmark comparisons.&lt;/p&gt;</description></item></channel></rss>
